Hi,
I'm building an app in eyeOS to share a presentation created with
openoffice. i'm using qooxdoo 1.3
The most important use case is sharing doodles on a slide. The user draws
something on a slide and other attendees will see it. A slide is a
qx.basic.Image component.
I was wondering if I could get some ideas from you to make this work with
qooxdoo. I've found some old e-mails of people developing apps that use SVG
somehow [1], but sometimes I can't figure out if they'll be useful for me
and I have to read lots of documentation.
I think there are two subproblems: sending data in real time (so other
users see how you draw your doodle) and the format of the data the user
sends.
For example, I thought about using the canvas [2] element, but looks like
it only supports one primite shape: rectangles.
I could use SVG, to store the doodle. I don't really know how to capture the
input. I'd like the user to draw freely on the screen. If I work this out,
we may eventually build a GNU Paint like program made with qooxdoo, which is
quite exciting.
I've also seen Graffiti Markup Language, which also stores time information,
but SVG looks widely used.
simple put: I want to draw on top of a picture but I don't need to modify
it.
