Enhanced Bar Code Engine

VRS User’s Manual

The application searches for bar codes in a linear fashion, examining the search area 

for potential bar codes. For horizontal bar codes with an orientation of 0, for example, 

it works down the image starting on the left and searching toward the right edge; for 

vertical bar codes, it works across the image starting on the top edge and searches top 

to bottom. Bar codes can be oriented on an image in four general directions. You can 

select the 0, 90, 180, or 270 check box for the direction you would like to search. 

The bar code Quality refers to the condition of bar code elements on an image. For 

example, sometimes the bar code elements are well defined; the black bars are clearly 

delineated, and very little noise exists on the image. In some cases, the black bars are 

too light, or noise exists in the bar code’s quiet zone. Because these factors can affect 

the application’s ability to accurately read the bar code, you can specify the quality of 

the bar codes being read.

• Good—Well delineated, have smooth edges, and are noise free.
• Normal—Generally well delineated, but may have some noise and rough 

edges.

• Poor—Have jagged edges or other characteristics that might make them hard 

to read.
