网页TWAIN扫描是通过多种技术结合实现的，看下流程图： 参考原文： Web-based Document Imaging Capture with .Net TWAIN and Jetty 准备工作 阅读： 如何通过jni4net，在Java应用中调用C#接口 使用Jetty搭建Java Websocket Server，实现图像传输 如何运行 在Eclipse中运行Java Application，选择UIMain 当这个窗口启动的时候，Websocket Server已经初始化完成。 Load：加载本地图片 Send：把图片推送到网页客户端 Scan：通过扫描仪扫描文件，把图像自动发送到网页客户端 在Chrome中选择一个扫描仪源 显示TWAIN扫描文件图像 TWAIN网页扫描流程解析 首先把所有相关的库(DLL & Jar)导入到Eclipse工程中： 结合准备工作中两篇文章的代码， 创建一个类 SourceManager ： package com.data; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.io.File; import java.util.ArrayList; import javatwain.DotNetScanner;

OrCAD Capture仿真步骤 自带库中没有器件模型的仿真步骤 1、新建工程 2、添加原理图到工程 3、从TI、AD等公司下载芯片的CIR文件 4、利用model editor模型编辑器，先将cir文件转为lib文件，再将lib文件转为olb文件；OLB文件即为可使用的器件模型 5、添加OLB文件所在路径到libraries器件库里面；或者将OLB文件添加到自带库的路径下（不要出现中文字符路径） 6、添加器件到原理图，开始画电路图 7、创建New Simulation，并命名。设置仿真相关参数。仿真模式，仿真时间，步长等 8、在仿真设置里将芯片的lib文件路径添加到Configurat Files下的Library中 8、开始仿真Run。 来源： https://www.cnblogs.com/igalaxy/p/11994459.html

Is there a way to listen to the mouse and keyboard events system-wide without taking these out of system queue? E.g. is there a way to set a demon, let's say, which would listen and report each and every keyboard and mouse event? It's not possible using pure Java. But you can use JNI (Java Native Interface), which is working on code written in C++ and natively compiled. So, this way you can write the Global KeyListener in C++ and let make Java use of it. There is an active project implementing this for Linux, OS X and Windows: http://code.google.com/p/jnativehook/ 来源： https://stackoverflow.com

I have to print the entire text of a text field into a picture. The reason is: I have to exchange messages with unsupported UTF-8 characters between Android and other web clients. By unsupported UTF-8 characters I mean missing fonts in Android (see this topic here ). I tried to use the direct way Bitmap b; EditText editText = (EditText) findViewById(R.id.editText); editText.buildDrawingCache(); b = editText.getDrawingCache(); editText.destroyDrawingCache(); which works like a charm until I have multiple lines: The solution captures only the text which is visible to the user instead of the

I'm a MATLAB beginner and I would like to know how I can acquire and save 20 images at 5 second intervals from my camera. Thank you very much. To acquire the image, does the camera comes with some documented way to control it from a computer? MATLAB supports linking to outside libraries . Or you can buy the appropriate MATLAB toolbox as suggested by MatlabDoug. To save the image, IMWRITE is probably the easiest option. To repeat the action, a simple FOR loop with a PAUSE will give you roughly what you want with very little work: for ctr = 1:20 img = AcquireImage(); % your function goes here
