CreateHalftonePalette

The CreateHalftonePalette function creates a halftone palette for the specified device context.

HPALETTE CreateHalftonePalette(

HDC hdc	// handle to device context
);

Parameters

hdc

Identifies the device context.

Return Values

If the function succeeds, the return value identifies a logical halftone palette.

If the function fails, the return value is zero. To get extended error information, call GetLastError.

Remarks

An application should create a halftone palette when the stretching mode of a device context is set to HALFTONE. The logical halftone palette returned by CreateHalftonePalette should then be selected and realized into the device context before the StretchBlt or StretchDIBits function is called.

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