Software

Windows® 95, Windows® 98 or Windows NT® 4.0 is required to run the

ScanGear CS-S. It is also recommended that you install the latest available

Windows 95/98 or Windows NT 4.0 Service Pack.

About ScanGear CS-S

ScanGear CS-S has a number of powerful features that help you get the most out of your scanner’s capabilities. Using ScanGear CS-S, you can preview an image and make changes before the image is scanned and acquired by the application you are using.

Feature List

The following list describes some of ScanGear CS-S’s features:

• Flexible, fully automatic image acquisition, and pre-scan image manipulation prior to passing data to the image application

• Sophisticated, Windows-compliant user interface

• Full support of TWAIN 1.6 specifications

• Support for Automatic Document Feeder (ADF) option

• Text Enhanced mode for OCR(optical character recognition) applications

• Canon ColorGearTM Color Matching software technology

About ScanGear CS-S “Windowless” Mode

The ScanGear CS-S data source runs with or without its window (user interface, or UI) displayed, depending on the acquiring application. When an application requests a scan and the ScanGear CS-S window does not appear before the scan occurs, you can not use the ScanGear CS-S settings described in this manual. The host application provides the settings, and you can change the image after it is acquired. This is called “windowless” or “UI-less” scanning mode.

Selecting ScanGear CS-S

ScanGear CS-S can be called from any TWAIN-compliant application, such as an imaging or OCR application.

Because the TWAIN-compliant application may install older TWAIN files than ScanGear CS-S’s, it is recommended that the application be installed first, before ScanGear CS-S.

If you have installed other TWAIN drivers on your computer, you may select it as your default TWAIN source by using the application’s ‘File/Acquire/Select TWAIN_32 Source’ menu option or its equivalent. Once you have selected ScanGear CS-S as your source, choosing the command to scan, such as ‘File/ Acquire’, or ‘File/Scan’ will automatically start ScanGear CS-S in the application.

Removing ScanGear CS-S

If you need to remove ScanGear CS-S from your system, use the following steps to make sure all files are removed from all locations. Refer to the Quick Start Guide for instructions.

Where to Go From Here

Now that your ScanGear CS-S is installed and your scanner is ready to run, you can start scanning or read more about scanning techniques. ScanGear CS-S is easy to use, but more help is available if you need it.

Next Steps

•To start scanning, see Chapter 3, “Scanning.”

•For detailed information on scanning and manipulating images, see Chapter 5, “Scanning Techniques.”

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.

CONTENTS

GLOSSARY

INDEX

Chapter 3	14
Scanning
Scanning

You can choose to scan the image without changing the default scan settings, or you can use ScanGear CS-S’s settings to preview and adjust a variety of settings prior to scanning. ScanGear CS-S’s settings are also dependent on your scanner’s capabilities and the capabilities of the imaging application you are using.

Acquiring an Image

When an application receives a scanned image directly from a scan, it is acquiring the image. Throughout this manual, you will see references to “acquiring an image.” This means that an application is using ScanGear CS-S to import the image from the scanner; so it is acquiring the image from the scanner via ScanGear CS-S.

Features of the ScanGear CS-S Window

The main ScanGear CS-S window is used to preview, adjust, and scan images when the acquiring software lets you preview the image before scanning. For details on applications that do not open the ScanGear CS-S window, see “Scanning in “Windowless” (UI-less) Mode.”

The Preview Area

The preview area lets you “prescan” an image before it is scanned and acquired by the application. The preview shows how the scanned image will look after you scan.

When an image is previewed, you can use the tools on the toolbar to select a portion of the image to scan, rotate or resize the image, or view the image’s appearance after you make changes to the scanning mode, tone, or other settings. The horizontal and vertical rulers, selectable on the toolbar, let you see the dimensions of the image.

Clear, Preview and Scan Buttons

The Clear, Preview and Scan buttons control the scanner. When you click Clear, the image displayed in the preview area is cleared. When you click Preview, the image on the scanner is scanned into the preview area but not yet saved in the acquiring application. When you click Scan, the image displayed in the preview area is scanned and sent to the acquiring application. For details, see “Previewing an Image,” later in this chapter.

Toolbar

The toolbar has a set of tools that let you change the previewed image’s shape and size. You can rotate the image, select a part of the image, zoom in and out, create a negative image, flip an image, and turn rulers on and off. For full details on these tools and their functions, see “Changing the Preview Image Shape and Size,” later in this chapter.

