Unit; Preview Window - Canon CanoScan D646U User Manual

Unit

Specifies the units that define the size of the scanned image.
Unit Settings Dialog

Preview Window

You can size the preview window and set its resolution. Enter a large value for a
large preview window size. You can also use this feature to set the auto preview
and preview cache options.
Preview Window Settings Dialog
During previewing, if you are running other tasks simultaneously
which may burden the computer extremely (i.e.: playing animation
and starting and editing a file with a size of more than 100MB),
uncheck this check box to set this setting off. The initial setting is
"Checked (On)".
Caution
• Changing the preview window size will cause the image previously
displayed in the preview window to disappear.
Hint
• If the "Save preview image" option is selected, the last preview image will
appear in the preview window when Plug-in Module CS-U is launched
again after quitting once. This reduces the steps required to rescan the
same image repeatedly.
The units displayed in this section of the control panel will change.
