Feature 2: Converting PNG to HTML Format

Overview

After loading, convert the image into an HTML format by specifying conversion options and executing the process.

using GroupDocs.Conversion.Options.Convert;

string outputFolder = "YOUR_OUTPUT_DIRECTORY"; // Placeholder path
string outputFile = Path.Combine(outputFolder, "png-converted-to.html");
WebConvertOptions options = new WebConvertOptions();
try {
    if (converter != null) {
        converter.Convert(outputFile, options);
    }
} catch (Exception ex) {
    Console.WriteLine("Error during conversion: " + ex.Message);
}

Explanation

  • Output Configuration: Set output directory and file name for the HTML document.
