I have an existing PHP driven website. I need to fix a few new features on this site. I have an image cropping feature on the site.
I need the following changes:
1) On the crop screen, I will need to change the dimensions of the crop. I will give you the new dimensions
2) On the crop screen, I want the standard crop drag area to be similar to the canvas used to display the image (the canvas is not rectangular)
These are the main two items.
