WiaItemPropertyId
大多数 Windows 映像获取 (WIA) 属性常量分组到一个枚举数据类型 WiaItemPropertyId 中，供脚本作者使用。
下表显示了脚本编写中使用的命名约定与 C++ 之间的映射。 例如，在脚本中，“CameraDevice”前缀映射到相应 C++ 常量的“WIA_DPC”前缀。 在更具体的示例中，“CameraDeviceFlashMode”属性等效于 C++ “WIA_DPC_FLASH_MODE” 常量。 有关每个属性的说明，请参阅相应的属性常量主题。
| 脚本前缀 | C++ 主题 (前缀) |
|---|---|
| 设备 | 常见设备属性常量 (WIA_DPA) |
| CameraDevice | 相机设备属性常量 (WIA_DPC) |
| ScannerDevice | 扫描程序设备属性常量 (WIA_DPS) |
| VideoDevice | 视频 WIA 设备属性常量 (WIA_DPV) |
| 图片 | 常见的 WIA 项属性常量 (WIA_IPA) |
| CameraPicture | 相机 WIA 项属性常量 (WIA_IPC) |
| ScannerPicture | 扫描程序 WIA 项属性常量 (WIA_IPS) |
以下示例提供具有相应名称的完整枚举类型。
