Ruby wrapper for libjpeg to resize image

is there a ruby wrapper for the libjpeg library (http://www.ijg.org/)? What I'm开发者_如何学运维 trying to do is create an extension to the Rhomobile Framework so that I can resize images on my mobile app.

Thanks,

Nick,

The easiest solution might be to offload this work to an external service if possible.

I did find this though: jpegtran ruby gem jpegtran can be used to resize via libjpeg, if available on the platform.

not sure if it will suit your needs for mobile, but give rmagick a spin
