X.SH NAME
vplot - definition of the vplot graphics metalanguage
X.SH INTRODUCTION
Vplot is a graphical meta-language that is interpreted by the
X.B pen
filters to produce plotted images
in a device-independent way
on many different graphics terminals
and hard copy devices.
New devices can readily be supported.
Unfortunately,
X.B vplot
has only a primitive interactive capability.
The reason for writing your plots in a device-independent
intermediate plot language such as
X.B vplot
is to make your plot programs portable and long lasting.
X.PP
Vplot originally stood for `vector plot',
but this name is now insufficient
because vplot supports not only vectors,
but also filled areas (either raster patterns or hatched),
text (Hershey fonts),
and raster images
X(including grey-scale dithered ones on monochrome devices such as laser printers).

X.SH COORDINATE SYSTEMS
Vplot fits the largest 3-high by 4-wide rectangle
X(or whatever ratio is defined by SCREENRATIO in vplot.h)
onto the device's screen that it can. The rectangle is left and bottom justified.
Clipping is not done to the edge of this rectangle, but to the edge of
the device's screen. For convenience, from here on in the documentation I
will consider the
X3 by 4 rectangle inscribed inside the device's screen to BE the device's screen
for the purposes of describing Vplot's coordinate system.
X
Vplot coordinates can either be measured in integer vplot units (the actual
integer numbers that go into the metafile) or as real inches. How many integer
units there are per inch for various sorts of Vplot primitives is defined in
vplot.h. RPERIN is the number of integer vplot units per inch for most things.
Unfortunately, in order to be backwards compatible we have to measure some
primitives in different units: TXPERIN gives the number of text-height units
per inch, and FATPERIN gives the number of line-fatness-width units per inch.
X(HATCHPERIN is only used by libvplot, not vplot itself.)
At Stanford, RPERIN=600, FATPERIN=200, and TXPERIN=33. These are not particularly
convenient numbers, and new sites installing Vplot from scratch might consider
selecting more reasonable values for all of these. (In theory, all you
should have to do is change the definitions in vplot.h, update the
documentation, and recompile everything in sight.)
Whenever any of these ``magic numbers'' are referred to in code, they should
be ``#define''d by vplot.h.
X
Two different scaling systems are possible, ``relative'' and ``absolute''.
The so-called ``real inches'' in Vplot can either correspond to absolute
inches on your device's screen (size=absolute),
or can scale with the size of the screen (size=relative).
How many inches tall the screen is considered to be unfortunately depends on
the ``plot style'', which is defined next.
X
Two different coordinate systems are possible, ``standard'' and ``rotated''.
X(This is called the ``plot style''.) The plot style can be set with the
vplot `S' command, set from the command line, set from the environment,
or allowed to default, with that order of precedence.
X
Standard Style: The origin is in the lower left hand corner, with
the X axis horizontal and the Y axis vertical.
If size=relative, the plot is scaled so that the screen is considered to be
X10.24 (STANDARD_HEIGHT in vplot.h) inches tall. That is, if you move to
the Vplot coordinate (in inches) of (x=0.,y=10.24), you will be at the top
left corner of the screen no matter how big or small your device's screen
actually is.
X
Rotated Style: Plot is scaled so that the screen is considered to be
X7.5 inches tall. The origin is in the upper left hand corner, with the
XX axis vertical running down the screen and the Y axis horizontal.
If size=relative, the plot is scaled so that the screen is considered to be
X7.5 (ROTATED_HEIGHT in vplot.h) inches tall. That is, if you move to the
Vplot coordinate (in inches) of (x=7.5,y=0.) you will be at the bottom
left corner of the screen no matter how big or small your device's screen
actually is.
X
X.SH DESCRIPTION
The following list constitutes the plot commands for
the various plotting programs.
The commands are universal in the sense that they are properly
read in and appropriately used or ignored.
The commands are specified by a literal one byte command
character followed by zero or more half-word (2 byte) integers
X(sometimes characters or bytes if so stated in the text).
X.PP
The program ``pldb'' converts the binary Vplot format described here into
a human-readable ASCII one. Pldb-format Vplot follows the documentation here
closely. Commas show where newlines occur in `pldb' format vplot that are not
shown as newlines here.
X.PP
X.SH COMMANDS
X.TP
X.B e
X.B erase
the screen and start a new plot.
