Set to Grayscale

VB C#

using IronPdf;

var renderer = new ChromePdfRenderer();

// Set Color and Grayscale
renderer.RenderingOptions.GrayScale = true;

renderer.RenderHtmlFileAsPdf("my-content.html").SaveAs("my-content.pdf");

Imports IronPdf

Private renderer = New ChromePdfRenderer()

' Set Color and Grayscale
renderer.RenderingOptions.GrayScale = True

renderer.RenderHtmlFileAsPdf("my-content.html").SaveAs("my-content.pdf")

Install-Package IronPdf

Set to Grayscale

When rendering an HTML page to PDF with IronPDF, output options for the ChromePdfRenderer class can be changed to create a custom document that fits your needs. These options include paper size, DPI, headers and footers, and other Chromium-specific browser setup options. IronPDF also has the option to set your PDF color to grayscale.

This example shows you how to render your PDF document to grayscale.

Converting your document to grayscale makes the colors wash down to black and white. This makes printing on black and white printers easy. The grayscale option in the ChromePdfRenderer class outputs a black and white PDF document. However, the default value is false. If you want the document to render in grayscale, you would have to manually put in the grayscale settings.

using IronPdf;

class Program
{
    static void Main(string[] args)
    {
        // Create an instance of ChromePdfRenderer
        var Renderer = new ChromePdfRenderer();

        // Set the rendering to grayscale
        Renderer.RenderingOptions.SetPaperSize(PaperSize.A4);
        Renderer.RenderingOptions.RenderInGrayscale = true; // This option enables grayscale rendering

        // Render an HTML file to PDF
        var PdfDocument = Renderer.RenderHtmlAsPdf("<html><body><h1>Hello, World!</h1></body></html>");

        // Save the PDF document to a specific path
        PdfDocument.SaveAs("GrayscalePDF.pdf");
    }
}

using IronPdf;

class Program
{
    static void Main(string[] args)
    {
        // Create an instance of ChromePdfRenderer
        var Renderer = new ChromePdfRenderer();

        // Set the rendering to grayscale
        Renderer.RenderingOptions.SetPaperSize(PaperSize.A4);
        Renderer.RenderingOptions.RenderInGrayscale = true; // This option enables grayscale rendering

        // Render an HTML file to PDF
        var PdfDocument = Renderer.RenderHtmlAsPdf("<html><body><h1>Hello, World!</h1></body></html>");

        // Save the PDF document to a specific path
        PdfDocument.SaveAs("GrayscalePDF.pdf");
    }
}

This code snippet demonstrates how to render an HTML document to a grayscale PDF using the IronPDF library.

ChromePdfRenderer Instance: We begin by creating an instance of ChromePdfRenderer. This class provides methods for converting HTML to PDFs.
Set Rendering Options: The RenderingOptions property of the renderer is used to specify how we want the PDF to be rendered. The SetPaperSize method sets the document to A4 size. The RenderInGrayscale property is set to true to enable grayscale rendering. By default, PDFs are not rendered in grayscale unless specified.
Render HTML: We call the RenderHtmlAsPdf method on the Renderer object, passing in a simple HTML string. This method converts the HTML content to a PDF format.
Save the PDF: Finally, the SaveAs method is used to save the rendered PDF to a file named "GrayscalePDF.pdf" on the disk.
