RE: [Devel] Rendering fonts into PCL downloadable font format?

[Keil Claudia]

Hi Rich,

the guide to create PCL truetype softfonts is the PCL 5 Printer Language
Technical Reference Maunal.
I don't know other sources or specs.

What do you mean with "the necessary command for substitution" in the
PCL-table ?
You are right the most TTF's doesn't contain a PCL table.
But the most values in the PCL table are only relevant for font selection
via the PCL font selection mechanism.
You don't need them if you select the font by ID.
In contrast to this an important value of the PCL table is the pitch, which
directly affects the space width. 
You can use instead the horizontal advance of the space in FUnits.
(FT_Glyph_Metrics.horiAdvance).

regards

Claudia

Actually, I have pretty much EVERY question.  I've hunted in vain for specs
on the file format for downloadable fonts for PCL, for instance.  We want to
integrate it into our code such that if someone chooses a TTF font using our
internal PCL output driver, it would automatically convert and download it
if the TTF font doesn't contain the PCL table with the necessary print
command for substitution (Some do, but we've found very few so far).

I'd be thrilled if I could get the downloadable font specs (or a pointer to
where I could find them), and even moreso if I could get a general
overview/tips on rendering TTF fonts into the proper format to match those
specs, or even some code snippets.

Yes, I'am using freetype to create PCL softfonts.
It works well. Have you any questions ?

We are using freetype here to a very limited extent, at present just reading
font metrics from TTF files.  I am aware that a great deal of the freetype
library is devoted to actually rendering those fonts.  My question is this:

Is there anyone out there using freetype to "render" TrueType fonts into a
format that can be downloaded to a PCL printer?

Thanks in advance for your reply,
