Partial Page Conversion with Html to Pdf Converter


Partial Page Conversion with Html to Pdf Converter

Select.Pdf Html to Pdf Converter for .NET can be used to convert only a specific section of a web page to pdf.

The section that will be converted to pdf is specified by the html element ID. The element can be anything (image, table, table row, div, text, etc). To set the element id in Select.Pdf Library, the VisibleWebElementId property of the HtmlToPdfOptions object must be used.

Note
For HTML to PDF conversion, partial web page rendering is supported only by the WebKit and WebKit Restricted rendering engines. It is not currently applied when rendering HTML to PDF with the Blink or Chromium engines. For HTML to image conversion, the equivalent VisibleWebElementId property on HtmlToImage is supported by all four rendering engines.
