WiaItemPropertyId

La mayoría de las constantes de propiedades de adquisición de imágenes de Windows (WIA) se agrupan en un tipo de datos enumerado, WiaItemPropertyId para los autores de scripting.

En la tabla siguiente se presenta la asignación entre las convenciones de nomenclatura usadas en scripting y C++. Por ejemplo, en el script, el prefijo "CameraDevice" se asigna al prefijo "WIA_DPC" para la constante de C++ correspondiente. En un ejemplo más específico, la propiedad "CameraDeviceFlashMode" es equivalente a la constante "WIA_DPC_FLASH_MODE" de C++. Consulte los temas de constantes de propiedad correspondientes para obtener descripciones de cada propiedad.

Prefijo de script	Tema de C++ (prefijo)
Dispositivo	Constantes comunes de propiedad de dispositivo (WIA_DPA)
CameraDevice	Constantes de propiedad del dispositivo de cámara (WIA_DPC)
ScannerDevice	Constantes de propiedad del dispositivo del escáner (WIA_DPS)
VideoDevice	Constantes de propiedad de dispositivo WIA de vídeo (WIA_DPV)
Imagen	Constantes comunes de propiedades de elemento WIA (WIA_IPA)
CameraPicture	Constantes de propiedad de elemento WIA de cámara (WIA_IPC)
ScannerPicture	Constantes de propiedad de elemento WIA del escáner (WIA_IPS)

 

En el ejemplo siguiente se proporciona el tipo enumerado completo con los nombres correspondientes.
