Implementation Guide

Load and Convert OTT to PDF

Overview

This section covers how to load an Open Document Template (OTT) file and convert it into a Portable Document Format (PDF).

Step 1: Define Output Directory Specify where your converted files will be stored:

using System.IO;

string outputFolder = "YOUR_OUTPUT_DIRECTORY";

// Ensure the directory exists or create it if not present
if (!Directory.Exists(outputFolder))
{
    Directory.CreateDirectory(outputFolder);
}

Step 2: Initialize Converter and Convert Use GroupDocs.Conversion to load your OTT file and convert it:

string outputFile = Path.Combine(outputFolder, "ott-converted-to.pdf");

using (var converter = new Converter("YOUR_DOCUMENT_DIRECTORY/SAMPLE_OTT"))
{
    var options = new PdfConvertOptions();
    converter.Convert(outputFile, options);
}

Explanation:

  • Converter Class: Initializes with the path to your OTT file.
  • PdfConvertOptions: Configures PDF-specific settings for conversion. Customize these as needed.

Configure Output Directory

Setting up an output directory ensures converted files are stored in a specific location, avoiding clutter and overwrites.

Step 1: Check and Create Directory Ensure the directory exists:

if (!Directory.Exists(outputFolder))
{
    Directory.CreateDirectory(outputFolder);
}

Use Conversion Options

Customizing conversion options allows you to tailor the output PDF according to specific requirements like margins or page sizes.

Step 1: Customize PdfConvertOptions Modify settings using PdfConvertOptions:

var options = new PdfConvertOptions()
{
    MarginTop = 10,
    MarginBottom = 10,
    PageSize = PageSize.A4 // Set the desired page size
};

  2. Document Management Systems: Integrate GroupDocs.Conversion within systems to handle dynamic document types efficiently.
  3. Legal Document Processing: Use conversion features to standardize legal documents before distribution.

Performance Considerations

  • Optimize Memory Usage: Manage resources by disposing of objects promptly after use.
  • Batch Processing: Process multiple files in batches to reduce system load and increase throughput.
  • Parallel Execution: Utilize .NET’s parallel processing capabilities for handling large-scale conversions effectively.
