The flash file is draw.fla - it's the source for the drawing editor. At the bottom of the file are the MovieClip prototype extensions for drawing all the different shapes. This code should port straight over to js no problem (it is js essentially); there is a function DRAW.prototype.getData which shows exactly how all the various nodes are constructed and there's a function setData() which shows how the XML is parsed to create the drawing. I think you can figure it out from those functions, setData() might do a lot of what you need with some modification,

I'll send the details. I have javascript(ish) code for drawing all the various shapes, so I think you'll be OK, I'll dig those out too. If you can open the engine file, you can see for yourself: the DRAWING class, and some movieclip prototype extensions that handle the various shapes. I didn't creates classes for each shape though, so DRAWING is quite a big (read 'slightly messy') class. The drawing fla file shows how each xml node can be created (can't remember the exact name of the file, but you'll see it with the others in the svn) ________________________________________

Hi

Just need to get my head around:

how the overall size of the box that is rendered is determined (is it calculated simply from the highest used x and y cords??) - the data needs to be parsed prior to using the canvas tag as any resize forces a wipe so need to know dimensions in advance of starting drawing,

what to expect from every possible <shape> data set since each different object type has a different subset of parameters (a few samples of each data type to run through my model should be sufficient for testing),

whether its even worth maintaining an html4 equivalent for some of the shape types (in cases of no <canvas> tag support) As i said the screenshot that i sent  of the freehand path down the mountain is actually rendered using <div>s as I've not got my head around section 1 yet... It can support images, boxes, text and lines to some extent but drawing circles,stars,gears etc would make the dom extremely slow i suspect, bloated with pixel wide divs

Happy to carry on with this one for a bit though :-)

Anyone have any thoughts on the above?

Re: the textDrawing one, do you mean you need to know the full extent of the xml that describes the drawing? I think it will convert to <canvas> but haven't checked, I can figure out the xml for you from the code in the engine,

Hi,

I know I'm new here but personally I think that JSON export would at least be as useful if not more useful as XML, especially when working in a JavaScript environment like the HTML5 engine. (see next part)

Incidentally, not sure if I only have commit access to XOT since XERTE desktop is being treated as almost dead in the water but the Xenith code i'm working on is part of the XERTE trunk, not XOT. My interest is just now is getting the HTML5 engine mature enough to use in anger. Over the weekend i've done the following HTML5 engine models:

     delicious (95% ready) - had to use JSONP request because of same origin policy
     youtuberss (95% ready) - have use new JSONC request
     textDrawing (<50%) - don't have a sufficient test file for this model and the XOT Jisc site won't save the image or let me add pictures just now... need to get XOT installed locally or use usb version temporarily (anyone help out with a test XML stub for this model??) Oh and the screenshot shows the freehand done using pixel <divs> for non canvas compatibility
     youtube (~80% ready) - just a guess as only a few sizing issues

Attached some screenshots for those who want to see.

I'ml definitely interested in working on the connector pages soon though and tying this altogether as we want a "mobile" compatible (read iPad) RLO repository of some fashion by the end of the academic year.

Also, would JSON export be more useful / as useful as XML export?
