accessing pixels in an image - histograms help?
hi everyone, I have a question regarding images. I was hoping to create a program that looks at the pixel values in images sort of like a histogram. Anyway in my mind (im not a great programmer and this will probably be wrong I imagined it just being like reading a text file character by character only i would read an image pixel by pixel reading each ones value as i go along. Could it really be as simple as this? If anyone can point me in a starting direction i would much appreciate it or even websites i could possibly look at to research this?
