Read tutorialThe term double buffering refers to a technique for buffering a graphics context before displaying it. The idiom requires that you use two graphics contexts -or buffers - hence its
Read tutorialThe point (x, y) specifies to a drawing function a location relative to the point (0, 0). The point (0, 0) is the origin of the Graphics. When you first obtain a reference to your
Read tutorialTo draw text, specify the anchor point and the weighting of the anchor point. You can also specify the font of the text to be drawn.
Read tutorialThe Graphics class also supports the drawing of arcs. To draw an arc, you must specify six parameters. These parameters are the four quantities that define the arc's bounding recta
Read tutorialYou can draw two kinds of rectangles: regular and rounded. Rectangles, like all geometric drawing, can be drawn in different colors by specifying the color of the graphics pen.
Read tutorialTo draw a line, you must specify the (x, y) coordinates of its start and end points. The (x, y) coordinates are defined relative to the point (0, 0), which, at the time the graphic
