having some trouble trying to be able to manipulate PPM images. I want to be able to desaturate and also double the scale of them. im a first time user of haskell so am not very familiar with it. any info would be great! thanks!
Nothing wrong with asking for help, but before you do, please read: http://www.haskell.org/hawiki/HomeworkHelp After you read that and follow its advice, we would love to help with *specific* questions (code help or algorithms, for example). I have a few questions for you: Do you understand how to do these image manipulations, for example, in another programming language? Are you confused about how to do this in Haskell? Or both? If these manipulations are difficult, try something simple, like inverting the image or keeping only the red channel (zero out blue and green), anything to make sure you have a handle on the code. Thanks, Jared. P.S. After googling around for "haskell image manipulation" (in the hopes of finding some Haskell image lib like VIPS [1] or the Python Imaging Library [2]), I found the assignment spoken of http://cs.anu.edu.au/Student/comp1100/assts/asst1/ just so everyone knows. BTW, does Haskell have an imaging library that people usually turn to? (Or should I add that to my list of cool projects that I need to get around to ...)
