Since I was in a releasing mood today, I thought that I would make available my imgop library. This isn't rocket science but has satisfied my needs for a while now. Here is the abstract:
The imgop library implements a number of operations on images. The library implements some these operations in pure Tcl and some other operations through the help of ImageMagick, without requesting any dynamic binding to the program.
I hope that it can be of any use to some of you. This is released under the new BSD license. The home page with further instructions and a download link is at: http://www.sics.se/emmanuel/?Code:imgop
