Convert pdf with text upside down inside to HTML incorrect

Aspose.PDF Product Family

I used Aspose Pdf version 17.2 for converting pdf with some text upside-down inside to html with embeded all resource. But the text in HTML can not display correctly.

using (Document pdfDocument = new Document(source))
{
// Instantiate HTML Save options object
HtmlSaveOptions saveOptions = new HtmlSaveOptions();
// Enable option to embed all resources inside the HTML
saveOptions.PartsEmbeddingMode = HtmlSaveOptions.PartsEmbeddingModes.EmbedAllIntoHtml;
// This is just optimization for IE and can be omitted
saveOptions.LettersPositioningMethod =
HtmlSaveOptions.LettersPositioningMethods.UseEmUnitsAndCompensationOfRoundingErrorsInCss;
saveOptions.RasterImagesSavingMode =
HtmlSaveOptions.RasterImagesSavingModes.AsEmbeddedPartsOfPngPageBackground;
saveOptions.FontSavingMode = HtmlSaveOptions.FontSavingModes.SaveInAllFormats;

                saveOptions.FixedLayout = true;

                saveOptions.PageBorderIfAny = new SaveOptions.BorderInfo(new SaveOptions.BorderPartStyle
                {
                    LineType = SaveOptions.HtmlBorderLineType.Solid,
                    Color = System.Drawing.Color.Gray,
                    WidthInPoints = 1
                });

                pdfDocument.Save(singleHtmlFileName, saveOptions);
            }
