I am generating a series of text images using IM... essentially I create a large layer (1280x1024), put some text at the center of it, add some shadows or other improvements, then I trim it. However, I want to expand the image back out to 1280px wide while maintaining it's trimmed height.

I read that extent can be used as below to set just the height: But trying the option below doesn't appear to work at all. I would like the above to extend the canvas to 1280px wide, maintaining the height. I would expect that it would use gravity to determine which side of the canvas to add to.

Am I doing something wrong, or does extent only allow vertical 1 dimension adjustments?

Nevermind... I figured it out. It appears what was happening was that I was forgetting to set the background to none, which made my white text disappear on a white background.
