PosterizeCommandクラス








メンバ 
画像の各プレーンを指定した色階調数に量子化することによって、画像にポスター効果を加えます。たとえば2階調を指定すると、赤2階調、緑2階調、青2階調で画像が描画されます。
オブジェクトモデル
構文
'Declaration
 
Public Class PosterizeCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements Leadtools.ImageProcessing.IRasterCommand 
'Usage
 
Dim instance As PosterizeCommand
public sealed class PosterizeCommand : Leadtools.ImageProcessing.IRasterCommand  
@interface LTPosterizeCommand : LTRasterCommand
public class PosterizeCommand extends RasterCommand
function Leadtools.ImageProcessing.Color.PosterizeCommand()
解説

画像にLUTがあり画像データ上で作業する場合は、RasterImage.UseLookupTableをFalseに設定します。メソッドを呼び出した後で、以下のようにUselookupTableプロパティをTrueにリセットします。

rasterImage.UseLookupTable = false; Method(rasterImage); rasterImage.UseLookupTable = true;

詳細については、「アートエフェクトの適用」を参照してください。

サンプル

imageの上でPosterizeCommandを実行して、それをposterizeします。
