PdfHtml Class

Quickly Create High Quality PDFs
An object of this class can be laid out in any position in a PDF document to render HTML content in place. Multiple objects of this type can be laid out in the same PDF page and even overlapped. If there is no background defined in the HTML document then the background of the rendered content in PDF will be transparent, making visible the existing content under it
