@Leir: Yep, perfectly normal, especially on the PW. 332x500 to 758x1024 is a somewhat severe upscaling, and while the upscaling algorithm is good, it's still an image upscaling algorithm, so a bit of blurriness is to be expected (we're not in CSI, where pixels magically appear from outer space when zooming ^^). And the two white bars on the side are an artifact of keeping the aspect ratio
. That said, it should more or less look the same as the 'Go To > Cover' in the reader
.
@7hir7een: To be perfectly honest, I kept the aspect ratio intact partly because that's what the reader does, but mostly because I abhor looking at stuff that doesn't respect AR
.
That said, it's pretty trivial to change:

(It's a shell script, so the usual warnings apply: don't touch anything else, use a real text/code editor that honors *nix line endings & doesn't decide to put an UTF-8 BOM, etc
).
