VintaSoft Imaging .NET SDK and Plug-ins Discussions

hi guys ,i created a template using the project of test(sample), but do not was successful in write the code for use the template and extract the text from pdf files,
the project sample is a desktop application , this turn out the task hard, understand a code with desktop components associate.
i need a code project type "console application"
my code works , a little :S
but do not is efficient, i know exist a better way, I'm not getting make it works
forgive my poor english :(
so , the code ... this was my better solution until now


part 1

List<VintasoftImage> images = new List<VintasoftImage>();
                VintasoftImage imagem = new VintasoftImage(path + fileName + ext);
                imagem.RenderingSettings = new RenderingSettings(new Resolution(96 * fator, 96 * fator), InterpolationMode.HighQualityBicubic, SmoothingMode.HighQuality);
                FormRecognitionManager = new FormRecognitionManager();
                FormRecognitionManager.FormTemplates.LoadFromDocument(pathTemplate + template + extTemplate);
                images.Add(imagem);
                FormDocumentTemplate FormDocumentTemplate = FormDocumentTemplate.Deserialize(pathTemplate + template + extTemplate);

hi vladimir, thank you for your help, the problem with the examples is , the objects in the parameters ,is only instantiate? what i need configure in this objects?
i'm having troubles , the recognitionResult in all tries are null
the method RecognizeFormWithOcrFields, is the same of the documentation
we like of the your tools, of the possibilities, but i need get better results in my tests ,the purchase of the license is depending on that.

 
	//i use the variable "fator" ,because the resolution of image was modified  when i created the "template"
	 static int fator = 10;
	 static ChangePixelFormatToBlackWhiteCommand _binarizeCommand = new ChangePixelFormatToBlackWhiteCommand(BinarizationMode.Global);
	// the other variables are just paths of the images,of the tesseract and others.

the support helped me , the mistake was mine, i don't had understood that need configure the tesseract

OcrEngine ocrEngine = new TesseractOcr(TesseractOcrDllDirectory);
OcrFieldTemplate.OcrEngineManager = new OcrEngineManager(ocrEngine);
