invert colors – original article

With a simple shortcut switch, SumatraPDF can invert all colours within the document and this colour inversion is not limited to text, but also extends to embedded images too.

Here’s how you can go about doing it:

  • Create or duplicate a shortcut to SumatraPDF (and optionally, give it a different name) in a location of your choosing.
  • Right click the shortcut and click Properties.
  • Under the Shortcut tab, click on the Target field and add the below
     -invert-colors
    

    to the end of the line as shown.

  • Click OK and you’re all set.

Now you can use the regular shortcut to open up PDFs to view them in their true glory or you can use the new shortcut with the switch to open up PDFs for a good, long read.

For the purpose of illustration, here’s a non-inverted vs. inverted comparison of the same file.

Hope this is of help to some. Cheers.
