I desperately need to do plots where the screen contains exactly
three kinds of objects:
- dot (one pixel)
- line (specified as (x1, y1, x2, y2)
- text (specified as (x, y), font, pointsize and string).
I know no postscript as of right now. Is there a sugar-coated
library whereby I can readily do this? I can readily imagine a
library where I would issue calls in a certain coordinate system
(which I have to figure out) and nice postscript files would get
written.
C or Pascal are fine by me; I can also hand-translate fortran.
Thanks!

# include <stdio.h>
void emit_trivial_postscript()
{
printf("\nP.S. What's the capital of Mali?\n");
}
Compile this, and put the result into /usr/lib/libetp.a. Always glad
to help. :-)

I can readily imagine a > library where I would issue calls in a certain coordinate system There is a firm here in Austin called Barton Creek Software. 2222 Western Trails, Suite 106 Austin, Tx. 78745 512-441-8354 This company has just released an ANSI C postscript library. It sells for about $149.00 I think, and comes with source. I was a beta tester for it, and had a lot of input. It is very nice. It consists of a collection of routines, that emit postscript code. There is a very complete set of ascii printing code, a full graphics and postscript primative library, and some nice high level stuff. There is also an MS-DOS format file downloader. It uses a user supplied routine for it's output. a sample of some of the calls. ps_arcto Draw an arc ps_circle Draw a circle PS_curveto Draw a Bexier curve ps_ellipse Draw an elipse ps_fill fill the current path ps_line Draw line ps_poly Draw a polygon ps_polycurve Draw multiple curves (one of my suggestions) etc. etc. There are well over 120 functions supplied.

They are available now by anonymous ftp from ncifcrf.gov in pub/delila. The program is in dops.p.Z and the demo file is in dops.demo.Z. You will have to make a routine to modify font and pointsize on the fly. Tom Schneider National Cancer Institute Laboratory of Mathematical Biology Frederick, Maryland 21702-1201 toms@ncifcrf.gov

GNU has a set of graphics utilities available via anonymous ftp from
qed.rice.edu as /pub/graphics.tar.Z. Along with replacements for the
Unix utilities plot and graph, it contains a very good postscript
library in C to draw circles, lines, text, dots, etc., etc. As a
bonus, any PS file generated with these utilities is editable with
idraw!
