CONTENTS GLOSSARY INDEX Chapter 3 Scanning 16 Chapter 3 Scanning About Scanning Scanning is the process of converting an image into computer-usable information that is, digitizing the image. Scanners and digital cameras are the main examples of devices that have the technology to transfer an external image to digital information that can be saved as a file, printed, faxed, or otherwise manipulated on your computer. Until the introduction of digital cameras, scanners were the usual means of turning a photograph or other printed graphic into computer compatible information. Digital cameras use a similar process. Instead of exposing the image in its lens to photoreactive film, the shape, color and shading information is translated to a computer file. ScanGear CS-S lets you manipulate the digital information before the image is saved or sent to its final destination. Using ScanGear CS-S with an Application ScanGear CS-S is an interface between the scanner hardware and an imaging application on your computer. With ScanGear CS-S, you can scan images directly into an application without any interaction, or you can preview the image and make changes to the way the scan is performed that affect the resulting image. You can also scan printed text and, when the Text Enhanced feature is enabled, help your optical character recognition (OCR) software to recognize text more effectively. The TWAIN Interface ScanGear CS-S is TWAIN-compliant. TWAIN refers to the set of standards that define how information should be passed from image acquisition devices such as scanners to software imaging applications that have the ability to import TWAIN-compliant scanned images. A graphics application is a typical example of a program that supports TWAIN drivers. When you have a TWAIN-compliant application, scanner, and scanner driver, you can scan an image directly into that application. 16

About Scanning
Scanning is the process of converting an image into computer-usable
information that is,
digitizing
the image. Scanners and digital cameras are the
main examples of devices that have the technology to transfer an external
image to digital information that can be saved as a file, printed, faxed, or
otherwise manipulated on your computer.
Until the introduction of digital cameras, scanners were the usual means of
turning a photograph or other printed graphic into computer compatible
information. Digital cameras use a similar process. Instead of exposing the
image in its lens to photoreactive film, the shape, color and shading
information is translated to a computer file. ScanGear CS-S lets you
manipulate the digital information before the image is saved or sent to its
final destination.
Using ScanGear CS-S with an Application
ScanGear CS-S is an interface between the scanner hardware and an imaging
application on your computer. With ScanGear CS-S, you can scan images
directly into an application without any interaction, or you can preview the
image and make changes to the way the scan is performed that affect the
resulting image.
You can also scan printed text and, when the Text Enhanced feature is
enabled, help your optical character recognition (OCR) software to recognize
text more effectively.
The TWAIN Interface
ScanGear CS-S is TWAIN-compliant. TWAIN refers to the set of standards that
define how information should be passed from image acquisition devices such
as scanners to software imaging applications that have the ability to import
TWAIN-compliant scanned images.
A graphics application is a typical example of a program that supports TWAIN
drivers. When you have a TWAIN-compliant application, scanner, and scanner
driver, you can scan an image directly into that application.
