I bought 2 each of 50" and 34." Each piece was just a couple bucks. (Or you can cover an existing blank stretched canvas, but it will get pricey if you go very big.)Īt my local art store the wood strips were standing in bins, available in lengths all the way from super short to too long to manage. The wood strips have corners designed to interlock. Go to your local art supply store and buy 4 lengths of wood frame made for stretching canvas.

#Sew art canvas code
Place the following JavaScript code in a file named bouncingball.js. This gives the illusion that the ball is moving continuously.
#Sew art canvas update
It will clear the entire canvas and update x and y coordinates of the ball. In our case, a custom draw() function will be called every ten milliseconds. So, to make an object move on canvas you need to call a function periodically that clears the canvas and updates the position of the object. We already know that whatever you draw on canvas persists until you clear it. We will use the setTimeout() function to create the animation. You need to catch the ball with a paddle when it reaches the bottom of the screen. This example will create an application containing a bouncing ball. Var img = document.getElementById("myimage") įor a complete tutorial about drawing basic shapes you can refer to the Mozilla Developer Network documentation. var ctx = document.getElementById("canvasDemo").getContext("2d") In JavaScript we can access it by id and draw it as shown below. var ctx = document.getElementById("canvasDemo").getContext("2d") Īnother way is to add an image to your document and make it invisible. You can create an Image object and draw it on the canvas as shown below. Finally, the direction parameter denotes, whether the arc should be drawn clockwise or counterclockwise.ĭrawing an image on canvas is pretty easy. Therefore, you should use the Math.PI constant to convert from degrees. Note that the angles should be specified in radians. For a semi circle it should be 180 degrees.

While drawing a circle you will set this to 360 degrees. The endAngle determines the angle at which the arc ends. startAngle represents the starting angle for the arc. The first two parameters represent the center’s coordinate. arc(x,y,radius,startAngle,endAngle,direction) Drawing ArcsĪn arc is drawn using the arc() function, shown below. The first example in this article draws a line in this fashion. To draw a line you need to first call moveTo(), which represents the starting point of line. The method takes two parameters which represent the coordinates of the end point. Lines can be drawn using the lineTo() function. clearRect() clears a rectangular portion from the canvas, and strokeRect() draws a rectangular outline whose color is determined by the context.strokeStyle property. The modified canvas is shown in the following figure.Īs you can see, the fillRect() method creates a rectangle and fills it with the color specified by the context.fillStyle property. var canvas=document.getElementById("canvasDemo") As a result if you want to alter anything on the canvas, you will probably have to redraw the whole thing. It should be noted that elements do not maintain any DOM. The code draws a straight line from coordinate (30, 40) to (145, 120), with the upper left corner of the canvas acting as coordinate (0, 0). The following example shows how to draw a line on the canvas. From JavaScript we can access the element as shown below. This acts as a fallback for older browsers. Whatever you write inside the tag will appear if the browser does not support canvases. The height and width attributes are used to size the canvas. The id attribute is used so that we can access the element from JavaScript. Sorry, your browser does not support canvas. Current versions of Mozilla Firefox, Chrome, Opera, Safari, and IE 9 and 10 all support the element. Now it has been adopted by every major browser.

In this tutorial you will learn about some of the basic operations supported by the element and create a simple animation using JavaScript.Ĭanvas was first introduced by Apple in 2004 for use in Mac OS X and Safari.

The element, introduced in HTML5, allows developers to dynamically create bit map graphics using JavaScript.
