Basic Initialization and Setup

With the library installed and your environment configured, initialize GroupDocs.Conversion for .NET:

using System;
using GroupDocs.Conversion;

class Program
{
    static void Main(string[] args)
    {
        // Initialize the license (if applicable)
        License license = new License();
        license.SetLicense("path_to_your_license_file.lic");

        Console.WriteLine("GroupDocs.Conversion for .NET is ready to use!");
    }
}

This setup ensures your application effectively leverages GroupDocs’ features.

Implementation Guide

In this section, we’ll walk through the practical steps required to convert a CGM file into PSD format using GroupDocs.Conversion. We break down the process for clarity.

Load Source File

Overview: This feature demonstrates how to load your source CGM file into the conversion process.

Step 1: Define Path and Initialize Converter

using System;
using GroupDocs.Conversion;

public class LoadSourceFileFeature
{
    public void Run()
    {
        // Define the path for the input CGM file
        string cgmFilePath = "YOUR_DOCUMENT_DIRECTORY/sample.cgm";

        // Initialize the Converter object with the source file path
        using (Converter converter = new Converter(cgmFilePath))
        {
            // The converter is now ready to perform conversion operations
        }
    }
}
  • Why: Initializing the Converter class with your CGM file prepares it for subsequent conversion steps.

Set Conversion Options

Overview: Configure necessary options to specify output in PSD format.

Step 2: Specify Output Format

using GroupDocs.Conversion.Options.Convert;

public class SetConversionOptionsFeature
{
    public void Run()
    {
        // Create an instance of ImageConvertOptions
        ImageConvertOptions options = new ImageConvertOptions();

        // Specify the output format as PSD
        options.Format = GroupDocs.Conversion.FileTypes.ImageFileType.Psd;
    }
}
  • Why: Configuring ImageConvertOptions ensures your file converts to the desired format.

Convert File

Overview: Execute the conversion process, saving the output files in the specified location.

Step 3: Perform Conversion and Save Output

using System.IO;
using GroupDocs.Conversion;
using GroupDocs.Conversion.Options.Convert;

public class ConvertFileFeature
{
    public void Run()
    {
        // Define output directory and template for output files
        string outputFolder = "YOUR_OUTPUT_DIRECTORY";
        string outputFileTemplate = Path.Combine(outputFolder, "converted-page-{0}.psd");

        // Create a function to generate output file streams based on page context
        Func<SavePageContext, Stream> getPageStream = savePageContext => 
            new FileStream(string.Format(outputFileTemplate, savePageContext.Page), FileMode.Create);

        // Load the source CGM file (assuming it's already defined in the LoadSourceFileFeature)
        string cgmFilePath = "YOUR_DOCUMENT_DIRECTORY/sample.cgm";
        using (Converter converter = new Converter(cgmFilePath))
        {
            // Create conversion options for PSD format
            ImageConvertOptions options = new ImageConvertOptions { Format = GroupDocs.Conversion.FileTypes.ImageFileType.Psd };

            // Perform the conversion to PSD format with the specified output stream function
            converter.Convert(getPageStream, options);
        }
    }
}
  • Why: This step ties everything together by executing file conversion and saving each page as a separate PSD file.

Troubleshooting Tips

  • Ensure all paths are correctly defined and accessible.
  • Verify that your .NET environment is compatible with GroupDocs.Conversion version 25.3.0.
  • Check for any licensing issues if you encounter restricted functionality.
