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
