(c) 1992, 1993 H. Werntges HP2XX release 3.1.2 93/04/17
===================
Files in ./sources:
-----------------------
README This file
makefile A symbolic link to ../makes/generic.mak
bresnham.c Implementation of Bresenham algorithm (for line rasterization)
chardraw.c Code for drawing ASCII characters
getopt.c from GNU getopt, slightly modified -- don't re-distribute!
getopt1.c from GNU getopt -- don't re-distribute, use original!
hp2xx.c High-level routines for hp2xx
hpgl.c HP-GL parser etc.
no_prev.c A dummy previewer
picbuf.c Code for raster ops (vector-to-internal-bitmap)
to_amiga.c AMIGA previewer
to_atari.c ATARI previewer
to_dj_gr.c DOS full-screen (S)VGA previewer, based on DJ Delorie's gr lib
to_eps.c Output converter for EPS (Encapsulated PostScript)
to_ilbm.c AMIGA only: IFF-InterLeave BitMap converter
to_img.c Output converter for IMF (DR's Image format)
to_mf.c Output converter for Metafont sources
to_pac.c Output converter for ATARI PAC format (unsupported)
to_pbm.c Output converter for PBM (Portable BitMap) format
to_pcl.c Output converter for HP PLC Level 3 (and some Deskjet extras)
to_pcx.c Output converter for Paintbrush PCX format
to_pic.c Output converter for ATARI PIC format (unsupported)
to_pm.c OS/2 PM previewer (unsupported -- stderr output is lost yet)
to_sunvw.c SunView previewer (unsupported -- outdated)
to_uis.c VAX-VMS UIS previewer
to_vga.c DOS full-screen VGA previewer
to_x11.c X11 previewer
bresnham.h Contains a basic struct -- needed by almost all C sources
chardraw.h Header for character drawing.
charset0.h Definition of built-in font / character set 0
getopt.h from GNU getopt -- don't re-distribute, use original!
hp2xx.h Central to almost all C sources
iff.h AMIGA only: for IFF-InterLeave BitMap converter
ilbm.h AMIGA only: for IFF-InterLeave BitMap converter
x11.h Some X11 extras
NOTE about unsupported formats:
------------------------------
o to_dj_gr.c works fine on 386 and 486 CPUs, but I'd rather replace it
by code both applicable to DOS and OS/2, and that will be
emx.
o to_pm.c is my first OS/2 PM project. It seems to work nicely, with
the exception that I don't know how to re-direct hp2xx's
diag output (to stderr or log file) into a second window
WITHOUT significant changes in the sources.
If you know a simple way -- please tell me
(I'm aware of pmprtf -- this come close but won't do it).
o to_pic.c The PIC format was mainly used by ATARI programs like
Signum. I consider it outdated. Try to work with IMG.
o to_pac.c Similar to PIC (compressed version of PIC), used e. g.
by STaD.
For installation, get a suitable makefile from ../makes and follow
intructions in ../makes/README.
For details of operation, see ../doc/hp2xxinf.tex (hp2xx.texinfo).
Optionally test hp2xx with HP-GL files provided in ../hp-tests.
E. g., run
% hp2xx -h100 -w100 ../hp-tests/ascii.hp
(This should result in a graphical display of the available
character set 0.)
Enjoy!
