创建接受草图输入的用户界面
我想创建一个简单的应用程序，要求用户绘制他们已显示的图像。一旦用户完成图像，程序就会对绘图进行评分。是否有任何现有的库用于创建接受用户草图/绘图的界面？我需要一个可以处理的草图对象（可能是矢量图）。
该程序应在平板电脑和触摸屏笔记本电脑上运行，最好在 Windows 上运行，但多平台将是理想的选择。我愿意使用最适合这个项目的编程语言。
目前我正在查看 SATIN 库（http://dub.washington.edu:2007/projects/satin/），但它相当旧，最后一次更改是在 2001 年。
I would like to create a simple application asks the user to draw an image they have been shown. Once the user has completed the image the program would score the drawing. Are there any existing libraries for creating interfaces that accept sketches/drawing from users? I need a sketch object (maybe as a vector graph) which can be processed.
The program should run on tablets and touch screen laptops, preferably on windows however multi-platform would be ideal. I am open to using what ever programming language is best for this project.
Currently I am looking at the SATIN library (http://dub.washington.edu:2007/projects/satin/) but it is rather old, the last change was in 2001.

也许你可以试试铅笔。它是 Firefox 的附加组件，您可以轻松绘制一些草图模式（或模型）。
下载 Firefox 版 Pencil
Maybe you can try Pencil. It's a add-ons for firefox and you can easily draw some sketch schema (or mockup).
Download Pencil for Firefox
