in reply to Pure Perl - Crop and Resize Jpeg Files

Could it be done? Yes. But I don't think you understand what you're asking. Making a pure perl (or any other language for that matter) imaging library is a large undertaking.

Even resizing images is a complex subject and there are numerous ways of doing it, some better suited for the task at hand than others. Plus perl would be slow (maybe PDL could help here)

I'd be suprised if PHP,Ruby or Python weren't using GD or Image::Magick as well underneath the hood.

It would probably take you ten times as long to create such a thing, than learn the ins and outs of installing and interfacing third party software. Plus once you've overcome that problem, you'll be able to utilize dozens if not hundreds of third party libraries for any number of tasks.

    Actually they are, but maybe the modules are already available on the target server for one of these (well probably for PHP indeed), that would ease work quite a bit for the OP.

      That's a good point. Though I would think most hosts would have magick or GD on it.

      As anecdote, don't know wether it's still the case, but Yahoo! Store used GD from within the LISP software.

        AFAIK Yahoo Store was entirely rewritten in Java.
        update:the gory details are certainly available on Paul Graham's website...
