From: Huub on 9 Jun 2010 00:40 Hi, I'm using Perl to print from database, which works great. Now I'd like to print a .JPG picture with it. However, searching CPAN I find a LOT of graphics modules. Any recommendation which one to use for this? Thanks.

After searching CPAN, I looked better at CD::Graph and Chart and found both very similar, and lacking for my purpose. They are good though. I then looked at driving gnuplot from perl, and it will probably serve your needs. It's incredible what you can do with gnuplot. It still didn't need my needs (for every x-pixel, draw min, max and avg) so I'm currently deriving from GD::axestype to do it myself. HTH, M4

The modules on CPAN are for *creating* graphics. Is that what you want to do, or do you simply want to print an image? Also, print to where? If this is a question about web programming, it helps to say so up front - people use Perl for a wide variety of tasks. sherm-- -- Sherm Pendley <www.shermpendley.com> <www.camelbones.org> Cocoa Developer

"print" like in print to a sheet of paper? Normally you would use whatever means your OS provides for that and normally yes, you could initiate that via a Perl program, too, just like you would initiate any other external command from a Perl program. Or "print" like the print() function in Perl? Well, that is mostly for text although of course you can use it for binary data, too. Or what "print" are you talking about? jue

I am talking about printing to paper and the intention is to print an existing jpg picture on the paper after which the data from the database is printed. Reading the other reactions, I think it would be easier to first print that image using Gimp or so, and then re-use the paper using Perl to print the data. Though it would take at least twice as much time. Any suggestion welcome. |
