35.8. Summary

• Drawing vector graphics programmatically in Flash Player is performed through the Graphics object.

• You can't instantiate a Graphics object or put it in the display list. Use the graphics property of a Shape, Sprite, or MovieClip instead.

• Graphics objects are state machines.

• Basic path operations include moving the "pen," drawing a straight-line segment, and drawing a curve.

• To stroke a path, you must first set a line style with lineStyle().

• Line styles can be followed by stroke fill styles for non-solid-color fills.

• To fill a path, use begin[kindof]Fill() methods and endFill().

• Clear the canvas by calling clear().

• Strokes and fills may be styled with solid colors, gradients, bitmap fills, and shader fills (varies by Flash Player version).

• Draw primitives with methods like drawRect() and drawCircle().

• Paths can be stored as lists of command types and coordinates and drawn with drawPath() (varies by Flash Player version).

• Paths, fills, and strokes can be encapsulated in drawing command objects that implement IGraphicsData and drawn with drawGraphicsData() (varies by Flash Player version).

• Mapping textures to polygons is possible with drawTriangles() (varies by Flash Player version).
