HTML+CSS+JavaScript制作爱心代码
好的,以下是用 Node.js 写的爱心代码:
const canvas = require('canvas');
const fs = require('fs');
const Image = canvas.Image;
const heartImg = new Image();
heartImg.onload = function() {
const width = 200;
const height = 200;
const canvas = canvas.createCanvas(width, height);
const context = canvas.getContext('2d');
context.drawImage(heartImg, 0, 0, width, height);
const imageData = context.getImageData(0, 0, width, height);
const data = imageData.data;
for(let i = 0; i < data.length; i += 4) {
const red = data[i];
const green = data[i + 1];
const blue = data[i + 2];
const alpha = data[i + 3];
if(red === 255 && green === 255 && blue === 255 && alpha === 255) {
data[i] = 255;
data[i + 1] = 0;
data[i + 2] = 0;
}
}
context.putImageData(imageData, 0, 0);
fs.writeFile('heart.png', canvas.toBuffer(), function(err) {
if(err) throw err;
console.log('爱心已生成!');
});
};
heartImg.src = 'heart.png';
笑话:为什么程序员总是用麻雀写程序?因为他们总是想方设法让程序飞起来!
