HBITMAP CreateDiscardableBitmap(hDC, nWidth, nHeight) | |||||
HDC hDC; | /* handle of device context | */ | |||
int nWidth; | /* bitmap width | */ | |||
int nHeight; | /* bitmap height | */ |
The CreateDiscardableBitmap function creates a discardable bitmap that is compatible with the device identified by the hDC parameter. The bitmap has the same bits-per-pixel format and the same color palette as the specified device. An application can select this bitmap as the current bitmap for a memory device that is compatible with the one specified by the hDC parameter.
hDC
Identifies a device context.
nWidth
Specifies the width (in bits) of the bitmap.
nHeight
Specifies the height (in bits) of the bitmap.
The return value identifies a bitmap if the function is successful. Otherwise, it is NULL.
Under Win32 this function is the same as CreateCompatibleBitmap and is included only for compatibility purposes.
