2. How did you "simply resizing pages to fit within the Libra's screen without scaling is enough. I set them to gray-scale at the same time. "?
I extract the .cbz file into a folder, use ImageMagick's command-line "convert" tool to resize all of them in bulk, and zip them back up again. The following example produces nice-looking results that fit each page within the Libra's screen without any stretching:

Code:
