I'm trying to add a border to an image, and the color comes out wrong. I created an image with a black background, composited two other black&white images onto it, and then Trim it. Then I put a 5 pixel border around it, with bordercolor=>"black", and it actually comes out light gray, like this:
The border is kind of hard to see in that image because it's close to the background color of the forum post, but it's there. Any idea what I might be doing wrong?
