Can't merge a gif image with a png image.

[bkstorm]

I have two image: a GIF image and a PNG image.
the PNG image:

the GIF image:


I use the command below to merge two images:

Code: Select all

convert banana-bg.png null: \
\( banana.gif -coalesce \) -compose DstOver -layers Composite null: \
-set loop 0 -layers RemoveDups -layers RemoveZero \
finish.gif

and here is the result:

As what you see, it's not what I expect.

I try this command with another GIF image, it works fine.




What's the problem?
