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 PNG monochrome image format.

Imports System
Imports ceTe.DynamicPDF.Rasterizer

Module MyModule

    Sub Main()

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

        ' Create a PngMonochromeColorFormat object.
        Dim pngColorFormat As PngMonochromeColorFormat  = New PngMonochromeColorFormat(DitheringAlgorithm.FloydSteinberg,100)			

        ' Create a PngImageFormat object.
        Dim pngImageFormat As PngImageFormat = New PngImageFormat(pngColorFormat)

        ' Save the image.
        rasterizer.Draw("Output.png", pngImageFormat, ImageSize.Dpi72)   

    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");

        // Create a PngMonochromeColorFormat object.
        PngMonochromeColorFormat pngColorFormat = new PngMonochromeColorFormat(DitheringAlgorithm.FloydSteinberg,100);

        // Create a PngImageFormat object.
        PngImageFormat pngImageFormat = new PngImageFormat(pngColorFormat);

        // Save the image.
        rasterizer.Draw("Output.png", pngImageFormat, ImageSize.Dpi72);
