* return the location of the click (or another mouse event) relative to the given element (to increase accuracy). Now that we can get the location of the canvas, the following method will be the one that cares about the location of the click on the canvas (or another mouse event attached to the canvas) : /** When you say 'get the mouse position on click on the swing window itself' do you mean that you want to display it on the Swing window or do you just mean you want the coordinates of the pointer when the pointer is on the Swing window (btw I do think you mean pointer and not mouse). The previous method returns the location (an object with x and y coordinates) of the element given as first parameter (canvas in this case) in the document. * Return the location of the element (x,y) being relative to the document. This little tool introduced in this paper mainly USES MouseInfo to obtain real-time information of the mouse, and then displays it on JDialog. As one of the most popular computer development languages at present, java is a good choice for high-paying jobs. However this function will be internally used by the function that is going to retrieve the location of the click. java gets the mouse coordinates on the screen. Use the following function to retrieve the location of the element (in this case the canvas) , it expects the DOM element as first parameter. Let's get started ! Retrieving mouse location on eventĪs there are many possible errors and things that the user could do, we need to be exact as possible, therefore to guarantee that the mouse coordinates are reliable, we are going to retrieve them according to the location of the canvas.

Use the coordinates to select the data on the canvas.Retrieve the location of the mouse event.To retrieve the color from a pixel of a specific canvas, we are going to : This task is relatively easy to achieve using pure javascript without any kind of library. There are many utilities that you could create if you would be able to extract the color from a single pixel of a canvas, an interactive color picker etc.