All plot frames begin with an erase.
X(The ``erase'' pen filter option can be used to add an erase as the very
first thing in an input plot file, but will only do so if the plot file
doesn't already have an initial erase.
Erases that occur near, but not at, the beginning of the plot file
are NOT considered initial erases, even if the commands preceding the erase
produce no actual output on the device.)
X.PP
X.TP
X.B b
X.B break,
same as erase in that it is a possible place to pause, but doesn't
erase the screen. The erase command basically has 2 functions: first,
it signals that the current frame of the plot is completed, and secondly
it erases the current frame of the plot so that the next frame can start
fresh. The break command only carries the first meaning. The ``next frame''
of the plot builds upon the previous ones. This is useful when you want to
be able to stop at various times as an image is being built up.
X.TP
X.B o x y
redefine
X.B origin
X(0,0) on the device (the lower left hand corner of the screen for
standard plot style
with no global translations via pen command line options)
as vplot (x,y). This shift applies to everything
until the next origin command. An origin command is not affected by previous
ones. Changing the plot style resets the origin to zero.
X.TP
X.B m x y
X.B move
the current position to (x,y).
X.TP
X.B d x y
X.B draw
a line from the current position to (x,y), and make this the
new current position.
X.TP
X.B w xmin ymin xmax ymax
set clipping
X.B window.
The initial window is set to the maximum dimensions of the
particular plot device. If the coordinate system is rotated,
the smallest clipping window with vertical and horizontal sides
that contains the desired rotated clipping window will be used.
If xmin > xmax or ymin > ymax, then an inverted window will
be used that should clip away everything.
X.TP
X.B T size orientation, string
Start
X.B text
mode.
A character
X.B string
is plotted starting at the old pen position (as
set by a previous move, draw, or text command).
A nullbyte terminates the string.
The character
X.B size
X(the height) is in units of 1/33'rds of an inch (Ug!).
The character width is font and character dependent.
The character
X.B orientation
is in degrees, and the angle is
measured counter-clockwise from the X-axis.
The carriage controls newline, carriage return, and backspace
are correctly interpreted.
The origin for newline and carriage return is taken as the
pen position as of the last move.
X.IP
A large number of special escape sequences for accessing multiple fonts, colors,
sizes, fatnesses, symbols, and positions of text are available. See man vplottext.
X.IP
The archaic text command
X.B t
has been left in the code only for backwards compatibility. It should no longer
be used, so I'm not going to even tell you the ridiculous format it used.
X.TP
X.B
G xpath ypath xup yup, string
An alternate text command, which uses
X.B GKS
notation.
The vector given by
X.B xpath
and
X.B ypath
is the ``text path vector'',
and the vector given by
X.B xup
and
X.B yup
is the ``text up vector'', as defined in the GKS standard.
Since it is important for these vectors to be very accurate,
both are measured in units TEXTVECSCALE (defined in params.h,
set to 10 at Stanford) times finer than normal vplot units.
X.TP
X.B f k
Set line
X.B fatness.
The integer
X.B k
specifies the number of additional lines
to be drawn parallel to, and one bit over from all
future lines. The extra lines are added symmetrically.
k=0 resets back to single-line mode. The fatness is scaled to approximate
the behavior of a 200 pixel per inch device.
X.TP
X.B c k
Select new
X.B color
from menu of 512 colors.
X.B K
is an integer from 0 to 511.
Colors 0 through 7 are guaranteed to be by default the Regis colors:
X0-background, 1-blue, 2-red, 3-magenta,
X4-green, 5-cyan, 6-yellow, and 7-white.
X(This is the order of colors in a color bar pattern on a TV.
It is used for that because on a black and white TV it makes a
grey scale.)
X.IP
Color zero is always the background color.
Monochrome devices should consider ANY non-zero color to NOT be
the background color.
X.IP
See important comments in the `set color table' command with regards to color
mapping.
X.TP
X.B C color red green blue
set
X.B Color
table:
Color number
X.B color
is set to have red value
X.B red,
green value
X.B green,
and blue value
X.B blue.
These are integers from 0 to 255, (or floats from 0. to 1. when using plas
and pldb in inch or centimeter units)
with 255 being fully on and 0 being fully off.
The corresponding `grey level' for grey-scale devices is given by
floor((4 * green + 2 * red + blue + 6) / 7). Note that the only way
to get grey level 0 is if all three color levels are 0.
