When overridden in a derived class, prepares the font table to be compiled into its binary representation.

When overridden in a derived class, converts the font into its binary representation.

Calculates the checksum of a table represented by its bytes.

Only Symbol and Unicode is used by PDFsharp.

CMap format 4: Segment mapping to delta values. The Windows standard format.

This table defines the mapping of character codes to the glyph index values used in the font. It may contain more than one subtable, in order to support more than one character encoding scheme.

Is true for symbol font encoding.

Initializes a new instance of the class.

This table gives global information about the font. The bounding box values should be computed using only glyphs that have contours. Glyphs with no contours should be ignored for the purposes of these calculations.

This table contains information for horizontal layout. The values in the minRightSidebearing, MinLeftSideBearing and xMaxExtent should be computed using only glyphs that have contours. Glyphs with no contours should be ignored for the purposes of these calculations. All reserved areas must be set to 0.

The type longHorMetric is defined as an array where each element has two parts: the advance width, which is of type USHORT, and the left side bearing, which is of type SHORT. These fields are in font design units.

The vertical Metrics table allows you to specify the vertical spacing for each glyph in a vertical font. This table consists of either one or two arrays that contain metric information (the advance heights and top sidebearings) for the vertical layout of each of the glyphs in the font.

This table establishes the memory requirements for this font. Fonts with CFF data must use Version 0.5 of this table, specifying only the numGlyphs field. Fonts with TrueType outlines must use Version 1.0 of this table, where all data is required. Both formats of OpenType require a 'maxp' table because a number of applications call the Windows GetFontData() API on the 'maxp' table to determine the number of glyphs in the font.

The naming table allows multilingual strings to be associated with the OpenTypeTM font file. These strings can represent copyright notices, font names, family names, style names, and so on. To keep this table short, the font manufacturer may wish to make a limited set of entries in some small set of languages; later, the font can be "localized" and the strings translated or added. Other parts of the OpenType font file that require these strings can then refer to them simply by their index number. Clients that need a particular string can look it up by its platform ID, character encoding ID, language ID and name ID. Note that some platforms may require single byte character strings, while others may require double byte strings. For historical reasons, some applications which install fonts perform Version control using Macintosh platform (platform ID 1) strings from the 'name' table. Because of this, we strongly recommend that the 'name' table of all fonts include Macintosh platform strings and that the syntax of the Version number (name id 5) follows the guidelines given in this document.

Get the font family name.

Get the font subfamily name.

Get the full font name.

The OS/2 table consists of a set of Metrics that are required in OpenType fonts.

This table contains additional information needed to use TrueType or OpenTypeTM fonts on PostScript printers.

This table contains a list of values that can be referenced by instructions. They can be used, among other things, to control characteristics for different glyphs. The length of the table must be an integral number of FWORD units.

This table is similar to the CVT Program, except that it is only run once, when the font is first used. It is used only for FDEFs and IDEFs. Thus the CVT Program need not contain function definitions. However, the CVT Program may redefine existing FDEFs or IDEFs.

The Control Value Program consists of a set of TrueType instructions that will be executed whenever the font or point size or transformation matrix change and before each glyph is interpreted. Any instruction is legal in the CVT Program but since no glyph is associated with it, instructions intended to move points within a particular glyph outline cannot be used in the CVT Program. The name 'prep' is anachronistic.

This table contains information that describes the glyphs in the font in the TrueType outline format. Information regarding the rasterizer (scaler) refers to the TrueType rasterizer.

Gets or sets the global font resolver for the current application domain. This static function must be called only once and before any font operation was executed by PDFsharp. If this is not easily to obtain, e.g. because your code is running on a web server, you must provide the same instance of your font resolver in every subsequent setting of this property. In a web application set the font resolver in Global.asax.

Gets or sets the default font encoding used for XFont objects where encoding is not explicitly specified. If it is not set, the default value is PdfFontEncoding.Unicode. If you are sure your document contains only Windows-1252 characters (see https://en.wikipedia.org/wiki/Windows-1252) set default encoding to PdfFontEncodingj.Windows1252. Must be set only once per app domain.

Specifies the flags of AcroForm fields.

If set, the user may not change the value of the field. Any associated widget annotations will not interact with the user; that is, they will not respond to mouse clicks or change their appearance in response to mouse motions. This flag is useful for fields whose values are computed or imported from a database.

If set, the field must have a value at the time it is exported by a submit-form action.

If set, the field must not be exported by a submit-form action.

If set, the field is a pushbutton that does not retain a permanent value.

If set, the field is a set of radio buttons; if clear, the field is a checkbox. This flag is meaningful only if the Pushbutton flag is clear.

(Radio buttons only) If set, exactly one radio button must be selected at all times; clicking the currently selected button has no effect. If clear, clicking the selected button deselects it, leaving no button selected.

If set, the field may contain multiple lines of text; if clear, the field’s text is restricted to a single line.

If set, the field is intended for entering a secure password that should not be echoed visibly to the screen. Characters typed from the keyboard should instead be echoed in some unreadable form, such as asterisks or bullet characters. To protect password confidentiality, viewer applications should never store the value of the text field in the PDF file if this flag is set.

(PDF 1.4) If set, the text entered in the field represents the pathname of a file whose contents are to be submitted as the value of the field.

(PDF 1.4) If set, the text entered in the field will not be spell-checked.

(PDF 1.4) If set, the field will not scroll (horizontally for single-line fields, vertically for multiple-line fields) to accommodate more text than will fit within its annotation rectangle. Once the field is full, no further text will be accepted.

If set, the field is a combo box; if clear, the field is a list box.

If set, the combo box includes an editable text box as well as a drop list; if clear, it includes only a drop list. This flag is meaningful only if the Combo flag is set.

