-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi there, Does somebody know about a rather small graphics library for Ruby? RMagick is way to big and complicated to install for my purposes (just rectangular picture cutting and pasting in PNG images) and additionally it is complicated to install for Ruby 1.9 on Windows which is a must-have criterium as the application will be distributed not only on Linux systems, but also on Windows ones (by means of using OCRA).

The only thing I can think of would be to ‘wrap’ java’s built in graphics2d class.

Maybe it’s possible to convert the PNG to something simpler first I can work directly with as a string and afterwards converting the result back to PNG, but I’d like to do it in a clean way–and for bigger images converting in such simple formats causes quite big strings I think. Additionally, the back-and-forth converting itself will take some time and even if that’s not a critical issue in my case, I don’t want to do unnecessary operations like this. However, I just found a gem that perfectly fits my needs[1]: chunky\_png ( [chunky\_png | RubyGems.org | your community gem host](http://rubygems.org/gems/chunky_png) ). Thanks to everyone! Vale, Marvin [1] The paste problem is accessed by chunky\_png by just directly operating on the pixels. This maybe slow, but seems to me like a very clean way and chunky\_png does not have any external dependencies which makes it even more attractive to me. However, if you have better ideas, I’m always open to new suggestions. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) Comment: Using GnuPG with Mozilla - [http://enigmail.mozdev.org/](http://enigmail.mozdev.org/) iQEcBAEBAgAGBQJMpgABAAoJEGrS0YjAWTKVXTsIAIktJelnYkiCBuLvg61pe9om hBtEo6g2v4D6GhZ7JLkKO7osoickfNNXvGTxWmgE+zoS2pIig2U4aXh6c2qGqa2x B1SvS2uGDXQ6lu3rghxca90WJ/jx8YABVA/AfIYwgLPWN7ToxbEGdDYVzf3RyV7P jQeK2C2MWfut7zhCBoYMIqOypTaW5BcIkyUlbZNmjAXYDK49McsSW2fNuFL8dkzi LcfBA8nj/m1P/Pe5q/57YuSgigHCf733SLgS83ySJrPDeapnn8Va0zT9HmY/HAMi WESa6yjY+L+4CCpQpIHl9QgY8W27RlKPz0OpzihFsGkjA4N44RmzlKIBs1ugkZ4= =PI++ -----END PGP SIGNATURE-----
