API to manipulate Publisher files in C#

Aspose.PUB for .NET lets you work with PUB files in your .NET applications. It supports manipulating .pub files with a simple and well-defined structure. 

Edit MetaData of PUB Files

Metadata of .pub files accessible by Aspose.PUB

Microsoft Publisher (.pub) files have metadata information about the file itself. There is examples of information that you can get using this API Solution:

Metadata	Description
Application Name	The name of the application that was used to create the document
Title	The title of the publication.
Author	The name of the person or entity who created the publication.
Version	Version value
Subject	A brief description or topic associated with the publication.
Keywords	Relevant keywords or tags to describe the content of the publication.
Comments	Additional notes related to the publication.
Creation Date	The date when the publication was originally created.
Modification Date	The date when the publication was last edited.
Last Author	The name of the person who last made changes to the document.
Template	Application-specific template from which the document was created.
Character Count	Provides the total number of characters in the document.
Word Count	Provides the total number of words in the document.
Page Count	Provides the total number of pages in the document.

Functionality to work with metadata of .pub files provided by Aspose.PUB for .NET

Metadata describes document properties such as title, company, language, and related information. The following example parses halloween-flyer.pub and updates eight properties through the DocSummaryInfo and SummaryInfo classes. These changes affect the parsed Document in memory; the example does not save a modified PUB file.

In these examples, DataDir is the input directory and OutputDir is the output directory. Set them to your own directories and ensure the output directory exists before running the stream example. Import the Aspose.Pub and System.IO namespaces when using the snippets in your application.

// Edit the metadata of a parsed PUB document in memory

// Parse the input Publisher document.
string fileName = Path.Combine(DataDir, "halloween-flyer.pub");
IPubParser parser = PubFactory.CreateParser(fileName);
Document document = parser.Parse();

// Update document metadata. These changes do not save a PUB file.
document.DocumentSummaryInfo.SetCategory("category");
document.DocumentSummaryInfo.SetCompany("company");
document.DocumentSummaryInfo.SetLanguage("language");

document.SummaryInfo.SetComments("comments");
document.SummaryInfo.SetKeywords("keywords");
document.SummaryInfo.SetLastAuthor("last author");
document.SummaryInfo.SetTitle("title");
document.SummaryInfo.SetSubject("subject");

Write output to stream

The following example converts a PUB document to TIFF and writes the result to a file stream. The using block closes the stream after conversion. Here is how the example works:

1. Construct the input path with Path.Combine(DataDir, "halloween-flyer.pub").
2. Create an IPubParser using PubFactory.CreateParser(fileName), then call parser.Parse() to obtain a Document object.
3. Construct outPath with Path.Combine(OutputDir, "halloween-flyer_out.tiff") and open the output stream with File.Create(outPath). This creates the file or truncates an existing file.
4. Call PubFactory.CreatePubConverter() to create a converter, then call ConvertToFormat(doc, outputStream, PubExportFormats.Tiff) to write TIFF data to the stream. The stream is disposed when the using block ends.

A similar way you can convert PUB to another format, using one of the supported PubExportFormats

// Convert a PUB document to TIFF using an output stream

// Parse the input Publisher document.
string fileName = Path.Combine(DataDir, "halloween-flyer.pub");
IPubParser parser = PubFactory.CreateParser(fileName);
Document doc = parser.Parse();

// Write TIFF output to a file stream and close it after conversion.
string outPath = Path.Combine(OutputDir, "halloween-flyer_out.tiff");
using (FileStream outputStream = File.Create(outPath))
{
    PubFactory.CreatePubConverter().ConvertToFormat(doc, outputStream, PubExportFormats.Tiff);
}
