[SOLVED]Help with Image Cropping



  • Hello!

    I need to create something like a selector for an image so I can choose which part of the image i want to keep (whole image, bits and pieces etc.) AKA crop the image. I know I can use QPixmap::copy for the actual cropping but I need to get the point from which to crop, width and height (via a selector). I have no idea what to use to do this :D Any help would be much appreciated.

    Hi,

    One solution is to subclass QLabel and get the starting and ending point using mousePress and mouseRelease event making the rectangle from these coordinates.

    You can use a QRubberBand for the "selection effect"

    Hope it helps



  • Thank you I think I can use that :)
