I'd reccomend Imager for most simple graphics stuff now, it handles more colours and installs easier than either PerlMagick or GD. Unfortunately it doesn't have the huge variety of extensions that GD has for charts and stuff but I am working on Pie and Radial charts possibly even some 3d bar and other charts later. regards, A. -- Aaron J Trevena - Perl Hacker, Kung Fu Geek, Internet Consultant AutoDia --- Automatic UML and HTML Specifications from Perl, C++ and Any Datasource with a Handler. http://droogs.org/autodia

You will need to install libpng, zlib and the GD graphics lib before installing GD.pm And if it's not critical to use GD specifically, have a look at the alternatives. such as image magick. It also needs the appropriate graphics libs and stuff installing though, but that's just the nature of these things, you may have more luck getting one to work than the other though. Personally, I went off GD around the time it removed gif support, and hordes of customers needed it, so it was a hassle to get appropriate versions of GD, php, apache and openssl that would all happily compile against each other. the hatter

GD::Text will probably fail tests. I've emailed the author about this and
we're at a loss what to do. Don't worry about it, it seems to work fine.

Should I count on them being fairly straightforward, or is use of them more difficult to get right than it might seem? Yes, they're fine. They're _wrappers_ around GD, so you'll need to install GD on the web server that you're running the script from. I suppose that might be an issue in some cases. GD::Graph just takes a two-dimensional array and plots it nicely. Something like: (untested) my @data; $data[0] = ([Segment 1,Segment 2]); $data[1] = ([20,80]); my $graph = GD::Graph::pie-new(400, 300); $graph-set( title = 'Title here.' ); $graph-set( dclrs = [ qw(cyan lorange) ] ); my $gd = $graph-plot(\@data); binmode; print $gd-png; - Chris. -- $a=printf.net; Chris Ball | chris@void.$a | www.$a | finger: chris@$a That's just kitten-eating wrong. - Richard Henderson, on linux-kernel.

You will need to install libpng, zlib and the GD graphics lib before installing GD.pm I had real bother getting this to work on RedHat 7.2 and 7.3 but it did work OK on my Windows box (ActivePerl with cygwin). The problems I had a most likely down to my inexperience but I can faithfully say that this caused me more hassle than *any* other module I have installed. However as everyone else has stated, once it is installed using it is a sinch!
