FTGL 1.3b4
November 13 2001
TODO:
- namespace ftgl or gltt?
- make a decision about what units to use for font metrics!!!
FUTURE:
- select face ie italic, bold etc
- Multiple sizes
- Optimise performance and mem usage.
- gl/glu errors
- check and confirm the glPixelStore stuff. Data Alignment. Tightly
packed at the moment.
- Use the Freetype Cache mechanism. FTC_xxx
- Vertical formats
- Multiple Masters
- String Cache or string chunks
- Provide an interface to access the point data for outlines and
polygon meshes. Part way there with new vectoriser.
- Have a look at improving the algorthm for making curves. Maybe a
distance metric might be the way to go so that rather than having
5 polylines (0.2 step) for every curve, adjust the fineness for
the length of the curve. But then you should also test the angle
of the tangents as well.
BUGS:
- Advance/Kerning is screwed up for really small point sizes eg 2 point.
This is because I'm trying to use FT_Vector which is integer based.
I will probably have to make my own struct with floats.
- The texture co-ords in the Texture Font may be wrong for non
scalable fonts.
- There is an inconsistancy in the way the global bounding box is
stored in Freetype. It is supposed to be in font units but in some
cases it is in 16.16 format. I have implemented a work around but
hopefully the freetype guys will sort this.
- The initial position of a glyph is different for (outline, polygon)
& (bitmap, pixmap, texture) See '!' in G.Lanois demo
- FTVectoriser seems to position some points incorrectly. confusing
line point with control point at start or end????
