Home / Comic Book Background Color (Also presentation mode)

Comic Book Background Color default is black and
tried to change to different - no success.

If it possible, how ?
If not - why ?

Thanks

Not currently possible unless you use save as PDF

Why?

That’s a good question most image viewers use a white background since it needs to be fully black or white end of alpha color range and the code suggests the use of white ! sumatrapdf/EngineImages.cpp

Personally I prefer that it somehow defaults to black as its easier to see the edge of white framed photos or comic pages.
