Feedback on the attached test version would be appreciated - I will release this as 2.5.0 once the poor translators have stopped swearing at me for making so many changes - thanks all who contribute to that!

This has occupied most of my weekend - if it really does float your boat as I hope it will then please don't forget to donate

Spanish translation complete! It's always a pleasure to help with translations.

Hello..
I just came back & started using calibre again after 2 years. Last calibre version I used was 8.9.0. After updating both calibre & the plugins today, I found something odd with the Generate Cover plugin.
Many of the fonts I have used before are not working anymore! For example, I have mostly used a font called Eras ITC. The last time I used in Dec 2024, it worked flawlessly. But now, it's not working anymore. I can choose the font from the dropdown menu, but it's not rendering correctly. I don't know whether this is because of changes in Calibre or changes in the plugin itself.
I am attaching the .ttf font files below so that you can notice the difference when rendering the font in the plugin vs rendering it in a word file.
Please fix this issue if possible.

Look a few pages back for the issues people had with calibre and fonts. It is nothing to do with this plugin, it is issues with Qt6 that calibre updated to. There was some supposed workaround that could be done proposed in one post but I didn’t personally read the details, its not a plugin issue.

Ohh.. thank you for the advice.
I did look back a few pages & it seems like it's stalled now. I found your thread you opened in the dev section & Kovid replied with a bug report he submitted to Qt. Looks like that bug report got closed as "fixed", but I don't see any change.. it's still not working me in the latest version of Calbre 9.17

I also found slimcat's workaround but unfortunately it didn't work for me either.

Edit: Upon further investigating, it looks like the Qt issue probably got solved (?) because if I choose my font for the calibre interface, it works.. the text font inside any book also works with my font.. only place it doesn't work is inside the Generate Cover plugin!!
@kiwidude, Can you please take a look again with my above font?

@version365 - I can see that this is perhaps a different sort of font issue. The problem is that currently the plugin uses a calibre function to return the list of fonts. That function is not returning what I actually need in this case - it coincidentally works for "most" fonts but not for ones like this. That is why it lists the individual fonts of "Eras Bold ITC" instead of the font family which is "Eras ITC" that is needed to actually render correctly.

I have an alternative means of populating the font family dropdown which I have tested locally and works ok for me but it has me wondering why I never used it originally when the plugin was written 15 years ago. I've left a message for Kovid to see if he can tell me any downside of this other approach is, will see what he says. One thing that comes to mind is perhaps the calibre approach allows for fonts to be located in places other than the system fonts for instance - but I would rather something that just works with that limitation than something that doesnt.

Release Notes:
https://github.com/kiwidude68/calibr...te_cover-2.5.0

In the absence of any negative reports from those who kindly tried the test version here is the official 2.5.0 release. See my post on the previous page for more detail about it.

Thank you Kovid for confirming my thoughts. I have included the change to the font dropdown with this release.

It is possible you may have "wrong" font family names in your saved settings (more likely you didn't use them as they didn't work) so you will need to select the new font variation if that happens to you.

Not all translations have been updated yet but they can be put in the next release.

I will at some point update the help documentation and examples/screenshots, on the never ending TODO list.
