What is Canvas?
The HTML5 canvas element can be used to draw graphics on the webpage via JavaScript. The canvas was originally introduced by Apple for the Mac OS dashboard widgets and to power graphics in the Safari web browser. Later it was adopted by the Firefox, Google Chrome and Opera. Now the canvas is a part of the new HTML5 specification for next generation web technologies.
By default the element has 300px of width and 150px of height without any border and content. However, custom width and height can be defined using the CSS
height
and width
property whereas the border can be applied using the CSS border
property.
Understanding Canvas Coordinates
The canvas is a two-dimensional rectangular area. Hacker (itch) (juangarcia) mac os. The coordinates of the top-left corner of the canvas are (0, 0) which is known as origin, and the coordinates of the bottom-right corner are (canvas width, canvas height). Here's a simple demonstration of canvas default coordinate system.
(0,0)
Html5 Canvas Reference
Tip: Place your mouse pointer within the canvas area demonstrated above and you will get its current coordinates relative to the canvas. The element is supported in all major web browsers such as Chrome, Firefox, Safari, Opera, IE 9 and above.
Drawing Path and Shapes on Canvas
In this section we're going to take a closer look at how to draw basic paths and shapes using the newly introduced HTML5 canvas element and JavaScript.
Here is the base template for drawing paths and shapes onto the 2D HTML5 canvas.
All the lines except those from 7 to 11 are pretty straight forward. The anonymous function attached to the window.onload
event will execute when the page load. Once the page is loaded, we can access the canvas element with document.getElementById()
method. Later we have defined a 2D canvas context by passing 2d into the getContext()
method of the canvas object.
Drawing a Line
The most basic path you can draw on canvas is a straight line. The most essential methods used for this purpose are moveTo()
, lineTo()
and the stroke()
.
The moveTo()
method defines the position of drawing cursor onto the canvas, whereas the lineTo()
method used to define the coordinates of the line's end point, and finally the stroke()
method is used to make the line visible. Let's try out an example:
Drawing a Arc
You can create arcs using the arc()
method. The syntax of this method is as follow:
The JavaScript code in the following example will draw an arc on the canvas.
Drawing a Rectangle
You can create rectangle and square shapes using the rect()
method. This method requires four parameters x, y position of the rectangle and its width and height.
The basic syntax of the rect()
method can be given with:
The following JavaScript code will draw a rectangle shape centered on the canvas.
Drawing a Circle
Html5 Canvas Pdf
There is no specific method for creating circle like rectangle's rect()
method. However, you can create a fully enclosed arc such as circle using the arc()
method.
The syntax for drawing a complete circle using the arc()
method can be given with:
The following example will draw a complete circle centered on the canvas.
Applying Styles and Colors on Stroke
The default color of the stroke is black and its thickness is one pixel. But, you can set the color and width of the stoke using the strokeStyle
and lineWidth
property respectivley.
The following example will draw an orange color line having 5 pixels width.
You can also set the cap style for the lines using the lineCap
property. There are three styles available for the line caps — butt, round, and square. Here's an example:
Filling Colors inside Canvas Shapes
You can also fill color inside the canvas shapes using the fillStyle()
method.
The following example will show you how to fill a solid color inside a rectangle shape.
Tip: While styling the shapes on canvas, it is recommended to use the fill()
method before the stroke()
method in order to render the stroke correctly.
Similarly, you can use the fillStyle()
method to fill solid color inside a circle too.
Filling Gradient Colors inside Canvas Shapes
You can also fill gradient color inside the canvas shapes. A gradient is just a smooth visual transition from one color to another. There are two types of gradient available — linear and radial.
The basic syntax for creating a linear gradient can be given with:
The following example uses the createLinearGradient()
method to fill a linear gradient color inside a rectangle. Let's try it out to understand how it basically works:
Similarly, you can fill canvas shapes with radial gradient using the createRadialGradient()
method. The basic syntax for creating a radial gradient can be given with:
The following example uses the createRadialGradient()
method to fill a radial gradient color inside a circle. Let's try it out to understand how it actually works:
Drawing Text on Canvas
You can also draw text onto canvas. These texts can contain any Unicode characters. The following example will draw a simple greeting message 'Hello World!' onto a canvas.
You can additionally set the color and alignment of the text on the canvas, like this:
You can also apply stroke on text using the strokeText()
method. This method will color the perimeter of the text instead of filling it. However if you want to set both the fill and stroke on canvas text you can use both the fillText()
and the strokeText()
methods together.
Tip: While styling the text on canvas, it is recommended to use the fillText()
method before the strokeText()
method in order to render the stroke correctly.
