I am new to Sumatra, and I discovered it because I was looking for a pdf reader which did the following:
inverting the colors of the pdf.
I am using the cmd : “-invert-colors”, which does exactly that.
Question: is it possible to save a new pdf that looks just like this (i.e. with inverted colors with respect to the first one). In other words, so that the default colors of the pdf are inverted, independently from pdf-viewer?
