This is not a program code question.
I would like to know if you know an open source pdf editor based on mupdf.
In fact, I just need the following features:
- Highlight a select rectangle. (And the feature delete a highlighted rectangle)
- Add a line in some text (to indicate these text should be deleted or ignored). (And the feature to delete this line)
- Rotate a page or an entire pdf file.
- Add a comment (annotation).
Thank you in advance.
