Description
Decode Strategy
Changes the variables to alter the balance of speed and performance.
  • Fast – This strategy is designed to be fast but may not find a barcode if it is hard to find.
  • Moderate - This strategy is helpful for most use cases with a moderate increase in analysis times.
  • Exhaustive – This strategy does an exhaustive search to find hard to find barcodes. This method can sometimes lengthen analysis time significantly.
Detection Method
Determine the preferred method for detecting the data:
  • Uniform - uses a splatter pattern to uniformly analyze the whole image. This is helpful for 1D and 2D barcodes that have a lot of noise. If you are looking for a random pattern, slightly favor the center of the image.
  • Quiet Zone - specialized to find 2D barcodes fast and helpful when over 8 pixels of buffer zone around the barcode is expected. This setting may not be helpful for use cases when the buffer area is less than 4 pixels or 1D barcodes.
  • Finder Pattern - uses a contrast map that finds patterns with little or no noise. This method is applicable to 1D and 2D barcodes.
Allow Rectangular Codes
Allows the reading of 2D rectangular barcodes in addition to square 2D barcodes.
Expected Module Size (Pixels)
Define the range (pixels) you expect a module to be in given barcodes to help increase read performance.
A module is the smallest divisible unit of a barcode; for 1D, typically the width of a single thin line; for 2D, the pixel size. This setting serves as a general guidance to increase performance, but is not a strict threshold.
