(Inherited from BaseInPlacePartialFilter.) |
| ApplyInPlace(Bitmap) |
Apply filter to an image.
(Inherited from BaseInPlacePartialFilter.) |
| ApplyInPlace(BitmapData) |
Apply filter to an image.
(Inherited from BaseInPlacePartialFilter.) |
| ApplyInPlace(UnmanagedImage) |
Apply filter to an unmanaged image.
(Inherited from BaseInPlacePartialFilter.) |
| ApplyInPlace(Bitmap, Rectangle) |
Apply filter to an image or its part.
(Inherited from BaseInPlacePartialFilter.) |
| ApplyInPlace(BitmapData, Rectangle) |
Apply filter to an image or its part.
(Inherited from BaseInPlacePartialFilter.) |
| ApplyInPlace(UnmanagedImage, Rectangle) |
Apply filter to an unmanaged image or its part.
(Inherited from BaseInPlacePartialFilter.) |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| ProcessFilter |
Process the filter on the specified image.
(Overrides BaseInPlacePartialFilterProcessFilter(UnmanagedImage, Rectangle).) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
Extension Methods| Name | Description | |
|---|---|---|
 | HasMethod |
Checks whether an object implements a method with the given name.
(Defined by ExtensionMethods.) |
| IsEqual |
Compares two objects for equality, performing an elementwise
comparison if the elements are vectors or matrices.
(Defined by Matrix.) |
| To(Type) | Overloaded.
Converts an object into another type, irrespective of whether
the conversion can be done at compile time or not. This can be
used to convert generic types to numeric types during runtime.
(Defined by ExtensionMethods.) |
| ToT | Overloaded.
Converts an object into another type, irrespective of whether
the conversion can be done at compile time or not. This can be
used to convert generic types to numeric types during runtime.

RemarksThe class implements simple posterization of an image by splitting each color plane into adjacent areas of the specified size. After the process is done, each color plane will contain maximum of 256/PosterizationInterval levels. For example, if grayscale image is posterized with posterization interval equal to 64, then result image will contain maximum of 4 tones. If color image is posterized with the same posterization interval, then it will contain maximum of 43=64 colors. See FillingType property to get information about the way how to control color used to fill posterization areas.
Posterization is a process in photograph development which converts normal photographs into an image consisting of distinct, but flat, areas of different tones or colors.
The filter accepts 8 bpp grayscale and 24/32 bpp color images.
Sample usage:
// create filter SimplePosterization filter = new SimplePosterization( ); // process image filter.ApplyInPlace( sourceImage );
