Hi, I have written two classes. One is a pixel grabbing class the other allows the user to open and display an image. What I now want to be able to do is use the image which the use opened in the RunProgram class and grab pixels from it using the grabPixels class. I have tried many different things but it doesn't work. Could someone please help?
Thank you
