Well, I can manage the drawing part, but can anyone tell me how you can send a drawing via email? I know how to send textual matter, but this is really confusing!
Just kidding… There are a few things they could be doing.
-Recording the drawing as an array of points (x,y)
-Saving the drawing to a server somewhere
-Reloading the array as an XML document from an embedded swf in the email
or maybe there is a feature of server side flash…(no experience here) that lets you convert it to a jpg and email that.
I did a semi-similar thing (currently offline)… basically, i store the coordinated of the points in an array, convert the array to a string, and then store it in a mysql database. When i retrieve them, I plug em into a function that ‘visualizes’ the points…
What they do is probably the same, and the link you get in the email tells flash to load that particular entry in the database…