Status and Message Areas

The status area at the bottom of the ScanGear CS-S window summarizes the color mode, resolution, width and height, and the estimated file size of the currently previewed image when it is acquired by the application. For more information on estimating file sizes, see Chapter 5, “Scanning Techniques.”

The message area on the lower left of the window displays messages related to the preview area and toolbar.

Settings Tabs

Each tab (Main, Tone, Preferences, and the device tab) contains settings that let you modify the acquired image.

For information about the settings on the Main tab, see “Setting Scan Mode, Resolution, and Dimensions.” For information about the settings on the Tone tab, see “Setting Image Tones.” For information about the Preferences tab settings, see “Setting General Preferences.” For information about the FB1200S tab, see Chapter 4, “Scanning Devices.”

Quick Start to Scanning

Use these steps to get going with ScanGear CS-S quickly, with the installed settings.

Note: ScanGear CS-S does not launch unless the scanner’s AC adapter is plugged in and recognized by Windows.

Preparing the Scanner

Before you start scanning, be sure the scanner is properly connected and the AC adapter is plugged in before you turn on your PC. If you want to ensure that the scanner is functioning correctly, run the Test Scanner from FB1200S tab. See “Testing the Scanner” in Chapter 4, “Scanning Devices.”

Place the item to be scanned image side down, and position it squarely on the platen.

Previewing an Image

The advantage of using ScanGear CS-S is that you can preview the image and make changes before actually scanning. That way, you can make sure you are getting the most out of your scanner’s capabilities and of your time spent scanning and working with the image.

Some applications, (for example OCR applications) do not require the ScanGear CS-S window to open before the scan starts. However, ScanGear CS-S has settings such as Text Enhanced that automatically give you the best available scan without previewing the image.

To preview an image:

1.Place the item to be scanned on the scanner.

2.You must select a source if you have not already done so. On the menu of your imaging application, use the command that selects the data source. On many imaging applications, the menu item looks similar to the following picture:

In the Imaging application that is included in the Windows 95/98 Accessories, the command is “Select Scanner” on the File menu.

CONTENTS Chapter 3 17

		A Select Source or Select Scanner dialog box appears that looks similar to
		the following picture:

3.Select the source of the scan, and click Select (or OK).

Now you are ready to acquire the image.

4.On the menu of your imaging application, select the command that begins the scanning process. On some applications, this is “Acquire/Image;” in the Imaging application included in Windows 95/98, it is “Scan New.”

Unless you are using ScanGear CS-S in “windowless” mode, the ScanGear CS-S window appears.

Previewing starts automatically (Auto Preview is switched on at default settings).

The ScanGear CS-S main window opens, scanning begins automatically, and preview begins. When preview is finished, the preview image is displayed in the Preview Area.

When Auto Preview is switched off in the basic settings, click the Preview button to start image preview.

5.To change a default setting before you preview, click the appropriate ScanGear CS-S settings tab and select the settings you need. For full information on each setting, see “Specifying How the Image is Previewed,” later in this chapter.

6.On the Main tab, make sure you set the scan mode and resolution. If you want to change the mode after you preview - for example, to change from Color to Grayscale - the preview image clears, the preview area reverts to its default size, and you must preview the image again.

Note:	If necessary, you can cancel a preview or scan. During a
	preview, the Preview button becomes a Cancel button. During
	a scan, you can click Cancel on the progress dialog box.
	Calibration will automatically be performed before scanning.

7.To adjust the image in the preview area, do one or more of the following:

•The Crop tool is selected automatically when you launch ScanGear CS- S. If there is white space around your preview image, crop the image to eliminate the white space and any other unwanted part of the image. If you do not crop the image, the white space is included in the final scan. For details, see “Cropping Part of an Image” later in this chapter.

•To view the image dimensions in the preview area, click the Rulers button to display the horizontal and vertical rulers.

•Use the Zoom tool to zoom in before you crop. See “Zooming In and Out,” later in this chapter. You can also use the Width and Height text boxes on the Main tab in conjunction with the Crop tool to make your selection more precise. If you want the acquired image to be larger or smaller than the current preview size, use the Scale setting to set a different percentage. For more information about zooming and scan resolution, see Chapter 5, “Scanning Techniques.”

