Aspose.PDF BmpDevice.Process infinite loop

Aspose.PDF Product Family
1

For some simple PDF documents (perhaps invalid), when using BmpDevice.Process for a page, the method call never returns.

        using Aspose.Pdf.Document pdfDocument = new(inputFile);
        using MemoryStream pdfMemoryStream = new();
        Resolution resolution = new(96);
        BmpDevice bmpDevice = new(resolution);
        bmpDevice.Process(pdfDocument.Pages[1], pdfMemoryStream);
        Bitmap pdfBitmap = (Bitmap)Bitmap.FromStream(pdfMemoryStream);

Note the same file will also fail extracting text:

        using Aspose.Pdf.Document thePdfDocument = new(inputFile);
        TextAbsorber textAbsorber = new() { TextSearchOptions = new(false) { IgnoreResourceFontErrors = true } };
        thePdfDocument.Pages[1].Accept(textAbsorber);

Do you mean it hangs or it throws some error?

Same behavior - it hangs apparently in an infinite loop
