DitheringAlgorithm Enum

Represents different dithering algorithms.

public enum DitheringAlgorithm
Public Enum DitheringAlgorithm

Inheritance: ObjectValueTypeEnumDitheringAlgorithm


DitheringAlgorithm.Bayer1Bayer's pattern based algorithm.
DitheringAlgorithm.FloydSteinberg0Floyd-Steinberg diffusion kind of algorithm.
DitheringAlgorithm.None2No Dithering.

Licensing Info

This enum is a DynamicPDF Rasterizer feature. One of the following is required for non-evaluation usage:


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
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 GifImageFormat object.
	 GifImageFormat gifImageFormat = new GifImageFormat();

	 //Set the DitheringAlgorithm to FloydSteinberg.
	 gifImageFormat.DitheringAlgorithm = DitheringAlgorithm.FloydSteinberg;

	 //Set the size.
	 FixedImageSize fixedImageSize = new FixedImageSize(595, 841);

	 //Save the image.
	 rasterizer.Draw("Output.Gif", gifImageFormat, fixedImageSize);
