1.1.3.1 Primary Features

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 Scanner button on the Add To Case screen. Figure 12 shows the initial Scanner screen. Table 7 shows the buttons on the Scanner screen and describes their functions.

Function

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.
