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:

Example 1:

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
('https://media.geeksforgeeks.org/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");

Output:
