Question about Text Path

[Harper, Brad]

Aaiii! Please help.

I've been trying to write a high-level device driver for Ghostscript
8.61. In particular I've been working on the *_text_begin() procedure
trying to extract text coordinates from the 'path' argument. [I used the
gdevtrac.c trace driver as a starting point.]

Can someone explain the preferred way to get the text string's x/y
coordinates? It should be easier than this. Other drivers in the source
distribution seem just as obtuse.

Also, what's the easiest method to recover the font size?

Thanks.
