I'm new to RMagick and am looking for how you can set the optimization on a jpeg image. Can someone point me in the right direction? Thanks! Tom

If by "optimization" you mean compression, see here: http://www.simplesystems.org/RMagick/doc/comtasks.... If you mean color reduction, see here: http://www.simplesystems.org/RMagick/doc/image3.ht...

Thanks! The compession is definitely what I am looking for. I'm trying to use it dynamically when the image is rendered to a Rails web page. Currently, I am using the follwoing to render the image: send_data myimage.to_blob, :disposition => 'inline', :type => 'image/jpg' I tried using myimage.quality = 50, but it looks like that can only be done on a write. Is there a way for me to set the quality when rendering the image? Sorry if this is newbie stuff! --Tom
