Getting Java and TWAIN to play together nicely
提问by jacobko
I'm working on building an app to scan directly from TWAIN scanner to a Java applet. I'm already aware of Morenaand JTwain, but they cost money. I need free. I could re-invent the wheel with JNI, but it seems like someone has probably already done this as a FOSS tool.
我正在构建一个应用程序以直接从 TWAIN 扫描仪扫描到 Java 小程序。我已经知道Morena和JTwain，但他们花钱。我需要免费。我可以用 JNI 重新发明轮子，但似乎有人可能已经将其作为 FOSS 工具完成了。
Is anyone familiar with a freetool that can get a Java applet to read directly from a TWAIN scanner?
有没有人熟悉可以让 Java 小程序直接从 TWAIN 扫描仪读取的免费工具？

Calling the TWAIN API from anything except C/C++ is going to be a major pain, it relies entirely on complicated C structures that you have to replicate exactly in memory. If you need only fairly basic scanning, you could use something like GitHub siteto call my old free 'EZTwain Classic' DLL (google for eztw32.dll)
从 C/C++ 之外的任何东西调用 TWAIN API 将是一个主要的痛苦，它完全依赖于复杂的 C 结构，您必须在内存中精确复制。如果你只需要相当基本的扫描，你可以使用类似GitHub 站点的东西来调用我旧的免费“EZTwain Classic”DLL（谷歌搜索 eztw32.dll）

I've actually purchased the chestysoft activeX control. Been using it for about 3 years. Works great but as with all ActiveX you are restricted to IE. And this one is 32-bit only. I'm looking into a flash approach now. Since flash can capture from a camera why not from a scanner. If I remember I'll report back what I find.
我实际上已经购买了chestysoft activeX 控件。已经使用它大约 3 年了。效果很好，但与所有 ActiveX 一样，您只能使用 IE。而这个只有 32 位。我现在正在研究一种闪存方法。既然闪光灯可以从相机捕捉，为什么不能从扫描仪捕捉。如果我记得，我会报告我的发现。
