I want to get the coordinates of the four corners of a rectangle which is drawn by the user using canvas.
When the user click on the “submit coordinates” button , the variables x,y,h(height) and w(width) values should be passed to the Servlet to do some calculationsn so to get the coordinates.
var x = Math.min(ev._x, tool.x0), y = Math.min(ev._y, tool.y0), w = Math.abs(ev._x - tool.x0), h = Math.abs(ev._y - tool.y0);
Now , I want to pass all the variables to my servlet where I want to do some calculations to get the coordinates of 4 corners:
top-left corner : (x , y) top-right corner: (x+w , y) bottom-left corner: (x , y+h) bottom-right corner: (x+w , y+h)
What can I do in order to get all the coordinates values ? Thanks.
