CreatePalette

The CreatePalette function creates a logical color palette.

HPALETTE CreatePalette(
  CONST LOGPALETTE *lplgpl   // pointer to logical color palette
);
 

Parameters

lplgpl
Pointer to a LOGPALETTE structure that contains information about the colors in the logical palette.

Return Values

If the function succeeds, the return value is a handle that identifies a logical palette.

If the function fails, the return value is NULL.

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.

Once an application creates a logical palette, it can select that palette into a device context by calling the SelectPalette function. A palette selected into a device context can be realized by calling the RealizePalette function.

When you no longer need the palette, call the DeleteObject function to delete it.

Windows CE: Since Windows CE does not arbitrate between the palettes of the foreground and background applications, palettes are not automatically padded with Windows systems colors. Therefore, the number of color entries in the palette created by this function is always the same as the palNumEntries member of the LOGPALETTE structure.
