EasyGaugeRegion

Support
Required licenses	EasyGauge, EasyObject
Recommended images	Any image from the folder Sample Images/EasyGauge
Location	Matching and Measurement/EasyGaugeRegion

Purpose

This sample program demonstrates how to:

• Load an image and apply a gauge from , chosen between a Rectangle Gauge and a Circle Gauge.

• Create a region corresponding to the gauge from the result.

• Perform a blob encoding operation on it.

The color of each blob is assigned depending on its center position; thus, the colors change when you move the gauge

Code highlights

1. Perform the measurement with ECircleGauge.

   // Measure a circle
   ECircleGauge m_CircleGauge;
   m_CircleGauge.Measure(&m_Image);
   

2. Build an ERegion from the resulting circle.

   // Use measured circle to create corresponding region
   ERegion* m_pRegion;
   m_pRegion = new ECircleRegion(m_CircleGauge.GetMeasuredCircle());
   

3. Perform the blob encoding inside that region.

   // Use EasyObject on the region
   EImageEncoder m_Encoder;
   m_Encoder.Encode(m_Image, *m_pRegion, m_CodedImage);
   

4. Draw the encoded object with different colors.

   ERGBColor colors[] = {
       ERGBColor(255, 0, 0),
       ERGBColor(0, 255, 0),
       ERGBColor(0, 0, 255),
       ERGBColor(255, 0, 255),
       ERGBColor(255, 255, 0),
       ERGBColor(0, 255, 255),
       ERGBColor(150, 50, 200),
       ERGBColor(50, 200, 150),
       ERGBColor(200, 150, 50)
   };
   
   for (int i = 0; i < codedImage.GetObjCount(); i++)
   {
     EObject& obj = codedImage.GetObj(i);
     int colorIdx = ((int)(obj.GetBoundingBoxCenterX() + obj.GetBoundingBoxCenterY()) / 10) % 9;
     codedImage.Draw(drawAdapter, colors[colorIdx], obj);
   }
