Applications
Description
The operation reads a DataMatrix code on the inImage.
The operation is capable of reading codes from images subject to perspective distortion.
Supported code types: ECC 200 and ECC 000-140.
Around datamatrix must be quiet zone. The minimum quiet zone is equal to the width of a module on all four sides. For applications with moderate to excessive reflected noise in close proximity to the symbol, a quiet zone of 2 to 4 module widths is recommended.
