Licensing Info
This enum is a DynamicPDF Rasterizer feature. One of the following is required for non-evaluation usage:
- An active DynamicPDF Subscription
- An active DynamicPDF Professional or Professional Plus Subscription with DynamicPDF Rasterizer selected.

Examples
This example demonstrates how to rasterize a PDF document to Gif image using FloydSteinberg dithering.Imports System
Imports ceTe.DynamicPDF.Rasterizer
Module MyModule
Sub Main()
'Create a PdfRasterizer object.
Dim rasterizer As New PdfRasterizer("InputPdfFile.pdf")
'Create a GifImageFormat object.
Dim gifImageFormat As New GifImageFormat()
'Set the DitheringAlgorithm to FloydSteinberg.
gifImageFormat.DitheringAlgorithm = DitheringAlgorithm.FloydSteinberg
'Set the size.
Dim fixedImageSize As New FixedImageSize(595, 841)
'Save the image.
rasterizer.Draw("Output.Gif", gifImageFormat, fixedImageSize)
End Sub
End Module
