How does it work?
UniTwain is a virtual scanner which appears in your application just like any other
scanning device. By scanning from it, the UniTwain interface will appear, which allows you to
import documents, images, snapshots from cameras, and even scans from other scanners, and
then returns all those images back to the application. This enables you to scan any type of
document directly into your application.

If you choose a flatbed ADF scanner, you can choose between: flatbed, ADF and auto source. ADF
means your scanner has a slot where you put your documents to scan. This way you get your
documents scanned one after another from the scanner slot. For example, ADF source is very
useful when your documents are bounded. Otherwise, if you select flatbed source then you will
have to manually change documents on your scanner. Auto source will automatically adjust
source for you.
Page size

Color type
Next option to choose from is the color type. Color types depend on the selected scanner. In our
example we have four color types: BW, Grey, RGB and Palette. BW means your document will
result in black and white. The RGB color model is an additive color model in which red, green, and
blue light are added together in various ways to reproduce a broad array of colors. The name of
the model comes from the initials of the three additive primary colors, red, green, and blue.
