    Console.WriteLine("J2C file loaded successfully.");
}

Implementation Guide

Load J2C File

Overview: This feature demonstrates loading a JPEG 2000 Image File for conversion.

Step-by-Step Instructions:

  1. Initialize the Converter: Use the Converter class to load your .j2c file.
    string sourceFilePath = "YOUR_DOCUMENT_DIRECTORY\sample.j2c"; // Replace with your actual file path

using (Converter converter = new Converter(sourceFilePath))
{
    Console.WriteLine("J2C file loaded successfully.");
}

Set Conversion Options for JPG Format

Overview: Configure the conversion options to convert a file into JPG format.

Step-by-Step Instructions:

  1. Create ImageConvertOptions: Define the output format as JPG.
    using GroupDocs.Conversion.Options.Convert;

ImageConvertOptions options = new ImageConvertOptions { Format = FileTypes.ImageFileType.Jpg };
Console.WriteLine("Conversion options for JPG set successfully.");

Convert J2C to JPG Format

Overview: Perform the conversion from a loaded J2C file into the JPG format.

Step-by-Step Instructions:

  1. Define Output Stream: Specify where converted pages will be saved.

    string outputFolder = "YOUR_OUTPUT_DIRECTORY"; // Replace with your actual output directory path
string outputFileTemplate = Path.Combine(outputFolder, "converted-page-{0}.jpg");

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

  2. Perform Conversion: Use the Converter object to execute conversion using defined options.

    using (Converter converter = new Converter(sourceFilePath)) // Reuse source file path from previous step
{
    converter.Convert(getPageStream, options); // Convert and save as JPG
    Console.WriteLine("Conversion to JPG completed successfully.");
}

Troubleshooting Tips:

  • Ensure the output directory exists before running the conversion.
  • Check if the .j2c file is not corrupted or locked by another process.
