In AutoCAD to draw a building plan often need to draw some objects of the floor plan, such as tables, chairs, bonsai, and so on, most objects are dedicated library can be called directly. Lotus in general building plans rarely encountered, so most of the library does not have this block, then we have to draw a hand, in fact, drawing Lotus is very simple, 5 commands can be achieved, the final effect chart is

This article introduces JavaScript code for implementing simple Canvas drawing instances. If you need it, refer to it. Define variables:[Javascript] The Code is as follows: Var startX;Var startY;Var endX;Var endY;Var radius;Var canvas = document. getElementById ("myCanvas ");Var context = canvas. getContext ("2d ");Var select = document. getElementsByTagName ("select ");Var startX;Var startY;Var endX;Var
