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
Identifies
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. 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.