•Adjust the Contrast/Brightness, Gamma, or other tone settings to adjust the image tone. When you adjust tone settings, you see the results immediately in the preview image. For more information, see the section “Setting Image Tone” later in this chapter.

Where is the Scanned Image?

Once scanned, an image becomes one of the acquiring application’s open files. When ScanGear CS-S is launched from a TWAIN-compliant program, clicking the Scan button also saved the image in the format determined by the application from which ScanGear CS-S was launched.

Scanning in “Windowless” (UI-less) Mode

Some applications use ScanGear CS-S without opening the ScanGear CS-S window (the user interface, or UI). These applications include Pagis, Microsoft MS Picture It!, and most OCR (Optical Character Recognition) software. If you are using software that does not open the ScanGear CS-S window, you are unable to use any of the features on the ScanGear CS-S window. However, with some applications, you may be able to perform a “custom” scan that will open the ScanGear CS-S window.

For applications that do not show the ScanGear CS-S window, ScanGear CS-S automatically uses the settings determined by the application that will perform the scan with optimal results. Follow the instructions in your application to scan the images.

Cropping Part of an Image

Click Crop and drag diagonally across an area of the image in the Preview window to select that area. The area you select is outlined with a broken line.

You can adjust the crop lines once you have selected an area. If you hold the cursor over the selection handle in the middle of a crop line, a two-headed arrow appears. You can drag the line in or out to adjust the width and height of the image.

Click outside the broken line to crop a different area.

•If you crop too small an area, the size resets.

•If you type new values in the Width and Height text boxes, the selected preview area changes. If the Keep Proportions button is turned on when you select a new area (you see a chain between the Width and Height boxes), the proportions match the last locked proportion.

•The minimum scan width and height varies depending upon the scan resolution selected. For example, at 75 dpi, the minimum width and height is 9 pixels for a preview scan. At 300 dpi, the minimum width and height is 35 pixels for a preview scan.

Note: If your mouse has left-handed settings, the right and left mouse settings for ScanGear CS-S tools are reversed.

Moving an Image

The Move Image tool lets you move a zoomed image in the preview area. Click Move Image and drag the zoomed image around to display hidden parts of the zoomed image.

Zooming In and Out

Click Zoom to enlarge the image in the preview area. Click once to enlarge the zoomed image 2x. The maximum enlargement is 16x. Right-click the image once to zoom out and reduce the enlarged image 2x per mouse click.

Creating a Negative Image

Use the Negative/Positive tool to create a negative image of the original. A negative image is created by converting the colors in the image to their complementary colors - the opposite color on the color wheel. Clicking a second time makes a negative image of the negative image, thus returning the image to the original positive image.

Specifying How the Image is Previewed

Before you scan or preview, you can change the mode and specify how the image appears in the acquiring application.

To specify how the image is previewed:

1.Choose the Scan Mode that best matches how you want the scan of the object to be output.

Note: If you have already scanned an image and then change the scan mode, the image is cleared from the preview area, and you lose your preview image and all the settings you have made.

Setting Scan Mode, Resolution, and Dimensions

When ScanGear CS-S is installed, the settings are in place and you can scan without changing them. However, there are a wide variety of options available for you to change the look of the preview and scanned image. You can change the settings at any time and preview the results. Repeat this process until you are ready to complete the scan. Some changes (Tone tab settings and output size) take effect immediately and can be seen on the preview image; some changes (changing the scan mode) require that you click the Preview button again.

The primary settings for image acquisition, including scanning mode, resolution and scanning area, are on the Main tab.

Setting Scanning Mode

The scanning mode-Black and White-affects the settings on all the other tabs. The icon to the left of the list box reflects the current selection.

Indicates current mode:

Black and White

Grayscale (8 bit)

Grayscale (12 bit)

Color (24 bit)

Color (36 bit)

Text Enhanced

Note: If an image is in the preview area when you change the scan mode, the image disappears and the preview area resets to the default size.

To set scanning mode:

1.Click the Main tab.

2.Select an option from the Scan Mode list. You have the following choices:

•Color (36 bit): 36 bit color images contain 12 bits per pixel for each primary color (red, green, blue). Use this option to attain a scanned color image of the highest quality. However, the file will be approximately twice the size of a Color (24 bit) file.

