I have been developing with Java for many years and I have been building a GWT based application in the last six months. But I do not have almost any Flash or Action Script experience and I want to try some hobbies with Flex programming. Particularly 2D graphics and image manipulation will be interesting topics.
Adobe's tutorials for Java developers are naturally the starting point but I need some points for graphics, drag the 2D graphics or modify the user-uploaded image based on the data from the server. How much can be done on Flex and what should be done on the server side?
You do not need a 'full' flex library for drawing; Flex mainly gives you GUI components And provide some ways to easily integrate your back-end server.
Check graphics objects if you just want to do something - it works like a Java graphics object.
If you want to modify the image uploaded by the user who is already on the server (because the image was uploaded) - although new flash player (10 versions) add some of the local data , So it is also possible to show a modified image that was not uploaded, for example see.
Flex / AS3 will feel a bit awkward for a Java programmer - its parts are very easy and other parts will be disappointing, tooling support is poor, slow compiler, jump through many hoops There is no support for running alone (I did not start ...) but as a deployment forum, I have to say that I like it.
