DocumentConverter Class

Summary

Supports conversion from any type of document to another using SVG, OCR and Raster technologies.

Syntax

C++/CLI

Java

Python

public class DocumentConverter : IDisposable

public ref class DocumentConverter

public class DocumentConverter

class DocumentConverter(IDisposable):

Remarks

The DocumentConverter allows conversion from any type of document to another with minimal amount of code.

The input and output document types can be any type of file formats supported by LEADTOOLS. but not limited to:

Adobe Acrobat PDF and PDF/A
Microsoft Office DOCX/DOC, XLSX/XLS and PPTX/PPT
CAD formats such as DXF, DWG and DWF
TIFF, JPEG, PNG, EXIF, BMP and hundred more raster image formats
Plain Text and RTF
HTML
ePub

The DocumentConverter class will analyze the input and output documents types and then automatically uses a combination of the LEADTOOLS Raster, SVG and OCR engines to convert the data using the best possible combination of accuracy and speed. Each conversion operation is called a Document Converter Job in the framework.
