This directory contains a test suite and some examples.
X
All of the files beginning with a capital letter are meant to be
run through plas with the -v option, ie:
plas -v < TEST_align | ?pen scale=?
X
Demo files are meant to show what sort of nice pictures you can make
with vplot. The "demo" files (note lowercase) are meant to be read directly,
ie:
X?pen demo_pacific.v
The lower-case demo files will not be included in some versions of the
distribution. (If size is of importance.)
You can try out several of the demo files at once by:
X?pen par=parfile
X
Each of the files beginning "TEST" is meant to test something.
It should be pretty obvious if something is wrong. Some of them
will print out text on your screen pointing out what to look for.
X(If none of them do, then you've got a problem with your dev.message
routine.) The csh "All_tests" will run through all the tests, one by
one. The argument to All_tests is the name of the vplot filter you
want to use.
X
Programs:
X
The program Font.c produces pldb-format files which display the contents
of a font. For each glyph in a font the corresponding glyph in font 0
is shown (small), along with the glyph's index. A ``?'' in a box is
a special error symbol which indicates that the desired glyph is not
defined. This error glyph is glyph number 30 in font 0.
X
The program rastest.c must be linked with -lvplot, and the output of it
can be piped into any pen filter. It produces an interesting color raster
moire pattern (it may take a while to come out if you're using genraster).
This program also serves as an example of how to use vplotlib from a C program.
X
Other example C and FORTRAN programs are:
X
ellips.f, libvplot_example.c, polytest.c
X
You'll have to edit the makefile to call the appropriate pen filter.
X
X
The programs here are bad examples in that they implicitly use hardwired
magic numbers, without basing them off of the defined values in vplot.h.
The metafiles in this directory are also in raw integer Vplot units, not
inches or centimeters. These, however, are easy to convert using plas (if
needed) and pldb -i.
