Node Jimp | Color spin
Introduction
The spin modifier is an inbuilt color modifier in Nodejs | Jimp which spin the hue of an image to a given amount, from -360 to 360. Spinning to 0, 360, -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 var Jimp = require( 'jimp' ); // User-Defined Function to read the images async function main() { const image = await Jimp.read // 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 var Jimp = require( 'jimp' ); // User-Defined Function to read the images async function main() { const image = await Jimp.read // color function having spin modifier image.color([{apply: 'spin' , params: [50]}], function (err){ if (err) throw err; }) .write( 'spin2.png' ); } main(); console.log( "Image Processing Completed" ); |
