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.
- A DynamicPDF Rasterizer for .NET v4.X Developer license.
Examples
This example demonstrates the usage of QuantizationAlgorithm enum in indexed image creation.Imports System
Imports ceTe.DynamicPDF.Rasterizer
Module MyModule
Sub Main()
' Create a PdfRasterizer object.
Dim rasterizer As New PdfRasterizer("InputPdfFile.pdf")
' Create a PngIndexedColorFormat object.
Dim pngIndexedColorFormat As New PngIndexedColorFormat(ImageFormat.DefaultColorPalette,100,DitheringAlgorithm.FloydSteinberg)
' Set the Colorpalette property to AutoPalette.
pngIndexedColorFormat.ColorPalette = New AutoPalette(QuantizationAlgorithm.Octree, 256)
' Create a PngImageFormat using PngIndexedColorFormat object.
Dim pngImageFormat As New PngImageFormat(pngIndexedColorFormat)
' Set the size.
Dim fixedImageSize As New FixedImageSize(595, 841)
' Save the image.
rasterizer.Draw("Output.png", pngImageFormat, fixedImageSize)
End Sub
