SAS/GRAPH includes methods
of storing rendered versions of Bitstream fonts, along with three
graphics options to control how the fonts are rendered.
When your graphics
output uses one of the Bitstream fonts that are provided with
SAS/GRAPH,
SAS/GRAPH must process information contained
in corresponding FONTS catalog entries to determine how to draw characters
of the specified size and typeface. The process of calculating the
character shapes and sizes is known as
rendering the font. Bitstream fonts that are available with
SAS/GRAPH include the Century, Swiss, and
Zapf font families.
SAS/GRAPH can store rendered versions of the Bitstream fonts
in memory or in special SAS files. Using these rendered versions of
the fonts can provide a speed improvement when characters of the same
size and style are used again during the SAS session.
SAS/GRAPH can read the rendered version of
the characters from memory or from the rendered font file instead
of performing the rendering calculations each time the characters
are used. If you store the rendered fonts in files in a permanent
SAS data set,
SAS/GRAPH
can use the rendered font files again in subsequent SAS sessions.
Note: Because the rendered font
files use a special utility member type, they do not appear in the
list of library members that is displayed in the
DIRECTORY window.
