It fixed the problem I had with Kurinto Text, so I decided to do the same with all my fonts and I haven't noticed the problem since.
It's easy to do in FontForge:
- Go to the Font Information window, go to the General section, take the Ascent value and then go to the Metrics tab of the OS/2 section and input it into the Win Ascent, Typo Ascent, and HHead Ascent fields.
- Do the same with the General section's Decent value with the Metrics tab's Win, Typo, and HHead Descent fields.
- Finally, set the Metrics tab's Typo Line Gap and HHead Line Gap fields to 0.
Or if you have Python, you can install gftools and do the same with this command:
Code:
gftools fix-vertical-metrics -a ASCENT -d -DESCENT -l 0 FontName-Regular.ttf
Substituting the appropriate values for ASCENT, DESCENT, and Font Name.
For font families, use the Ascent and Descent values from the Regular font face with the bold, italic, and bolditalic versions to make sure everything stays consistent. |
I just tried this and it still had the problem. It's when you have the line-height small enough. I even tried some Kobo fonts and other fonts I have installed and they all showed the same thing.
