I would normally use FreeImage, but I cannot find a Ruby wrapper for
this?

So if I can't find a wrapper for FreeImage is there any other suitable
libraries that I can use with Ruby?

Thanks,
Jim.

No ImageScience uses Free Image but does not expose much of it, it
appears to be a simple lib for creating thumbnails.

Thanks,
Jim.

If you have ImageMagick or GraphicsMagick available, RMagick...

have u tried RMagick ?

i found it very useful, a lots of functionality easy to implement.

Thumbnail can be made really easily with RMagick.

I am using RMagick in my rails based captcha plugin SimpleCaptcha(

and its working absolutely fine.

Rmagic looks like it will work a treat.

Many thanks again,
