Plotter Termcap Usage
Plotter size
|
Name |
Description |
|
px#num |
Device resolution on X axis |
|
py#num |
Device resolution on Y axis |
The "px" and "py" describe the number of addressable positions on the X and Y axes.
Color/Pen Capabilities
|
Name |
Description |
|
pn#num |
Number of colors/pens |
|
sp=str |
Parameterized string for color/pen selection |
|
xp=str |
Same as sp, but selects an XOR pen |
|
pw#num |
Pen width in plotter resolution units |
|
pu=str |
Lift pen from surface |
|
pd=str |
Lower pen to surface |
Starting/Stopping the Plotter
|
Name |
Description |
|
is=str |
String to initialize the plotter. Sent prior to any plotting commands. |
|
es=str |
String to finish plot. Sent at the close of the device. |
Line Drawing
|
Name |
Description |
|
mv=str |
Move to coordinates |
|
dr=str |
Draw to coordinates |
|
st=str |
Set a point at coordinates |
|
lx=str |
Select line style "x" (0..9) A sequence of entries defining line styles 0 (solid) through 9. The Character Devices section contains a description of the line style numbers and the plotted representation. |
The "mv" and "dr" strings use the same format as the termcap cm= sequence and add the following sequences:
|
%I |
Tek 4010 X positive |
|
%J |
Tek 4010 Y positive |
|
%Z |
Tek 4105 X and Y |
The "mv" and "dr" strings describe parameterized strings used for moving the pen around on the surface. If the "dr" string is defined, it will be assumed to also perform a pen up command.
As an example consider the following termcap entry for a HP7475 plotter:
#
# plotter entry for HP7475 type plotters. Does
# setup to plotter requiring xon/xoff line
# control.