X.IP
Vplot will try to give you the color you want, but this may not always be
possible. If the device has N settable colors, then colors
X0 through N-1 will be set exactly as you request.
If you attempt to define a color X outside
of this range, Vplot will pick which color in the range 0 through N-1
is the closest and map all requests for color number X to that available color
value.
Whenever any color in the range 0 through N-1 is changed, all the mappings
will be re-calculated (although of course what is already drawn or
stored cannot be changed.)
X.IP
This scheme is especially useful when for example mixing grey scales for
raster information and bright colors for labels.
The few bright colors which you might need are allocated to the first few
color numbers. Then the remainder of the lower half of the color scale is
filled with the grey level values you will need, but ordered so that the most
important grey levels come first.
In the upper half of the color table you define a normally ordered grey scale.
Now when you want to draw grey scales, you refer only to the upper half of the
grey scale and
vplot will automatically map your requests down onto the real available colors of
the particular device.
X.IP
Color zero is always the background color.
Color 0 is only mapped to if the match is exact.
X.TP
X.B a npts
X.TP
X.B afat xmask ymask
X.TP
X.B x1 y1, x2 y2, ...
Define polygonal
X.B area
for stippling (on monochrome devices) or solid
area fill with current drawing color (for devices with color).
The polygon is specified
by its vertices
X.B (x1,y1),...,(xn,yn).
X.B Npts
is the number of vertices;
the polygon is automatically closed only if necessary.
X.B Afat
is the fatness of the outline; 0 is the minimum, and -1 draws no outline.
The shading for monochrome devices is determined by the integer mask.
A point within the polygonal area is darkened if
X((x mod
X.B xmask
X== 0) and (y mod
X.B ymask
X)) is true, where
x and y are all points within the polygon.
For example, xmask=1 and ymask=1 fills the area completely,
and xmask=1 ymask=5 makes
horizontal bars spaced 4 vertical bits apart.
The origin for x and y coordinates used in shading
is device dependent but will usually be the lower left hand corner
of the device screen.
X.IP
As a special case, if either
X.B xmask
or
X.B ymask
is zero no shading is done. (The area filling routine for the device is never
even called.)
This is true for both color and monochrome devices.
X.TP
X.B A npts
X.TP
X.B x1 y1, x2 y2, ...
Fill polygonal
X.B area
with pattern or color.
Fills polygon with patterns loaded with the `l' command (q.v.).
The pattern number used is the same as the current drawing color.
Note that a pattern can either be a hatch-line pattern or an arbitrary
raster pattern, depending on the format of the `l' command used.
X.IP
The purpose of this scheme is to associate each color with a particular
fill pattern. Once a current drawing color is set,
all vectors will have that color and all
filled areas will have the associated fill pattern.
X.IP
Devices that can't fill with arbitrary patterns should simply fill solidly
with the current drawing color.
If no pattern has been loaded, the `A' command will fill solidly
with the current drawing color automatically.
X.TP
X.B l ppi nx ny ipat
X.TP
X.B XXXX..., ... (nx*ny X's)
X.B Load
raster pattern for `A' command.
Each
X.B `X'
is an integer containing a color number.
X(These color numbers can be mapped, etc,
just like color numbers in the `c' command.)
The
X.B X's
represent pixels in a rectangular
pattern of dimensions nx by ny.
X(In pldb format the
X.B X's
are single-digit Hex numbers.)
The pattern is repeated to fill the polygon.
The pattern is scanned so that the first ny numbers are the first line, the
second ny numbers are the second line, etc, for nx lines. The scanning of the
pattern is done TV-style, ie starting at the upper left and working left-to-right
and then top-to-bottom. (If in doubt, remember that patterns should appear
on the device in the same orientation as in pldb-format vplot files.)
X.IP
The pattern is given the pattern number
X.B ipat.
This pattern will be used for
filling by the `A' command when the current color is number
X.B ipat.
X.B Ppi
is used to scale the pattern; it says how many pixels per inch you
wanted this pattern to have.
E.g. on a 300 pixel per inch device
X.br
X.B l 300 2 2 17
X.br
X.B 0 1
X.br
X.B 2 0
X.br
represents
X.br
X01
X.br
X20
X.br
whereas
X.br
X.B l 150 2 2 17
X.br
X.B 0 1
X.br
X.B 2 0
X.br
represents
X.br
X0011
X.br
X0011
X.br
X2200
X.br
X2200
X.br
where the digits are color numbers for the corresponding pixels.
