Question Why is a picture always changed during CBR file conversion?
I did a CBR --> EPUB conversion and noticed blurred pictures when viewing.
Whatever I did with calibre settings, the pictures where always converted into 527 x 754 pixels (originals are about 1423 x 2033).

I used the following (mostly default) predefined values:
Preferences > Conversion > Input Options > Comic Input: default values
Preferences > Conversion > Common Options > Page Setup > Input Profile: Default Input profile
Preferences > Conversion > Common Options > Page Setup > Output Profile: Default Output profile
Preferences > Conversion > Output options > EPUB output: Preserve cover aspect ratio
(Not mentioned settings are not changed)

I did a single file conversion with:
convert books > convert individually, accepted all default values via Ok.

Not happy with the result, I tried:
convert books > convert individually, Comic input: disable comic processing
Same result

How can I make calibre refrain from converting the pictures?
