Method Draw is a fork of SVG Edit, a web based SVG editor. And we just got it working in FileMaker:
As you see we have script to initialize, load and save. So you can have a full featured drawing area in your FileMaker solution. Works fine here with FileMaker 11 on Mac, 13 on Mac and 13 on Windows. Other versions need to be tested.
Will be included as example with upcoming plugin release.
PS: We have also an example for Xojo to do similar.
