Summary

Support for creating document files such as PDF, XPS, DOC, HTML, RTF, or Text from Scalable Vector Graphics (SVG), Windows Enhanced Meta Files (EMF) or raster images.

Syntax

Objective-C

C++/CLI

Java

Python

public class DocumentWriter

@interface LTDocumentWriter : NSObject

public class DocumentWriter

public ref class DocumentWriter

class DocumentWriter:

Remarks

The DocumentWriter class is used to create multipage and searchable documents from one or more SVG, EMF or raster image based pages. Refer to LEADTOOLS Document Writers for more information.

Support for various popular formats is included, such as PDF, DOC/DOCX, HTML, RTF, XPS or Text. For a list of all the document formats supported, refer to the DocumentFormat enumeration.

Example

This example shows how to create document file from SVG-based pages using basic functionality of the DocumentWriter class. For an example on creating documents from EMF objects, refer to DocumentWriterEmfPage and for an example on creating mixed documents from SVG, EMF and empty pages, refer to DocumentWriterRasterPage.
