Does anyone know of a webcanvas . plugin. I have a customer who wants to have a customer sign a box on a web app with his signature to confirm a delivery. I know this is no really possible with the built in canvas in a web app. Does anyone know a Xojo plugin which can do this?
MBS WebStarterKit includes a Web Signature example:

I could not find one on Graffitisuite, but as always Christian comes though ! Thanks Christian. 
GraffitiSuite Web Edition does have a signature class.
