CBitmap::GetBitmapBits

Syntax

DWORD GetBitmapBits( DWORD dwCount, LPSTR 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.

Remarks

Copies the bit pattern of the CBitmap object into the buffer that is pointed to by lpBits. The dwCount parameter specifies the number of bytes to be copied to the buffer. Use GetObject to determine the correct dwCount value for the given bitmap.

Return Value

The actual number of bytes in the bitmap, or 0 if there is an error.
