如何用 Aspose.OCR 从图像中提取表数据

PM> Install-Package Aspose.OCR

using Aspose.OCR;

OcrInput input = new OcrInput(InputType.SingleImage);
input.Add("table1.png");
input.Add("table2.jpg");

RecognitionSettings settings = new RecognitionSettings();
settings.DetectAreasMode = DetectAreasMode.TABLE;
settings.Language = Language.English; // Adjust if table contains non-English text

AsposeOcr ocr = new AsposeOcr();
List<RecognitionResult> results = ocr.Recognize(input, settings);

foreach (RecognitionResult result in results)
{
    Console.WriteLine(result.RecognitionText); // Raw table as text
    result.Save("table.csv", SaveFormat.Csv); // Save as CSV
    result.Save("table.xlsx", SaveFormat.Xlsx); // Save as Excel
}

try
{
    AsposeOcr ocr = new AsposeOcr();
    List<RecognitionResult> results = ocr.Recognize(input, settings);
    // further processing...
}
catch (Exception ex)
{
    Console.WriteLine($"Error: {ex.Message}");
}

// Example: Add all images from a folder
foreach (string file in Directory.GetFiles("./tables", "*.png"))
{
    input.Add(file);
}

using System.Collections.Generic;

class Program
{
    static void Main(string[] args)

        try
        {

            input.Add("table1.png");
            input.Add("table2.jpg");

            RecognitionSettings settings = new RecognitionSettings();

            }
