Editing the Source Code (Part 2)

In the source file <Project name>Dlg.cpp:

1. Add the following lines after the #include section at the top of the file:

   Copy

   #include <vision/PMRedLine/PMRedLineTool.hpp>
   
   using namespace Cognex;

2. Add the following to the OnBnClickedRunTool method:

   Copy

   // Always use Object::Create<class>() instead of std::make_shared<class>()
   //
   // Static train rectangle, to persist between tool runs.
   static Vision::RectanglePtr trainRect{};
   if (!trainRect)
   {
       trainRect = Vision::Object::Create<Vision::Rectangle>();
       trainRect->setInteractive(true);
       trainRect->setGraphicDOFEnable(Vision::RectangleDOFConstants::All);
       trainRect->SetXYWidthHeight(40, 85, 100, 100);
       trainRect->setSelectedSpaceName("#");
       trainRect->setTipText("Train Region");
   }
   
   // Static train origin coordinate axes, to persist between tool runs.
   static Vision::CoordinateAxesPtr trainAxes{};
   if (!trainAxes)
   {
       trainAxes = Vision::Object::Create<Vision::CoordinateAxes>();
       trainAxes->setInteractive(true);
       trainAxes->setGraphicDOFEnable(Vision::CoordinateAxesDOFConstants::All);
       trainAxes->setSelectedSpaceName("#");
       trainAxes->setTipText("Train Origin");
   
       trainAxes->Transform() = Vision::Object::Create<Vision::Transform2DLinear>();
       trainAxes->Transform()->setTranslationX(85);
       trainAxes->Transform()->setTranslationY(135);
   }
   
   // Static top graphics record, to persist between tool runs.
   static auto topRecord = Vision::Object::Create<Vision::Implementation::Record>();
   
   // Load image -- used for both input and training.
   auto imageFileTool = Vision::Object::Create<Vision::ImageFile::ImageFileTool>();
   imageFileTool->Operator()->Open("images\\coins.idb", Vision::ImageFile::ImageFileModeConstants::Read;
   imageFileTool->Run();
   auto image = imageFileTool->OutputImage();
   
   // Create PMRedLine tool.
   auto redLineTool = Vision::Object::Create<Vision::PMRedLine::PMRedLineTool>();
   
   redLineTool->SuspendChangedEvent();
   
   // Set input image.
   redLineTool->setInputImage(image);
   // Configure training pattern.
   redLineTool->Pattern()->setTrainImage(image);
   redLineTool->Pattern()->setTrainRegion(trainRect);
   redLineTool->Pattern()->setOrigin(trainAxes->Transform());
   // Configure run parameters.
   redLineTool->RunParams()->setNumberToFind(6);
   redLineTool->RunParams()->ZoneScale()->setConfiguration(
       Vision::PMRedLine::PMRedLineZoneConstants::LowHigh);
   redLineTool->RunParams()->ZoneScale()->setHigh(1.1);
   redLineTool->RunParams()->ZoneScale()->setLow(0.9);
   // Configure last-run record.
   auto lastRunRecordEnable = (int)Vision::PMRedLine::PMRedLineLastRunRecordConstants::All;
   lastRunRecordEnable &= ~(int)Vision::PMRedLine::PMRedLineLastRunRecordConstants::ResultsCoordinateAxes;
   redLineTool->setLastRunRecordEnable(
       (Vision::PMRedLine::PMRedLineLastRunRecordConstants)lastRunRecordEnable);
   
   // Train and run PMRedLine tool.
   redLineTool->Pattern()->Train();
   redLineTool->Run();
   
   redLineTool->ResumeAndRaiseChangedEvent();
   
   topRecord->SubRecords()->Clear();
   topRecord->SubRecords()->Add(redLineTool->CreateCurrentRecord());
   topRecord->SubRecords()->Add(redLineTool->CreateLastRunRecord());
   
   m_display.setAutoFitWithGraphics(true);
   m_display.setSubject(topRecord);

3. Add the following line to the OnSize method:

   Copy

   m_display.OnSize(nType, cx, cy);
