I just updated to the last version of the plugin and there seems to be some kind of bug with the font rendering. I had been using Blambot's
"ACME Secret Agent" font for some of my covers, but now it no longer works.
I can still select the font from the drop-down, but the text renders in Arial. However the
"Ale and Wenches" font renders just fine.
Just for the fun of it I tried uninstalling the TrueType version of the font and installing the OpenType version, but it made no difference. I have been using the affected font frequently in other programs and I have verified that it continues to render correctly elsewhere.
I am running Calibre v2.57.1 on Windows 10 with Generate Cover v1.5.18.
I was also able to reproduce the issue on a newly-installed Windows 7 virtual machine using a fresh copy of Calibre v2.56 with Generate Cover v1.5.18 and a virgin library with no books besides the "Quick Start Guide" and no additional plugins installed. The behaviour was the same, except that instead of rendering in Arial it rendered in a Serif font that I was unable to identify (see attached screenshot).
It's not a major problem, but it
is rather annoying. If there is any additional information I could provide or tests that I could do to aid in debugging, I'd be happy to assist in any way I can.
