ResizePalette

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
);
 

Parameters

hpal

Handle to the palette to be changed.

nEntries

Specifies the number of entries in the palette after it has been resized.

Return Values

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero.

Windows NT: To get extended error information, call GetLastError.

Remarks

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.
