Fred's ImageMagick Scripts
Posted: 2007-09-06T10:22:09-07:00
Hello Everyone,
I was relatively new to IM back in 2007, but have had many years of image
processing background. I have over the years, since then, developed some
bash scripts to process images using IM in some new ways and would like
to offer those to anyone interested. They are free for non-commercial use.
For commercial use, please contact me (fmw at alink dot net) to
license any of them.
I have posted these scripts on my web
site at:
http://www.fmwconcepts.com/imagemagick/index.html
You will find information about each script, examples and comparisons
and be able to download the scripts from this web site.
Any comments and feedback are welcome.
There is a Fred's Script forum here for questions or problems,
but feel free to contact me directly at my email address as well.
