Datacode

Configure Datacode settings such as No Read String, Module Size, or Search Strategy. This tool is helpful for reading 2D barcodes that are difficult to decode and 1D codes with selected symbology.

General Datacode Decode Settings

General Datacode decode settings include defining timeouts, symbologies, no-read string, module size, contrast threshold, polarity, and string match.

General Datacode Decode Settings
Setting	Description
Timeout	Set a time limit to stop the execution of the inspection tool, resulting in a failure.
No Read String	Determine the string that is shown when there are no decoded values.
Module Size	The minimum and maximum module sizes.
Contrast Threshold	The threshold used for Datacode.By default, this is set to 10.
Polarity	Select a polarity for the decode: Any Bright Dark
Barcode String Match	Define a string that must be exact or contained within the barcode or datacode output for the tool to pass: Disabled - no match string. Exact String - string must match the exact string provided. String Contains - code must contain the match string. RegEx - enable to input complex match string conditions.

Advanced Datacode Decode Settings

Advanced Datacode decode settings include four sections: Detection, Matrix Codes, DPM, and Linear Codes. Detection settings include defining a detection strategy, a decoding strategy, a detection method, a finder tradeoff, allowing distortion, a perspective level, a code slant, background suppression, and codes with broken edges. Matrix Codes settings include defining code sizes (row and column count), mirrored codes, rectangular codes, and codes with broken corners. DPM settings include defining a mixed polarity, grid-based detection. Linear Codes settings include defining a length, high confidence, high blur, damage, no quiet zone, and addons.

Advanced Datacode Decode Settings
Setting	Description
Detection Strategy	Specify the step of image downsampling used for finding codes at different scales: Super Fast Fast Precise Strict Extended
Decoding Strategy	Specify the precision of outline detection: Super Fast Fast Precise Strict Extended
Detection Method	Specify how code candidates are located: Finder Pattern Finder Edges
Finder Tradeoff	Decide how to optimize parameters for weak or jagged edges: Extra Sensitive Sensitive Balanced Robust Extra Robust
Allow Distortion	Specify a distortion level: None Low Medium High Auto (slower)
Perspective Level	Specify a perspective distortion of the code grid: None Low High
Maximum Code Slant	Specify the maximum deviation from the right angle in the corner of the Finder Pattern.
Expected Gap Size	Specify the distance between neighboring modules. Zero Small Medium Large
Maximum Code Slant	Specify the maximum deviation from the right angle in the corner of the Finder Pattern.
Allow Broken Edges	Employs an extended edge tracker that is able to skip missing pixels. Applies primarily to the FinderEdges method.
Background Suppression	Turns on an additional preprocessing step that removes low-contrast background areas.
Code Sizes	Limit the number of Data Matrix modules in a row and column.
Allow Mirrored	Allows codes to be mirrored/transposed.
Allow Rectangular	Allows codes to be rectangular
Allow Broken Corner	Tries to create a candidate even if the bottom-left corner of a Data Matrix code is occluded.
Enable DPM	Enables an algorithm for direct part marking.
Allow Mixed Polarity	Enables reading modules with both bright and dark pixels simultaneously.
Grid-based Detection	Enables reading codes with highly damaged Fixed Pattern (slow)
Dot Size	Optimizes the algorithm parameters for small, medium, or large dots, or for fully-printed (normal) codes. Applies to DotGrid and FinderPattern methods. Available options: Small Medium Large Full Auto
Length	Barcode Length: Any Discrete - select a specific number as the barcode length. Range - select a range of numbers as the barcode length.
Extra High Confidence	Enables filtering out detected codes with low score.
Allow High Blur	Enables high-blur digitizer.
Allow Damage	Enables reading of barcodes with dirt, holes or occlusions.
Allow No Quiet Zone	Enables reading codes without the obligatory empty areas before and after the bars.
Allow Add ons	Enables EAN and UPC add-ons 2 and 5