If set, the field’s option items should be sorted alphabetically. This flag is intended for use by form authoring tools, not by PDF viewer applications; viewers should simply display the options in the order in which they occur in the Opt array.

(PDF 1.4) If set, more than one of the field’s option items may be selected simultaneously; if clear, no more than one item at a time may be selected.

(PDF 1.4) If set, the text entered in the field will not be spell-checked. This flag is meaningful only if the Combo and Edit flags are both set.

Predefined keys for cross-reference dictionaries.

(Required) The type of PDF object that this dictionary describes; must be XRef for a cross-reference stream.

(Required) The number one greater than the highest object number used in this section or in any section for which this is an update. It is equivalent to the Size entry in a trailer dictionary.

(Optional) An array containing a pair of integers for each subsection in this section. The first integer is the first object number in the subsection; the second integer is the number of entries in the subsection. The array is sorted in ascending order by object number. Subsections cannot overlap; an object number may have at most one entry in a section. Default value: [0 Size].

(Present only if the file has more than one cross-reference stream; not meaningful in hybrid-reference files) The byte offset from the beginning of the file to the beginning of the previous cross-reference stream. This entry has the same function as the Prev entry in the trailer dictionary.

(Required) An array of integers representing the size of the fields in a single cross-reference entry. The table describes the types of entries and their fields. For PDF 1.5, W always contains three integers; the value of each integer is the number of bytes (in the decoded stream) of the corresponding field. For example, [1 2 1] means that the fields are one byte, two bytes, and one byte, respectively. A value of zero for an element in the W array indicates that the corresponding field is not present in the stream, and the default value is used, if there is one. If the first element is zero, the type field is not present, and it defaults to type 1. The sum of the items is the total length of each entry; it can be used with the Indexarray to determine the starting position of each subsection. Note: Different cross-reference streams in a PDF file may use different values for W. Entries in a cross-reference stream. TYPE FIELD DESCRIPTION 0 1 The type of this entry, which must be 0. Type 0 entries define the linked list of free objects (corresponding to f entries in a cross-reference table). 2 The object number of the next free object. 3 The generation number to use if this object number is used again. 1 1 The type of this entry, which must be 1. Type 1 entries define objects that are in use but are not compressed (corresponding to n entries in a cross-reference table). 2 The byte offset of the object, starting from the beginning of the file. 3 The generation number of the object. Default value: 0. 2 1 The type of this entry, which must be 2. Type 2 entries define compressed objects. 2 The object number of the object stream in which this object is stored. (The generation number of the object stream is implicitly 0.) 3 The index of this object within the object stream.

Beginning with PDF 1.3, there are two separate overprint parameters: one for stroking and one for all other painting operations. Specifying an OP entry sets both parameters unless there is also an op entry in the same graphics state parameter dictionary, in which case the OP entry sets only the overprint parameter for stroking.

(Optional; PDF 1.3) A flag specifying whether to apply overprint for painting operations other than stroking. If this entry is absent, the OP entry, if any, sets this parameter.

(Optional; PDF 1.3) The overprint mode.

(Optional; PDF 1.3) An array of the form [font size], where font is an indirect reference to a font dictionary and size is a number expressed in text space units. These two objects correspond to the operands of the Tf operator; however, the first operand is an indirect object reference instead of a resource name.

(Required) The type of PDF object that this dictionary describes; must be Font for a font dictionary.

(Required) The type of font.

(Required) The PostScript name of the font.

(Required except for the standard 14 fonts; must be an indirect reference) A font descriptor describing the font’s metrics other than its glyph widths. Note: For the standard 14 fonts, the entries FirstChar, LastChar, Widths, and FontDescriptor must either all be present or all be absent. Ordinarily, they are absent; specifying them enables a standard font to be overridden.

The PDF font descriptor flags.

All glyphs have the same width (as opposed to proportional or variable-pitch fonts, which have different widths).

Glyphs have serifs, which are short strokes drawn at an angle on the top and bottom of glyph stems. (Sans serif fonts do not have serifs.)

Font contains glyphs outside the Adobe standard Latin character set. This flag and the Nonsymbolic flag cannot both be set or both be clear.

Glyphs resemble cursive handwriting.

Font uses the Adobe standard Latin character set or a subset of it.

Glyphs have dominant vertical strokes that are slanted.

Font contains no lowercase letters; typically used for display purposes, such as for titles or headlines.

Font contains both uppercase and lowercase letters. The uppercase letters are similar to those in the regular version of the same typeface family. The glyphs for the lowercase letters have the same shapes as the corresponding uppercase letters, but they are sized and their proportions adjusted so that they have the same size and stroke weight as lowercase glyphs in the same typeface family.

It must be one of the following names (ordered from narrowest to widest): UltraCondensed, ExtraCondensed, Condensed, SemiCondensed, Normal, SemiExpanded, Expanded, ExtraExpanded or UltraExpanded. Note: The specific interpretation of these values varies from font to font. For example, Condensed in one font may appear most similar to Normal in another.

(Optional; PDF 1.5; strongly recommended for Type 3 fonts in Tagged PDF documents) The weight (thickness) component of the fully-qualified font name or font specifier. The possible values are 100, 200, 300, 400, 500, 600, 700, 800, or 900, where each number indicates a weight that is at least as dark as its predecessor. A value of 400 indicates a normal weight; 700 indicates bold. Note: The specific interpretation of these values varies from font to font. For example, 300 in one font may appear most similar to 500 in another.

(Required) A collection of flags defining various characteristics of the font.

(Required, except for Type 3 fonts) A rectangle (see Section 3.8.4, “Rectangles”), expressed in the glyph coordinate system, specifying the font bounding box.

