LT - Line type selection
LT [, n [, p [,m ]]] [;]
n ; Line pattern number
p ; Line pattern length (percentage or millimeters of distance between P1 and P2)
m : mode
• This command specifies the line pattern for use when drawing lines with the vector group commands.
• n defines the line type to be used.
• Values of n from 1 to 8 specify a line type (as defined with the UL command) and use a fixed pattern length.
Any residual part of the pattern not used on a particular drawing operation is stored and used at the start of
the next line drawn.
• Values of n from -1 to -8 specify a line type (as defined with the UL command) and use an adaptive pattern
length - that is, the pattern is scaled so as to fit one or more complete patterns into the line.
• If n is 0,
a dot is placed at the (X, Y) coordinates specified with any vector commands used.
• p, the pattern length, specifies the length of one complete pattern,
between P1 and P2 or in millimeters.
length is omitted, the printer uses the most recently specified pattern length.
• If a zero or negative pattern length is specified the command is ignored.
• m, the mode, defines whether the pattern length parameter, p, is interpreted as a reading in millimeters,
(m=1), or as a percentage of the distance between P1 and P2, (m=0).
command, the most recently specified mode is used.
• LT99; restores the previous line type (and, if it is a fixed line type,
line type is solid and that the pen position is the same as it was when the current,
selected.
• An LT command remains in effect until another LT command is issued,
restored with the DF command
• If no parameters are specified the line type is set to be solid.
any line residue are saved.
