InputDraw

<InputDraw/> is a cross-browser, fast, simple to integrate widget to use in your forms as a drawing tool and everywhere else as a viewer.
It uses SVG as a describing language of drawing. Being a standard, SVG can afterwards be used by a large number of applications, widgets and libraries.
In order to use this widget, you don't need to be a programmer or even know any web programming language like PHP, Ruby, Python, .net, Java, Smalltalk, etc.. Actually, you only need to know some html, what a form is and our JavaScript command to make it work.
<InputDraw/> uses flash technology so almost everyone can use it. Remember that there are more installations of flash than windows.
You can use the non-commercial license for free, just download it on the <InputDraw/> site.
For commercial sites, you can also buy the license and receive the commercial package.
