| 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.) |

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 filter filters pixels inside/outside of specified RGB color range - it keeps pixels with colors inside/outside of specified range and fills the rest with specified color.
The filter accepts 24 and 32 bpp color images for processing.
Sample usage:
// create filter ColorFiltering filter = new ColorFiltering( ); // set color ranges to keep filter.Red = new IntRange( 100, 255 ); filter.Green = new IntRange( 0, 75 ); filter.Blue = new IntRange( 0, 75 ); // apply the filter filter.ApplyInPlace( image );
