Yeah the article says these "aren't used anymore," but my image viewer (sxiv) complained that the gif was corrupted until I put something there. It still displayed the image, but it also complained afterwards.

In the case of viewnior, it said that the resulting image has zero size and displayed nothing. That statement of it not being used seems false.

Aha, thanx for the info, I didn't know. So the canvas width and height should be the same as the width and height?
