I think perl with the image magick module can do what you ask... go to search.cpan.org and search for "image" you'll find a ton of stuff..
you can even generate images with them.. its very cool. rgds Frank -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Damian G Sent: Friday, August 16, 2002 3:40 PM To: lista-linux-newbie Subject: [newbie] read a pixel! i need a suggestion on programming languages. this is how it goes. i need to build a program that can tell me the RGB value of a given pixel inside of an image file. that is, load a graphic from file, and reading color values from it regardless of whether it's showing on the screen or not. i've tried kylix Open edition, but it fails to do it ( probably buggy libs ) as it loads and displays a graphic correctly on the form but when i try to read a pixel from it... the RGB value i get is wrong ( i think it's getting converted to 8-bit palette ) while the same code does run correctly on windoze's Delphi 5, ( so much for cross-plattform programming ) i hate having to reboot my computer ( or even loading a virtual machine ) just for the sole purpose of barfing fome clumsy lines of code -besides i'd like the linux binary- , so i've decided that i need to learn something other than pascal for killing time... can anyone recommend me a programming language that allows me to do this pixel-reading stuff and is as simple as possible? ( i will have to learn C sometime, but for the moment i think is a bit overkill... is there a choice? ) Damian -- Who is General Failure, and why is he reading my disk?
