2.1.1.6 ColorUsage Enumeration

  • Article

The ColorUsage Enumeration specifies whether a color table exists in a device-independent bitmap (DIB) and how to interpret its values.

 typedef  enum
 {
   DIB_RGB_COLORS = 0x0000,
   DIB_PAL_COLORS = 0x0001,
   DIB_PAL_INDICES = 0x0002
 } ColorUsage;

DIB_RGB_COLORS: The color table contains RGB values specified by RGBQuad Objects (section 2.2.2.20).

DIB_PAL_COLORS: The color table contains 16-bit indices into the current logical palette in the playback device context.

DIB_PAL_INDICES: No color table exists. The pixels in the DIB are indices into the current logical palette in the playback device context.

A DIB is specified by a DeviceIndependentBitmap Object (section 2.2.2.9).
