  Hello!

  The quality of the image is very low so the quality of recognition might be not very good. Please check the article in the Developer`s Help: Guided Tour → Advanced Techniques → Best Practices → Image Recommendations.

  If you need to extract all text from this image you may add the text block of the image size and recognize it. Please, see the following code snippet in C++:

  // Load Engine
  frDocument->AddImageFile( imageFilePath, 0, 0 );
  //Analyzing
  frDocument->Analyze( 0 ) );
  //Add text block
  CSafePtr<IFRPages> frPages;     
  frDocument->get_Pages( &frPages );
  CSafePtr<IFRPage> frPage;
  frPages->Item( 0, &frPage );
  CSafePtr<ILayout> layout;
  frPage->get_Layout ( &layout );
  CSafePtr<ILayoutBlocks> blocks;
  layout->get_Blocks( &blocks ); 
  blocks->DeleteAll(); 
  CSafePtr<IRegion> region;
  FREngine->CreateRegion( &region );
  region->AddRect( 0, 0, pictureWidth, pictureHeight );
  CSafePtr<IBlock> block;
  blocks->AddNew(BT_Text, region, 0, &block);
  //Recognition
  frDocument->Recognize();
  //Export

  You may get pictureWidth and pictureHeight from the properties of Image object. Please check the article in the Developer`s Help: API Reference → Image-Related Objects → Image.

  Note that in case of the image with low quality Engine may recognize some extra text.

  Hope the information will be useful.
