DocumentFileInfo Class

Summary

The DocumentFileInfo class provides information for additional files generated by the Leadtools.Services.Forms.ServiceContracts.IOcrService.Recognize operation.

Syntax

C++

[DataContractAttribute(Namespace="http://Leadtools.Services.Forms.DataContracts/2009/01", Name="DocumentFileInfo")] 
public class DocumentFileInfo

  
<DataContractAttribute(Namespace="http://Leadtools.Services.Forms.DataContracts/2009/01", Name="DocumentFileInfo")> 
Public Class DocumentFileInfo

[DataContractAttribute(Namespace="http://Leadtools.Services.Forms.DataContracts/2009/01", Name="DocumentFileInfo")] 
public ref class DocumentFileInfo

Remarks

When DocumentConvertOptions.Format is set to OcrDocumentFormatType.Html32 or OcrDocumentFormatType.Html40, an additional directory will be generated. This directory will contain files necessary for the Html page:

Image Files

For example if the file name is "Test.Html" then a "Test_files" will be created. “Test_files” will contain the images files. The references to these files, by default will be named “Leadtools_Rename_This” in the html file. All of these references need to be renamed to match the generated files.
