Foxit PDF rasterizer for .NET SDK

take your vector-based PDF files and convert them to a pixel-based IMAGE format

Foxit PDF Rasterizer for .NET SDK is a simple to use .NET library to quickly take your vector-based PDF files and convert them to a pixel-based format (an image format). This process can significantly reduce the overall size of the document and allows you to use the output image for other purposes where PDF documents may not be ideal.

Rasterize PDF to PNG Example (C# and VB.NET)

The following example demonstrates how to take a PDF file and rasterized it into a PNG file. Rasterizing a PDF file to a PNG can be done in just two simple lines of code.

C# Code:

  • 1: PdfRasterizer rasterizer = new PdfRasterizer(“DocumentA.pdf”);
  • 2: rasterizer.Draw(“DocumentA.png”, ImageFormat.Png, ImageSize.Dpi72);

VB.NET Code:

  • 1: Dim MyRasterizer As PdfRasterizer = New PdfRasterizer(“DocumentA.pdf”)
  • 2: MyRasterizer.Draw(“DocumentA.png”, ImageFormat.Png, ImageSize.Dpi72)
