Examples

This example demonstrates how to rasterize a PDF document to PNG indexed 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 PngIndexedColorFormat object.
        Dim pngColorFormat As PngIndexedColorFormat  = New PngIndexedColorFormat(DitheringAlgorithm.FloydSteinberg,100)
        pngColorFormat.ColorPalette = Palette.WindowsPalette

        ' 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 PngIndexedColorFormat object.
        PngIndexedColorFormat pngColorFormat = new PngIndexedColorFormat(DitheringAlgorithm.FloydSteinberg,100);
        pngColorFormat.ColorPalette = Palette.WindowsPalette;

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

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