带有 Flex/Java 小程序的 USB 扫描仪? [英] USB Scanner with Flex / Java applet?

问题描述

有没有办法从 USB 扫描仪获取图像(主要在 Windows 上，跨平台解决方案是最好的)并将图像一起发布到带有 Flex 或 Java 小程序的浏览器中的表单中?

Is there a way to get an image from a usb scanner (on Windows primarily, cross-platform solution would be best) and post the image together to a form in browser with Flex or Java applet?

谢谢！

推荐答案

标准化的 TWAIN 扫描接口绝对是你看的地方，而不是低级的 USB，除非你只针对一个特定的设备并且知道如何与之交谈.

The standardized TWAIN scanning interface is definitely the place for you to look at, rather than low-level USB, except if you are targeting only one specific device and know how to talk to it.

基于Java

另一个堆栈溢出问题指出了指向一个打开的 Applet 与 TWAIN 设备对话.如果您希望不花钱，而是自己构建它，这可能是一个起点.

There is another Stack Overflow question pointing out a link to a open Applet talking to a TWAIN device. If you're looking to spend no money, and build it yourself, that is maybe a starting point.

市场上我能看到的唯一现成的商业产品是JTwain.我手边没有任何 TWAIN 设备可供测试，但它看起来不错.

The only ready-made commercial product on the market that I can see is JTwain. I don't have any TWAIN devices handy to test, but it looks good.

TWAIN 似乎是 到 Linux 也是如此，商业产品的制造商承诺在未来支持其他平台.

TWAIN seems be on its way to Linux as well, and the makers of the commercial product promise support for other platforms in the future.

Active X/基于插件

至少有 一个产品在仅限 Windows 的 ActiveX 上连接 Twain/Browser 插件基础，号称支持所有主流浏览器.提供 30 天试用版.

There is at least one product connecting Twain on a Windows-only, ActiveX/Browser plugin basis, claiming to support all major browsers. A 30-day trial version is available.
