Purpose

This sample program demonstrates how to:

• Read a text inside the ROI of an image using EasyOCR (superseded by EasyOCR2).

• Use a configuration based on a OCR font file (.ocr).

Code highlights

1. Load an EasyOCR font file.

   // Load the font file
   EOCR m_Ocr;
   m_Ocr.Load(ToUtf8(LoadFont.GetPathName()).GetString());
   

2. Read the text.

   // Set the threshold mode
   m_Ocr.SetThreshold(EThresholdMode_MinResidue);
   
   // Perform recognition
   #define NB_MAX_RECO_CHARS 256
   m_szOCRRecoText = m_Ocr.Recognize(&m_SrcRoi1, NB_MAX_RECO_CHARS, EOCRClass_AllClasses);
   

3. Draw the image, the ROI and the characters bounding boxes

   // Display the source image
   Src.Draw(drawAdapter);
   
   // Draw the roi frame with its handles
   Roi.DrawFrame(drawAdapter, TRUE);
   
   // Draw the character bounding boxes if needed
   if (GetDocument()->m_bRead)
   {
     const ERGBColor greenPen(0, 255, 0);
     Ocr.DrawChars(drawAdapter, greenPen);
   }
