Monochrome Mode

[piotrnajda3000]

Hi, I'm loving the app, thank you for your work.

I would like to implement Monochrome mode for the app with configurable background & text color, in spirit of how Okular does things:

Comparing to e.g. custom color mode of Sioyek, it's less pleasant/harmonious visually, due to images looking off:

Here's the light mode version for comparison:

However, I'm having trouble getting the build to run in the development branch, could you please help me with that? I managed to build the main branch and the alpha release branch, but not the development one. I'm running Ubuntu 22.04. Thank you in advance.

The development branch requires qt 6.7+. It seems that you are trying to build with qt5. But if the color of images is your problem we do have a preserve_image_colors_in_dark_mode config that preserve the light mode image colors in dark and custom color modes.

Thank you.

For anyone's reference later on, I managed to build the development branch by:

• initializing all submodules inside the repo,
• installing qt 6.8.1 & needed modules using https://ddalcino.github.io/aqt-list-server/
• making sure qmake path points to that installation (whereis qmake -> /home/piotr/6.8.1/gcc_64/bin/qmake)
• checking out mupdf submodule to master since fz_page_label is only available in 1.25, and the dev branch uses 1.19 version & then initializing it's submodules and doing a make -j$(nproc) for mupdf

I might have misunderstood something or missed a step of what I did, I'm new to C++ development, but it's building.
