摘要： PROBLEM TO BE SOLVED: To solve a problem that a scanning system is likely to become unstable gradually because a couple of asynchronous drivers make access to the same hardware and software resources. SOLUTION: An expanded module is generated to operate in place of a TWAIN application through communication with a WIA driver via WIA service. A data structure is transmitted to the WIA driver from the expanded module via a custom property mechanism of the WIA service. The location of binary data file including an instruction data to the scanner can be identified with the WIA driver in accordance with the location included in the data structure. The instruction data is transmitted to the scanner, and the scanner processes the instruction data and returns the result of the process to the WIA driver. The WIA driver writes the result of process to a new binary data file. The data structure is updated and transmitted to the extended module to identify the location of the new binary data file.

解决方案：通过WIA服务与WIA驱动程序进行通信，生成扩展模块来代替TWAIN应用程序。数据结构通过WIA服务的定制属性机制从扩展模块传输到WIA驱动程序。可以根据包含在数据结构中的位置，通过WIA驱动器来识别包括扫描仪的指令数据的二进制数据文件的位置。指令数据被发送到扫描仪，扫描器处理指令数据并将处理结果返回给WIA驱动程序。 WIA驱动程序将进程的结果写入新的二进制数据文件。数据结构被更新并传输到扩展模块以识别新的二进制数据文件的位置。版权所有（C）2011，JPO＆INPIT
