How to autofit images on Calibre

dafkah · 06-12-2013, 04:21 PM

Hi wonderful people! I'm new here. I'm sure the information is here somewhere, I just haven't found it yet.

I have portrait (not landscape) images I wish to be visible on the entire screen of all devices. I understand there's some coding I can add to force it to fit the screen. Something like "maxheight = 100%"?

What's the exact code and where do I type it in?

Currently, I take a word doc, convert it to html, zip the html file, use Calibre to convert the zip file to ePub, but either the images cut off at the bottom and the rest of the image appears at the top of the next page, or the image is too wide and gets cut off on the side (though proportionally it looks right).

What code do I need to add and where do I type it in?

Thanks so much!

Thanks for repositioning my post! Any ideas on how to format an image in Calibre so that the image takes up the whole page without being cut off?

If the document is all images maybe converting to to CBZ would be a better solution. Or converting to CBZ then to ePub?

For conversion straight to ePub I'm not sure how. You may be able to do it in Sigil by modifying the code calibre uses to wrap images for the cover page. I grabbed the below example from a random book from my library.

Code:

    <svg xmlns="http://www.w3.org/2000/svg" height="100%" preserveAspectRatio="none" version="1.1" viewBox="0 0 563 751" width="100%" xmlns:xlink="http://www.w3.org/1999/xlink">       <image height="751" width="563" xlink:href="../Images/cover.jpeg"></image>
     </svg>

The above does not preserve the aspect ratio.

The code below does preserve the aspect ratio.

Code:

<svg xmlns="http://www.w3.org/2000/svg" height="100%" preserveAspectRatio="xMidYMid meet" version="1.1" viewBox="0 0 563 751" width="100%" xmlns:xlink="http://www.w3.org/1999/xlink">       <image height="751" width="563" xlink:href="../Images/cover1.jpeg"></image>
     </svg>

Maybe someone will chime in with real experience.

Good Luck.
