WiaItemPropertyId

大部分的 Windows Image Acquisition (WIA) 屬性常數會分組在一個列舉資料類型中，WiaItemPropertyId 用於腳本作者。

下表顯示腳本和 C++ 中使用的命名慣例之間的對應。 例如，在腳本中，「CameraDevice」 前置詞會對應至對應 C++ 常數的 「WIA_DPC」 前置詞。 在更具體的範例中，「CameraDeviceFlashMode」 屬性相當於 C++ 「WIA_DPC_FLASH_MODE」 常數。 如需每個屬性的描述，請參閱對應的屬性常數主題。

腳本前置詞	C++ 主題 (前置詞)
裝置	通用裝置屬性常數 (WIA_DPA)
CameraDevice	數位相機裝置屬性常數 (WIA_DPC)
ScannerDevice	掃描器裝置屬性常數 (WIA_DPS)
VideoDevice	影片 WIA 裝置屬性常數 (WIA_DPV)
Picture	常見的 WIA 專案屬性常數 (WIA_IPA)
CameraPicture	相機 WIA 專案屬性常數 (WIA_IPC)
ScannerPicture	掃描器 WIA 專案屬性常數 (WIA_IPS)

 

下列範例會提供具有對應名稱的完整列舉型別。
