           Product: okular

          Platform: Fedora RPMs
                OS: Linux
            Status: UNCONFIRMED

Hi. 

Currently Okular lake very important feature: "eraser" which allow to erase
contents of pages of PDF (any original content). Annotations that added by
Okular already can be removed by right click any of them then click "delete". I
mean by "eraser" is eraser able to delete any contents including original (non
Okular-based annotation contents).

"Eraser" should has setting can be reached by right click over it's icon. This
eraser setting should allow user to select:

- shape of eraser whether circular or square,
- size of eraser. It should be available in 3 sizes: small, medium, & larg.
- color of eraser. It should be white by default, but give user other options
like black, yellow, & other colours ..... .

"Eraser" operation should be secure erasing (what called "reduction") by which
when user erase something it will never remain hidden under the hod.

"Eraser" when activated it's boarders should be visible by thin boarder so that
user can see it's area of operation. I mention this due to that some
applications like Xournal (on Fedora) it's eraser has no such visible boarder !

More importantly using this eraser should never result in increase size of PDF
file. Okular already has this golden feature (not result in increase size of
PDF file by annotation, so please keep it & do not break it).

Best.
