Paths: Drawings on Macro-Vision






Paths: Drawings on Macro-Vision

The GraphicsPath class lets you collect several of the more primitive drawing objects (like lines and arcs, and even rectangles) into a single grouped unit. This full path can then be replayed onto a graphics surface such as a macro.

Dim thePath As New Drawing2D.GraphicsPath

thePath.AddEllipse(0, 0, 50, 50)
thePath.AddArc(10, 30, 30, 10, 10, 160)
thePath.AddRectangle(New Rectangle(15, 15, 5, 5))
thePath.AddRectangle(New Rectangle(30, 15, 5, 5))

e.Graphics.DrawPath(Pens.Black, thePath)

thePath.Dispose()

This code block draws a smiley face on the canvas (see Figure).

That's cute. Fortunately, there are other uses for graphics paths, some of which I'll discuss in the following section.
