Enumeration Type Documentation

enum wxIAReturnCode

IA Return Codes.

Enumerator
wxIA_RC_SUCCESS	Operation completed successfully.
wxIA_RC_UNKNOWNERROR	Unknown error.
wxIA_RC_NOTSUPPORTED	Operation, mode, or value not supported.
wxIA_RC_CANCELLED	Operation was cancelled by user.
wxIA_RC_NOTREADY	Device is not ready.
wxIA_RC_DEVICEBUSY	Device is busy.
wxIA_RC_INVAL	Invalid data or argument.
wxIA_RC_JAMMED	Document feeder jammed.
wxIA_RC_NODOCS	Document feeder out of documents.
wxIA_RC_COVEROPEN	Scanner cover is open.
wxIA_RC_IOERROR	Error during device I/O.
wxIA_RC_NOMEM	Out of memory.
wxIA_RC_ACCESSDENIED	Access to resource has been denied.
wxIA_RC_NOSOURCE	No source selected.
wxIA_RC_NOTINITIALIZED	Provider not initialized.

enum wxIASourceType

IA Source Types.

Specifies the type of device encapsulated by the source.

Enumerator
wxIA_SOURCE_UNKNOWN	Unknown.
wxIA_SOURCE_SCANNER	Generic scanner - exact type is unknown, but it is a scanner.
wxIA_SOURCE_FLATBEDSCANNER	Flatbed scanner.
wxIA_SOURCE_FILMSCANNER	Film scanner.
wxIA_SOURCE_STILLCAMERA	Still camera.
wxIA_SOURCE_VIDEOCAMERA	Video camera.
wxIA_SOURCE_FILE	Image file.
wxIA_SOURCE_IMAGEBASE	ImageBase - Image data base.
wxIA_SOURCE_FRAMEGRABBER	Frame grabber.
wxIA_SOURCE_MULTIFUNCTION	Multifunction device - fax/scanner/printer etc.
wxIA_SOURCE_SHEETFEDSCANNER	Sheetfed scanner.
wxIA_SOURCE_HANDHELDSCANNER	Handheld scanner.

enum wxIATransferFileType

Image transfer file type.

Enumerator
wxIA_FILETYPE_JPG	JPG - JPEG.
wxIA_FILETYPE_TIFF	TIFF.
wxIA_FILETYPE_BMP	BMP - Windows/OS2 bitmap.

enum wxIATransferMode

Source Image Transfer Mode.

Mode used to transfer image data from the source.

Enumerator
wxIA_TRANSFERMODE_NATIVE	Native image transfer mode. Image data will be supplied as both wxBitmap and wxImage. For TWAIN the native mode supplies DIB and for Mac OS the native mode supplies a PICT. No matter what native format is actually used, the user will retrieve the data as a wxBitmap or wxImage.
wxIA_TRANSFERMODE_BUFFER	Transfer raw data a buffer at a time. Image data will be transfered to a user supplied buffer using as many transfers as necessary.
wxIA_TRANSFERMODE_FILE	Transfer image data by storing data in a file.

enum wxIAUIMode

User Interface Mode.

Mode of the user interface presented

Enumerator
wxIA_UIMODE_NONE	No user interface if possible.
wxIA_UIMODE_NORMAL	Normal user interface. Provides a dialog or whatever is appropriate.
