Larger sprite into smaller area (width, height)

BlitzMax Forums/BlitzMax Programming/Larger sprite into smaller area (width, height)

This should be pretty simple but for some reason its just not having it.

I have some images that are larger than my "image preview" area and I need them to be scaled down to fit inside this area of say 200 x 200 pixels but I cannot seem to calc the scale value 0.0 - 1.0

Any ideas peeps? Some images are not square and some images are smaller than the preview area (they could do with being scaled up to fit better also)
