image aspect ratio: where to add argument?

dsfgxnchjb · 10-01-2014, 03:21 PM

Default is set to stretch, leading to totally horrible results with any conversion having images.

There is this setting:

--keep-aspect-ratio

But WHRE do I set this when using Calibre GUI for conversion?

Thanks.

Theducks answered your question, but this setting is only for the cover. Calibre does not alter the aspect ration of any other images in a conversion.

thanks both, but this is concerning cover image only.

I wonder about the images inside book, which *all* are stretched during conversion.
The command I pasted above is from the manual (to conserve aspect ratio) but the manual fails to say where to add command when using GUI mode.

Several places on the internet mention this cover image issue, which easily can be fixed but none explains how the keep aspect ratio of images, a problem many have (anyone who wants to convert a file with images).

In General
Image stretching may be your devices doing if the image is not constrained in the CSS (has a height or width: 100%).
Also, your selected (device) output profile has affect on size

Cover:
Preferences: Conversion: Output options: EPUB(tab): tick Preserve cover aspect
