2、关于FXG

FXG (Flash XML Graphics) was created by Adobe as a language that represents graphical objects in a Flex application. Its capabilities closely follow the rendering model of Adobe Flash Player 10. There are many similarities between FXG and SVG (Scalable Vector Graphics), another XML language that represents graphics that’s been available for many years. In fact, the Adobe development team first considered using SVG, but decided to create a new language because the existing SVG didn’t match how graphics are rendered in FlashPlayer. Many Adobe Creative Suite products are able to export graphics as FXG markup, including Photoshop,Illustrator, and Fireworks.
