在WPF中绘制百万点线 [英] Draw million points line in WPF

问题描述

我想绘制包含近1000000个点的线，并且还希望在1秒内完成此渲染。

你能否建议我如何在wpf中绘制高性能系列。



我尝试了什么：



我尝试了PolyLine，StreamGeometry并尝试了DrawingVisual，但是这些类需要几秒钟才能用50k点画线。

I want to draw the line containing nearly 1000000 points and also wants to do this rendering within 1 second.
Could you please suggest how i can draw high performance line in wpf.

What I have tried:

I tried PolyLine, StreamGeometry and also tried DrawingVisual, but these classes takes several seconds to draw line with just 50k points.

不要这样做！

相反，绘制数据1次，拍照，保存在服务器上，然后将图片发送到客户。

另一种方法是减少加速渲染的点数。

Don't do it !
Instead, draw the data 1 time, take a picture, save it on server, and just send the picture to the client.
Another way is to reduce the number of points to speedup rendering.
