Chapter 8 ISIS/TWAIN Driver Settings
Area Window
The size indicated for the Area panel corresponds to the
page size setting, and the area within the panel indicates
the current scanning area.
Hint
• The scanning area can be adjusted by dragging the handles
(
■
) bordering the Area panel with your mouse.
• With CapturePerfect, the last scanned image appears in the
Area panel.
Margin
This control adjusts the top, bottom, left, and right margins
around the scanning area so that you can expand the
scanning area to include the edges of a document, or
reduce it to avoid black frames around scanned images
when you set the [Background Color] to [Black].
Hint
• If the edges of documents are missing from scanned images,
move the slider to the right to expand the scanning area.
• To eliminate the black frame around scanned images, reduce
the scanning area by moving the slider to the left.
• The measurement units for margins are determined by the
[Unit] setting. However, changing the margin [Unit] setting is
not possible on the advanced version of the [Basic] tab sheet
.
[Preview] Button (TWAIN driver only)
Load the document and then click the [Preview] button to
scan one document page and display its preview image in
the Area panel.
[Brightness] Tab Sheet
On the [Brightness] tab sheet you can adjust brightness and
contrast for scanning, and access gamma settings. The
availability of brightness and contrast settings depends on the
mode setting of the [Basic] tab sheet.
