}
  2. Explain Parameters and Purpose:
    • xltFilePath: Path to your source XLT file.
    • Converter object: Manages loading and conversion processes.

Set Conversion Options

Overview: Define the conversion parameters, specifically setting it to convert into JPG format.

Step-by-Step Implementation:

  1. Define Image Convert Options
    using GroupDocs.Conversion.Options.Convert;

// Specify target format as JPG
ImageConvertOptions jpgOptions = new ImageConvertOptions { Format = GroupDocs.Conversion.FileTypes.ImageFileType.Jpg };
  2. Key Configuration:
    • ImageConvertOptions: Configures conversion parameters.
    • Format: Defines the output file type, in this case, JPG.

Convert XLT to JPG

Overview: Execute the conversion from XLT to a series of JPG images using defined options and paths.

Step-by-Step Implementation:

    string outputFolder = "YOUR_OUTPUT_DIRECTORY";
string outputFileTemplate = Path.Combine(outputFolder, "converted-page-{0}.jpg");

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

converter.Convert(getPageStream, jpgOptions);
  3. Explain Parameters and Method Purpose:
    • outputFolder: Directory where the JPG files will be saved.
    • getPageStream: Function to handle each page’s output stream during conversion.
