What is Decode?
The first step in analysing the profile, after identifying the bar and space regions in the profile and determining the position of each element edge, is to apply the reference decode algorithm – the set of rules/steps for decoding a symbol defined in the symbology specification – to the elements “seen” in the scan reflectance profile. If a valid decode results, the decode parameter passes and is given grade 4, otherwise it fails (grade 0). If the wrong number of elements is seen, the decode clearly fails. Note that in the ANSI standards this last case is graded separately as an “edge determination” failure, although the final effect on the profile grade is the same.
