No, it's not you. 6x4 is an aspect ratio of 1.5:1 whereas 640x480 is
1.33:1 - hence your distortion. Scale it to 640x420 for a better result.
Now here's my question: I've often seen this business of 72dpi as being the
same as screen resolution and therefore the optimum for scans to be
displayed on monitors. But, I can set my 15" monitor to 640x480, 800x600,
1024x768. So the dpi is going to vary by quite a lot. While the physical
dots per inch of a screen might well be 72, surely an image scanned at that
resolution will not necessarily be *displayed* at that - it will depend on
the relationship between the dpi of the screen and the video card settings.
Won't it? Or am *I* missing something?
