in thread Manipulating Graphics with Perl .. Image Magick Vs GD

I've never heard of Imager (and don't really have time to play with it now) - in what ways is it better than GD?

I use GD quite extensively, but exclusively for image generation (so I've never had to touch Image::Magick), it'd be great to know if there is a module out there that can improve the quality of my life.

    It doesn't depend on an external library for its basic functionality - it's an completely independent and pretty slim XS module. It offers more and more flexible transformations (and is supposed to eventually offer a lot more yet). The killer criteria for me - it antialiases drawing primitives and supports TrueType fonts via FreeType, also antialiased. It is very easy to generate high quality plots using Imager::Plot (I used it for an interactive math report f.ex). I found it pretty easy to work with, overall, and quite intuitive once you figure out in spite of the lacking documentation.

      Sweet.... any speed / memory comparisons done between imager::plot & gdgraph when you are producing many 300x300 graphs? (Twists Aristotle's arm... :) )

        It handled the load from about 20 computers hitting the page nearly simultaneously during the math report just fine, but I don't have any hard numbers and I didn't compare with GDGraph at all. I was in a hurry and needed something that did what I wanted with as little effort on my part as possible. GDGraph wasn't it. From how it handled that load though I'd expect it to scale up quite a ways before performance becomes an issue.
