Datacode

Datacode

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

General Datacode Decode Settings

General Datacode decode settings include defining a timeout string, no read string, 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
Specify a no read string.
Polarity
Select a polarity for the decode.
  • Any
  • Bright
  • Dark
  • Mixed
String Match
Enable String Match to decode successfully when the value matches the string provided.

Advanced Datacode Decode Settings

Advanced Datacode decode settings include defining a detection strategy, decoding strategy, module size, detection method,  finder tradeoff, contrast threshold, line count, distortion, gap size, code slant, super resolution, perspective level, edge tracker, mirrored codes, broken patterns, rectangular codes and codes with broken corners.