(Optional) The font’s x height: the vertical coordinate of the top of flat nonascending lowercase letters (like the letter x), measured from the baseline, in fonts that have Latin characters. Default value: 0.

(Required, except for Type 3 fonts) The thickness, measured horizontally, of the dominant vertical stems of glyphs in the font.

(Optional) The thickness, measured vertically, of the dominant horizontal stems of glyphs in the font. Default value: 0.

(Optional) The average width of glyphs in the font. Default value: 0.

(Optional) The maximum width of glyphs in the font. Default value: 0.

(Optional) The width to use for character codes whose widths are not specified in a font dictionary’s Widths array. This has a predictable effect only if all such codes map to glyphs whose actual widths are the same as the value of the MissingWidth entry. Default value: 0.

(Optional) A stream containing a Type 1 font program.

(Optional; PDF 1.1) A stream containing a TrueType font program.

(Optional; PDF 1.2) A stream containing a font program whose format is specified by the Subtype entry in the stream dictionary.

4 (32bpp RGB), 3 (24bpp RGB, 32bpp ARGB) 8 true (ARGB), false (RGB)

Common keys for all streams.

(Optional) The type of PDF object that this dictionary describes; if present, must be XObject for an image XObject.

(Required) The type of XObject that this dictionary describes; must be Image for an image XObject.

(Required) The width of the image, in samples.

(Required) The height of the image, in samples.

(Required for images, except those that use the JPXDecode filter; not allowed for image masks) The color space in which image samples are specified; it can be any type of color space except Pattern. If the image uses the JPXDecode filter, this entry is optional: • If ColorSpace is present, any color space specifications in the JPEG2000 data are ignored. • If ColorSpace is absent, the color space specifications in the JPEG2000 data are used. The Decode array is also ignored unless ImageMask is true.

(Required except for image masks and images that use the JPXDecode filter) The number of bits used to represent each color component. Only a single value may be specified; the number of bits is the same for all color components. Valid values are 1, 2, 4, 8, and (in PDF 1.5) 16. If ImageMask is true, this entry is optional, and if specified, its value must be 1. If the image stream uses a filter, the value of BitsPerComponent must be consistent with the size of the data samples that the filter delivers. In particular, a CCITTFaxDecode or JBIG2Decode filter always delivers 1-bit samples, a RunLengthDecode or DCTDecode filter delivers 8-bit samples, and an LZWDecode or FlateDecode filter delivers samples of a specified size if a predictor function is used. If the image stream uses the JPXDecode filter, this entry is optional and ignored if present. The bit depth is determined in the process of decoding the JPEG2000 image.

(Optional; PDF 1.1) The name of a color rendering intent to be used in rendering the image. Default value: the current rendering intent in the graphics state.

(Optional) A flag indicating whether the image is to be treated as an image mask. If this flag is true, the value of BitsPerComponent must be 1 and Mask and ColorSpace should not be specified; unmasked areas are painted using the current nonstroking color. Default value: false.

(Optional except for image masks; not allowed for image masks; PDF 1.3) An image XObject defining an image mask to be applied to this image, or an array specifying a range of colors to be applied to it as a color key mask. If ImageMask is true, this entry must not be present.

(Optional) An array of numbers describing how to map image samples into the range of values appropriate for the image’s color space. If ImageMask is true, the array must be either [0 1] or [1 0]; otherwise, its length must be twice the number of color components required by ColorSpace. If the image uses the JPXDecode filter and ImageMask is false, Decode is ignored. Default value: see “Decode Arrays”.

(Optional) A flag indicating whether image interpolation is to be performed. Default value: false.

(Optional; PDF 1.3) An array of alternate image dictionaries for this image. The order of elements within the array has no significance. This entry may not be present in an image XObject that is itself an alternate image.

(Optional; PDF 1.4) A subsidiary image XObject defining a soft-mask image to be used as a source of mask shape or mask opacity values in the transparent imaging model. The alpha source parameter in the graphics state determines whether the mask values are interpreted as shape or opacity. If present, this entry overrides the current soft mask in the graphics state, as well as the image’s Mask entry, if any. (However, the other transparency related graphics state parameters — blend mode and alpha constant — remain in effect.) If SMask is absent, the image has no associated soft mask (although the current soft mask in the graphics state may still apply).

(Optional for images that use the JPXDecode filter, meaningless otherwise; PDF 1.5) A code specifying how soft-mask information encoded with image samples should be used: 0 If present, encoded soft-mask image information should be ignored. 1 The image’s data stream includes encoded soft-mask values. An application can create a soft-mask image from the information to be used as a source of mask shape or mask opacity in the transparency imaging model. 2 The image’s data stream includes color channels that have been preblended with a background; the image data also includes an opacity channel. An application can create a soft-mask image with a Matte entry from the opacity channel information to be used as a source of mask shape or mask opacity in the transparency model. If this entry has a nonzero value, SMask should not be specified. Default value: 0.

(Required in PDF 1.0; optional otherwise) The name by which this image XObject is referenced in the XObject subdictionary of the current resource dictionary.

(Required if the image is a structural content item; PDF 1.3) The integer key of the image’s entry in the structural parent tree.

(Optional; PDF 1.3; indirect reference preferred) The digital identifier of the image’s parent Web Capture content set.

(Optional; PDF 1.2) An OPI version dictionary for the image. If ImageMask is true, this entry is ignored.

(Optional; PDF 1.4) A metadata stream containing metadata for the image.

(Optional; PDF 1.5) An optional content group or optional content membership dictionary, specifying the optional content properties for this image XObject. Before the image is processed, its visibility is determined based on this entry. If it is determined to be invisible, the entire image is skipped, as if there were no Do operator to invoke it.

Represents a shading dictionary.

Initializes a new instance of the class.

Setups the shading from the specified brush.