The result when you load a new pattern with the same pattern number
as one already defined is device-dependent.
X.TP
X.B l angle -1 numhatch ipat
X.TP
X.B fat color offset interval,
X.TP
X.B ...,
X.TP
X.B (numhatch * 2 sets of 4)
X.B Load
hatch pattern for `A' command.
The
X.B angle
gives the amount to rotate off horizontal. The
X.B `-1'
is a flag
to distinguish this case from the previous command.
X.B Numhatch
is the number
of sets of hatched lines to place in each direction (X and Y).
Each set of hatched lines has four parameters:
X.B fat, color, offset,
and
X.B interval.
The
X.B fat
and
X.B color
give the fatness and color of every line in the set. The
X.B interval
is the spacing (in regular vplot units) between the lines.
The
X.B offset
parameter displaces all the lines in the set.
It should be less than the repeat interval.
The purpose of
X.B offset
is so that you can
have two different sets of lines (differently colored, perhaps) interleaved.
All the X sets are specified, and then all the Y sets.
X.IP
X.B Ipat
is the pattern
number. (See above for explanation.)
X.TP
X.B v flag
Change
X.B overlay
mode.
X.br
Overlay mode controls the opacity of the background color of polygon and raster
fills (see `a',`A',`l',`r',`R').
If flag=0, the polygon area is cleared before the new pattern is filled in.
If flag=1, the new pattern is simply added to whatever is already there with
what is underneath showing through where the new pattern is color 0.
The default overlay flag can also be set in the command line.
flag=0 mode takes significantly longer to fill the polygon on many devices.
Some devices that have hardware raster or area fill may ignore this
option if they are unable to implement it.
X.TP
X.B n
X.B no-op
for word aligning. Does nothing.
X.TP
X.B p
X.B purge
or flush plot buffers.
X.TP
X.B z, string
Print
X.B string
out on the text screen of the plot device.
X.TP
X.B L npts
X.TP
X.B x1 y1, x2 y2, ...
Draw a
X.B polyLine

X.TP
X.B M npts mtype msize
X.TP
X.B x1 y1, x2 y2, ...
Draw
X.B Markers
of type
X.B mtype
and size
X.B msize
at the given set of points.
For small integer values of
X.B msize,
this is as defined in GKS.
For larger values, it is taken to be a font glyph number (for most fonts this
will correspond to the ASCII character number. However
X.B mtype
may still be valid
even when greater than 255 for some fonts.)
X.B msize
is measured in the same
units as text is.
X.TP
X.B s ndash
X.TP
X.B dash1 gap1, dash2 gap2, ...
Set line
X.B style.
This command is used to make dashed or dotted lines. It affects all
vectors produced by the `m', `d', and `L' commands.
X.B Ndash
is the number of dash-gap pairs in the pattern.
If
X.B ndash
is 0, then continuous vectors will be drawn.
X.TP
X.B J hjust vjust
Set text
X.B Justification.
Values have meanings set in the include file
X`/usr/include/vplot.h'. The finer points of text justification are
discussed in `man vplottext'.
X.TP
X.B F font precision overlay_mode
Set text
X.B Font
and
X.B precision.
X.B Font
is an integer from 0 on up. Font
numbers less than 100 are reserved for device-independent `gentext' fonts.
X.B Precision
is an integer zero through two, meaning: string, 0; char, 1; stroke, 2.
The generic vplot text routine gentext draws everything with stroke precision,
but only parses for ligatures at precision 2.
The standard `pen' font should be font number 0.
How many others are available is site-dependent, and should be documented
in `man vplottext'.
X.IP
The overlay mode is an integer from 0 through 3, with the following meanings:
X0: nothing unusual. 1: Draw a box around the text. 2: Clear behind the text
with a polygon drawn in the background color before drawing the text.
X3: both 1 and 2.
X.IP
All fonts, precisions, and text overlay modes are``#define''d in
vplot.h.
X.TP
X.B S styleflag
Set Vplot
X.B Style.
X.br
Style is a single character, with possible values
X`r' rotated, `s' standard, `a' absolute. Case distinctions
don't matter. These affect the scaling and orientation of the plot.
