const writeStream.getColorDepth([env])
参数:该方法接受包含环境变量的对象作为参数。
返回值:该方法返回该终端支持的颜色数。
示例 1: 文件名:index.js
// Node.js program to demonstrate the
// writeStream.getColorDepth() method
// Importing dgram module
var dgram = require('dgram');
// Creating and initializing client
// and server socket
var client = dgram.createSocket("udp4");
var server = dgram.createSocket("udp4");
// Handling the message event
server.on("message", function (msg) {
// Creating and initializing a
// WriteStream object
let WriteStream = process.stdout;
// Getting color depth
// by using getColorDepth() API
const col = WriteStream
.getColorDepth(process.env);
// Displaying the result
process.stdout.write(msg + col);
// Exiting process
process.exit();
})
// Binding server with port
.bind(1234, () => {
});
// Client sending message to server
client.send("No of color supported is :- ",
0, 28, 1234, "localhost");
输出:
No of color supported is :- 24
示例 2:文件名:index.js
// Node.js program to demonstrate the
// writeStream.getColorDepth() method
// Creating and initializing a
// WriteStream object
let WriteStream = process.stdout;
// Getting color depth
// by using getColorDepth() API
const col = WriteStream.getColorDepth(process.env);
// Displaying the result
console.log("No of color supported is :- " + col);
使用以下命令运行 index.js 文件:
node index.js
输出:
No of color supported is :- 24
