Node Jimp | Color spin
The spin modifier is an inbuilt color modifier in Nodejs | Jimp that spins the hue of an image to a given amount, from -360 to 360. Spinning to 0, 360, and -360 will not perform any function since it sets the hue back to what it was before.
Syntax:
image.color([ { apply: 'spin', params: [value] } ]);
Parameter:
- value – This parameter stores the amount of hue spin to apply. It takes values from -360 to 360.
Input Images:

// 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 ( 'https://media.w3wiki.net/wp-content/uploads/20190328185307/gfg28.png' ); // color function having spin modifier image.color([{ apply: 'spin' , params: [50] }]) .write( 'spin1.png' ); } main(); console.log( "Image Processing Completed" ); |
