window size VS. pixel size

anybody know how to work out how big to make a window based on the size of an image in pixels?

i thought that if you set a windows size to be, say, 200x200, and then displayed a 200x200 pixel image, the image would fill the window perfectly... unfortunately this doesn't seem to be the case... is there a way to calculate how big to make a window based on the number of pixels in an image?

cheers chaps.

AdjustWindowRect() is what you are looking for. Also, check out this thread.

yup, that's the one, very good method in that thread.

thank you.
