WinBitmapSize Function (ROM Call 0x8)

wingraph.h

unsigned short WinBitmapSize (WINDOW *w, const WIN_RECT *rect);

Determines a size of a bitmap (eventually clipped) in bytes.

WinBitmapSize returns the size in bytes of a bitmap for a part of rectangular area given by parameter rect which belongs to the window pointed to by w (may be smaller than the size of this area due to clipping). This size includes the data for the bitmap and the header. All coordinates in rect are relative to the topleft corner of the window. See WinBitmapGet for more info about bitmaps.

Note: WinBitmapSize will clip any negative coordinates to zero.
