Object Model

Syntax

Visual Basic
C#
Managed Extensions for C++
C++/CLI

'Declaration
 
Public Class ImGearReductionOptions

'Usage
 
Dim instance As ImGearReductionOptions

public class ImGearReductionOptions

public __gc class ImGearReductionOptions

public ref class ImGearReductionOptions

Remarks

The only options used by the ImGearRasterProcessing.Reduce method are the ones which correspond to the type of reduction as specified by the reductionMethod parameter of the ImGearRasterProcessing.Reduce method.

Example

C#
Visual Basic

// Reduce the bit depth of an image to 4 bit

// Create reduction options object and setup a few values for a 16 color 4-bit reduction.
ImGearReductionOptions igReductionOptions = new ImGearReductionOptions();
igReductionOptions.Octree.MaxColors = 16;
igReductionOptions.Octree.FastRemap = false;
igReductionOptions.Octree.ErrorDiffusion = true;
//Apply the reduction using Octree to get a 4-bit index image.
ImGearRasterProcessing.Reduce(igRasterPage, new ImGearColorSpace(ImGearColorSpaceIDs.I),
    new int[] { 4 }, ImGearReductionMethods.OCTREE, igReductionOptions);

' Reduce the bit depth of an image to 4 bit

' Create reduction options object and setup a few values for a 16 color 4-bit reduction.
Dim igReductionOptions As New ImGearReductionOptions()
igReductionOptions.Octree.MaxColors = 16
igReductionOptions.Octree.FastRemap = False
igReductionOptions.Octree.ErrorDiffusion = True
'Apply the reduction using Octree to get a 4-bit index image.
ImGearRasterProcessing.Reduce(igRasterPage, New ImGearColorSpace(ImGearColorSpaceIDs.I), New Integer() {4}, _
