DESCRIPTION
Files of this format are interpreted for various devices by commands.
A graphics file is a stream of plotting instructions. Each instruction
consists of an ASCII letter usually followed by bytes of binary infor‐
mation. The instructions are executed in order. A point is designated
by four bytes representing the x and y values; each value is a signed
integer. The last designated point in an l, m, n, or p instruction
becomes the ``current point'' for the next instruction.
m Move: the next four bytes give a new current point.
n Cont: draw a line from the current point to the point given by the
next four bytes.
p Point: plot the point given by the next four bytes.
l Line: draw a line from the point given by the next four bytes to
the point given by the following four bytes.
t Label: place the following ASCII string so that its first charac‐
ter falls on the current point. The string is terminated by a NEW‐
LINE.
a Arc: the first four bytes give the center, the next four give the
starting point, and the last four give the end point of a circular
arc. The least significant coordinate of the end point is used
only to determine the quadrant. The arc is drawn counter-clock‐
wise.
c Circle: the first four bytes give the center of the circle, the
next two the radius.
e Erase: start another frame of output.
f Linemod: take the following string, up to a NEWLINE, as the style
for drawing further lines. The styles are ``dotted,'' ``solid,''
``longdashed,'' ``shortdashed,'' and ``dotdashed.'' Effective only
in plot 4014 and plot ver.
s Space: the next four bytes give the lower left corner of the plot‐
ting area; the following four give the upper right corner. The
plot will be magnified or reduced to fit the device as closely as
possible.
Space settings that exactly fill the plotting area with unity
scaling appear below. The upper limit is just outside the plotting
area.
In every case the plotting area is taken to be square; points outside
may be displayable on devices whose face is not square.
