Image outputs
i100 Series Scanners can return bi-tonal, grayscale or color images to
the host. Below is a description of the valid combinations.
The i150 Scanner is a simplex scanner. This means that only one side of
the document may be captured.
The i160 Scanner is a duplex scanner. This means both the front and
the rear side of each document may be captured. For each side
captured, the scanner can be configured to return either one or two
images per side:
• Single output (one image per side): bi-tonal/binary, grayscale, or
color.
• Simultaneous output (two images per side): bi-tonal and color or
bi-tonal and grayscale.
The host application controls which of these images is transferred to the
host to be stored as an image file. An example of simultaneous output
where all four images are returned to the host would create the following
four files:
• Front bi-tonal/binary: FB.tif. This image file represents the
contents of the front side of the document using one-bit per pixel.
• Front color: FC.jpg. This image file represents the contents of the
front side of the document using 24-bits per pixel.
• Rear bi-tonal/binary: RB.tif. This image file represents the contents
of the rear side of the document using one-bit per pixel.
• Rear color: RC.jpg. This image file represents the contents of the
rear side of the document using 24-bits per pixel.
NOTE: Actual file formats are determined by the host application.
