WiaItemPropertyId

A maioria das constantes de propriedade wia (aquisição de imagem do Windows) são agrupadas em um tipo de dados enumerado, WiaItemPropertyId para autores de script.

A tabela a seguir apresenta o mapeamento entre as convenções de nomenclatura usadas no script e no C++. Por exemplo, no script, o prefixo "CameraDevice" é mapeado para o prefixo "WIA_DPC" para a constante C++ correspondente. Em um exemplo mais específico, a propriedade "CameraDeviceFlashMode" é equivalente à constante "WIA_DPC_FLASH_MODE" do C++. Consulte os tópicos de constante de propriedade correspondentes para obter descrições de cada propriedade.

Prefixo de script	Tópico C++ (prefixo)
Dispositivo	Constantes comuns de propriedade de dispositivo (WIA_DPA)
CameraDevice	Constantes de propriedade do dispositivo de câmera (WIA_DPC)
ScannerDevice	Constantes de propriedade do dispositivo scanner (WIA_DPS)
VideoDevice	Constantes de propriedade do dispositivo WIA de vídeo (WIA_DPV)
Picture	Constantes comuns de propriedade de item WIA (WIA_IPA)
CameraPicture	Constantes de propriedade de item WIA da câmera (WIA_IPC)
ScannerPicture	Constantes de propriedade de item WIA do scanner (WIA_IPS)

 

O exemplo a seguir fornece o tipo enumerado completo com os nomes correspondentes.
