    Most of my apps are based on user drawing something, for example, I have one where I use graphics in a forensic environment and load a scene image and then place “markers” (really dots) on the screen to indicate points of interest. I’ve indexed these items and linked them to a SQL database where I can elaborate on what the marker represents. Additionally, I have “markers” on medical anatomical outlines to indicate wounds, trama, etc. and want to index these to a database and link (and display in a popup) actual detailed images of what the wound looks like with textual narration.

    So, primitive graphics: line, arc, circle, rectangle, ellipse, etc. are needed. I’ve tried using javascript, but am not well-versed in js programming. Also, getting mouse (or touch) XY position is useful, though I figured that out, but a library of simple mouseover, drag image, etc. library with simple instructions would be nice.

    You guys are really busy and I appreciate all you do. Just thought I’d put my 2 cents worth in. I bought MobiOne and am very, very impressed and pleased with what it does so far.

    I can send a short video on my forensic app and show you where I’m headed if you want. If so, let me know where to send the link…
    Thanks,

    Hi wildwex

    I’m also not a Javascript expert but have had some good success with createjs in a brower. Its a really easy library to learn and lets you pretty easily create and animate the shapes you will need for your apps. I just have not quite got it working in Mobione at the moment. I can’t quite figure out how to get a shape drawn into the canvas in mobione yet!

    I don’t think its that difficult as in your other thread a similar library has been used. I would very much like to use the similar features you want, and think an external JS library is the way ahead.

    Any chance of a little how to?

    Paul
