CodeBrix.PdfDocuments

Create and process PDF documents using .NET, without the need of interop.

CodeBrix.PdfDocuments is a .NET library for creating, reading, merging, and manipulating PDF documents. CodeBrix.PdfDocCreate is a companion library that provides a document object model for building richly formatted PDF documents with styled text, tables, charts, and images. CodeBrix.PdfRasterizer is a companion library that renders PDF pages to images (PNG, JPEG, BMP, GIF, TIFF) using the PDFium native rendering engine, with support for thumbnails, page information, and cross-platform operation.

CodeBrix.PdfDocuments has dependencies on the CodeBrix.Imaging package for image and font handling, and the CodeBrix.Compression package for data compression. CodeBrix.PdfRasterizer has dependencies on CodeBrix.PdfDocuments and the CodeBrix.Imaging package, and bundles pre-built PDFium native binaries for Windows, macOS, Linux, and Android.

CodeBrix.PdfDocuments, CodeBrix.PdfDocCreate, and CodeBrix.PdfRasterizer are provided as .NET 10 libraries and associated CodeBrix.PdfDocuments.MitLicenseForever, CodeBrix.PdfDocCreate.MitLicenseForever, and CodeBrix.PdfRasterizer.MitLicenseForever NuGet packages.

CodeBrix.PdfDocuments supports applications and assemblies that target Microsoft .NET version 10.0 and later. Microsoft .NET version 10.0 is a Long-Term Supported (LTS) version of .NET, and was released on Nov 11, 2025; and will be actively supported by Microsoft until Nov 14, 2028. Please update your C#/.NET code and projects to the latest LTS version of Microsoft .NET.

CodeBrix.PdfDocuments is a fork of the code of the popular PdfSharpCore library version 1.3.67 and the MigraDocCore libraries version 1.3.67 - see below for licensing details.

Sample Code

Create a Simple PDF

using CodeBrix.PdfDocuments.Drawing;
using CodeBrix.PdfDocuments.Pdf;

// Create a new PDF document
var document = new PdfDocument();

// Add a page and create a graphics renderer
var page = document.AddPage();
var renderer = XGraphics.FromPdfPage(page);

// Draw text on the page
renderer.DrawString(
    "Hello, PDF!",
    new XFont("Arial", 24),
    XBrushes.Black,
    new XPoint(50, 50));

// Save the document
document.Save("HelloPdf.pdf");

Create a PDF with Images

using CodeBrix.PdfDocuments.Drawing;
using CodeBrix.PdfDocuments.Pdf;

var document = new PdfDocument();
var page = document.AddPage();
var renderer = XGraphics.FromPdfPage(page);

// Draw text
renderer.DrawString("PDF with Image", new XFont("Arial", 16), XBrushes.Black, new XPoint(12, 24));

// Draw an image from file
renderer.DrawImage(XImage.FromFile("photo.png"), new XPoint(12, 50));

document.Save("ImageDocument.pdf");

Read and Merge PDF Documents

using CodeBrix.PdfDocuments.Pdf;
using CodeBrix.PdfDocuments.Pdf.IO;

// Open existing PDF files and merge them
var outputDocument = new PdfDocument();

foreach (var pdfPath in new[] { "document1.pdf", "document2.pdf" })
{
    using var fs = File.OpenRead(pdfPath);
    var inputDocument = PdfReader.Open(fs, PdfDocumentOpenMode.Import);

    for (var i = 0; i < inputDocument.PageCount; i++)
    {
        outputDocument.AddPage(inputDocument.Pages[i]);
    }
}

outputDocument.Save("merged.pdf");

Create a Styled Document with CodeBrix.PdfDocCreate

using CodeBrix.PdfDocCreate.DocumentObjectModel;
using CodeBrix.PdfDocCreate.Rendering;

// Create a document with styled content
var doc = new Document
{
    Info =
    {
        Title = "Sales Report",
        Subject = "Quarterly Sales Data",
        Author = "CodeBrix"
    }
};

