Github:https://github.com/zhangyuanwei/node-images

Features Functional characteristics

• Lightweight: No need to install any image processing libraries.
• Cross-platform: a compiled. node file is released under Windows and can be downloaded.
• Easy to use: jquery-style API, simple to rely on.

What can we do with this plugin, the common watermark can be added, simple amplification and compression processing.

Instance:

//encode picture dependent module https://github.com/zhangyuanwei/node-imagesvarImages = require ("Images");varFS = require ("FS");varPath = require ("Path"); function ReadFile (SRC,DST) {//To determine if the file takes time, you must synchronize    if(Fs.existssync (src)) {//Read FolderFs.readdir (src,function (err,files) {if(err) {Throwerr;                                } Files.foreach (function (FilePath) {console.log (DST); //url+ "/" +filename not available/direct connection, UNIX system is "/", Windows system is "\"                varURL =Path.join (Src,filepath), dest=Path.join (Dst,filepath); Fs.stat (Url,function (err,stats) {if(ERR)Throwerr; //is a file                    if(Stats.isfile ()) {//The regular verdict is the picture                        if(/.*\.
