Feature description

Support in the image editor for censoring images using a blur/pixelation.

It would work like the drawing tool (ie. use your finger to 'draw') but instead of overlaying a colour, it would blur/pixelate the image.

Optionally: have an "auto-censor" mode. automatically detect "significant" components and allows tapping on them to censor the entire component (tapping a second time un-censors it). eg. detect areas in the image with text in them. tapping on an area with text will pixelate/blur the entire area. also detect things like profile pictures, faces, dates, addresses (sensitive things like addresses are automatically censored when entering "auto-censor" mode, however tapping on them will un-censor it.), etc. see additional details for an example.

Why do you want this feature?

Support for pixelation/blurring parts of an image is something quite nice that is currently not supported. The default screenshot editor for my phone supports this already and I find myself using it somewhat often.

Additional information

Example of the "auto-censor" mode, as done by my built-in screenshot editor app:

I have a bunch more on my nextcloud instance here if you want (a bunch that are spread around other folders as well, but there's other stuff in those folders too. eg. just my downloads folder, so I'm not gonna share that lol): https://nextcloud.solonovamax.gay/s/sooccRcfLc5SEds
