Create Image in perl

FiReWaLL has asked for the wisdom of the Perl Monks concerning the following question:

Hello, everyone... It has been sometime, since I was last here. My english got worse (I learned german), but I still program in... what's the name... ... ... PERL! Yes! Perl!

Does anyone know if there's a possibility to CREATE images in perl? I mean, I nice little yummy pizza chart, for example?

I DO know that is possible to transfor an image from Binary to ASCII, and then you could... read the colors pixel by pixel, or something like that... but.. it should have another way.... (or not?)

As a start, I'd suggest taking a look at the Graphics section of CPAN. Perhaps the most widely used module is GD, which is a Perl interface to libgd, a graphics library that can create and manipulate images in PNG format. You can use the Perl GD::Graph module to make pie/pizza charts. GD is quite flexible, in that you can compile it with support for JPEG, and with support for rasterising TrueType fonts into your image, if you've got the appropriate libraries installed on your system. ActiveState also offer pre-compiled binaries of GD for ActivePerl on Windows. I haven't used it, but the Imager Module, also on CPAN, seems to have some features that GD doesn't have - any other folk on here got experience with using it? /=\	[reply]

You need to look at the GD distribution. You can create PNG and JPeg images with the appropriate support libraries. The main library is supported here. But you'll also need the Perl modules from CPAN. If you are running on Windows then you should be able to get a ppm for it all.	[reply]

On top of using GD also check out DBD::Chart. I provides a DBI interface to charting, you can insert your data into "tables" and then generate charts and graphs off of it. Or you can pull the data out of your existing tables and chart it. It supports a wide variety of highly configurable chart and graphs. It also will generate imagmaps for client side mouseovers and navigation. All in all, a great package. The kind of package that you can use to blow your boss or client away with. -pete Entropy is not what is used to be.	[reply]

There is also an O'Reilly book (don't know if it's still in print or not) Programming Web Graphics with Perl and GNU that might be helpful. Spring: Forces, Coiled Again!	[reply]

i don't want to steal Hackmare's thunder, but you might have a look at svg, as well. ~Particle	[reply]

One thing I haven't seen mentioned here is ImageMagick. (http://www.imagemagick.org/) It has perl modules in the distribution.	[reply]
