Watermark Can Be Deleted, Add option to convert to image afterwards

[lawfulsoftware]

The resulting watermark can be deleted in Foxit PDF Editor by selecting and deleting each object. Running the watermarked PDF through the Flatten process did not prevent deletion.

Further to this, it seems to be an issue with most other programs. I have tried other online services as well as Foxit. It seems that flattening does not affect the watermark layer.

@Frooodle Perhaps an option could be added to automatically pass the watermarked PDF through a module that converts the PDF content to image so the resulting PDF cannot be edited.

This option exists for a few other features (image conversion), seems reasonable to add it as a extra checkbox

And yeah flattern is only to remove interactive elements like textboxes

For new devs taking this, you can refer image conversion from https://github.com/Stirling-Tools/Stirling-PDF/blob/main/src/main/java/stirling/software/SPDF/controller/api/security/RedactController.java#L81

Hi, I'd like to work on this if nobody else has yet

[Isaac-Whiz]

I would like to take on this issue, however am requesting for more delight because it seems am not getting this issue right. @lawfulsoftware are you suggesting that the conversion process should not allow deletion of a watermark automatically so that it requires consent of the user to get it deleted? Thank you.

[lawfulsoftware]

@Isaac-Whiz @N-Smith-00 A watermark should be permanent. As currently implemented, the watermark can be deleted. To make it permanent, the watermarked PDF could be converted to an image and then back to PDF. Since the conversion to an image would merge the layers, it would be difficult to remove the watermark without resorting to AI or graphic editing software.
