Convert CBR for the Kobo Nia漫
CBR is a RAR archive of comic page images. The Kobo Nia has a 758 × 1024 screen, and CBR files that were not built for it read badly: pages rescaled on the fly, spreads split wrong, contrast off. MangaConverter re-renders every page for the Kobo Nia's exact resolution, so nothing is resized on the device.
