13 - 18 DS8178 Digital Scanner Product Reference Guide
Free-Form Mode Demo
Set IDC Operating Mode to Free-Form.
•
Pull the trigger. The decoder decodes the bar code and captures an image of the entire rectangle, including
the contents.
•
Modify the values for height, width, x, and y. Pull the trigger. Note that the captured image is not affected.
•
Rotate the form clockwise so the word Capture is along the bottom edge, and pull the trigger. The decoder
decodes the bar code and captures the same image, including orientation. (This example also works with the
form rotated counterclockwise or upside down).
•
Cover the bar code with a small piece of paper and pull the trigger. The decoder does not decode the bar
code and does not re-orient the captured image to the normal position, i.e., with the logo in upper-left corner.
What this demonstrates:
The Intelligent Document Capture Free-Form mode captures an image whose size and position are
determined by a rectangular border on the page. It adjusts the image to the upright orientation if a bar code is
found and decoded in the image.
Linked Mode Demo
Set IDC Operating Mode to Linked.
The examples from Free-Form mode also work in Linked mode except that the last one (with the bar code covered)
does not decode the bar code or capture an image.
What this demonstrates:
The Intelligent Document Capture Linked mode captures an image whose size and position are determined by
a rectangular border on the page. The IDC firmware requires that a bar code is present in order to capture an
image, decodes it, and uses it to adjust the image to the upright orientation
Other Suggestions
Hold the decoder at an angle (up/down or side to side) to the page instead of perpendicular to it. The IDC firmware
de-skews and adjusts the brightness (enabled by default) to produce a quality image when the decoder is held at
less than ideal conditions.
