Node Jimp | Gaussian
Introduction
The Gaussian() function is an inbuilt function in Nodejs | Jimp which applies a true Gaussian blur to the image but its processing is quite slow in comparison to other Jimp functions.
Syntax:
gaussian(r, cb)
Parameter:
- r – This parameter stores the pixel radius of the blur.
- cb – This is an optional parameter which is invoked when compilation is complete.
Input Images:
Example 1:
//npm install --save jimp //import jimp library to the environment var Jimp = require( 'jimp' ); //User-Defined Function to read the images async function main() { const image = await Jimp.read // invert function image.gaussian(5) .write( 'gaussian1.png' ); } main(); console.log( "Image Processing Completed" ); |

Example 2: With radius and cb (optional parameters)
//npm install --save jimp //import jimp library to the environment var Jimp = require( 'jimp' ); //User-Defined Function to read the images async function main() { const image = await Jimp.read //gaussian function using callback function image.gaussian(10, function (err){ if (err) throw err; }) .write( 'gaussian2.png' ); } main(); console.log( "Image Processing Completed" ); |
