I made a tiny gif awhile back and am trying to remove the background from it. However, when I save the file (using photoshop CS5) it keeps altering the image after export. I saved the 4 frames of animation and tried using an online gif creator and ended up with the same altered result. I think it might be the gif compression in combination with the tiny image.
Here's how the animation should look:
And here's what it looks like after removing the background:
You'll see the 2nd bar from the left doesn't move at all.
This is for a java project I'm doing, and FX has no support for apng so I'm stuck with gif.
