Misformatting of conversion HTML to PDF

Aspose.Words Product Family
1

We have unexpected results in converting HTML to PDF regarding styling of the PDF.

  • Styling in PDF is not according to HTML styling
  • Pictures do not respect sizing
  • All pictures get underscores

We use:
Aspose.Words v11.3.0.0
Please advise.

Hi Hans,

Thanks for your inquiry. I have managed to reproduce the following issues at my side. I have logged these issues as follow:

WORDSNET-9010 : Aspose.Words.Document does not import the html styles correctly
WORDSNET-9011 : Html to Doc/Docx/Pdf file conversion issue with images (All pictures get underscores)

I have linked this forum thread to the same issues and you will be notified via this forum thread once these issues are resolved. We apologize for your inconvenience.

  • Pictures do not respect sizing*

I have not found this issue at my end in output Pdf file. It would be great if you please share some more detail about this issue. You have not shared the images used in your html. Please also share images along with html here for testing. I will investigate the issue on my side and provide you more information.

I uploaded the image files. The HTML is already available in the earlier post.

Thank you for the update. We did some testing with the new update. Because we are not eligible for a free upgrade on our licence, we tested with the trial version.

We found a better result based on the new update. There are still some issues however. We would appreciate if you could look into them.

  1. The quality of the logo is not OK
  2. Hyperlinks are not in the correct font color
  3. Offset of the hyperlink text line is off by a few pixels
  4. We suspect bold font is “too bold” to fit, leading to incorrect word wrapping.
  5. The second picture in the example html file is not displayed in the resulting PDF.

Our findings are attached in the examples in the zip file and commented in the PDF file in the zip.

We are looking forward to your response.

Kind regards

I added an example to explain the issue with the offset. This is typical for hyperlinks we assume, because we see similar behavior in the footer of the HTML and the PDF.

Hi Hans,

*hansvanoosterom:

  1. The quality of the logo is not OK*

It is to inform you that our development team has completed the work on the issue (WORDSNET-9307) and has come to a conclusion that this issue and the undesired behavior you’re observing is actually not a bug in Aspose.Words. So, we have closed this issue as ‘Not a Bug’. The image quality is good. Please check the image at 200% zoom in Adobe reader.

Moreover, please try using PdfSaveOptions.DownsampleImages = false when saving. By default, images are downsampled when converting to pdf.

We have also noticed that the following issue is not a bug. The output Pdf is close to input html.

WORDSNET-9310 : Extra empty spaces appear after conversion from Html to Docx/PDF

Hi Hans,

Thanks for sharing the detail. I am using the same operating system and .NET framework. I have attached the output Pdf file with this post for your kind reference. I have used the following code example to convert html to Pdf. The picture is visible in output Pdf file.

var doc = new Document(MyDir + "35021.html");
doc.Save(MyDir + "out.pdf");
14

Thanks for the quick response. Since we are testing with the trial version: could the trial version be responseable for the behaviour we noticed? Otherwise we wait for a new version with solutions for the other issues we registered before a new test on this issue as well.

Kind regards.
