I'm going to be generating thumbnails from user uploaded images. I'm
looking around at the libraries available to do this sort of thing and
there are three that look promising.
It looks like a lot of people are seeing problems with memory usage if
they are invoking RMagick often. Mini-Magick looks like it's wrapping
the command line and invoking ImageMagick which should be pretty fast.
ImageScience is using FreeImage and people say it's pretty fast and
isn't too hard on the server.
All things being equal, what have you had success with? Has anyone run
into any real gotcha's with any of these libraries?
