Sumatrapdf: implement night mode (dark mode)

[marletto]

normally, a pdf file is black character + white background,
I wish to show pdf as white character + black background.

[adrianstaniec]

Yes! that exactly the feature I am missing ;]

For me it would be enough just to swap those foreground with background colors.
That would work for a lot of simple documents already.

And extra would be to make the links lighter (usually there are in dark blue or dark red).

[johndob]

I would like to have that too

You can already do this. Add the following lines to your Advanced Options, in the relevant places:

MainWindowBackground = #555555
UseSysColors = false

FixedPageUI [
    TextColor = #d7d7d7
    BackgroundColor = #2f2f2f
    SelectionColor = #f5fc0c
]
EbookUI [
    TextColor = #d7d7d7
    BackgroundColor = #2f2f2f
    UseFixedPageUI = false
]

@SicariusNoctis, thanks very much, solved my problem.
There is still a minor issue: how to customize the bookmark view's text color and background color?

This is available using Themes in the latest pre-release version of Sumatra, v3.2.10662, via Settings -> Theme -> Dark/Darker.

[johndob]

and why is it missing in newer 3.2.10688 ?

Theming was an experiment but it's not ready and most likely I won't be able to make it ready for the next release so it was (temporarily?) removed.

It's not needed for the night mode.

I found the solution. My setup is all black boarders and black start-up screen and total black in full-screen with white text.

Setting/Advanced Options, add line GradientColors to FixedPageUI then choose your hex color. Here is my setup for all black and white.

MainWindowBackground = #000000
EscToExit = false
ReuseInstance = false
UseSysColors = false
RestoreSession = true

FixedPageUI [
    TextColor = #ffffff
    BackgroundColor = #000000[enter image description here][1]
    SelectionColor = #f5fc0c
    WindowMargin = 2 4 2 4
    PageSpacing = 4 4
    GradientColors = #000000
]

Hi,
I see that on the website the command line argument -invert-colors is flagged to be removed. I think it is a very useful feature and it should not be removed.
My use case is that I build from source very often and I can implement the command line argument into a custom build script. Specially in the dim light and when my editor is also in a dark color scheme, suddenly switching to a bright screen is hard on eyes.

@kjk perhaps consolidate with "I can not create a dark theme" #1023

[kjk]

This falls under theming support i.e. #898
