Examples

This example demonstrates the usage of PngColorFormat class for creating a PNG image.

Imports System
Imports ceTe.DynamicPDF.Rasterizer

Module MyModule

    Sub Main()

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

       ' Create a FixedImageSize object with required width and height.
       Dim fixedImageSize As New FixedImageSize(595, 841)

       'Create a PngImageFormat object with indexed color.
       Dim oPngImageFormat As New PngImageFormat(PngColorFormat.Indexed)

       ' Save the image.
       rasterizer.Draw("Output.png", oPngImageFormat, 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");

       // Create a FixedImageSize object with required width and height.
       FixedImageSize fixedImageSize = new FixedImageSize(595, 841);

       //Create a PngImageFormat object with indexed color.
       PngImageFormat oPngImageFormat = new PngImageFormat(PngColorFormat.Indexed);

       // Save the image.
       rasterizer.Draw("Output.png", oPngImageFormat, fixedImageSize);
   }

}
