Scanning
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.
