Hi, I was wondering something: What would be the optimal PPI to use when exporting PDF pages to PNG to create a CBZ? I was using poppler to find out what PPI was used for each image on every page but it produced huge PNG files (like 10345x15518 pixels), and it takes way too long to do it. If I use ghostscript I can export using a fixed PPI for all pages, and it's much faster. My device is a Kobo Glo HD, which has a 300 PPI screen. Would something like 600 PPI be enough for KCC to use as source?
