Text contrast in PDFs
Hello
I have a PDF version of a magazine I would like to read on my Kobo Forma. Sadly the magazine uses a font with thin letters which makes it hard to read and I'm not really sure the text is even 100% black. I tried increasing the contrast in KoReader which helped but it also turns all of the pictures black. Is there a way to adjust the contrast only for fonts in a pdf file or to make all of the text bold?
