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).
