Read all the other README files which are in most directories
before attempting "make install".
X
You may also want to look at all the stuff in the directory ./Documentation.
In particular, you should read the copyright notice in vplot.mn.
X
Here are the files you should have:
X
Documentation - just what it says
X
Hershey - stuff for converting the Hershey fonts as distributed to something
X Vplot can use.
X
Hershey_Fonts - the actual Hershey Fonts themselves. These are NOT themselves
X part of Vplot, but this directory may be included as a
X convenience. If you don't have this directory, you'll have
X to track down your own copy of the Hershey Fonts. Vplot is
X useable without them, but you'll only have 1 boring font.
X
Makefile - just spawns off all the other makefiles in the subdirectories.
X
README - this file
X
filters - the source for the vplot filters.
X
lvplot - the source for the lvplot library.
X
util - the source for some vplot utility programs.
X

X##########################################################################
X
Notes for the "long" version of the distribution:
X
I have tried to make the "makefile" in this directory such that
X"make install" will do EVERYTHING.
X
Remember, you WILL have to get ALL the site-dependent parameters,
include files, makefile defines, etc, etc, all set FIRST.
X(For the most part, this just means doing the stuff in the README
file in "filters". The make install should probably handle everything
else.)
X
After you THINK you've got that all right, if you're brave, you can
try running this make. It worked on our system, at least...
X
X##########################################################################
X
Notes for the "short" version (if you don't have the Hershey_Fonts directory,
you've got the short version):
X
You will be missing some "demo" files in ./filters/Tests, no big deal.
X
You will either have to get a copy of the Hershey fonts OR edit
X./filters/include/font_definitions.h before any of the pen filters
will compile.
X
The device-dependent code for various filters will be distributed
separately. Simply get the appropriate device-dependent library,
stick it in ./filters, re-run MakeMake, do make, and you should
be in business. Here are the various devices so far (some of them
may not be distributed for a while if I think there's a chance of
getting them improved first):
X
Masscomp (gps),
Sun (2: suntools + NeWS),
XX,
Virtual (2: Generic Raster + Vplot "Editor"),
Tek (2: 401X and 410X),
Envision (Lear Siegler),
Regis,
Imagen,
PostScript,
RasterTek

On a color device colors of bars should match with their labels.

If not, then the default colors for the device are wrong.
z
Monochrome devices should display a grey scale, with the background color
z
at the bottom and the opposite of it at the top.
z
The vertical stripe should be drawn in the background color.

Box A and Box B at the top should both look exactly the same,

except that the blue line should disappear behind Box A and not Box B.

If any of the boxes are shaded with something besides the background color

X(possibly making it so you can't read the text except in Box B)

then your device driver does not do proper fill for color 0. (serious bug)
