#!Rdxgft DXGetFont #!N #!N Function #!N #!N Returns a Group representing
the named font. #!N #!N Syntax #!N #!F-adobe-times-bold-r-normal--18* #include <dx/dx.h> Object
DXGetFont(char *name, float *ascent, float *descent) #!EF #!N #!N Functional Details
#!N #!N The Group has as many members as there are
characters in the named font ( #!F-adobe-times-bold-r-normal--18* name #!EF ). Typically,
the returned font is passed to #!F-adobe-times-bold-r-normal--18* DXGeometricText #!EF to construct
a text Object from a given string. Alternatively, individual characters can
be extracted using #!F-adobe-times-bold-r-normal--18* DXGetEnumeratedMember #!EF . The member number is
the same as the ASCII character code. #!N #!N The font
has an overall height of 1. If #!F-adobe-times-bold-r-normal--18* ascent #!EF is
not #!F-adobe-times-bold-r-normal--18* NULL #!EF , the portion of the overall height
above the baseline is returned in #!F-adobe-times-bold-r-normal--18* *ascent #!EF . If
#!F-adobe-times-bold-r-normal--18* descent #!EF is not #!F-adobe-times-bold-r-normal--18* NULL #!EF , the portion
of the overall height below the baseline is returned in #!F-adobe-times-bold-r-normal--18*
*descent #!EF . The sum of the ascent and the descent
is the overall height 1. #!N #!N This routine checks the
environment variables DXFONTS, DXEXECROOT, and DXROOT for directories to search for
fonts. The routine also checks in /usr/lpp/dx and in the subdirectory
#!F-adobe-times-bold-r-normal--18* fonts #!EF of each of these directories. #!N #!N Return
Value #!N #!N Returns the font or returns #!F-adobe-times-bold-r-normal--18* NULL #!EF
and sets an error code. #!N #!N See Also #!N #!N