Common keys for all streams.

(Required) The shading type: 1 Function-based shading 2 Axial shading 3 Radial shading 4 Free-form Gouraud-shaded triangle mesh 5 Lattice-form Gouraud-shaded triangle mesh 6 Coons patch mesh 7 Tensor-product patch mesh

(Required) The color space in which color values are expressed. This may be any device, CIE-based, or special color space except a Pattern space.

(Optional) An array of color components appropriate to the color space, specifying a single background color value. If present, this color is used, before any painting operation involving the shading, to fill those portions of the area to be painted that lie outside the bounds of the shading object. In the opaque imaging model, the effect is as if the painting operation were performed twice: first with the background color and then with the shading.

(Optional) An array of four numbers giving the left, bottom, right, and top coordinates, respectively, of the shading’s bounding box. The coordinates are interpreted in the shading’s target coordinate space. If present, this bounding box is applied as a temporary clipping boundary when the shading is painted, in addition to the current clipping path and any other clipping boundaries in effect at that time.

(Optional) A flag indicating whether to filter the shading function to prevent aliasing artifacts. The shading operators sample shading functions at a rate determined by the resolution of the output device. Aliasing can occur if the function is not smooth—that is, if it has a high spatial frequency relative to the sampling rate. Anti-aliasing can be computationally expensive and is usually unnecessary, since most shading functions are smooth enough or are sampled at a high enough frequency to avoid aliasing effects. Anti-aliasing may not be implemented on some output devices, in which case this flag is ignored. Default value: false.

(Required) An array of four numbers [x0 y0 x1 y1] specifying the starting and ending coordinates of the axis, expressed in the shading’s target coordinate space.

(Optional) An array of two numbers [t0 t1] specifying the limiting values of a parametric variable t. The variable is considered to vary linearly between these two values as the color gradient varies between the starting and ending points of the axis. The variable t becomes the input argument to the color function(s). Default value: [0.0 1.0].

(Required) A 1-in, n-out function or an array of n 1-in, 1-out functions (where n is the number of color components in the shading dictionary’s color space). The function(s) are called with values of the parametric variable t in the domain defined by the Domain entry. Each function’s domain must be a superset of that of the shading dictionary. If the value returned by the function for a given color component is out of range, it is adjusted to the nearest valid value.

(Optional) An array of two boolean values specifying whether to extend the shading beyond the starting and ending points of the axis, respectively. Default value: [false false].

Represents a shading pattern dictionary.

Initializes a new instance of the class.

Setups the shading pattern from the specified brush.

Common keys for all streams.

(Optional) The type of PDF object that this dictionary describes; if present, must be Pattern for a pattern dictionary.

(Required) A code identifying the type of pattern that this dictionary describes; must be 2 for a shading pattern.

(Required) A shading object (see below) defining the shading pattern’s gradient fill.

(Optional) An array of six numbers specifying the pattern matrix. Default value: the identity matrix [1 0 0 1 0 0].

(Optional) A graphics state parameter dictionary containing graphics state parameters to be put into effect temporarily while the shading pattern is painted. Any parameters that are not so specified are inherited from the graphics state that was in effect at the beginning of the content stream in which the pattern is defined as a resource.

Represents a PDF soft mask.

Initializes a new instance of the class.

The document that owns the object.

Predefined keys of this dictionary.

(Optional) The type of PDF object that this dictionary describes; if present, must be Mask for a soft-mask dictionary.

(Required) A subtype specifying the method to be used in deriving the mask values from the transparency group specified by the G entry: Alpha: Use the group’s computed alpha, disregarding its color. Luminosity: Convert the group’s computed color to a single-component luminosity value.

(Required) A transparency group XObject to be used as the source of alpha or color values for deriving the mask. If the subtype S is Luminosity, the group attributes dictionary must contain a CS entry defining the color space in which the compositing computation is to be performed.

(Optional) An array of component values specifying the color to be used as the backdrop against which to composite the transparency group XObject G. This entry is consulted only if the subtype S is Luminosity. The array consists of n numbers, where n is the number of components in the color space specified by the CS entry in the group attributes dictionary. Default value: the color space’s initial value, representing black.

(Optional) A function object specifying the transfer function to be used in deriving the mask values. The function accepts one input, the computed group alpha or luminosity (depending on the value of the subtype S), and returns one output, the resulting mask value. Both the input and output must be in the range 0.0 to 1.0; if the computed output falls outside this range, it is forced to the nearest valid value. The name Identity may be specified in place of a function object to designate the identity function. Default value: Identity.

Represents a tiling pattern dictionary.

Initializes a new instance of the class.

Common keys for all streams.

(Optional) The type of PDF object that this dictionary describes; if present, must be Pattern for a pattern dictionary.

(Required) A code identifying the type of pattern that this dictionary describes; must be 1 for a tiling pattern.

(Required) A code that determines how the color of the pattern cell is to be specified: 1: Colored tiling pattern. The pattern’s content stream specifies the colors used to paint the pattern cell. When the content stream begins execution, the current color is the one that was initially in effect in the pattern’s parent content stream. 2: Uncolored tiling pattern. The pattern’s content stream does not specify any color information. Instead, the entire pattern cell is painted with a separately specified color each time the pattern is used. Essentially, the content stream describes a stencil through which the current color is to be poured. The content stream must not invoke operators that specify colors or other color-related parameters in the graphics state; otherwise, an error occurs. The content stream may paint an image mask, however, since it does not specify any color information.

