Constants and Data Types for the Raster Imaging System

Raster Render Options

The raster render options enumeration defines constants that you can use in the renderOptions field of the raster imaging system structure, which is described in the previous section.

enum {
   gxDefaultRaster               = 0x00000000,
   gxDontResolveTransferModes    = 0x00000001,
   gxRenderInReverse             = 0x00000002,
   gxOnePlaneAtATime             = 0x00000004,
   gxSendAllBands                = 0x00000008
};
typedef long gxRasterRenderOptions;

Constant descriptions

gxDefaultRaster

The driver uses the default raster options.

gxDontResolveTransferModes

If this is included, the driver does not need to resolve transfer modes. The default is to resolve transfer modes.

gxRenderInReverse

The driver needs to traverse the raster image in reverse order.

gxOnePlaneAtATime

The driver needs to render each plane separately.

gxSendAllBands

The driver needs to send every band of data, even if it is all empty.
