PdfFocusCHtmlOptionseHtmlRenderMode Enumeration

Gets or sets the rendering mode for the output HTML: Fixed or Flowing. Default value: Fixed.

Namespace: SautinSoft
Assembly: SautinSoft.PdfFocus (in SautinSoft.PdfFocus.dll) Version: 2024.3.28
Syntax
public enum eHtmlRenderMode
Members
Member nameValueDescription
Fixed0 The Fixed HyperText Markup Language (HTML) format. The most accurate mode. The resulting HTML document looks exact as PDF pixel by pixel.
Flowing1 The Flowing HyperText Markup Language (HTML) format. The most useful and common type of HTML document for editing. The resulting HTML document looks as if it was typed by human.
Remarks
The HTML-Fixed is better to use for rendering, because it completely mirrors the PDF layout with structure of pages.

The HTML-Flowing is better for further processing: editing and combining. The markup of such documents has a flowing structure. It's much simple for understanding by a human. But the resulting HTML document may look not exactly the same as input PDF pixel by pixel.

Default value: Fixed.
