Constants and Data Types for the PostScript Imaging System

PostScript Render Options

The PostScript render options enumeration defines constants for use in the renderOptions field of the PostScript imaging system structure, which is described in the previous section.

enum 
{
   gxNeedsAsciiOption            = 0x00000001,
   gxNeedsCommentsOption         = 0x00000002,
   gxBoundingBoxesOption         = 0x00000004,
   gxPortablePostScriptOption    = 0x00000008,
   gxUseLevel2ColorOption        = 0x00000080
};
typedef long gxPostScriptRenderOptions;

Constant descriptions

gxNeedsAsciiOption

The driver needs to convert all binary data to 7-bit ASCII values.

gxNeedsCommentsOption

The driver needs to issue PostScript comments.

gxBoundingBoxesOption

The driver needs to calculate values for the %%BoundingBox: and %%PageBoundingBox: variables. This option implies the gxNeedsCommentsOption constant.

gxUseLevel2ColorOption

The driver uses Level 2 device-independent color when printing to a Level 2 output device.
