Flash progressive fill debugging and personal feeling

Code Debug Program

P.S.
The recent development of a flash component requires the use of as code to implement gradients (Begingradientfill). The matrix that I used for this method has always been a smattering. I went to the internet to find some relevant information, said is not very clear! So I wrote the debugger myself and made a basic understanding of the method. Hope for everyone to a little help, this is also called "Use the program to learn the program"! At the same time I also hope those who learn as coding, can also learn this mode of thinking, some do not understand the method, can "use the program to learn the program" to let themselves understand the practical meaning of the method! It's a lot better than watching those boring words.
"In fact, learning flash development is not boring"!
