Examples

The code sample below illustrates the changes introduced in this release:

Read region types from recognition results

using Aspose.OCR;
using System;

AsposeOcr recognitionEngine = new AsposeOcr();

OcrInput input = new OcrInput(InputType.SingleImage);
input.Add("document.png");

RecognitionSettings settings = new RecognitionSettings
{
    DetectAreasMode = DetectAreasMode.MULTICOLUMN
};

RecognitionResult result = recognitionEngine.Recognize(input, settings)[0];

foreach (RecognitionResult.RegionResult region in result.RecognitionRegionsResult)
{
    Console.WriteLine($"Region type: {region.RegionType}");
    Console.WriteLine(region.TextInRegion);
}

foreach (RecognitionResult.LinesResult line in result.RecognitionLinesResult)
{
    Console.WriteLine($"Line region type: {line.RegionType.Key}");
    Console.WriteLine($"Region bounds: {line.RegionType.Value}");
    Console.WriteLine(line.TextInLine);
}
