No. The checkboard pattern is configurable (see Preferences/Display) but the pattern or color you choose is not actually a layer. It's just a way of showing where in the image some level of transparency exists through the existing layers. You can't see, for example, your desktop through that transparent area, however.

Thanks, Adonj

That's exactly what I was looking for! To see the desktop through that transparent area. Therefore I see there is no possibility of doing so while using Gimp? Is that only achievable in other animation software and may be as well in Gimp in a future version?

Do animated gifs support transparency? I've never tried it...oh, wait, yes I did, just the other day I made an animated gif icon with transparency for someone's web site. Funny, I answered my own question:)

You can preview the transparency by using the GAP player (Filters->Animation->Playback). When the player dialog opens, right click on the canvas area and choose "Detach". Then drag the canvas area over your desktop. The animation will playback over your desktop with transparency rendered. It may not be a perfect render, but it should work.

Saving to PNG preserves full transparency but I don't think PNGs support animation (use MNG instead, I believe). I could be wrong about that as I don't do much with animations.

Saving as GIF will reduce the palette to 256 colors and reduce multiple-levels of transparency (re: 0%-100%) to a single state of transparency (pixels are either fully transparent or they are not).

Animated GIFs play fine in web browsers. PNGs (non-animated) with transparency work well in modern browsers but suck in older versions of MSIE. That's the browsers fault, not PNGs fault.

I use the GAP player when I need to. Saving to PNG will have layers merged or flattened. That doesn't work for animations.

Yeah, you have to save as MNG instead, I'm pretty sure. But MNG probably isn't supported in web browsers all that well. I assume you're trying to do this for the web or you wouldn't even consider GIF animations.

Saving as GIF is my final result. To demonstrate the problem I'm having: In my animation I have two identical frames of an object surrounded by a transparent background which is represented by small gray squares. If I move the object slightly in one frame, then play the animation, and detach the image, then drag the image which is now stepping from one frame to the other to the desktop screen, the area around the object which has had the object displaced, shows some of the gray squares each time the image steps to this displaced image frame.

Yeah. As far as I know, that's how it works.

That plug-in has nothing to do with GAP, the GIMP Animation Plug-In. It is bundled in the standard set of plug-ins that ship with GIMP.

By the way, will GAP be adapted to GIMP 2.6, and when? I really hope so!

What do you mean? I used it with 2.6 today. No adaptation needed.

Do you mean a Windows binary of GIMP-GAP? There should be no reason that you cannot use the currently available one.
