+This example shows how to use the Graphics to draw the head of a violin.
+
+The comparable uncompressed .jpg photo image of the violin head was 161KB, .png(24-bit) was 359KB. +The Graphics code to render this example is 18KB. +

+
+Path Drawing Tool
+ ++
+ Try this simple tool that helps you by generating code while you interactively + draw graphic paths. + +
+
+ + As you drag the pencil icon, corresponding graphics code is auto-generated. + This code can be copied and pasted into a graphics instance to reproduce + the paths you created with the pencil. +
++ The violin example was created with this tool. +
