This file was created to be viewed on a television screen...

For any future travellers who find themselves here, the cause is that the image length and width have a different PPI setting. In my case it was 1px out.

Thanks for the reply. Understood. Adjusting upon opening is what I'm doing. I still haven't figure out though why the images are being exported in this fashion to begin with. Perhaps it is the way the original PFDs were created...

Without seeing the image, I cannot judge exactly what the problem is, but with a high probability you have an image that does not have square pixels. See here for more information on this: Pixel aspect ratio - Wikipedia .

This is a leftover from the cathode ray television sets, where it was quite easy to stretch the "pixels" by a factor, leading to no square relation ships. Therefore, if the picture looks like compressed (circles are ellipses, squares rectangles, faces and human bodies stretched...), you need to adapt the horizontal resolution.

For today's systems, however, square points are best.

What Elements tries to tell you is that if editing the file without touching the pixel width, you need to display the picture via a video monitor, as scaling up and later scaling down will result in errors that may be seen at some stage.

May be elements has also an option to adapt the pixel width on screen without modifying the image, only the display of the image.

Anyhow, I would dare to say that non square pixels are nowadays obsolete. A one time conversion should not harm your data visibly.
