As such you can zoom the text in atril to at least 400%. You can also invert the colours, which may increase the contrast. Assuming you can see tolerably well, it's difficult to see how that is unreadable. I'm not 80 yet, but I'm pretty close to the legal definition of blind here, and I can see pretty well. > I opened the PDF with LibreOffice DRAW. > Experimented with "Viewing" a region as "Greyscale" or "Black and > White" rather than the default of "Color" looks promising.
