NAME

libhersheyfont - Hershey vector fonts library

SYNOPSIS

#include <hersheyfont.h>

struct hershey_font *hershey_font_load(const char * fontname );
struct hershey_font *hershey_jhf_font_load(const char * jhffile );

struct hershey_glyph *hershey_font_glyph(struct hershey_font * hf , unsigned char c );

void hershey_font_free(struct hershey_font * hf );

DESCRIPTION

The Hershey fonts are a collection of vector fonts developed circa 1967 by Dr. A. V. Hershey. libhersheyfont provides C routines to load and process .jhf format Hershey font files.

A Hershey font may be loaded with herhsey_font_load () or herhsey_font_jhf_load (), either of which returns a pointer to a newly allocated struct hershey_font . This structure should be freed after use with a call to herhsey_font_free ().

The glyph line segment data for each ASCII character may be accessed with herhsey_font_glyph ().

See the hersheyfont.h header file for the details of the structure members.

FONTS

hershey_font_load ()’s fontname parameter must be the name of a system-installed Hershey font. The Hershey fonts likely to be installed are:

astrology , cursive , cyrillic , futural , futuram , gothgbt , gothgrt , gothiceng , gothicger , gothicita , gothitt , greekc , greek , greeks , japanese , markers , mathlow , mathupp , meteorology , music , rowmand , rowmans , rowmant , scriptc , scripts , symbolic , timesg , timesib , timesi , timesrb , timesr

herhsey_font_jhf_load ()’s jhffile parameter must be the filename of a Hershey font .jhf file.

ENVIRONMENT VARIABLE

HERSHEY_FONTS_DIR

The directory in which herhsey_font_load () expects to find .jhf font files (The default directory is likely /usr/share/hershey-fonts/ or /usr/local/share/hershey-fonts/ depending on the build configuration).

EXAMPLE

See hershey-font-example.c for a complete working example program, including code to parse the glyph data. Likely location:
/usr/share/doc/libhersheyfont/examples/hershey-font-example.c
