[FEATURE REQUEST] Photo Filter "BluePrint"

[85pando]

Is your feature request related to a problem? Please describe. no, it is a new feature

Describe the solution you'd like Introduce a filter similar to "b/w""+"inverted" filter, that creates a "blueprint like" image. I.e., photographing a 2d sketch of dark ink on white paper would create a final image of a royal blue background with white/bright lines.

Describe alternatives you've considered

• using an additional app to apply filters after creating it with OSS document scanner
• ability to apply multiple filters and a colour shift (then you could also create "greenprints" or "redprints" (but who would want that?)

Additional context This is probably purely a geek feature.

@85pando i see your request. But then i will push it further. I should add a way to create custom filters based on existing operations so that you can stash them to create your own. Would require quite a bit of work but would solve many more cases

Yes, this would serve as well. ❤️
