PDF to HTML example
The ToHtmlString method is primarily designed to allow users to analyze HTML elements in an existing PDF document. It serves as a useful tool for debugging or PDF comparison purposes. In addition to converting a PDF document to HTML string, we offer a direct method for users to save a PDF document as HTML file using the SaveAsHtml method. This provides flexibility for users to choose the most suitable approach based on their specific needs.

Both the ToHtmlString and SaveAsHtml methods offer various configuration options. Below are the available properties:
- BackgroundColor: Specifies the background color.
- PdfPageMargin: Specifies the page margin.
Additionally, the properties below are intended for the 'title' parameter in the ToHtmlString and SaveAsHtml methods. This will add a new title at the beginning of the content. They will not modify the title or h1 of the input PDF document.
- H1Color: Specifies the title color.
- H1FontSize: Specifies the title font size.

These methods will produce an HTML string with inline CSS. The output HTML uses SVG terms/tags instead of the usual HTML tags. Despite this difference, it is a valid HTML string and can be rendered the same way in a web browser. However, it's important for users to be aware that the returned HTML string from this method may differ from the HTML input when using a PDF document that was rendered using the RenderHtmlAsPdf method, due to the reasons mentioned above.
