    Help required to read PPM image files

    Hi all, I am a newbie in c programing.Can anyone please tell me how to read a ppm image file in c and obtain the rgb data contained in it in a mXnX3 dimensional array. For example, if the image has dimensions 128 by 128, then my array shold be of type arr[128][128][3]. Thanks in advance.

    I suggest Googling "PPM" and check out the format of the file. Once you know that, you should be able to read the pixel data quite easily.
