How to split a PDF document in Winrt
1 min read
We can extract the rotated image text in readable in OCR by enabling the AutoDetectRotation property.
Please find the below code snippet to auto correct the image rotation.
C#:
using (OCRProcessor processor = new OCRProcessor(@"..\..\Tesseract binaries\"))
{
//Load the PDF document
PdfLoadedDocument ldoc = new PdfLoadedDocument("..\..\Input.pdf");
//Language to process the OCR
processor.Settings.Language = Languages.English;
//Enable to AutoDetectRotation
processor.Settings.AutoDetectRotation = true;
// Process OCR by providing loaded PDF document, Data dictionary and language
String str = processor.PerformOCR(ldoc, @"..\..\Tessdata\");
//Save the PDF document.
ldoc.Save("Output.pdf");
ldoc.Close(true);
}
Note:
The rotated image text can be readable, only if the osd.tranineddata file must be present in the Tessdata folder. We have attached osd.traineddata file in the below link.
