public class HtmlDocumentOptions : DocumentOptions

'Declaration
 
Public Class HtmlDocumentOptions 
   Inherits DocumentOptions

'Usage
 
Dim instance As HtmlDocumentOptions

public sealed class HtmlDocumentOptions : DocumentOptions

function Leadtools.Forms.DocumentWriters.HtmlDocumentOptions()

public ref class HtmlDocumentOptions : public DocumentOptions

The options set in the HtmlDocumentOptions class will be used when the user saves a document using the DocumentFormat.Html format.

To change the options used with the DOC format, perform the following steps:

Use the DocumentWriter.GetOptions method of the DocumentWriter object being used. Passing DocumentFormat.Html to the format parameter. Note that the resulting object from the base DocumentOptions class needs to be cast to HtmlDocumentOptions.
Use the various HtmlDocumentOptions properties to change the options.
Use DocumentWriter.SetOptions to set the new options in the engine.
Now you can call the DocumentWriter.BeginDocument method (with DocumentFormat.Html for the format parameter) to create a new document and add the pages.

The HtmlDocumentOptions class contains the following properties:

Property	Description
HtmlDocumentOptions.DocumentType	The type of the HTML document (Internet Explorer or Netscape compatible).
HtmlDocumentOptions.FontEmbedMode	Control how the fonts are embedded in the final document created by the LEADTOOLS Document Writer.
HtmlDocumentOptions.UseBackgroundColor and HtmlDocumentOptions.BackgroundColor	Set a background color in the final HTML document.
