Examples

This example demonstrates how to rasterize a pdf document to PNG image with an image specific palette.

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 pngIndexedColorFormat As PngIndexedColorFormat  = New PngIndexedColorFormat(ImageFormat.DefaultColorPalette,100,DitheringAlgorithm.FloydSteinberg)
		
        ' Set the ColorPalette property to  AutoPalette.
        pngIndexedColorFormat.ColorPalette = New AutoPalette(QuantizationAlgorithm.Octree, 256)

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

        ' 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 pngIndexedColorFormat = new PngIndexedColorFormat(ImageFormat.DefaultColorPalette,100,DitheringAlgorithm.FloydSteinberg);

        // Set the ColorPalette property to  AutoPalette.
        pngIndexedColorFormat.ColorPalette = new AutoPalette(QuantizationAlgorithm.Octree, 256);

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

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