Incorrect Line Breaks in a Windows Forms TextBox

1. Use AdvancedScan in 64-bit Mode

Install the IronOCR.Extensions.AdvancedScan package for more reliable extraction, and run the application in 64-bit mode to avoid compatibility issues.

2. Normalize the Line Endings

Replace every \n in the result with \r\n before assigning the text to the control.

ocr.Language = OcrLanguage.ChineseSimplifiedBest;
using (var ocrInput = new OcrInput())
{
    ocrInput.LoadImage(txtPath.Text);
    ocrInput.Deskew();
    var result = ocr.ReadScreenShot(ocrInput);
    // Replace line feed with carriage return and line feed
    string ocrText = result.Text.Replace("\n", "\r\n");
    // Display the corrected text in a TextBox
    textBox1.Text = ocrText;
}

ocr.Language = OcrLanguage.ChineseSimplifiedBest;
using (var ocrInput = new OcrInput())
{
    ocrInput.LoadImage(txtPath.Text);
    ocrInput.Deskew();
    var result = ocr.ReadScreenShot(ocrInput);
    // Replace line feed with carriage return and line feed
    string ocrText = result.Text.Replace("\n", "\r\n");
    // Display the corrected text in a TextBox
    textBox1.Text = ocrText;
}

Imports System

ocr.Language = OcrLanguage.ChineseSimplifiedBest
Using ocrInput As New OcrInput()
    ocrInput.LoadImage(txtPath.Text)
    ocrInput.Deskew()
    Dim result = ocr.ReadScreenShot(ocrInput)
    ' Replace line feed with carriage return and line feed
    Dim ocrText As String = result.Text.Replace(vbLf, vbCrLf)
    ' Display the corrected text in a TextBox
    textBox1.Text = ocrText
End Using

The Replace("\n", "\r\n") call rewrites each line feed into the carriage-return/line-feed pair the TextBox expects, so the displayed text keeps the same line structure as the original image.

3. Verify the Output

Run the extraction again and compare the TextBox contents against the source image. The breaks should now line up with the original layout.
