Compression
When built-in compression hardware is present, this control allows you to select
the type of compression that will be recorded in the image’s Settings file, for use
when scanning directly to a file. Note that images scanned to a displayed window
will not be compressed.
Line Art Filtering
All of the line art filtering options work only with 1 bit/pixel images (line art,
black and white images).
• None
No filtering will be done.
• Bold Lining
This removes single black dots, extracts edges, thickens edges.
• Edge Detection
This looks for the boundaries between black and white and connects them to
form outlines of the objects in the image.
Smoothing
Smoothing softens the transition between black and white by creating the illusion
of gray.
Speckle Removal
Speckle removal eliminates extraneous dots in the image.
Image Filtering
• None
This will disable filtering of images.
• Averaging
Choosing this option averages 2x2 neighborhoods of pixels together to
achieve a “smoothing” effect.
• MTF
