Window 7 64 位附带的 twain.dll 实现哪个版本的 TWAIN 规范？
我正在尝试确定我可以编写要使用的软件的 TWAIN 规范版本，并想找出 Win7 x64 附带的 twain.dll 实现的规范版本。文件信息如下：
File Version: 1.7.0.0
Product Name: Twain Source Manager
Product Version: 1,7,0,0
Size: 92.5KB
Date Modified: 6/10/2009 5:41 PM
我是否正在查看正确的文件来确定这一点？
TIA

Am I even looking at the correct file to determine this?
TIA

如果您想要 Windows 7 的 64 位版本，您需要从 Source Forge 获取最新版本，截至撰写本文时为 2.1 版本，

和

Microsoft 的人员只是觉得有一段时间没有必要更新他们与 Windows 捆绑的驱动程序版本。所以发布的版本相当旧，而且只有 32 位。
If you want to have a 64bit version for windows 7 you'll need to grab the latest off of source forge which as of this writing is the 2.1 version,
http://sourceforge.net/projects/twain-dsm/
and
http://sourceforge.net/projects/twain-samples/
The folks at Microsoft just haven't felt the need to update the version of the driver that they bundle with windows in some time. So the one that's gets shipped is quite old, and only 32bit.
