This directory contains all the Vplot fonts.
The fonts are in three forms:
X
X.vplot_fonts : This is the human-editable form generated by the program
X hertovplot.c. Its format is documented in the beginning
X of the program makefont.c
X
X.bin : A binary form of the font, which can be loaded at
X execute time on demand by gentext.c. (They aren't
X loaded unless the user accesses the font.)
X
X.include: An ``include'' file form of the font, which can be
X #include'd into gentext.c at compile time. This way
X gentext.c won't have to read the font off disk at
X runtime if the user uses it.
X
Which fonts are included and which are loaded at compile time is set
in the include file font_definitions.h in the .../vplot/include
directory. It should be obvious from the file how to modify it.
If you have more or fewer fonts than we do here, you will also have to edit
the makefile in this directory so that it knows what fonts you have.
X
Generally, very commonly used fonts should be included, and all the
others should be loaded at runtime as needed. At SEP we have only
fonts 0, 1, and 3 (pen, roman simplex, and roman complex) compiled in.
Since the fonts are quite large, compiling in each font takes a
large amount of compile time. (To say nothing of making lint virtually
unuseable.)
X
Please read "vplottext.mn" and the Makefile in this directory to
find out how to obtain the necessary .vplot_font files. "pen.vplot_font"
is NOT a Hershey font and is an official part of Vplot. It is not beautiful,
but it is complete and efficient.