(Required) A code that controls adjustments to the spacing of tiles relative to the device pixel grid: 1: Constant spacing. Pattern cells are spaced consistently—that is, by a multiple of a device pixel. To achieve this, the application may need to distort the pattern cell slightly by making small adjustments to XStep, YStep, and the transformation matrix. The amount of distortion does not exceed 1 device pixel. 2: No distortion. The pattern cell is not distorted, but the spacing between pattern cells may vary by as much as 1 device pixel, both horizontally and vertically, when the pattern is painted. This achieves the spacing requested by XStep and YStep on average but not necessarily for each individual pattern cell. 3: Constant spacing and faster tiling. Pattern cells are spaced consistently as in tiling type 1 but with additional distortion permitted to enable a more efficient implementation.

(Required) An array of four numbers in the pattern coordinate system giving the coordinates of the left, bottom, right, and top edges, respectively, of the pattern cell’s bounding box. These boundaries are used to clip the pattern cell.

(Required) The desired horizontal spacing between pattern cells, measured in the pattern coordinate system.

(Required) The desired vertical spacing between pattern cells, measured in the pattern coordinate system. Note that XStep and YStep may differ from the dimensions of the pattern cell implied by the BBox entry. This allows tiling with irregularly shaped figures. XStep and YStep may be either positive or negative but not zero.

(Required) A resource dictionary containing all of the named resources required by the pattern’s content stream (see Section 3.7.2, “Resource Dictionaries”).

(Optional) An array of six numbers specifying the pattern matrix. Default value: the identity matrix [1 0 0 1 0 0].

Equivalently, this value is 1 greater than the highest object number used in the file. Note: Any object in a cross-reference section whose number is greater than this value is ignored and considered missing.

Gets the KeysMeta for these keys.

Gets the KeysMeta of this dictionary type.

Represents a PDF transparency group XObject.

Predefined keys of this dictionary.

(Sometimes required, as discussed below) The group color space, which is used for the following purposes: • As the color space into which colors are converted when painted into the group • As the blending color space in which objects are composited within the group • As the color space of the group as a whole when it in turn is painted as an object onto its backdrop The group color space may be any device or CIE-based color space that treats its components as independent additive or subtractive values in the range 0.0 to 1.0, subject to the restrictions described in Section 7.2.3, “Blending Color Space.” These restrictions exclude Lab and lightness-chromaticity ICCBased color spaces, as well as the special color spaces Pattern, Indexed, Separation, and DeviceN. Device color spaces are subject to remapping according to the DefaultGray, DefaultRGB, and DefaultCMYK entries in the ColorSpace subdictionary of the current resource dictionary. Ordinarily, the CS entry is allowed only for isolated transparency groups (those for which I, below, is true), and even then it is optional. However, this entry is required in the group attributes dictionary for any transparency group XObject that has no parent group or page from which to inherit — in particular, one that is the value of the G entry in a soft-mask dictionary of subtype Luminosity. In addition, it is always permissible to specify CS in the group attributes dictionary associated with a page object, even if I is false or absent. In the normal case in which the page is imposed directly on the output medium, the page group is effectively isolated regardless of the I value, and the specified CS value is therefore honored. But if the page is in turn used as an element of some other page and if the group is non-isolated, CS is ignored and the color space is inherited from the actual backdrop with which the page is composited. Default value: the color space of the parent group or page into which this transparency group is painted. (The parent’s color space in turn can be either explicitly specified or inherited.)

(Optional) A flag specifying whether the transparency group is isolated. If this flag is true, objects within the group are composited against a fully transparent initial backdrop; if false, they are composited against the group’s backdrop. Default value: false. In the group attributes dictionary for a page, the interpretation of this entry is slightly altered. In the normal case in which the page is imposed directly on the output medium, the page group is effectively isolated and the specified I value is ignored. But if the page is in turn used as an element of some other page, it is treated as if it were a transparency group XObject; the I value is interpreted in the normal way to determine whether the page group is isolated.

(Optional) A flag specifying whether the transparency group is a knockout group. If this flag is false, later objects within the group are composited with earlier ones with which they overlap; if true, they are composited with the group’s initial backdrop and overwrite (“knock out”) any earlier overlapping objects. Default value: false.

Predefined keys of this dictionary.

(Required) The type of PDF object that this dictionary describes; must be Font for a font dictionary.

(Required) The type of font; must be TrueType for a TrueType font.

(Required in PDF 1.0; optional otherwise) The name by which this font is referenced in the Font subdictionary of the current resource dictionary.

(Required) The PostScript name of the font. For Type 1 fonts, this is usually the value of the FontName entry in the font program; for more information. The Post-Script name of the font can be used to find the font’s definition in the consumer application or its environment. It is also the name that is used when printing to a PostScript output device.

(Required except for the standard 14 fonts) The first character code defined in the font’s Widths array.

(Required except for the standard 14 fonts) The last character code defined in the font’s Widths array.

(Required except for the standard 14 fonts; indirect reference preferred) An array of (LastChar - FirstChar + 1) widths, each element being the glyph width for the character code that equals FirstChar plus the array index. For character codes outside the range FirstChar to LastChar, the value of MissingWidth from the FontDescriptor entry for this font is used. The glyph widths are measured in units in which 1000 units corresponds to 1 unit in text space. These widths must be consistent with the actual widths given in the font program.

(Optional) A specification of the font’s character encoding if different from its built-in encoding. The value of Encoding is either the name of a predefined encoding (MacRomanEncoding, MacExpertEncoding, or WinAnsiEncoding, as described in Appendix D) or an encoding dictionary that specifies differences from the font’s built-in encoding or from a specified predefined encoding.

(Optional; PDF 1.2) A stream containing a CMap file that maps character codes to Unicode values.

Predefined keys of this dictionary.

(Required) The type of PDF object that this dictionary describes; must be Font for a font dictionary.

(Required) The type of font; must be Type0 for a Type 0 font.

