Reading local files (stylesheets, images) referenced in HTML

[manfromarce]

When converting a saved HTML page, it seems there is no way to specify the base directory.
For example, a stylesheet can be specified like this and be contained in the same folder as the HTML file:
<link rel="stylesheet" href="style.css">
and the same may occur for images.
So I created a custom class similar to HttpClientNetworkLoader which tries to access local files via FileStream, but it didn't work:

• it throws an exception before reaching GetResourceStream because the stylesheet is not found
• GetResourceStream is not called for local images so they are not preserved even if the full absolute URL is built

Is there a proper way to access both local and online resources like browsers do when opening a saved HTML page?

Local files are handled internally currently, and do not go through the network abstraction yet. This probably should be changed in the future, but in the meantime, the files are local to the current working directory of the application. This is something you can set via the Directory.SetCurrentDirectory API provided in .NET:

https://learn.microsoft.com/en-us/dotnet/api/system.io.directory.setcurrentdirectory?view=net-8.0

Call this before GeneratePdf. You can restore the previous value by retrieving it with Directory.GetCurrentDirectory prior to changing it and then resetting it afterwards.

Let me know if this addresses your issue.

Thank you, but unfortunately it still throws "Exception in handling stylesheet source".
If I remove the stylesheet, it works properly for local images.
