节点吉普 |色调

介绍
tint修饰符是 Nodejs 中内置的颜色修饰符 | Jimp 将白色混合到图像中。
句法:

  { apply: 'tint', params: value }
]);

范围:

  • value – 此参数存储要应用的色调量。

输入图像:

示例 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
('https://media.geeksforgeeks.org/wp-content/uploads/20190328185307/gfg28.png');
// color function having tint modifier
  image.color([{apply:'tint', params: [60]}])
  .write('tint1.png');
} 
  
main();
  console.log("Image Processing Completed");
