Color Resolution Flag Values
Processing options. Note that the palette and dithering options are useful only when the resulting bitmap requires a palette (when it is 8 bits per pixel or less). You can combine values when appropriate by using a bitwise OR ( | ). The following are valid values:
Value |
Meaning |
CRF_FIXEDPALETTE |
[0x01] Use the fixed palette. |
CRF_OPTIMIZEDPALETTE |
[0x02] Create an optimized palette. |
CRF_BYTEORDERBGR |
[0x04] Use BGR color order. This flag only has meaning when going to 16 bits per pixel or higher. |
CRF_BYTEORDERRGB |
[0x00] Use RGB color order. This flag only has meaning when going to 16 bits per pixel or higher. |
CRF_IDENTITYPALETTE |
[0x08] Insert the Windows system palette. |
CRF_USERPALETTE |
[0x10] Use the palette specified in the pPalette parameter. |
CRF_FASTMATCHPALETTE |
[0x20] Use a predefined table to speed conversion using your own palette. Refer to L_CreateUserMatchTable |
CRF_NODITHERING |
[0x00000000] Use nearest color matching. |
CRF_FLOYDSTEINDITHERING |
[0x00010000] Use Floyd Stein dithering. |
CRF_STUCKIDITHERING |
[0x00020000] Use Stucki dithering. |
CRF_BURKESDITHERING |
[0x00030000] Use Burkes dithering. |
CRF_SIERRADITHERING |
[0x00040000] Use Sierra dithering. |
CRF_STEVENSONARCEDITHERING |
[0x00050000] Use Stevenson Arce dithering. |
CRF_JARVISDITHERING |
[0x00060000] Use Jarvis dithering. |
CRF_ORDEREDDITHERING |
[0x00070000] Use ordered dithering, which is faster but less accurate than other dithering methods. |
