TWAIN Scanning

Another technique for loading an ImGearPage Class object involves obtaining the image from a device, like a scanner or a camera. ImageGear supports the acquisition of images from TWAIN-compliant devices.

ImageGear supports TWAIN 2.4 and all previous versions, working with a wide variety of scanner devices, digital cameras, and video capture boards. No TWAIN toolkit is easier or more comprehensive.

ImageGear includes a wide array of methods, providing the developer with detailed control of the scanning process, including control of the following:

TWAIN version
TWAIN transfer mode
Available TWAIN device listing
Scanning area
Brightness and contrast
Dots-per-inch (resolution)
Display of the TWAIN UI
Setting an event to gain control during scanning
ADF (Automatic Document Feeder) for multi-page scanning
Scanner capabilities

For a complete description of how to use ImageGear TWAIN namespace, see the ImageGear.TWAIN Namespace API Reference.

The ImageGear.TWAIN Namespace is available in both 32-bit and 64-bit ImageGear .NET.

Setting the version of TWAIN to 1 supports only 32-bit.
To switch between versions change the value of the DSMVersion enum to 0, 1, or 2, with 0 being the latest version available, 1 being version 1.x, and 2 being version 2.x.
