For a project we need a camera similar to what one has in whatsapp.
After taking a picture the user should be able to crop, rotate and draw simple line on the image. The user should be able to revert any action made on the image (crop, rotate, draw).
We want to fund the initial release of the library and plan to release it as open-source under our github account. The library should work on iOS and Android.
You can use [login to view URL] for taking the photo.
[login to view URL] for rotating
[login to view URL] for cropping
[login to view URL] - for drawing on the image (or better)
