All the shapes in Figure 415 were edged using a DrawXxx function from the Graphics object for the form for example, DrawArc and DrawBezier The shapes that can be filled were drawn using a FillXxx function, such as FillClosedCurve and FillEllipse Not all of the shapes could be filled because not all of them are closed shapes; for example, there is no FillCurve However, all the open shapes (except the Bezier) have closed-shape equivalents; for example, a filled arc is called a pie Also, notice the use of the Lines shape This shape could be drawn using multiple calls to the DrawLine function, but three of the shapes line, rectangle, and Bezier have helpers that draw more of them at once In addition to being convenient, these helpers handle the appropriate mitering at intersections that you'd otherwise have to do by hand For example, the Graphics object provides all the following functions for drawing rectangles: DrawRectangle, DrawRectangles, FillRectangle, and FillRectangles

Most of the shapes are specified as you'd expect You specify the rectangle and the ellipse using an x, y, width, and height, or a Rectangle object You specify the arc and the pie as with a rectangle, but you also include a start and a length of sweep , both specified in degrees (the shown arc and pie start at 180 degrees and sweep for 180 degrees) The lines and polygon are specified with an array of points, as are the curves, but the curves are a little different The curve (also known as a cardinal spline ) acts just like a set of lines, except as a point is approached, there's a curve instead of a sharp point In addition to a set of points, the curve is specified using a tension , which is a value that determines how "curvy" the curve is around the points A tension of 0 indicates no curve, and a tension of 05 is the default The tension

Figure 416 shows the same set of points (as indicated by the black dots and index number) drawn using the DrawCurve function with three different values of tension As the tension increases, so does the amount of curve at each point Unlike normal curves, Bezier curves are specified with exactly four points: one start point, followed by two control points, followed by an end point If the DrawBeziers function is used to draw multiple curves, the end point of the preceding curve becomes the start point of the nextFigure 417 shows three Bezier curves drawn using the same set of points, but in different orders

In each case, the Bezier is drawn between the start point and the end point, but the two control points are used to determine the shape of the curve by exerting more "control" over the curve as they get farther away

"smoothing," as evidenced by the jagged edges The jagged edges are caused by the swift transition between the color of the shape being drawn and the color of the background A technique known as antialiasing uses a smoother transition between the shape color and the background color, in much the same way that a gradient brush provides a smooth transition from one color to another To turn on antialiasing for shapes subsequently drawn on the Graphics object, you set the SmoothingMode property: gSmoothingMode = SmoothingModeAntiAlias; The default value of the SmoothingMode property is SmoothingModeNone In addition to the AntiAlias value, SmoothingMode has three other values: Default, HighSpeed, and HighQuality These are merely aliases for None, None, and AntiAlias, depending on your system settings Figure 418 shows the difference between using and not using antialiasing