(Required) The PostScript name of the font. In principle, this is an arbitrary name, since there is no font program associated directly with a Type 0 font dictionary. The conventions described here ensure maximum compatibility with existing Acrobat products. If the descendant is a Type 0 CIDFont, this name should be the concatenation of the CIDFont’s BaseFont name, a hyphen, and the CMap name given in the Encoding entry (or the CMapName entry in the CMap). If the descendant is a Type 2 CIDFont, this name should be the same as the CIDFont’s BaseFont name.

(Required) The name of a predefined CMap, or a stream containing a CMap that maps character codes to font numbers and CIDs. If the descendant is a Type 2 CIDFont whose associated TrueType font program is not embedded in the PDF file, the Encoding entry must be a predefined CMap name.

(Required) A one-element array specifying the CIDFont dictionary that is the descendant of this Type 0 font.

Specifies the annotation flags.

If set, do not display the annotation if it does not belong to one of the standard annotation types and no annotation handler is available. If clear, display such an unknown annotation using an appearance stream specified by its appearancedictionary, if any.

(PDF 1.2) If set, do not display or print the annotation or allow it to interact with the user, regardless of its annotation type or whether an annotation handler is available. In cases where screen space is limited, the ability to hide and show annotations selectively can be used in combination with appearance streams to display auxiliary pop-up information similar in function to online help systems.

(PDF 1.2) If set, print the annotation when the page is printed. If clear, never print the annotation, regardless of whether it is displayed on the screen. This can be useful, for example, for annotations representing interactive pushbuttons, which would serve no meaningful purpose on the printed page.

(PDF 1.3) If set, do not scale the annotation’s appearance to match the magnification of the page. The location of the annotation on the page (defined by the upper-left corner of its annotation rectangle) remains fixed, regardless of the page magnification. See below for further discussion.

(PDF 1.3) If set, do not rotate the annotation’s appearance to match the rotation of the page. The upper-left corner of the annotation rectangle remains in a fixed location on the page, regardless of the page rotation. See below for further discussion.

(PDF 1.3) If set, do not display the annotation on the screen or allow it to interact with the user. The annotation may be printed (depending on the setting of the Print flag) but should be considered hidden for purposes of on-screen display and user interaction.

(PDF 1.3) If set, do not allow the annotation to interact with the user. The annotation may be displayed or printed (depending on the settings of the NoView and Print flags) but should not respond to mouse clicks or change its appearance in response to mouse motions. Note: This flag is ignored for widget annotations; its function is subsumed by the ReadOnly flag of the associated form field.

(PDF 1.4) If set, do not allow the annotation to be deleted or its properties (including position and size) to be modified by the user. However, this flag does not restrict changes to the annotation’s contents, such as the value of a form field.

(PDF 1.5) If set, invert the interpretation of the NoView flag for certain events. A typical use is to have an annotation that appears only when a mouse cursor is held over it.

(Optional) The type of PDF object that this dictionary describes; if present, must be Annot for an annotation dictionary.

(Required) The type of annotation that this dictionary describes.

(Required) The annotation rectangle, defining the location of the annotation on the page in default user space units.

(Optional) Text to be displayed for the annotation or, if this type of annotation does not display text, an alternate description of the annotation’s contents in human-readable form. In either case, this text is useful when extracting the document’s contents in support of accessibility to users with disabilities or for other purposes.

(Optional; PDF 1.4) The annotation name, a text string uniquely identifying it among all the annotations on its page.

(Optional; PDF 1.1) The date and time when the annotation was most recently modified. The preferred format is a date string, but viewer applications should be prepared to accept and display a string in any format.

(Optional; PDF 1.1) A set of flags specifying various characteristics of the annotation. Default value: 0.

(Optional; PDF 1.2) A border style dictionary specifying the characteristics of the annotation’s border.

(Optional; PDF 1.2) An appearance dictionary specifying how the annotation is presented visually on the page. Individual annotation handlers may ignore this entry and provide their own appearances.

(Required if the appearance dictionary AP contains one or more subdictionaries; PDF 1.2) The annotation’s appearance state, which selects the applicable appearance stream from an appearance subdictionary.

(Optional) An array specifying the characteristics of the annotation’s border. The border is specified as a rounded rectangle. In PDF 1.0, the array consists of three numbers defining the horizontal corner radius, vertical corner radius, and border width, all in default user space units. If the corner radii are 0, the border has square (not rounded) corners; if the border width is 0, no border is drawn. In PDF 1.1, the array may have a fourth element, an optional dash array defining a pattern of dashes and gaps to be used in drawing the border. The dash array is specified in the same format as in the line dash pattern parameter of the graphics state. For example, a Border value of [0 0 1 [3 2]] specifies a border 1 unit wide, with square corners, drawn with 3-unit dashes alternating with 2-unit gaps. Note that no dash phase is specified; the phase is assumed to be 0. Note: In PDF 1.2 or later, this entry may be ignored in favor of the BS entry.

(Optional; PDF 1.1) An array of three numbers in the range 0.0 to 1.0, representing the components of a color in the DeviceRGB color space. This color is used for the following purposes: • The background of the annotation’s icon when closed • The title bar of the annotation’s pop-up window • The border of a link annotation

(Required if the annotation is a structural content item; PDF 1.3) The integer key of the annotation’s entry in the structural parent tree.

(Optional; PDF 1.1) An action to be performed when the annotation is activated. Note: This entry is not permitted in link annotations if a Dest entry is present. Also note that the A entry in movie annotations has a different meaning.

(Optional; PDF 1.1) The text label to be displayed in the title bar of the annotation’s pop-up window when open and active. By convention, this entry identifies the user who added the annotation.

(Optional; PDF 1.3) An indirect reference to a pop-up annotation for entering or editing the text associated with this annotation.

