With smaller screen resolution e-readers the pages (images) should also show up in their full resolution so that the reader will need to scroll to see the whole page. Only like this it is possible to effectively read the texts in the images. I would like the pages/images to always show up in the original image resolution (in this case 1536 pixels by 2048 pixels) independently of the e-readers screen resolution. I am trying to convert some Cbz or Cbr comics into Epub with Calibre and I am facing one problem: with the converted Epub the comic pages (= pictures) do not show up in full scale on the e-readers, even though the resolution of my comic pictures are very big (1536 pixels by 2048 pixels).
