HtmlToPdfConverterHtmlViewerZoom Property

Gets or sets the zoom percentage, from 10 to 200, decimals allowed, like the zoom of a browser when it prints: a lower zoom fits more content on a page, at a smaller size. When the zoom is not set, it is computed at conversion time from the page layout and the browser window width. Setting a value ends the automatic layout of the layout methods: the value is used as it is, until a layout method is called again. The default value is 100
