OCR: How to import the OCR result from hOCR file?
In This Topic
OCR results can be imported from hOCR file.
Here is C#/VB.NET code that shows how to import OCR result from hOCR file and save imported result to a text file as formatted text:
// OCR result
Vintasoft.Imaging.Ocr.Results.OcrDocument ocrResult = null;
// path to hOCR file
string hOcrFilePath = @"..\..\Resources\ocrResult.hocr";
// open hOCR file
using (System.IO.Stream stream = System.IO.File.Open(hOcrFilePath, System.IO.FileMode.Open))
{
// create the HOcr codec
Vintasoft.Imaging.Ocr.Results.HOcrCodec hOcrCodec = new Vintasoft.Imaging.Ocr.Results.HOcrCodec();
// import the OCR result from hOCR file
ocrResult = hOcrCodec.Import(stream);
}
// if OCR result is imported successfully
if (ocrResult != null)
{
// get text of the first page
string firstPageText = ocrResult.Pages[0].GetFormattedText();
// save text to a text file
System.IO.File.WriteAllText("ocrResult.txt", firstPageText, System.Text.Encoding.UTF8);
}
' OCR result
Dim ocrResult As Vintasoft.Imaging.Ocr.Results.OcrDocument = Nothing
' path to hOCR file
Dim hOcrFilePath As String = "..\..\Resources\ocrResult.hocr"
' open hOCR file
Using stream As System.IO.Stream = System.IO.File.Open(hOcrFilePath, System.IO.FileMode.Open)
' create the HOcr codec
Dim hOcrCodec As New Vintasoft.Imaging.Ocr.Results.HOcrCodec()
' import the OCR result from hOCR file
ocrResult = hOcrCodec.Import(stream)
End Using
' if OCR result is imported successfully
If ocrResult IsNot Nothing Then
' get text of the first page
Dim firstPageText As String = ocrResult.Pages(0).GetFormattedText()
' save text to a text file
System.IO.File.WriteAllText("ocrResult.txt", firstPageText, System.Text.Encoding.UTF8)
End If