(Optional; PDF 1.4) The constant opacity value to be used in painting the annotation. This value applies to all visible elements of the annotation in its closed state (including its background and border) but not to the popup window that appears when the annotation is opened. The specified value is not used if the annotation has an appearance stream; in that case, the appearance stream must specify any transparency. (However, if the viewer regenerates the annotation’s appearance stream, it may incorporate the CA value into the stream’s content.) The implicit blend mode is Normal. Default value: 1.0.

(Optional; PDF 1.5) Text representing a short description of the subject being addressed by the annotation.

I (Invert) Invert the contents of the annotation rectangle. O (Outline) Invert the annotation’s border. P (Push) Display the annotation as if it were being pushed below the surface of the page. Default value: I. Note: In PDF 1.1, highlighting is always done by inverting colors inside the annotation rectangle.

(Optional; PDF 1.3) A URI action formerly associated with this annotation. When Web Capture changes and annotation from a URI to a go-to action, it uses this entry to save the data from the original URI action so that it can be changed back in case the target page for the go-to action is subsequently deleted.

Common keys for all streams.

(Required) The number of bytes from the beginning of the line following the keyword stream to the last byte just before the keyword endstream. (There may be an additional EOL marker, preceding endstream, that is not included in the count and is not logically part of the stream data.)

(Optional) The name of a filter to be applied in processing the stream data found between the keywords stream and endstream, or an array of such names. Multiple filters should be specified in the order in which they are to be applied.

(Optional) A parameter dictionary or an array of such dictionaries, used by the filters specified by Filter. If there is only one filter and that filter has parameters, DecodeParms must be set to the filter’s parameter dictionary unless all the filter’s parameters have their default values, in which case the DecodeParms entry may be omitted. If there are multiple filters and any of the filters has parameters set to nondefault values, DecodeParms must be an array with one entry for each filter: either the parameter dictionary for that filter, or the null object if that filter has no parameters (or if all of its parameters have their default values). If none of the filters have parameters, or if all their parameters have default values, the DecodeParms entry may be omitted.

(Optional; PDF 1.2) The file containing the stream data. If this entry is present, the bytes between stream and endstream are ignored, the filters are specified by FFilter rather than Filter, and the filter parameters are specified by FDecodeParms rather than DecodeParms. However, the Length entry should still specify the number of those bytes. (Usually, there are no bytes and Length is 0.)

(Optional; PDF 1.2) The name of a filter to be applied in processing the data found in the stream’s external file, or an array of such names. The same rules apply as for Filter.

(Optional; PDF 1.2) A parameter dictionary, or an array of such dictionaries, used by the filters specified by FFilter. The same rules apply as for DecodeParms.

Optional; PDF 1.5) A non-negative integer representing the number of bytes in the decoded (defiltered) stream. It can be used to determine, for example, whether enough disk space is available to write a stream to a file. This value should be considered a hint only; for some stream filters, it may not be possible to determine this value precisely.

Gets the DebuggerDisplayAttribute text.

This allows PDF producers to create image objects and other resources as they occur, even though they interrupt the content stream. The division between streams may occur only at the boundaries between lexical tokens but is unrelated to the page’s logical content or organization. Applications that consume or produce PDF files are not required to preserve the existing structure of the Contents array.

(Optional; PDF 1.1) A transition dictionary describing the transition effect to be used when displaying the page during presentations.

(Optional) An array of annotation dictionaries representing annotations associated with the page.

(Optional; PDF 1.2) An additional-actions dictionary defining actions to be performed when the page is opened or closed.

(Optional; PDF 1.3) A separation dictionary containing information needed to generate color separations for the page.

(Optional; PDF 1.5) A name specifying the tab order to be used for annotations on the page. The possible values are R (row order), C (column order), and S (structure order).

Computes Adler32 checksum for a stream of data. An Adler32 checksum is not as reliable as a CRC32 checksum, but a lot faster to compute. The specification for Adler32 may be found in RFC 1950. ZLIB Compressed Data Format Specification version 3.3) From that document: "ADLER32 (Adler-32 checksum) This contains a checksum value of the uncompressed data (excluding any dictionary data) computed according to Adler-32 algorithm. This algorithm is a 32-bit extension and improvement of the Fletcher algorithm, used in the ITU-T X.224 / ISO 8073 standard. Adler-32 is composed of two sums accumulated per byte: s1 is the sum of all bytes, s2 is the sum of all s1 values. Both sums are done modulo 65521. s1 is initialized to 1, s2 to zero. The Adler-32 checksum is stored as s2*65536 + s1 in most- significant-byte first (network) order." "8.2. The Adler-32 algorithm The Adler-32 algorithm is much faster than the CRC32 algorithm yet still provides an extremely low probability of undetected errors. The modulo on unsigned long accumulators can be delayed for 5552 bytes, so the modulo operation time is negligible. If the bytes are a, b, c, the second sum is 3a + 2b + c + 3, and so is position and order sensitive, unlike the first sum, which is just a checksum. That 65521 is prime is important to avoid a possible large class of two-byte errors that leave the check unchanged. (The Fletcher checksum uses 255, which is not prime and which also makes the Fletcher check insensitive to single byte changes 0 - 255.) The sum s1 is initialized to 1 instead of zero to make the length of the sequence part of s2, so that the length does not have to be checked separately. (Any sequence of zeroes has a Fletcher checksum of zero.)"

