PdfSaveOptions options = new PdfSaveOptions();
options.SaveFormat = SaveFileFormat.Pdf;

if (ConversionConfiguration.IsPDFA)
{
options.Compliance = PdfCompliance.PdfA1a;
}
ConvertedFilePath = Path.ChangeExtension(OriginalFilePath, “pdf”);

It appears you are encountering an issue when trying to convert a VSDX file to PDF/A format, while the conversion to standard PDF works without any problems. The error message suggests that there is a problem with loading an image during the conversion process.

Cause: The issue may stem from unsupported or corrupted image formats within your VSDX file, or potentially from hidden pages or corrupt elements that are not compatible with PDF/A standards.

Solution: Here are some steps to troubleshoot and resolve this issue:

  1. Check Image Formats: Verify that all images used in your VSDX file are in supported formats. Unsupported or corrupted image formats can lead to loading failures.

  2. Update Aspose.Diagram: Ensure you are using the latest version of Aspose.Diagram, as newer releases may contain bug fixes or improvements related to PDF/A conversion.

  3. Set Compliance Correctly: Confirm that you are setting the compliance to PdfA1a as intended. If you are uncertain, try using PdfA1b to see if it resolves the issue.

  4. Export Hidden Pages: If your diagram contains hidden pages, set the ExportHiddenPage option to true to include them in the conversion.

  5. Check for Corrupt Elements: Open the VSDX file in Visio and inspect it for any corrupt elements or unsupported features that may not translate well into PDF/A.

Here’s a minimal code snippet to ensure you are setting the options correctly:

PdfSaveOptions options = new PdfSaveOptions();
options.SaveFormat = SaveFileFormat.Pdf;

if (ConversionConfiguration.IsPDFA)
{
    options.Compliance = PdfCompliance.PdfA1b; // Try PdfA1b if PdfA1a fails
    options.ExportHiddenPage = true; // Include hidden pages if necessary
}

ConvertedFilePath = Path.ChangeExtension(OriginalFilePath, "pdf");
diagram.Save(ConvertedFilePath, options);

Next Steps: If the issue persists after trying these steps, please share more details about the specific elements in your VSDX file that might be causing the problem. This information will help in diagnosing the issue further.

Let me know if this helps!
