TPostScriptPrinterCanvas.Polyline procedure

Declaration

procedure Polyline(Points: PPoint; NumPts: Integer); override

Description

Not described here; this is what TCanvas.Polyline says of it:

Draws a line which connects a set of points on the canvas.

Use Polyline to connect a set of points on the Canvas. If you specify only two points, Polyline draws a single line. The Points parameter is an array of points to be connected.

StartIndex identifies the first point in the array to use.

NumPts indicates the number of points to use. If NumPts is -1 (the default), PolyLine uses all the points from StartIndex to the end of the array.

Calling the MoveTo function with the value of the first point, and then repeatedly calling LineTo with all subsequent points will draw the same image on the canvas. However, unlike LineTo, Polyline does not change the values in PenPos.
