Merge an animated gif over a static png at a specific location using ImageMagick

Question

I have managed to paste an animated gif over a static png and obtained an animated gif from those sources with the following command.

convert canvas.png animation.gif test.gif

and it works, but the animation and the canvas share the upper left corner, which is not what I want. By reading a little I discovered that I have to use either the -composite option or the command, but I have not found examples of the right syntax to use. I tried this:

 convert canvas.png   animation.gif -geometry +780+275  -composite test01.gif

which gives a static image with just the first frame of animation.gif I tried other syntax but just produces errors.

What is the right way to accommodate the animation?

Answer 1

Try the following in Imagemagick. It takes a special null: operator to separate the two images and -layer composite. Also you must use -page or -set page rather than -geometry when using -layers composite. The following is Unix syntax. For Windows, remove the \ before the parentheses.

convert canvas.png null:  \( animation.gif -coalese -set page +780+275 \) -layers composite -layers optimize test01.gif
