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:
// 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:
Example 2: cb (optional parameters)
// 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/20190328185333/gfg111.png');
// color function having spin modifier
image.color([{ apply: 'spin', params: [50] }], function (err) {
if (err) throw err;
})
.write('spin2.png');
}
main();
