HPGLPENS.PS
(set HP-GL pen colors)
The
HPGLPENS.PS
Þle changes the color and width of the default pen
colors. The HP 7475A plotter has only six pens, but the printer's emulation
supports up to 256 pens. In
HPGLPENS.PS
, pen number, pen width, red
value, green value, and blue value are listed in parentheses after
ColorSetup
.
/ColorSetup (
pen_number width red_value green_value
blue_value...
)
The pen color change is persistent across jobs but not across printer power
cycles; it affects all HP-GL jobs that immediately follow it until the next
printer reset. In the example below, all pen widths are set to 0.35
millimeters. Pen 0 is white (this is the background pen color), pen 1 is black,
pen 2 is red, pen 3 is green, pen 4 is blue, pen 5 is cyan, pen 6 is magenta, and
pen 7 is yellow.
