I'm trying to capture video. In the capture the user can select a specific area
to capture out of the full field of the video.
That much functions the problem is that although the image I get has the
correct size I cannot figure out how to get that source image to draw in to an
NSImage correctly
Ok am I barking up the wrong tree here?
I know there has to be a way of taking an image of size say 128X128
and drawing it in to a rectangle of say size 256X512
without loosing the aspect ratio of the original image.
However The following code DOES NOT DO THIS
NSImage * screenImage = [[NSImage a
-drawInRect draws the image into the destination rectangle, stretching or
shrinking as necessary to get it to fit. If you want to preserve the aspect
ratio, you'll have to generate a scaled rectangle with the image's aspect
ratio. That's just simple math.

Yes, completely mistaken.
It may help to think of the source and destination rectangle as an origin and a
size separately.
The source re
After doing the ratio copy, you then need to decide what to do with rest of the
destination image. Probably set it to a specific colour.
