PDF Component Structures Reference

In This Topic

This section provides information about simple structure types that are used for creating, attributing, and manipulating general and editing objects.

The following table describes the structures supported by the ImageGear PDF component:

Subsidiary Type / DLL Structure	Description
AT_PDE_COLORDATA	Fill in one of the following members of this union, then pass it to PDE ColorSpace creation routine. Please see section 7.10 of the PDF Reference Manual for information on color spaces.
AT_PDE_COLORDATA_CALGRAY	CalGray color space.
AT_PDE_COLORDATA_CALRGB	CalRGB color space.
AT_PDE_COLORDATA_DEVICEN	DeviceN color space.
AT_PDE_COLORDATA_ICCBASED	ICC based color space.
AT_PDE_COLORDATA_INDEXED	Indexed color space.
AT_PDE_COLORDATA_LAB	Lab* color space.
AT_PDE_COLORDATA_SEPARATION	Separation color space
AT_PDE_COLORRANGE	Color range.
AT_PDE_COLORSPEC	Color specification.
AT_PDE_COLORVALUE	Color value.
AT_PDE_CONTENTATTRS	Attributes of a PDE Content object.
AT_PDE_DASH	Dash specification, as described in Table 4.8 in the PDF Reference. See Section 4.3.2 for more information on line dash patterns.
AT_PDE_FILTERARRAY	Filter information for streams. Array of FilterSpec elements. Usually consists of 2 filter elements: text encoding and image compression.
AT_PDE_FILTERSPEC	Filter element in a filter array.
AT_PDE_FONT_CREATEFROMSYSFONTPARAMS	Parameters for PDE font creation.
AT_PDE_FONT_INFO	PDE Font information.
AT_PDE_FONTATTRS	Attributes of a PDE Font and a PDF SysFont.
AT_PDE_GRAPHICSTATE	Attributes of a PDE Element or a PDE Text sub-element.
AT_PDE_IMAGEATTRS	Attributes of a PDE Image object.
AT_PDE_PSATTRS	Attributes of a PDE PS object.
AT_PDE_TEXTSTATE	Attributes of a PDE Text element.
AT_PDE_XYZCOLOR	XYZ color.
AT_PDF_BOOL	Boolean type with two values: TRUE (1) or FALSE (0).
AT_PDF_COLORVALUE	Data structure representing a color.
AT_PDF_FIXED	The Fixed type is a 32-bit quantity representing a rational number with the high (low on little-endian machines) 16 bits representing the number's mantissa and the low (high) 16 bits representing the fractional part.
AT_PDF_FIXEDMATRIX	Matrix containing fixed numbers.
AT_PDF_FIXEDPOINT	Point (in two-dimensional space) represented by two fixed numbers.
AT_PDF_FIXEDQUAD	Quadrilateral represented by four fixed points (one at each corner). A quadrilateral differs from a rectangle in that the latter must always have horizontal and vertical sides, and opposite sides must be parallel.
AT_PDF_FIXEDRECT	A rectangle represented by the coordinates of its four sides. A rectangle differs from a quadrilateral in that the former must always have horizontal and vertical sides, and opposite sides must be parallel.
AT_PDF_FLATTEN	Controls tile flattening.
AT_PDF_FONT_METRICS	Font metrics.
AT_PDF_FONT_STYLES	Font styles.
AT_PDF_PRINTOPTIONS	This structure is used to provide printing parameters for the IG_PDF_doc_print function.
AT_PDF_PRINTPARAMS	This structure indicates how a document should be printed.
AT_PDF_SECURITYDATA	Describes the data for the standard security handler.
AT_PDF_SYSFONT_PLATDATA	PDF SysFont platform specific data.
AT_PDF_TILE	Specifies printing flags.
AT_PDF_TILEEX	Specifies printing flags.
