Color Resolution Flag Values (original) (raw)
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. |
