the pixel raster scan line. Decoding is performed in the “normal” direction (left bars more significant
than right bars for horizontal symbols; top bars more significant than bottom bars for vertical symbols).
7 = enable PharmaCode decoding, Color bars expected; relaxed contrast rules for the three least
significant bars. Vertically oriented symbols are decoded. Note that vertically oriented means that the
bars are parallel to the orientation of the pixel raster scan line. Decoding is performed in the “normal”
direction (left bars more significant than right bars for horizontal symbols; top bars more significant than
bottom bars for vertical symbols).
9 = enable PharmaCode decoding, no color bars expected; standard rules for all bars. Horizontally
oriented symbols are decoded. Note that horizontally oriented means that the bars are perpendicular to
the orientation of the pixel raster scan line. Decoding is performed in the “reverse” direction (right bars
more significant than left bars for horizontal symbols; bottom bars more significant than top bars for
vertical symbols).
11 = enable PharmaCode decoding, Color bars expected; relaxed contrast rules for the three least
significant bars. Horizontally oriented symbols are decoded. Note that horizontally oriented means that
the bars are perpendicular to the orientation of the pixel raster scan line. Decoding is performed in the
“reverse” direction (right bars more significant than left bars for horizontal symbols; bottom bars more
significant than top bars for vertical symbols).
13 = enable PharmaCode decoding, no color bars expected; standard rules for all bars. Vertically
oriented symbols are decoded. Note that vertically oriented means that the bars are parallel to the
orientation of the pixel raster scan line. Decoding is performed in the “reverse” direction (right bars
more significant than left bars for horizontal symbols; bottom bars more significant than top bars for
vertical symbols).
15 = enable PharmaCode decoding, Color bars expected; relaxed contrast rules for the three least
significant bars. Vertically oriented symbols are decoded. Note that vertically oriented means that the
bars are parallel to the orientation of the pixel raster scan line. Decoding is performed in the “reverse”
direction (right bars more significant than left bars for horizontal symbols; bottom bars more significant
than top bars for vertical symbols).
12 OCR Template
12.1 OCR Introduction
OCR is designed to encompass both human readable and machine readable information in the same
symbol or text. Conversely, bar codes were designed to greatly assist the ability of machines to read
information at the expense of human readability. In OCR, there is little redundant information in a
character; most of an OCR character must be present to allow recognition. There are subtle differences
between some OCR characters that are easy for a human to distinguish, but present challenges to
machine vision systems in the presence of lower sample density, noisy images, and/or degraded
symbols.
While much effort has been spent to provide a superior OCR capability, users should be cautioned that
OCR decoders are more susceptible to misreads and noreads than their bar code counterparts.
Consequently, The OCR decoder reads OCR only when it is provided with templates detailing the
