Hi there,
Is it possible to turn off the dark mode on PDF preview? I am learning radiology and it’s kinda pointless when I am looking on RTG pictures lol.
Yes, use Custom CSS (What is Custom CSS and how do I use it?):
.dark-mode, .dark-mode .PdfHighlighter {
filter: invert(100%) hue-rotate(180deg);
}
It might have been due to an update but this code did not seem to work for me.
I tried this instead and it comes out perfectly:
.PdfHighlighter .pdfViewer {
filter: invert(100%);
}
The fix by @Marceau seems to introduce a translucent layer over the pdf after a recent update. Is there a way to remove this?
@hannesfrank Thanks for your answer. Do you know how I might change the background colour of a pdf to be less dark. I find reading white text on a black background too contrasty. I would like to make the background grey. Any help would be appreciated. I am not familiar with this stuff.
I suppose you can change hue-rotate parameter from 180deg to like 90deg
There are multiple possibilities, but all do somewhat affect the color of the pdf’s content (text images) as well:
(1) Most generally overlay a translucent layer over the whole pdf. You can even configure a warm, reddish background-color.
.pdfViewer .page .canvasWrapper::before {
content: "";
display: block;
position: absolute;
left: 0;
right: 0;
top: 0;
bottom: 0;
background-color: rgba(130, 120, 100, 0.2);
}
(2) Add a contrast
or brightness
term to the .pdfViewer
filter. Here you need to play a bit and see what you like. E.g. reducing brightness leaves black dark (inverted in /dark mode) while reducing contrast moves everything to grey.
.PdfHighlighter .pdfViewer {
filter: brightness(0.7);
}
Thanks guys! This has solved my issue. I am using:
.PdfHighlighter .pdfViewer {
filter: brightness(0.93);
}
