It seems you are experiencing an issue where part of the text disappears when converting a PDF file using Aspose version 24.3.0, while the conversion works correctly with version 24.2.0. This could be due to changes or bugs introduced in the newer version.

To troubleshoot this issue, you can try the following steps:

  1. Check for Updates: Ensure that you are using the latest version of Aspose.PDF, as the issue may have been addressed in a subsequent release after 24.3.0.

  2. Validate the PDF: Before conversion, validate the PDF document to check for any issues that might affect the conversion process. You can use the validate method to generate a log file that can help identify potential problems.

  3. Use Different Conversion Options: Experiment with different PDF format conversion options. For instance, if you are currently using PDF/A-1b, try converting to other formats like PDF/A-3b or PDF/A-2a to see if the issue persists.

  4. Review Conversion Logs: If you have conversion logs generated during the process, review them for any warnings or errors that might indicate why the text is disappearing.

  5. Revert to Previous Version: If the issue is critical and you need an immediate solution, consider reverting to version 24.2.0 until the problem is resolved in a future release.

Here is a sample code snippet for validating and converting a PDF document:

using (var document = new Document(inputFilePath))
{
    // Validate the document
    document.Validate("validation_log.xml", PdfFormat.PDF_A_1B);
    
    // Convert the document
    document.Convert(pdfFormatConversionOptions);
    
    // Save the converted document
    document.Save(outputFilePath);
}

If the problem continues, consider reaching out to Aspose support with the specific details of your issue, including the PDF file and the conversion options you are using.

If you have any further questions or need additional assistance, feel free to ask!
