Hello,
If you are looking to change the aspect ration of a still image to 4:3
then you could either stretch or shrink the image using the Stretch/Skew
tool that is under the Image menu or you can crop the image using the
selection tool, copying the selction to the clipboard and then pasting that
copied image to a new picture that has a canvas whose attributes make it a
4:3 aspect ratio. You can change the attributes of the canvas by selecting
ther Attributes tool under the Image menu.
Best regards,
Chris.
