Partially Convert of a HTML Page to PDF

EVO PDF Client for .NET Core

Sometimes is necessary to convert only a part of a HTML document like a table or div. With EVO HTML to PDF converter this is perfectly possible. The HTML element to be rendered to PDF is given by the HtmlToPdfConverterRenderedHtmlElementSelector property.

The RenderedHtmlElementSelector property can be set with any CSS selector. Please be aware that the CSS selectors are case sensitive and if many HTML elements are selected then only the first one will be actually converted.
