Reading a Grid of Matrix Codes¶

This code snippet shows how to read matrixcodes that are disposed in a 5 by 3 grid with 10% overlap between grid cells.

C++¶

#include <eVision/EasyMatrixCode/EasyMatrixCode2/EMatrixCodeReader.h>

using namespace eVision;
namespace EMC2 = eVision::EasyMatrixCode2;

EImageBW8 srcImage;
ERectangleRegion gridRegion;
EMC2::EMatrixCodeReader reader;

// Reading succeeds
EMC2::EMatrixCodeGrid grid = reader.Read(srcImage, gridRegion, 3, 5, 0.1f);

std::vector<EMC2::EMatrixCode> codesMiddleCell = grid.GetResults(1, 2);

C#¶

using eVision;
using EMC2 = eVision.EasyMatrixCode2;

EImageBW8 srcImage = new EImageBW8();
ERectangleRegion gridRegion = new ERectangleRegion();
EMC2.EMatrixCodeReader reader = new EMC2.EMatrixCodeReader();

// Reading succeeds
EMC2.EMatrixCodeGrid grid = reader.Read(srcImage, gridRegion, 3, 5, 0.1f);

EMC2.EMatrixCode[] codesMiddleCell = grid.GetResults(1, 2);

Python¶

import eVision
from eVision import EasyMatrixCode2 as EMC2
src_image = eVision.EImageBW8()
gridRegion = eVision.ERectangleRegion()
reader = EMC2.EMatrixCodeReader()

# Reading succeeds
grid = reader.Read(src_image, gridRegion, 3, 5, 0.1)

codesMiddleCell = grid.GetResults(1, 2)
