How to Generate Grayscale PDF Files in C#

// This example demonstrates how to generate a grayscale PDF from a URL using IronPDF in C#.

// Add the IronPDF library to your project. Ensure IronPDF is installed via NuGet
// using the Package Manager Console:
// Install-Package IronPdf

using IronPdf; // Import the IronPdf namespace to access PDF generation classes

class Program
{
    static void Main(string[] args)
    {
        // Create an instance of ChromePdfRenderer, which handles PDF rendering
        var renderer = new ChromePdfRenderer();

        // Set the renderer to render PDFs in grayscale
        renderer.RenderingOptions.Grayscale = true;

        // Render a PDF from a URL. In this case, the Iron Software website is used.
        var pdfDocument = renderer.RenderUrlAsPdf("https://ironsoftware.com");

        // Extract the first page of the rendered PDF document
        var firstPage = pdfDocument.ExtractPages(0, 1);

        // Save the extracted page as a new PDF file named 'test.pdf'
        firstPage.SaveAs("test.pdf");

        // Output a message indicating the PDF has been created
        Console.WriteLine("The grayscale PDF has been successfully created as 'test.pdf'.");
    }
}
