The document capture region is a rectangular piece of paper, or a portion of it enclosed by a rectangular border.
In either case, all four sides of the capture region must be completely within the scanner's field-of-view, and there must be sufficient contrast at the border of the capture region. For example, if a piece of white paper contains the document to capture, it must be put in front of a dark background.
By default, the scanner captures the largest rectangular region within the field-of-view. To specify a particular border type, use the IDC Border Type parameter.
The region must contain at least 10% of the field-of-view in two dimensions.
If an IDC barcode is decoded, IDC uses its location to start the search for the capture region. Otherwise, it searches the capture region from the center of the field-of-view. IDC also uses the orientation of a decoded IDC barcode to orient the output image.
