ImageGear .NET - Updated
ImageGear.TWAIN Namespace
Inheritance Hierarchy
ImageGear23.Twain Assembly : ImageGear.TWAIN Namespace

The ImageGear TWAIN namespace (available in ImageGear .NET 32-bit only) allows you to control any scanner, digital camera, or capture card that has a TWAIN device driver.

Classes
 ClassDescription
ClassImGearCap This is a base class for the capability classes.
ClassImGearCapArray This class describes a capability whose value resides in ImGearContainerType.ARRAY container.
ClassImGearCapEnumeration This class describes a capability whose value resides in an ImGearContainerType.ENUMERATION container.
ClassImGearCapOneValue This class describes a capability whose value resides in ImGearContainerType.ONEVALUE container.
ClassImGearCapRange This class describes a capability whose value resides in ImGearContainerType.RANGE container.
ClassImGearDataSources This class holds information about TWAIN data sources.
ClassImGearFileInfo This class holds information about TWAIN file system.
ClassImGearTWAIN Core TWAIN class.
ClassImGearTWAINAfterPageEventArgs Contains arguments for the ImGearTWAIN.AfterPage event.
ClassImGearTWAINBeforePageEventArgs Contains arguments for the ImGearTWAIN.BeforePage event.
Delegates
 DelegateDescription
DelegateImGearTWAINAfterPageEventHandler This is the delegate used to pass ImGearTWAIN.AfterPage events on to an application event handler.
DelegateImGearTWAINBeforePageEventHandler This is the delegate used to pass ImGearTWAIN.BeforePage events on to an application event handler.
Enumerations
 EnumerationDescription
EnumerationImGearAlarms This enumeration determines specific audible alarms.
EnumerationImGearAudioFormats This enumeration determines which Audio file formats are supported.
EnumerationImGearBarcodeRotation The bar code's orientation on the scanned image.
EnumerationImGearBarcodeSearchModes This enumeration restricts barcode searching to certain orientations, or prioritizes one orientation over the other.
EnumerationImGearBarcodeType This enumeration lists different bar code types.
EnumerationImGearBitDepthReduction This enumeration specifies the Reduction method the Source should use to reduce the bit depth of the data.
EnumerationImGearBitOrder This enumeration specifies how the bytes in an image are filled by the Source.
EnumerationImGearCapabilities Supported capabilities.
EnumerationImGearClearBuffers This enumeration determines the type of buffer clearing process.
EnumerationImGearColorDataFormats This enumeration allows the application and Source to identify which color data formats are available.
EnumerationImGearContainerType Capability container type. Defines how the data for a capability is stored.
EnumerationImGearCountries Country constants.
EnumerationImGearDeskewStatus Status of the deskew operation.
EnumerationImGearDeviceEvents This enumeration determines the device event.
EnumerationImGearDuplex This enumeration determines whether the scanner supports duplex.
EnumerationImGearFeederAlignment This enumeration determines which special actions application may need to take when negotiating frames with the Source.
EnumerationImGearFeederOrder This enumeration determines the order of scanning.
EnumerationImGearFileSystem This enumeration is for an undocumented TWAIN 1.8 capability.
EnumerationImGearFileType File types in the device's file system.
EnumerationImGearFilterType This enumeration determines the color characteristic of the subtractive filter applied to the image data.
EnumerationImGearFlashUsed This enumeration determines which flash the image was acquired to use.
EnumerationImGearFlipRotation This enumeration determines the orientation of images that flip orientation of every other image.
EnumerationImGearImageFilter This enumeration determines the algorithm used to improve the quality of the image.
EnumerationImGearJobControl This enumeration determines how the job can be processed.
EnumerationImGearJPEGQuality This enumeration specifies the kind of JPEG quantization tables that tradeoff quality versus compressed image size.
EnumerationImGearLanguages Language constants.
EnumerationImGearLightPath This enumeration determines whether the image is captured transmissively or reflectively.
EnumerationImGearLightSource This enumeration determines the general color characteristic of the light source used to acquire the image.
EnumerationImGearMessages Capability control messages.
EnumerationImGearNoiseFilter This enumeration selects the algorithm used to remove noise.
EnumerationImGearOrientation This enumeration determines which edge of the paper the image's top is aligned with.
EnumerationImGearOverscanModes This enumeration determines the overscanning mode.
EnumerationImGearPatchCode This enumeration lists different patch code types.
EnumerationImGearPixelFlavor This enumeration correctly describes the sense of the pixel whose numeric value is zero (minimum data value).
EnumerationImGearPixelType This enumeration specifies the type of pixel data that a Source is capable of acquiring (for example, black and white, gray, RGB, etc.).
EnumerationImGearPowerSupply This enumeration reports the kinds of power available to the device.
EnumerationImGearPrinter This enumeration determines the printer devices being used by application.
EnumerationImGearPrinterModes This enumeration specifies current printer mode.
EnumerationImGearSupportedSizes This enumeration specifies the size(s) the Source can/should use to acquire image data.
EnumerationImGearUnits This enumeration determines the unit of measure for all quantities.
EnumerationImGearXferType This enumeration determines which type of transfer mechanisms the application and Source have in common.
