Setting	Description
Decode Strategy	Changes the variables to alter the balance of speed and performance. Fast – prioritize speed over decode performance Moderate - balanced Exhaustive – prioritize decode performance over speed
Detection Method	Determine the preferred method for detecting the data: Quiet Zone - helpful when over 8 pixels of buffer zone around the barcode is expected. This setting is unsuitable for use cases when the buffer area is less than 4 pixels. Uniform - uses a splatter pattern to uniformly analyze the whole image. This is helpful for images that have a lot of noise. If you are looking for a more random pattern, slightly favor the center of the image. Finder Pattern - uses a contrast map that helps find patterns with little or no noise.
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 is used as general guidance to increase performance but is not a strict threshold.