•Color (24 bit): 24 bit color images contain 8 bits per pixel for each primary color. Use this option to attain a scanned color image of average quality.

•Grayscale (12 bit): 12 bit grayscale images contain 12 bits per pixel.

Use this option to attain a scanned grayscale image of the highest quality. However, the file will be approximately twice the size of a Grayscale (8 bit) file.

•Grayscale (8 bit): 8 bit grayscale images contain 8 bits per pixel. Use this option to attain a grayscale image of average quality.

•Black and White: Images are expressed in two colors only; black or white. A pixel is set to black or white depending on its brightness value in relation to a particular threshold value. The threshold value can be freely set. Select this option to print photographs on monochrome printers.

•Text Enhanced: Text Enhanced images are Grayscale images (8 bits per pixel) converted to Black and White (1 bit per pixel) using Canon ImageTrust technology. You can select Text Enhanced in the Scan Mode list. If the application operates in windowless (UI-less) mode, you can select “Text Enhanced” in the Preferences tab, and request the application to perform a Black and White scan. In this case, the conversion to Black and White takes place automatically.

The acquiring application may determine your Scan Mode choice. For example, if a fax application is acquiring the image, you may not be able to choose a color mode; you may have to choose Black and White or Grayscale.

The 24 bit and 36 bit options express colors with conversions of each primary RGB color (Red, Green, Blue). The 24 bit options can express each color with up to 256 gradations, and 36 bit color with up to 4,096 gradations. If you need extremely high-quality color gradation in the scanned image, use 36 bit color. Otherwise, use 24 bit for normal color scanning jobs.

The Grayscale options express varying shades of gray between white and black. The Grayscale (8 bit) option can express shades within a range of 256 gradations and the Grayscale (12 bit) option within a range of 4,096 gradations.

Note:	If you attempt to use the Color (36 bit) or Grayscale (12 bit)
	options to scan an image with a software application that
	does not support these options, the system may hang up.
	Before you use either 36 bit or 12 bit grayscale, check the
	specifications of the parent software application to confirm
	whether these options can be used. You can use Color (36 bit)
	and Grayscale (12 bit) with Photoshop Ver. 4.0 or later and
	with Photoshop LE enclosed with this package.

If you scan an image with a version of Photoshop compatible with 36 bit color and 12 bit grayscale, the image is scanned as a 16 bit Channel Mode image.

Selecting Scan Resolution

Using the Scan Resolution list, you can select the resolution of a scanned image based on the selected output device. This resolution becomes the base on which changes to image size and scale are calculated.

The resolution you choose depends on the limits of the printer or other output device. However, you can also select a custom resolution and make more specific resolution choices.

Note: The maximum resolution of the scanner is set at 600 dpi when the optional automatic document feeder (ADF) is installed.

Selecting a Preset Resolution

The list of preset resolutions should cover most of your scanning needs. Available resolution settings depend on the capabilities of the acquiring application.

To select a preset scan resolution:

Select an option from the Scan Resolution list.

Depending on your selected device, you have different resolution choices. For example, if the acquiring application is configured to print the image, your choices may be limited to the printer’s maximum resolution.

Setting Units of Measurement

In the Units list, you specify the unit of measure for width and height of the scanned image. The preset unit of measurement is based on the Measurement System setting of the Regional Settings in your Windows Control Panel.

To set units of measurement, select inches, centimeters, or pixels in the Units list. The Width and Height values display in the units you choose.

There is no change to the size of the selection rectangle in the preview area when units of measurement are changed, but the horizontal and vertical rulers reflect the currently selected measurement units. For example if you select centimeters, the default Width value of 8.49 inches changes to 21.57 centimeters.

Setting Image Width and Height

The Width and Height text boxes contain the width and height of the current selection or, if there is no selection, the maximum output size, measured from the upper left of the image in the preview area and based on the currently selected paper size.

The width and height values change when you select part of the image in the preview area. Correspondingly, when you change the amounts in the Width and Height boxes, the selection borders in the preview area change to match.

To change size without constraint, do one of the following:

•Click the Crop button on the toolbar and select a section of the image in the preview area. The measurements in the Width and Height text boxes display the new sizes.

•Type the desired measurements in the Width and Height text boxes. The image selection borders change to match the width and height you enter.

Maintaining Image Proportion

The Keep Proportions button affects the selection, Width and Height values, and the scale.
