Hi all, I need to implement a graphical curve editing tool.
The interface would be similar to the Curve tool of Gimp or PaintDotNet, aiming at image adjustment.
The user can edit any point on the initial curve(y=x line) by clicking and then dragging the point via mouse move.
The curve then should instantly be updated based on the new position of its edited point, taking the proper shape via mathematical equations.
I have basic knowledge about QGraphicsView and QGraphicsScene, but this task seems a bit harder for my level of experience.
Any ideas or any directions to similar available applications/source codes are highly appreciated.
