The ResizePalette function increases or decreases the size of a logical palette based on the specified value.
BOOL ResizePalette(
HPALETTE hpal, |
// handle of logical palette |
UINT nEntries |
// number of entries in logical palette |
); |
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
An application can determine whether a device supports palette operations by calling the GetDeviceCaps function and specifying the RASTERCAPS constant.
If an application calls ResizePalette to reduce the size of the palette, the entries remaining in the resized palette are unchanged. If the application calls ResizePalette to enlarge the palette, the additional palette entries are set to black (the red, green, and blue values are all 0) and their flags are set to zero.
