Leadtools.Windows.Media.Effects.Color Namespace : GammaCorrectExtendedCommandBitmapEffect Class




Adjusts the intensity of colors in an image by changing the gamma constant that is used to map the intensity values. Either of two different color spaces can be specified.

Syntax

Visual Basic (Declaration) 
Public Class GammaCorrectExtendedCommandBitmapEffect 
   Inherits RasterCommandBitmapEffect
Visual Basic (Usage)Copy Code
Dim instance As GammaCorrectExtendedCommandBitmapEffect
C# 
public class GammaCorrectExtendedCommandBitmapEffect : RasterCommandBitmapEffect
Managed Extensions for C++ 
public __gc class GammaCorrectExtendedCommandBitmapEffect : public RasterCommandBitmapEffect
C++/CLI 
public ref class GammaCorrectExtendedCommandBitmapEffect : public RasterCommandBitmapEffect

Remarks

  • This command is like the GammaCorrectCommandBitmapEffect method, but has been extended to allow the specification of the colorspace to be used.
  • Intensity values ideally follow a logarithmic progression, because the eye perceives changes in intensity as being equal when the ratio of change is equal. For example, we would see a change from 0.1 to 0.2 as being equal to a change from 0.2 to 0.4.
  • Gamma is a standard constant that is used to calculate the progression. For most CRTs the gamma constant is in the range of 2.2 to 2.5.
  • This command supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available only in the Document/Medical toolkits.
  • This command does not support 32-bit grayscale images.
