Copies the bit pattern of the CBitmap object into the buffer that is pointed to by lpBits.
DWORD GetBitmapBits(
DWORD dwCount,
LPVOID lpBits
) const;
Parameters
dwCount
Specifies the number of bytes to be copied.lpBits
Points to the buffer that is to receive the bitmap. The bitmap is an array of bytes. The bitmap byte array conforms to a structure where horizontal scan lines are multiples of 16 bits.
Return Value
The actual number of bytes in the bitmap, or 0 if there is an error.
Remarks
The dwCount parameter specifies the number of bytes to be copied to the buffer. Use CGdiObject::GetObject to determine the correct dwCount value for the given bitmap.
