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.

Example

In this example, user chooses desired scanning tool and then selects UniTwain sourcefrom the “Select Source” tab.

Furthermore, you can choose data transfer type between “Memory” type and “Native” type.

Memory type scans directly to the computer’s memory. Native type scans directly to the file and

is considered to be more compatible with wider variety of scanners.

Source

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

Same as in the “Source” section, number of options in “Page size” selection box will depend onthe selected scanner. All pages sizes your scanner supports are available for you to choose.

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.
