程式範例

這個C#程式碼範例從圖像或PDF文件中讀取梵文字母文字。

// Ensure the IronOcr package is installed 
// PM> Install-Package IronOcr.Languages.Devanagari

using IronOcr;

var Ocr = new IronTesseract();
// Set the OCR language to Devanagari
Ocr.Language = OcrLanguage.Devanagari;

// Define the input file
using (var Input = new OcrInput(@"images\Devanagari.png"))
{
    // Process the input file
    var Result = Ocr.Read(Input);

    // Extract the recognized text
    var AllText = Result.Text;

    // Output the recognized text
    Console.WriteLine(AllText);
}

// Ensure the IronOcr package is installed 
// PM> Install-Package IronOcr.Languages.Devanagari

using IronOcr;

var Ocr = new IronTesseract();
// Set the OCR language to Devanagari
Ocr.Language = OcrLanguage.Devanagari;

// Define the input file
using (var Input = new OcrInput(@"images\Devanagari.png"))
{
    // Process the input file
    var Result = Ocr.Read(Input);

    // Extract the recognized text
    var AllText = Result.Text;

    // Output the recognized text
    Console.WriteLine(AllText);
}
