Before proceeding to use sepia() functions, please check that the following statements are already executed for setting up the environment.

  • Create a sepia.js file and copy-paste the following code snippet in it.

  • Use node sepia.js to run the code.

Note: – The method name should match with the JS file name. Only then, it will be able to call the desired method.

async function sepia() {
   // Reading Image
   const image= await Jimp.read
   ('/home/jimp/tutorials_point_img.jpg');
   image.sepia()
   .write('/home/jimp/sepia.jpg')
}

sepia(); // Calling the function here using async
console.log("Image is processed successfully");
