Hi,
Regarding the invalid URI hostname exception when saving to PDF, please try again with this bugfix:
https://www.gemboxsoftware.com/document/nightlybuilds/GBD33v1307.zip
Or this NuGet package:
Install-Package GemBox.Document -Version 33.0.1307-hotfix
Regarding the irregular HTML comments, note that we’re still working on it.
Regarding that last file which results in a long save time, I’m afraid the problem is again due to excessive usage of nested tables.
Anyway, I don’t think there is any point in creating another workaround that would handle this when it’s clear that you may have any kind of HTML content.
So, considering how you mentioned that you don’t care about the “fancy html formatting”, how about you export the document content as plain text?
For example, like this:
document.Content.LoadText(document.Content.ToString(), document.DefaultCharacterFormat);
document.Save("output.pdf");
Would that work for you?
Regards,
Mario
