Remarks

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:

  1. 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.
  2. Use the various HtmlDocumentOptions properties to change the options.
  3. Use DocumentWriter.SetOptions to set the new options in the engine.
  4. 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
EmbedFonts Indicates whether fonts are to be embedded in the document.
FontEmbedMode Control what fonts are embedded in the document.
FontTypes Font types to embed in the document.
EmbedImages Indicate whether images are to be embedded in the document.
ImageType Format to use when saving images in the document.
EmbedCSS Indicate whether CSS elements are to be embedded in the document.
DropObjects Controls which object types to drop from the document.
UseBackgroundColor and BackgroundColor Controls the background color in the document.

Note that this format does not support calling DocumentWriter.InsertPage.

Example

This example will create a new HyperText Markup Language document (HTML) file using the various supported options.

C#
VB

using Leadtools.Codecs; 
 
public void HtmlDocumentOptionsExample()

   var codecs = new RasterCodecs(); 
   codecs.Options.RasterizeDocument.Load.Resolution = 300; 
 
   // Get the number of pages in the input document 
   var pageCount = codecs.GetTotalPages(inputFileName); 
 
   // Create a new instance of the LEADTOOLS Document Writer 
   var docWriter = new DocumentWriter(); 
 
   // Change the HTML options
