The blur() function is an inbuilt function in Nodejs | Jimp which uses a blur algorithm that produces a similar effect to a Gaussian blur. 

Syntax: 

blur(r, cb())

Parameter: 

  • r: This parameter stores the radius of the blur.
  • cb: This is an optional parameter that is invoked when compilation is complete.

Input Images: 

Setup Environment: 

npm init -y

Example 1: In this example, we will see the use of the blur effect in the image.

javascript

// npm install --save jimp
// import jimp library to the environment
const Jimp = require('jimp');
 
// User-Defined Function to read the images
async function main() {
    const image = await Jimp.read('
        image.blur(5)
            .write('blur1.png');
}
main();
console.log('Image Processing Completed');

                    

Output:

        image.blur(2, function (err) {
            if (err) throw err;
        })
