CreateDiscardableBitmap info  Overview  Group

The CreateDiscardableBitmap function creates a discardable bitmap that is compatible with the specified device. The bitmap has the same bits-per-pixel format and the same color palette as the device. An application can select this bitmap as the current bitmap for a memory device that is compatible with the specified device.

The CreateDiscardableBitmap function is included only for compatibility with earlier versions of Windows. For Win32-based applications, use the CreateCompatibleBitmap function.

HBITMAP CreateDiscardableBitmap(

HDC hdc,	// handle to device context
int nWidth,	// bitmap width
int nHeight	// bitmap height
);

Parameters

hdc

Identifies a device context.

nWidth

Specifies the width, in bits, of the bitmap.

nHeight

Specifies the height, in bits, of the bitmap.

Return Values

If the function succeeds, the return value is a handle to the bitmap.

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

Remarks

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