Generate a table for a byte-wise 32-bit CRC calculation on the polynomial: x^32+x^26+x^23+x^22+x^16+x^12+x^11+x^10+x^8+x^7+x^5+x^4+x^2+x+1. Polynomials over GF(2) are represented in binary, one bit per coefficient, with the lowest powers in the most significant bit. Then adding polynomials is just exclusive-or, and multiplying a polynomial by x is a right shift by one. If we call the above polynomial p, and represent a byte as the polynomial q, also with the lowest power in the most significant bit (so the byte 0xb1 is the polynomial x^7+x^3+x+1), then the CRC is (q*x^32) mod p, where a mod b means the remainder after dividing a by b. This calculation is done using the shift-register method of multiplying and taking the remainder. The register is initialized to zero, and for each incoming bit, x^32 is added mod p to the register if the bit is a one (where x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by x (which is shifting right by one and adding x^32 mod p if the bit shifted out is a one). We start with the highest power (least significant bit) of q and repeat for all eight bits of q. The table is simply the CRC of all possible eight bit values. This is all the information needed to generate CRC's on data a byte at a time for all combinations of CRC register values and incoming bytes.

This is the Deflater class. The deflater class compresses input with the deflate algorithm described in RFC 1951. It has several compression levels and three different strategies described below. This class is not thread safe. This is inherent in the API, due to the split of deflate and setInput. Author of the original java version: Jochen Hoenicke

The best and slowest compression level. This tries to find very long and distant string repetitions.

The worst but fastest compression level.

The default compression level.

This level won't compress at all but output uncompressed blocks.

The compression method. This is the only method supported so far. There is no need to use this constant at all.

Creates a new deflater with default compression level.

Creates a new deflater with given compression level.

the compression level, a value between NO_COMPRESSION and BEST_COMPRESSION, or DEFAULT_COMPRESSION. if lvl is out of range.

Creates a new deflater with given compression level.

the compression level, a value between NO_COMPRESSION and BEST_COMPRESSION. true, if we should suppress the Zlib/RFC1950 header at the beginning and the adler checksum at the end of the output. This is useful for the GZIP/PKZIP formats. if lvl is out of range.

Resets the deflater. The deflater acts afterwards as if it was just created with the same compression level and strategy as it had before.

Gets the current adler checksum of the data that was processed so far.

Gets the number of input bytes processed so far.

Gets the number of output bytes so far.

Flushes the current input block. Further calls to deflate() will produce enough output to inflate everything in the current input block. This is not part of Sun's JDK so I have made it package private. It is used by DeflaterOutputStream to implement flush().

Finishes the deflater with the current input block. It is an error to give more input after this method was called. This method must be called to force all bytes to be flushed.

Returns true if the stream was finished and no more output bytes are available.

Returns true, if the input buffer is empty. You should then call setInput(). NOTE: This method can also return true when the stream was finished.

Sets the data which should be compressed next. This should be only called when needsInput indicates that more input is needed. If you call setInput when needsInput() returns false, the previous input that is still pending will be thrown away. The given byte array should not be changed, before needsInput() returns true again. This call is equivalent to setInput(input, 0, input.length).

Sets the data which should be compressed next. This should be only called when needsInput indicates that more input is needed. The given byte array should not be changed, before needsInput() returns true again.

the buffer containing the input data. the start of the data. the number of data bytes of input. if the buffer was Finish()ed or if previous input is still pending.

Sets the compression level. There is no guarantee of the exact position of the change, but if you call this when needsInput is true the change of compression level will occur somewhere near before the end of the so far given input.

Get current compression level

Returns the current compression level

Sets the compression strategy. Strategy is one of DEFAULT_STRATEGY, HUFFMAN_ONLY and FILTERED. For the exact position where the strategy is changed, the same as for SetLevel() applies.

If offset or length don't match the array length.

Sets the dictionary which should be used in the deflate process. This call is equivalent to setDictionary(dict, 0, dict.Length).

the dictionary. if SetInput () or Deflate () were already called or another dictionary was already set.

Sets the dictionary which should be used in the deflate process. The dictionary is a byte array containing strings that are likely to occur in the data which should be compressed. The dictionary is not stored in the compressed output, only a checksum. To decompress the output you need to supply the same dictionary again.

Hashtable, hashing three characters to an index for window, so that window[index]..window[index+2] have this hash code. Note that the array should really be unsigned short, so you need to and the values with 0xffff.

prev[index & WMASK] points to the previous index that has the same hash code as the string starting at index. This way entries with the same hash code are in a linked list. Note that the array should really be unsigned short, so you need to and the values with 0xffff.

Points to the current character in the window.

lookahead is the number of characters starting at strstart in window that are valid. So window[strstart] until window[strstart+lookahead-1] are valid characters.

This class stores the pending output of the Deflater. Author of the original java version: Jochen Hoenicke

Construct instance with default buffer size

Inflater is used to decompress data that has been compressed according to the "deflate" standard described in rfc1951. By default Zlib (rfc1950) headers and footers are expected in the input. You can use constructor public Inflater(bool noHeader) passing true if there is no Zlib header information The usage is as following. First you have to set some input with SetInput(), then Inflate() it. If inflate doesn't inflate any bytes there may be three reasons:

IsNeedingInput() returns true because the input buffer is empty. You have to provide more input with SetInput(). NOTE: IsNeedingInput() also returns true when, the stream is finished.
IsNeedingDictionary() returns true, you have to provide a preset dictionary with SetDictionary().
IsFinished returns true, the inflater has finished.

Once the first output byte is produced, a dictionary will not be needed at a later stage. Author of the original java version: John Leuner, Jochen Hoenicke

This class allows us to retrieve a specified number of bits from the input buffer, as well as copy big byte blocks. It uses an int buffer to store up to 31 bits for direct manipulation. This guarantees that we can get at least 16 bits, but we only need at most 15, so this is all safe. There are some optimizations in this class, for example, you must never peek more than 8 bits more than needed, and you must first peek bits before you may drop them. This is not a general purpose class but optimized for the behaviour of the Inflater. Authors of the original java version: John Leuner, Jochen Hoenicke
