SUMMARY I need a pdf file including my signature in a non-editable format.I have created a respective custom annotation. As there is no option to "flatten" annotations, I thought printing to pdf would be a suitable workaround. This workaround works for other annotations, but not for stamps (even for non-custom). STEPS TO REPRODUCE 1. Open a pdf file 2. add a stamp annotation, 3. print to pdf (tick print annotations). OBSERVED RESULT A pdf without stamp annotations EXPECTED RESULT A pdf with non-editable ("flattened") stamp annotations SOFTWARE/OS VERSIONS Linux/KDE Plasma: Kernel 5.3.0/ KDE plasma 5.16.5 (available in About System) KDE Plasma Version: 5.16.5 KDE Frameworks Version: 5.62.0 Qt Version: 5.12.4 ADDITIONAL INFORMATION
Yeah, basically "stamps don't really work", they just work if you never leave Okular user interface. There's various bugs about it
