Implementation Guide

Convert Document from Stream

Overview

This feature demonstrates converting a document from an input stream to a PDF file. It’s particularly useful when dealing with files uploaded via web applications.

Step-by-Step Implementation

1. Set Up the Output Directory Define where your converted PDF will be stored:

string outputDirectory = "YOUR_OUTPUT_DIRECTORY";
string outputFile = Path.Combine(outputDirectory, "converted.pdf");

2. Define the Input Stream Source Here, we use a method GetFileStream to provide a stream from a file:

Func<Stream> inputStream = GetFileStream;

3. Initialize and Configure the Converter Initialize the converter with the input stream and configure it for PDF conversion:

using (Converter converter = new Converter(inputStream))
{
    PdfConvertOptions options = new PdfConvertOptions();
    converter.Convert(outputFile, options);
}

4. Implement GetFileStream Method This method reads a sample DOCX file into a stream:

private static Stream GetFileStream() => 
    File.OpenRead("YOUR_DOCUMENT_DIRECTORY/SAMPLE_DOCX");

Convert Document from MemoryStream

Overview

Convert documents from a MemoryStream, ideal for scenarios where files are processed in memory.

Step-by-Step Implementation

1. Set Up the Output Directory Similar to the stream conversion, define your output path:

string outputDirectory = "YOUR_OUTPUT_DIRECTORY";
string outputFile = Path.Combine(outputDirectory, "converted.pdf");

2. Define the Input Stream Source Use GetMemoryStream to provide a MemoryStream containing file data:

Func<Stream> inputStream = GetMemoryStream;

3. Initialize and Configure the Converter Initialize with the memory stream and set PDF conversion options:

using (Converter converter = new Converter(inputStream))
{
    PdfConvertOptions options = new PdfConvertOptions();
    converter.Convert(outputFile, options);
}

4. Implement GetMemoryStream Method Read a sample TXT file into a MemoryStream:

private static Stream GetMemoryStream()
{
    MemoryStream memStream = new MemoryStream();

    using (FileStream fStream = File.Open("YOUR_DOCUMENT_DIRECTORY/SAMPLE_TXT", FileMode.Open))
    {
        fStream.CopyTo(memStream);
    }
    return memStream;
}

Practical Applications

GroupDocs.Conversion for .NET can be integrated into various real-world scenarios:

  1. Web Application Uploads: Convert uploaded documents to PDFs on-the-fly.
  2. Document Management Systems: Automate the conversion of diverse document formats.
  3. Enterprise Reporting: Standardize reports by converting them to a uniform format like PDF.

Performance Considerations

To optimize performance when using GroupDocs.Conversion:

  • Resource Usage: Monitor memory usage, especially with large files or multiple conversions.
  • Memory Management: Dispose of streams and objects promptly to free resources.
  • Batch Processing: Convert documents in batches if possible to minimize overhead.

Conclusion

You’ve now equipped yourself with the knowledge to convert documents from streams and MemoryStream using GroupDocs.Conversion for .NET. This powerful tool can significantly enhance your document processing capabilities within .NET applications.

Next steps include exploring other conversion formats and integrating these features into larger projects. Experiment with different configurations to best fit your needs!
