Line attribute commands
The HP-GL/2 filter does not support the following attributes for the line
attribute setting commands and will ignore them if they are included:
HP-GL/2 filter coordinates
Like other HP plotters, the HP-GL/2 plots using single 0.025 mm units. When
plotting on paper however, the printer's or plotter's resolution determines the
plot units.
The following explanation covers the HP-GL/2 filter's start coordinates, plotting
origin, and scaling point.
The HP-GL/2 filter uses the initial coordinates, plotting origin, and scaling
point to begin processing input data. Input data that has minus coordinates
and originates from other than the bottom left area (P1) or the hard clip limit
(the PS command-specified area) is shifted by the minimum value of each last
drawn coordinate to the plotting origin (where X and Y intersect, in the minus
direction).
Likewise, the coordinates of images that are drawn in the plus direction are shift-
ed similarly. Images that exceed the hard clip limit are not output.
If the HP-GL/2 filter's clipping option is enabled (overriding the hard clip limit
of the PS command), the data is output with the hard clip limit reset to the im-
age's minimum and maximum value for each co-ordinate, and independent of
the original position and the hard clip limit.
