Getting the size of a bitmap
You can use GetDeviceCaps() to get:
HORZSIZE Width, in millimeters, of the physical screen.
VERTSIZE Height, in millimeters, of the physical screen.
HORZRES Width, in pixels, of the screen.
VERTRES Height, in raster lines, of the screen.
This info, along with the x and y resolution of the bitmap, should get you
what you need.
Hope this helps,
Mike.
