How to add image logo to the header when converting to pdf

prkumar · 05-21-2018, 10:27 AM

Calibre does a very good job of converting ePUB to pdf. One thing I am still not able to achieve is to add an image (like a logo) to the header.
Is it supported?

I tried something like:
--pdf-header-template "<table><tr><td width='30%'><img src='EPUB/img/logo.png'/></td><td width='40%' align='center'>Some Title</td><td width='30%' align='right'>Jan 21, 2018</td></tr></table>"

Tried various path in src attribute if img tag but to no avail.

Is there any plan to add this in case it is not supported yet?

Thanks

You can use any arbitrary HTML you like, however you cannot use paths, instead use a data URL (google how to create and use them).

Thanks for your reply Kovid.
But it did not work with dataURL as well.

I used following img tag
<img src='data:image/gif;base64,R0lGODlhEAAQAMQAAORHHOVSKudfOulrSOp3WOy DZu6QdvCchPGolfO0o/XBs/fNwfjZ0frl3/zy7////wAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAACH5BAkAABAALAAAAAAQABAAAAVVICSOZGlCQ AosJ6mu7fiyZeKqNKToQGDsM8hBADgUXoGAiqhSvp5QAnQKGIg UhwFUYLCVDFCrKUE1lBavAViFIDlTImbKC5Gm2hB0SlBCBMQiB 0UjIQA7'/>

Please let me know if I am missing anything.
