Hello Support,
We are encountering a small issue when converting an EML file to PDF using the Aspose PDF converter. Some lines are being ignored during the conversion and do not appear in the PDF file.
After analyzing, I found that the issue is caused by lines in the EML file containing a <span> with a <style> tag that is not properly passing through the conversion process. I will provide an example below.
The following line is ignored during conversion:
<p style="margin-top: 0pt; margin-bottom: 0pt; font-size: 12pt;"><span style="font-family: 'Times New Roman'; -aw-import: ignore;">Le jugement n'a pas à être signifié puisque Madame était présente lors de l'audience.</span></p>
When modified as shown below, it successfully passes the conversion:
<p style="margin-top: 0pt; margin-bottom: 0pt; font-size: 12pt;"><span style="font-family: Constantia; font-weight: bold; text-decoration: underline;">Le jugement n'a pas à être signifié puisque Madame était présente lors de l'audience.</span></p>
Regards

Could you please provide version of Aspose PDF you are using and example of file and code so we can recreate this issue?

@djalilgpj
Do I understand correctly that you are using Aspose Words to convert to PDF, not Aspose PDF library?
Its the code that we have , yes
@djalilgpj
In that case I’ll reassign your question to Aspose Words forum
@djalilgpj It looks like the problem occurs upon converting EML to intermediate MHTML file. You can reproduce the problem using the following code:
com.aspose.email.MailMessage msg = com.aspose.email.MailMessage.load("C:\\Temp\\in.eml");
msg.save("C:\\Temp\\tmp.mhtml", com.aspose.email.SaveOptions.getDefaultMhtml());
com.aspose.words.Document doc = new com.aspose.words.Document("C:\\Temp\\tmp.mhtml");
doc.save("C:\\Temp\\out.pdf");
So I will move the topic into Aspose.Email forum. My colleagues will help you shortly.

@djalilgpj We have completed the WORDSNET-27493 analysis. The HTML inside is slightly broken and contains our CSS property '-aw-import: ignore;’ which we use for internal purposes. This is the reason why the word Madame is not being imported.
<div>
<p style="margin-top: 0pt; margin-bottom: 0pt; font-size: 12pt;"><span style="font-family: 'Times New Roman'; -aw-import: ignore;">Madame, </span></p>
</div>
You should avoid using '-aw-import: ignore;'.
Hello,
It’s very clear now. Thank you very much!

By the way, we receive these emails rather than produce them, so we can’t control this kind of use of tags.
However, I was wondering if you could use other personalized tags for these cases, so as to be independent of the standard tags.
Regards,
@djalilgpj Actually, -aw-import: ignore; is not a standard css attribute. This attribute is for Aspose.Words HTML roundtrip. So it looks like Aspose.Words was used to produce the e-mail on the other side.
Can we use aw- as a prefix for all your specific tags, so we can detect if a tag is specific and apply our logic accordingly?
@djalilgpj -aw- prefix is used for Aspose.Words specific css tags for storing roundtrip information in HTML.
The issues you have found earlier (filed as WORDSNET-27493) have been fixed in this Aspose.Words for .NET 24.12 update also available on NuGet.
