DR SET LINE SPECS

version 6.0

DR SET LINE SPECS (area; scope; startH; startV; endH; endV)

Parameter	Type		Description
area	Longint		4D Draw area
scope	Longint		-1 = All, 0 = Selected, >0 = Object ID
startH	Real		Horizontal position of start
startV	Real		Vertical position of start
endH	Real		Horizontal position of end

The command DR SET LINE SPECS resets the endpoints of the line in area described by scope.

• If scope equals -1, the command affects the endpoints for the first object in the document.

• If scope equals 0, the command affects the endpoints for the first selected object.

• If scope is greater than 0, it must be equal to a specific line's ID; the command affects that line's endpoints. If the object does not exist, DR SET LINE SPECS does nothing, and DR Error returns error number 2.

If the object described by scope is not a line, DR SET LINE SPECS does nothing, and DR Error returns error number 47.

The line is repositioned according to startH, startV, endH, and endV. All four coordinates are expressed in base units. Use the DR Scale to base function to convert from scale units to base units. startH, startV, endH, and endV are specified as offsets from the current origin.

Positive values indicate a position below or to the right of the origin. Negative values indicate a position above or to the left of the origin.

See the example for the DR GET LINE SPECS command.
