Description

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.
