in reply to Manipulating Graphics with Perl .. Image Magick Vs GD

I don't personally like GD much, but that's just my irrational bias. I submit you need to have a look at Imager before you decide on any one approach. It's as lightweight as GD but does much of what you'd otherwise reach for Image::Magick for.

The problem I ran into with this set of modules is notorious lack of documentation - you'll have to dip into the source, the example programs and take trips to its site and the mailing list archive frequently.

Makeshifts last the longest.

    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.

      Makeshifts last the longest.

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