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
