Image manipulation in Ruby?

[neobuddah]

Hi all

Anyone know of any image manipulation libraries with exif support in Ruby? I'm looking for something that's similar to PHP's built-in JPEG/PNG functions.

Cheers!

http://rmagick.rubyforge.org/ should do the trick.

I found Ruby GD is best. However it doesn't seem to work on Windows, so use a Linux machine for this.

To compile ruby gd, you need lib jpeg/png and freetype 2 on your dev machine. Ideally you should compile these your self or install the dev packages. Likewise when you compile these, you need to explictly say the path for these libs. The easy way is just to use Gentoo (be warned Gentoo used to have a fixed dependancy on x11 / open GL for some reason, which is a pain for server machines).

rmagik is easier to install, but I perfer GD because it has typography stuff that i use. I dunno if this has exif stuff you are looking for ....