X``Standard'' and ``rotated'' styles are defined in the ``Coordinates''
section at the beginning of this document. Absolute style is like standard style,
except the plot is scaled to be in true inches. Some other archaic styles
are recognized (old, mazama) but should no longer be used.
The style is reset to the default at the start of every plot frame.
It is probably a good idea to set the style immediately after every
X.B erase
command, especially if the style you want to use is not STANDARD.
X.TP
X.B R orient offset

Byte deep
X.B Raster
data, each point having
X.B offset
added to it as it is
read in. It is
X.B xpix
pixels wide and
X.B ypix
pixels tall, with lower left hand
pixel at
X.B (xll, yll)
and width
X.B xur-xll
and height
X.B yur-yll.
X.B Linerep
tells how many times to repeat the following raster line.
X.B Numpat
gives the number of repetitions
of the following
X.B numbyte
bytes
X.B b1, b2, ... bN
within a line.
This is repeated until all the bytes within the raster line have been
accounted for. (The last byte of the line must also be the last byte of
the repeat pattern.) The same holds for the loop over lines.
X.IP
The orientation of the axes of the raster is determined by the value of
X.B orient.
For
X.B orient=0
the raster is oriented TV-style, with the fast axis
left-to-right and the slow axis top-to-bottom. For each increase of 1 in the
value of
X.B orient,
the raster rotates 90 degrees clockwise.
X.IP
Note that the lower-leftmost pixel of the raster image will be exactly at
the vplot coordinate
X.B (xll,yll).
However, the point at vplot coordinate
X.B (xur,yur)
will be the pixel just outside the raster image, touching the upper-rightmost
corner. Things were done this way so that
X.B xur-xll
for example gives the width
of the raster data box in vplot units.
X.IP
The
X.B offset
parameter is provided so that there is some way to access color
table values greater than 255. (For example, 4 different 64-value color
schemes could be defined in the color table in slots 256-511. You could switch
between these by merely changing the value of
X.B `offset'.

Same format as the `R' command, except that the data is encoded in bits
and
X.B rastermult
is multiplied by the value of each bit.
X8 bits are encoded into each byte, in each
byte the bits ordered from highest to lowest. As many bytes are used as are
needed to hold
X.B numbit
bits. For example, 13 bits would be encoded as
X.br
X.B
b1: (1 2 3 4 5 6 7 8) b2: (9 10 11 12 13 X X X).
X.TP

X.SH "BUGS"
There may be no bugs in the vplot language, but there are
in the programs which read and write it.
X.PP
I had a heck of a time with troff bugs eating words and characters
while trying to write this, so if
something seems to be missing you might refer back to the unformatted
original.
X.PP
Vplot at Stanford suffers somewhat by the restriction of having to remain
backwards compatible to the stone age (1980). The vplot coordinate system is
integers, with 600 pixels to the inch. A much higher resolution should be
used! This isn't too hard to change, all you have to do is to make plas and pldb
write and read 4 bytes instead of 2. (Plas and pldb already work with integers
anyway, and there are no short ints used in the code anywhere.)
Several other `magic numbers' show
up in this documentation as well. These are defined in `vplot.h' and `params.h'.
I recommend that any new site starting to use vplot from scratch change these
numbers to more reasonable values. If ALL code uses the #define's in vplot.h,
as all Vplot source code (hopefully) does and all user code ought, then these
values can be changed without breaking any programs, only old metafiles.
X.SH "AUTHOR"
Robert W. Clayton began the vplot software while in the
Geophysics Department at Stanford University (circa 1979) on a PDP-11.
He was last seen at Cal Tech.
Since then
Jeff Thorson,
Stew Levin,
Jon Claerbout,
Dave Hale,
Ron Ullmann,
Glenn Kroeger,
Michel Debiche,
Shuki Ronen,
Doug Wilson,
Wes Monroe,
Chuck Karish,
Steve Cole,
Clement Kostov,
Kai Lanz,
Jean-Luc Guiziou,
and especially
Joe Dellinger have altered and expanded it almost beyond recognition,
for the most part preserving backwards compatibility, even when that required
compromising of ideals.
This manual page was hacked together by Joe Dellinger out of an ancient and
out-of-date original by Michel Debiche, which was itself a hack of something
even more ancient of unknown origin.
