Constants and Data Types for the Raster Imaging System

Raster Offscreen Plane Setup Structure

The raster offscreen plane setup structure, of data type gxPlaneSetupRec, defines settings for storing a single plane of raster data in offscreen memory. The raster offscreen setup structure, described in the previous section, uses four of these structures.

struct gxPlaneSetupRec {
   gxRasterPlaneOptions    planeOptions;
   gxHalftone              planeHalftone;
   gxColorSpace            planeSpace;
   gxColorSet              planeSet;
   gxColorProfile          planeProfile;
};
typedef struct gxPlaneSetupRec gxPlaneSetupRec;

Field Description

planeOptions

The options for this plane. This value is the combined values of the constants that you include from the raster plane options enumeration, which is described in the next section.

planeHalftone

The halftone structure for this plane. This is optional.

planeSpace

The color space for this plane. The color-space value constants are shown in the chapter "Colors and Color-Related Objects" in Inside Macintosh: QuickDraw GX Objects. You can specify the value gxNoSpace to use the default color space.

planeSet

The color set for this plane. You can specify nil to use the default color set.

planeProfile

The color profile for this plane. You can specify nil if you do not want color matching applied to this plane.
