Not really a python guy myself either,
First of all, thanks a lot for responding to this email.
but I know enough python & freetype to be trusted with commit access to freetype-py (I think I wrote about half of their bundled examples. A few years ago when I decided I wanted to learn pycairo, I rewrote all their existing examples from PIL+numpy to pycairo... so doubling the number) - that's the "x.freetype.x" part you are using below. So I read some freetype-py issues filed too
I extracted your codes from freetype-py git and tried those with the default font. However with devanaragi fonts the rending on the surface was shifted upwards, this the glyphs displayed were cut in the middle horizontally. Could that be due to different font parameters?
.
If I remember correctly, pygame bundles their own rather old freetype-py fork in their "pygame.freetype." part, and possibly also a very old private libfreetype too. So problems you experienced might just be because of using old code (as in, freetype 2.5 era...).
I reviewed the pygame source and it seems their "freetype" interface is missing harfbuzz objects internally, thus, when pygame-freetype passes requests to FT, the FT-Face do not have valid hb_* object pointers. I am thinking of making a change in pygame interface. Do you think it will fly and doable?
You might want to check versions of both.
That path /usr/share/fonts/truetype/Sarai/Sarai.ttf looks linux - Debian or Ubuntu? They ship some fonts of questionable quality...
Yes, I had picked the front from this system location. Is there any repo. that hosts many fonts for free?
Lastly, shameless plug: Font Validator is your friend...
I shall try that.
I collects FontVal reports from all shipped fonts on fedora and ubuntu from time to time, specifically just the rasterizer/ hinting instructions part as FontVal's testing. I think the report for this font (just the hinting instructions part) might be filed under https://github.com/HinTak/FontVal-Tests-at-10pt/ already, under the Ubuntu or the fedora branch.
