I would like my users to be able to interactively crop an image I have in memory (I can write it as a file if necessary).
Is there such a library, compatible with the GNU-GPLv3 Open Source license?
- Input: an image as memory object (file would be OK too as long as required format is common enough)
- Output: cropped image, preferably with a choice of PNG or JPG
- Interactive: Crop the image by moving cursors/rectangle or similar
- Works offline
- Zoom feature not especially needed
- Quality loss is OK
