Sumatrapdf: Easier way to Invert color

[lollita]

I would a button or option to invert pdf colors.

I love how bitmap colors are inverted but, when viewing a person's face,
I want to see it normally ( sans inversion ).
I'd like to hit an icon|key to toggle the inversion.

In browser is possible to invert text only with css.
Do it is possible in pdf?

[kjk]

No, PDF doesn't work that way.

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 mine setup for all black and white.

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

FixedPageUI [
    TextColor = #ffffff
    BackgroundColor = #000000
    SelectionColor = #f5fc0c
    WindowMargin = 2 4 2 4
    PageSpacing = 4 4
    GradientColors = #000000
]
