How to write text on top of image in html5 canvas?

Displaying text on top of an image in HTML5 canvas is a common requirement for various applications, ranging from image editors to data visualizations. The HTML5 canvas provides a powerful and flexible way to render images and graphics, but adding text to the canvas requires a slightly different approach than adding shapes or lines. There are several methods to achieve this, and each method has its pros and cons. In this article, we will discuss a few different methods to write text on top of an image in HTML5 canvas.

Method 1: Using fillText() Method

To write text on top of an image in HTML5 canvas using the fillText() method, follow these steps:

const canvas = document.getElementById('myCanvas'); const ctx = canvas.getContext('2d');

const img = new Image(); img.src = 'path/to/your/image.png'; img.onload = function()  // draw image on the canvas ctx.drawImage(img, 0, 0); >

ctx.font = '30px Arial'; ctx.fillStyle = 'white'; ctx.fillText('Your text here', 50, 50);

The fillText() method takes three arguments: the text to be displayed, the x-coordinate where the text should start, and the y-coordinate where the text should start.

Here’s an example with more detail:

const canvas = document.getElementById('myCanvas'); const ctx = canvas.getContext('2d'); const img = new Image(); img.src = 'path/to/your/image.png'; img.onload = function()  // draw image on the canvas ctx.drawImage(img, 0, 0); // draw text on top of the image ctx.font = '30px Arial'; ctx.fillStyle = 'white'; ctx.textAlign = 'center'; ctx.fillText('Your text here', canvas.width / 2, canvas.height / 2); >

In this example, we’re centering the text horizontally and vertically by setting the textAlign property to ‘center’ and calculating the x and y coordinates based on the canvas dimensions.

Method 2: Using strokeText() Method

To write text on top of an image in HTML5 canvas using the strokeText() method, follow these steps:

const canvas = document.getElementById('myCanvas'); const ctx = canvas.getContext('2d');

const img = new Image(); img.src = 'path/to/image.png';

img.onload = function()  ctx.drawImage(img, 0, 0); >

ctx.font = '30px Arial'; ctx.fillStyle = 'white';

ctx.strokeText('Hello, world!', 50, 50);

The first argument of strokeText() is the text you want to write, the second and third arguments are the x and y coordinates where you want to start writing the text.

const canvas = document.getElementById('myCanvas'); const ctx = canvas.getContext('2d'); const img = new Image(); img.src = 'path/to/image.png'; img.onload = function()  ctx.drawImage(img, 0, 0); ctx.font = '30px Arial'; ctx.fillStyle = 'white'; ctx.strokeText('Hello, world!', 50, 50); >

Method 3: Using a Library (e.g. fabric.js)

var canvas = new fabric.Canvas('canvas');

fabric.Image.fromURL('path/to/image.jpg', function(img)  canvas.add(img); >);

var text = new fabric.Text('Hello, world!',  left: 100, top: 100, fill: 'white', fontSize: 30 >);

1. To position the text on top of the image, we set the text object’s stackingOrder property to a value greater than the image’s stacking order:

var canvas = new fabric.Canvas('canvas'); fabric.Image.fromURL('path/to/image.jpg', function(img)  canvas.add(img); >); var text = new fabric.Text('Hello, world!',  left: 100, top: 100, fill: 'white', fontSize: 30 >); text.stackingOrder = 1; canvas.add(text);

This will add an image to the canvas, and then add text on top of the image. You can customize the text properties as desired, such as changing the font, size, color, and position.

Position Text over an Image

First of all, we will add an image to our web page using HTML.

HTML

An image has been inserted in the web page.

Top left corner

The first position of the text where we are going to set is the top left corner of the image. Use the following code snippet.

CSS

The position of the first div element has been set to relative so that we can absolutely position the second div element. The text to be placed on the image has been given some size, weight, style, and color, meanwhile to position it on the top left corner we have used the top and left properties.

The text was successfully placed in the top left corner.

Bottom left corner

For the purpose of adding a text on the bottom left corner of the image use the code mentioned below.

CSS

The rest of the code is the same, however, to position the text on the bottom left corner we have set the bottom property to 3%, and left property to 8%. You can change the values of these properties to understand how these work.

The text was positioned on the bottom left corner with great ease.

Center

Similarly, to place your text in the center position, consider the below-mentioned example.

CSS

For the purpose of adjusting the text on the center position of the image we have set the top property and left property to 40%.

We have successfully placed the text at the center of the image

Top right corner

Consult the code below to understand how to place text on the top right corner of the image.

CSS

What we have simply done to place the text on the top right corner is that we have set top property to 2%, and right property to 10%. This is not a hard and fast rule, therefore, you can change these values according to your desire.

The text was inserted in the top right corner of the picture.

Bottom right corner

Last position that we are going to demonstrate is the bottom right corner of the image. Follow the code below.

CSS

As you can see that the rest of the code is the same as in previous examples with only difference that to place the text on the bottom right corner we have used the bottom property and the right property.

The text was placed at the bottom right corner.

Conclusion

To position your text over an image place your image and text inside a div container and absolutely position the text, meanwhile giving the div a relative position. Different positions that you can place your text over an image are the top left corner, bottom left corner, center, top right corner, and bottom right corner. This task can be performed using various CSS properties. In this post we have demonstrated each of these positions along with suitable examples.
