Here’s how you can initialize and set up GroupDocs.Conversion in your C# project:

// Basic setup of the Converter object
class Program
{
    static void Main(string[] args)
    {
        string filePath = Path.Combine(Directory.GetCurrentDirectory(), "sample.cf2");
        using (Converter converter = new Converter(filePath))
        {
            // Conversion logic will go here
        }
    }
}

Implementation Guide

Let’s break down the conversion process into logical steps.

Load CF2 File

This feature demonstrates loading a CF2 file using GroupDocs.Conversion library. Here’s how you do it:

Initialize the Converter Object

Start by creating an instance of the Converter class with your CF2 file path.

class Program
{
    static void Main(string[] args)
    {
        string filePath = Path.Combine(Directory.GetCurrentDirectory(), "sample.cf2");
        using (Converter converter = new Converter(filePath))
        {
            // Conversion logic will go here
        }
    }
}
  • Why: Initializing the Converter object is essential as it prepares your file for further operations like conversion.

Convert CF2 to PNG

Next, we’ll convert the loaded CF2 file into a PNG format using GroupDocs.Conversion options.

Define Output Stream Function

Set up a function that handles the output stream for each page converted:

class Program
{
    static void Main(string[] args)
    {
        string outputFolder = Path.Combine(Directory.GetCurrentDirectory(), "output");
        string outputFileTemplate = Path.Combine(outputFolder, "converted-page-{0}.png");

        Func<SavePageContext, Stream> getPageStream = savePageContext => 
            new FileStream(string.Format(outputFileTemplate, savePageContext.Page), FileMode.Create);

        // Continue with conversion setup...
    }
}
  • Why: This function ensures each page of your CF2 file is saved correctly as a PNG in the specified output directory.

Set Convert Options for PNG

Define the conversion options to specify that you want the output format as PNG:

class Program
{
    static void Main(string[] args)
    {
        ImageConvertOptions options = new ImageConvertOptions { Format = GroupDocs.Conversion.FileTypes.ImageFileType.Png };
        
        // Continue with conversion...
    }
}
  • Why: By setting ImageConvertOptions, you dictate how your file will be converted and ensure it meets your desired image specifications.

Perform the Conversion

Execute the conversion using the previously defined options:

class Program
{
    static void Main(string[] args)
    {
        string outputFolder = Path.Combine(Directory.GetCurrentDirectory(), "output");
        string outputFileTemplate = Path.Combine(outputFolder, "converted-page-{0}.png");

        Func<SavePageContext, Stream> getPageStream = savePageContext => 
            new FileStream(string.Format(outputFileTemplate, savePageContext.Page), FileMode.Create);

        ImageConvertOptions options = new ImageConvertOptions { Format = GroupDocs.Conversion.FileTypes.ImageFileType.Png };

        using (Converter converter = new Converter(Path.Combine(Directory.GetCurrentDirectory(), "sample.cf2")))
        {
            converter.Convert(getPageStream, options);
        }
    }
}
  • Why: This is where the actual transformation from CF2 to PNG happens. The Convert method uses all configurations you’ve specified.

Troubleshooting Tips

  • Ensure that the file path for your CF2 file and output directory are correct.
  • Check if GroupDocs.Conversion library dependencies are properly installed.

Practical Applications
