PDF to HTML wrong conversion for some text - each character of text mapping in separate span instead of single span

Its really weird thing we observed while converting Pdf document to Html, as simple plain text getting divided in different different span by each character.

Please look into this and reply ASAP,

The plain text is: Printed Name

But it is divided in multiple spans instead of single span.


Can you please share your sample PDF document along with sample code snippet so that we can test the scenario in our environment and address it accordingly.

Can you please specify if you are using Aspose.PDF for .NET OR Java? Please share a sample code snippet with us as well.

We are using Aspose.pdf for .net

And already shared code snippet


We were able to reproduce the issue of multiple spans around every character while testing with 22.2 version of the API. However, the text in output HTML looked fine while rendering in the browser. We used below code snippet:

var original_book = new Aspose.Pdf.Document(dataDir + @"2022-02-25T09-47-36_AM_Hoaic_App_HO3-6.pdf");
HtmlSaveOptions htmlOptions = new HtmlSaveOptions();

htmlOptions.FixedLayout = true;
htmlOptions.PartsEmbeddingMode = Aspose.Pdf.HtmlSaveOptions.PartsEmbeddingModes.EmbedAllIntoHtml;
htmlOptions.RasterImagesSavingMode = Aspose.Pdf.HtmlSaveOptions.RasterImagesSavingModes.AsEmbeddedPartsOfPngPageBackground;
htmlOptions.RemoveEmptyAreasOnTopAndBottom = true;
htmlOptions.SplitIntoPages = false;
htmlOptions.SplitCssIntoPages = false;
string cssprefix = "aspose_pdf";
htmlOptions.CssClassNamesPrefix = cssprefix;

original_book.Save(dataDir + "outputHTML.html", htmlOptions);
