C. Smoked Glass as Background
This option lets you apply a smoked glass
background that makes your scan jobs stand out
more clearly. This feature can also be used if
you have multiple scan jobs in their respective
image modes, and this will be shown clearly in
the Preview window (example: 1 job in color,
another in B&W).
D. Scan Quality
This option allows you to select the image
quality by controlling the scanner hardware and
the maximum image processing depth.
• Speed: Choose this option if your primary
concern during scanning is speed. Image
data is delivered faster and the image data
is processed in 8 bits per channel.
• Quality: This is the default setting. Scanned
data is delivered a little slower but in high
quality, and the image data is processed in 8
bits per channel.
• Best: This setting is available only to
higher-depth scanners (10-, 12-bit, or
higher). Scanned data is delivered a little
slower but in high quality, and image data is
processed in maximum bits per channel
(i.e., 10-, 12-bit, or higher), and then
converted to the desired output depth. This
special operation results in the best image
quality possible.
E. Memory Usage
This option controls the way ScanWizard 5 uses
memory. Three options are provided:
• Application: ScanWizard 5 will only use
the memory inside the application heap as
its image buffer. Make sure you allocate a
large number of memory in your applica-
tion for this purpose. Otherwise,
ScanWizard 5 may not have enough
memory to run. Use this option only if you
don't want ScanWizard 5 to use memory
outside your application.
• System: ScanWizard 5 will use the memory
in the system heap as its image buffer, and
only a limited amount of memory is used in
the application heap. This option is best if
you have only a small memory allocation
for your application but a large amount of
system memory.
• Auto: This is the default setting.
ScanWizard 5 maximizes the memory
usage from both system and application,
looking for memory first from the system
heap and then from the application heap.
G. Scratch Directory
The scratch directory is the folder where
ScanWizard 5 creates temporary files, with the
Smoked glass background turned on shows
multiple scan jobs in their respecitve image
modes (color or grayscale)
