font rendering issues

[Richard Jones]

Hi all,

If anyone has a chance I'd appreciate if you could pull the latest
pyglet repos and try out examples/font_comparison.py - you will
probably need to obtain some of the fonts, but most importantly I'm
interested in whether Consolas renders correctly on various systems.
On my Lion system it does not. You can see obvious rendering errors if
you compare the Consolas render to the Menlo render in the attached
images.

The question really is whether this is a problem on OS X only...

Seems to be related to this bug which only affects CTFongGetBoundingRectsForGlyphs on Mac OS X Lion:

The example renders fine on Snow Leopard, but Lion is apparently reporting the wrong dimensions for glyphs in some monospaced fonts.

Nice detective work, thanks. I guess we'll have to incorporate the
code linked from that issue to work around it :-(

Ah, there's the problem -- they outsourced it to
Chinese software developers!

Fedora 17. Seems fine.

 Wait. The rendering is wrong. Consolas is monospaced, but def lines are not properly aligned vertically.

It might be that there is no Consolas and another font is substituted. Is it possible to detect if font is available with pyglet?
