Easel web graphics.

Image
Easel is sort of a new "Logo" turtle language for web pages. You can create graphics very easily. They have a server for the time being, so you do not have to host the software. That is a plus. The package comes with many demonstration html pages to work with. Below is a super basic example. Simple beginner web page. <!DOCTYPE html> <html> <head> <script src="http://code.createjs.com/easeljs-0.7.0.min.js"></script> <script> function init() { var stage = new createjs.Stage("demoCanvas"); var circle = new createjs.Shape(); circle.graphics.beginFill("red").drawCircle(0, 0, 50); circle.x = 100; circle.y = 100; stage.addChild(circle); stage.addChild(new createjs.Shape()).setTransform(100,100).graphics.f("red").dc(0,0,50); stage.addChild(new createjs.Shape()).setTransform(100,100).graphics.f("green").dc(200,0,50); stage.update(); } </script> </head> <b...

One nice thing is that if you find a page with a tool that you need, under certain circumstances, you can save the page for later use. In some cases, if it is going into an educational environment, the advertisements have to go away. That is what was done with this web page. Before: After editing the source code: So there are more uses for knowing html, javascript, and css than for just creating your own web page.  One of many sites to get free code: http://www.free-javascripts.com.
