Q: How to use the MemoryStream object to store the rendering result instead of the file system?

Q: How to check the list of resources that are loaded along with an HTML document?

A: We have a specialized Network Service that gives you full control over the all request/response messages. You can use it to trace the requests, create a custom cache, substitute the content of response messages and much more.

Q: How to override the document style?

A: There is a ‘ User Style Sheet’ property that can be useful exactly for this purpose.

Q: My document does not parse properly, I see black-squares instead of letters! How can I fix it?

A: We parse a document headers to detect the character-set (encoding) of the document. If the encoding is not defined we use UTF-8, which is defined as a default for HTML5 specification. If you know that encoding is different from the default UTF-8, please specify it directly as it described here.

Q: I want to see page numbers at the bottom of the document, how to do this?

A: Since CSS is used to describe the visual layout of the document, we designed specialized CSS Extensions that can be used to write information on page margins.
