Draw Line

Purpose

The Draw Line function draws a simple line segment between two points.

Syntax

Opcode format	Opcode [ASCII] (Hex)	Operand Format	Comments
Single-byte, readable operand	[L] (4C)	[<ws>]<I_X1>,<I_Y1><ws><I_X2>,<I_Y2>	Absolute coordinates.
Single-byte, binary operand	[l] (6C)	<L_X1><L_Y1><L_X2><L_Y2>	Relative coordinates
	[Ctrl-L] (0c	<S_X1><S_Y1><S_X2><S_Y2>	Relative coordinates
	(8c)	<B_Count>[<S_X1><S_Y1><S_X2><S_Y2>]⁺	Multiline, relative coordinates

X1, Y1 Logical point the line segment is drawn from

X2, Y2 Logical point the line segment is drawn to

Count Number of line segments that follow; count must be at least 1 and less than 256.

Details

The Draw Line Function is the basic opcode for drawing a line segment. The line is rendered using the current "Line Weight", "Line Cap", "Line Pattern", and "Visibility" attributes.

Notes

This function is generally only used when the line segments are not connected to each other. To draw a series of connected line segments, the Polyline function should be used.
