Extension Methods
  NameDescription
Public Extension MethodHasMethod
Checks whether an object implements a method with the given name.
(Defined by ExtensionMethods.)
Public Extension MethodIsEqual
Compares two objects for equality, performing an elementwise comparison if the elements are vectors or matrices.
(Defined by Matrix.)
Public Extension MethodTo(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.

Remarks

The filter filters pixels, which color is inside/outside of RGB sphere with specified center and radius - it keeps pixels with colors inside/outside of the specified sphere and fills the rest with specified color.

The filter accepts 24 and 32 bpp color images for processing.

Sample usage:

// create filter
EuclideanColorFiltering filter = new EuclideanColorFiltering( );
// set center colol and radius
filter.CenterColor = new RGB( 215, 30, 30 );
filter.Radius = 100;
// apply the filter
filter.ApplyInPlace( image );
