节点吉普 |颜色异或
介绍
xor修饰符是 Nodejs 中内置的颜色修饰符 | Jimp 将两种颜色视为位域,并对给定图像的红色、绿色和蓝色分量应用 XOR 运算。
image.color([
{ apply: 'xor', params: value }
]);
范围:
- value – 此参数存储要应用 xor 操作的颜色。
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 xor modifier
image.color([{apply:'xor', params: ['green']}])
.write('xor1.png');
}
main();
console.log("Image Processing Completed");
输出:
示例 2:cb(可选参数)
// 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/20190328185333/gfg111.png');
// color function having xor modifier
image.color([{apply:'xor', params: ['blue']}], function(err){
if (err) throw err;
})
.write('xor2.png');
}
main();
console.log("Image Processing Completed");
