HP PCL Graphics Commands 9-25
Table 9-1 Line Type Command Parameters
Parameter Format Functional Range Default
line type (fixed or adaptive) clamped integer -8 to 8 solid line
99 restores previous line
type
pattern length clamped real > 0 4% of the distance
between scaling points
P1 and P2
mode (relative or absolute) clamped integer 0 or 1 0 (relative)
The LT command applies to lines drawn by the AA, AR, AT, CI, EA, ER, EW, FP, PA,
PD, PE, PR, RA, RR, RT, and WG commands. Line types are drawn using the current line
attributes set by the line attribute (LA) command. For example, if you have used LA to
specify rounded ends, the printer draws each dash in a dashed line pattern with rounded
ends.
If no parameters are entered, the LT command defaults the line type to solid and saves the
previous line type, pattern length, and any unused portion of the pattern (residue). LT99
restores the previous line type (and residue if it is a fixed-line type).
Line Attributes (LA)
LA kind, value [, kind,value [, kind,value; ]] or LA [ ; ]
This command specifies how line ends and line joins are physically shaped. Use this
command when drawing lines thicker than 0.35 mm.
Table 9-2 Line Attributes Command Parameters
Parameter Format Functional Range Default
kind clamped integer 1 through 3 1
value clamped integer Kind 1: 1 - 4 1 (butt)
clamped integer Kind 2: 1 - 6 1 (mitered)
mode clamped real Kind 3: 1 to 32,767 5
There are three line attributes: line ends , line joins , and the miter limit . The LA command
parameters are used in pairs: the first parameter, kind , selects a line attribute; the second,
value , defines the appearance of that attribute. The printer uses the current line attribute
when the optional parameter pairs are omitted.
No parameters - Defaults the line attributes to butt ends, mitered joins, and a miter limit of
5. Equivalent to (LA1,1,2,1,3,5).
