[GM-bugs] Problem resizing animated gif with transparency

[Dan T. <ts...@gm...>]

Hi,

I'm running GraphicsMagick version 1.3.10.

I have a problem with resizing animated gifs with transparency in
it.

If I take the following
picture:http://dl.dropbox.com/u/574561/tiger.gif
<http://www.online-image-editor.net/examples/imagemagick/kitty.gif>

And resize it with the command:
"gm convert tiger.gif -coalesce -resize 80x80+0+0% out.gif"

I get the following result:http://dl.dropbox.com/u/574561/out.gif

(Transparency is gone and turned black)

I have also seen that transparency sometimes turns to grey.

Is this a known bug? Are there any workarounds?

Regards,
Dan
