This class is a DynamicPDF Rasterizer feature. One of the following is required for non-evaluation usage:


This example demonstrates how to rasterize a PDF document to Gif image using ImageFormat class.

Imports System
Imports ceTe.DynamicPDF.Rasterizer

Module MyModule

   Sub Main()
       'Create a PdfRasterizer object.
       Dim rasterizer As New PdfRasterizer("InputPdfFile.pdf")

       'Set the size.
       Dim fixedImageSize As New FixedImageSize(595, 841)

       'Save the image.
       rasterizer.Draw("Output.Gif", ImageFormat.Gif, fixedImageSize)

   End Sub
End Module
using System;
using ceTe.DynamicPDF.Rasterizer;

class MyClass
   static void Main(string[] args)
       //Create a PdfRasterizer object.
       PdfRasterizer rasterizer = new PdfRasterizer("InputPdfFile.pdf");

       //Set the size.
       FixedImageSize fixedImageSize = new FixedImageSize(595, 841);

       //Save the image.
       rasterizer.Draw("Output.Gif", ImageFormat.Gif, fixedImageSize);
