Re: How to use WPF to implement multi-pen drawing?
Here are two examples can be run, using VS2008 and. Net FrameWork3.0。 https://skydrive.live.com/redir.aspx...6DA8D15AEE!103
Delay example, the longer the draw, between the mouse and lines will be a very significant delay (after the mouse to stop, delay disappeared), and CPU utilization much, mainly because of the mouse each take a sampling point, we need to re-draw the lines；Non-delayed example you will find that handwriting is very smooth, although take up memory, but not as good as the first clear, the key is not that obvious delay.
My aim is to achieve multi-pen, refers to more than one person can use the stylus on the touch pad or finger free writing, which requires hardware support. Currently there is no hardware problem, the problem is a multi-pen when the delay is not significant (due to hardware limitations, there will be some delay in itself).
Examples of the use of delayed implementation, to achieve multi-pen, but the process caused the delay with the hardware itself, and do not make people suffer; example if the non-delay multiple ways to achieve freedom of writing, then, is an ideal, but I can not find how to DynamicRenderer the RootVisual simultaneously display different handwriting method.
What should I do here? how achieve multi-pen? Are there other ways? Please help me!
