I have a project for school. It's like curves in photoshop.i have to change the balance of white and black so that the contrast of the image to be correct. 

I have to read the pixels from a RGB image.select 5 point to determine my curve and make a new image from the first image but with the correct contrast changing pixel by pixel.
i don't know how to make a new image from another, and change the pixel values.
