The SetPaletteEntries function sets RGB (red, green, blue) color values and flags in a range of entries in a logical palette.
UINT SetPaletteEntries(
HPALETTE hpal, |
// handle of logical palette |
UINT iStart, |
// index of first entry to set |
UINT cEntries, |
// number of entries to set |
CONST PALETTEENTRY *lppe |
// address of array of structures |
); |
If the function succeeds, the return value is the number of entries that were set in the logical palette.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
An application can determine whether or not a device supports palette operations by calling the GetDeviceCaps function and specifying the RASTERCAPS constant.
Even if a logical palette has been selected and realized, changes to the palette do not affect the physical palette in the surface. RealizePalette must be called again to set the new logical palette into the surface.
