1.1.3 Scanner Features in the AFHCAN Software

The AFHCAN software provides a means for activating the TWAIN driver and for handling the

image that the TWAIN driver returns. To scan an image, press the

To Case screen. Figure 12 shows the initial Scanner screen. Table 7 shows the buttons on the

Scanner screen and describes their functions.

Button

Pressing the Scan button activates the TWAIN driver and initiates a scan.

The Scan button is used for scanning documents where a high-contrast,

black-and-white image is desired. When the Scan button is used to initiate a

scan, the software forces each pixel in the image to either 100% black or

100% white. This enhances the contrast for documents like forms, but

removes shading information needed for photographic images. The resulting

image file will be somewhat compressed, meaning it requires less memory and

takes less time to send and receive. The Scan button can be pressed

repeatedly to scan additional items. Each scan will be stored as a thumbnail

on the Scanner page.
