GXTY 08 - QuickDrawGX Fonts (1-May-95)
Q I have certain fonts which cause the driver to fail when they are
installed in the system while my spool file is being processed. If I remove
these fonts from the system, the problem disappears. It isn't clear whether all
of the necessary font information is contained in the spool file once it is
generated. If it is, why does it appear that QuickDrawGX looks for the fonts
when processing the spool file? Where can I learn about how the QuickDrawGX
font mechanism works during page generation and printing?
A PDDs (page description documents) are transportable and include all the
information necessary to image a document. Spool files are not intended to be
transportable and assume that the fonts designated in the file continue to be
available. For efficiency's sake, they don't spool the fonts, which explains
why the fonts are being accessed.
You can learn more about printing from Inside Macintosh: QuickDraw GX
Printing Extensions and Drivers , both on the December 94 Dev CD and in
print from Addison Wesley. You may also find a number of articles in
develop which could help you to learn more about the QuickDraw GX font
mechanism.
