[GUI Plugin] Generate Cover

Any of the google fonts like Open Sans or Noto Serif will have the font styles issue if you wanted to play with it. It's most noticeable when you select an extra bold serif font and the preview returns a sans-serif normal font.

Don't roll back. What you can do instead is install a portable version of the calibre 7 and use that with this plugin and the current version with everything else.

I shall install a portable version until fixed, thanks.

So I have been using the Generate Cover extension. Very handy,. But all of a sudden I have been getting the following error. calibre, version 8.4.0

This is on every book I try to use generate cover on. I have tried uninstalling it, restarting calibre, and reinstalling the extension and still have the issue. Any ideas?

Thanks so much. That did the trick.

I have been having the weirdest issue with SVG on Generate Cover...

Some background first. I downloaded Kuzzzma's templates a while ago. I found them nice, but not quite what I was looking for. I decided to create my own.

Inspired by Kuzzzma's AO3 variants of those templates, I decided to create separate models for each major source of downloaded fiction I use -- AO3, Fanfiction.net, TTHfanfic etc, each one with a different basic color but following the same layout. I use the latest version of Inkscape, by the way.

It all went well at first. I obtained SVG logos for some of the sites, and I could embed them fine as editable objects. For a few of the sites, I could only manage to find a PNG logo (with transparency), and those embedded fine too.
I had a minor hiccup with one site which lacked a proper logo so I just used text in a fancy font; the SVG worked fine in Inkscape, Windows explorer, browsers etc. but the text got all out of alignment in Generate Cover; that was solved by converting the text into separate glyphs (and then it occurred to me that making the svg dependent on a font was a bad idea, so I converted it to curves). In fact, it all seemed to be going fine... until Patreon.
I can't fathom why, but Generate Cover persists on placing a back rectangle over the Patreon logo. I tried using SVG, PNG and even GIF versions of the logo; it made no difference. I thought that the SVG might be corrupted; I copied one of the templates I had made for other sites (and which were working) and just replaced the logo. Same thing. They render fine on browser, just not on Generate Cover.

I know this is just as far from serious as an issue can be; There is an easy workaround, I can always save the template as PNG instead of SVG. But the little OCD inside my mind is frustrated wondering what the heck could possibly be causing this behavior.

Has there been any word on the fonts issue with this plugin on the latest version of Calibre? I looked into the suggestion to install a portable version of Calibre 7 to use, but I'm on a Mac and it looks like the portable version is just for Windows. Any suggestions for Mac other than rolling everything back? Hoping this gets fixed in future Calibre updates. It's so frustrating.

Quick follow-up to my previous post. I found a way to sandbox Calibre 7 and tested it out with the Generate Cover plugin and that didn't fix the issue for me. I can confirm that the issue is with fonts with different weights. It will default to a generic sans serif font if you choose any font (serif or sans serif) with a font weight specified.

That is an issue with calibre that's been fixed. So you will have to update to the next calibre version 8 in order to get this fix. So when a version of calibre past 8.13 is released, you'll want to update.

That's great news!

If I'd known that, I wouldn't have bothered with my current hack. But in case anyone wants to get this working immediately (with the latest version of Calibre), you can do it by editing the internal name table for the font you want to use. You just have to remove the weight label from the name in the following namerecords:
nameID="1" platformID="3"
nameID="4" platformID="3"

nameID="6" platformID="3"

That is way too much work for anyone able to run the latest calibre. All you have to do is wait until either this Friday or the next Friday and problem solved.
