How can I programatically stitch many images into one?

Question

I am looking for a way to write a script that will take around 400 png images and merge/combine/stitch them into one.

I have spent days playing and failing with image processing libraries for Python and C++.

If anyone could point me to a specific language or library that you know has this feature that would be awesome.

Answer 1

The ImageMagick libraries and tools both support this.

Example link:

 montage -background #336699 -geometry +4+4 rose.jpg red-ball.png montage.jpg

Or

convert image1.jpg image2.jpg +append output.jpg

You can also blend over lapping photo's togeather as listed in this article.