// Define styles
var titleStyle = doc.AddStyle("Title", "Normal");
titleStyle.Font.Size = 24;
titleStyle.Font.Bold = true;
titleStyle.ParagraphFormat.SpaceAfter = 6;
titleStyle.ParagraphFormat.Alignment = ParagraphAlignment.Center;

var bodyStyle = doc.Styles["Normal"];
bodyStyle.Font.Size = 10;
bodyStyle.ParagraphFormat.SpaceAfter = 4;

// Add content
var section = doc.AddSection();
var titleParagraph = section.AddParagraph("Quarterly Sales Report");
titleParagraph.Style = "Title";

var bodyParagraph = section.AddParagraph("This report summarizes quarterly sales data.");
bodyParagraph.Style = "Normal";

// Render to PDF
var pdfRenderer = new PdfDocumentRenderer { Document = doc };
pdfRenderer.RenderDocument();
pdfRenderer.PdfDocument.Save("SalesReport.pdf");

Rasterize PDF Pages to Image Files

using CodeBrix.PdfRasterizer;

// Create a rasterizer instance
using var rasterizer = new PageRasterizer();

// Configure output settings
rasterizer.OutputDirectory = @"C:\Output\Images";
rasterizer.Dpi = 300;

// Rasterize all pages of a PDF to PNG files
await rasterizer.RasterizeToImageFiles("report.pdf");

Rasterize a Single PDF Page to an In-Memory Image

using CodeBrix.Imaging;
using CodeBrix.Imaging.Formats.Jpeg;
using CodeBrix.PdfRasterizer;

using var rasterizer = new PageRasterizer();

// Rasterize page 1 as a JPEG image
using var image = await rasterizer.RasterizeToImage(
    "report.pdf",
    pageNumber: 1,
    desiredImageFormat: JpegFormat.Instance);

// Save the image to a file
await image.SaveAsync("page1.jpg");

// Or access image properties
Console.WriteLine($"Image size: {image.Width} x {image.Height}");

Generate Thumbnails

using CodeBrix.Imaging;
using CodeBrix.PdfRasterizer;

using var rasterizer = new PageRasterizer();

// Generate thumbnails with custom max dimensions (150x200 pixels)
var maxDimensions = new ThumbnailMaxDimensions(150, 200);
IList<Image> thumbnails = await rasterizer.RasterizeToThumbnails(
    "report.pdf",
    maxDimensions: maxDimensions);

foreach (var thumbnail in thumbnails)
{
    Console.WriteLine($"Thumbnail size: {thumbnail.Width} x {thumbnail.Height}");
    thumbnail.Dispose();
}

Get PDF Page Information

using CodeBrix.PdfRasterizer;

using var rasterizer = new PageRasterizer();

// Get the number of pages
int pageCount = await rasterizer.GetPageCount("report.pdf");
Console.WriteLine($"Page count: {pageCount}");

// Get dimensions of a specific page
PdfPageDimensions dims = await rasterizer.GetPageDimensions("report.pdf", pageNumber: 1);
Console.WriteLine($"Page size: {dims.WidthInInches:F1}\" x {dims.HeightInInches:F1}\"");
Console.WriteLine($"At 300 DPI: {dims.GetWidthInPixels(300)} x {dims.GetHeightInPixels(300)} pixels");

Rasterize Pages from a PdfDocument Object

using CodeBrix.Imaging;
using CodeBrix.PdfDocuments.Pdf;
using CodeBrix.PdfRasterizer;

// Create a PDF document programmatically
var document = new PdfDocument();
var page = document.AddPage();
// ... draw content on the page ...

// Rasterize the in-memory document directly
using var rasterizer = new PageRasterizer();
IList<Image> images = await rasterizer.RasterizeToImages(document);

foreach (var image in images)
{
    // Process the image...
    image.Dispose();
}
