(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.) | |

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.

The filter does color channels' filtering by clearing (filling with specified values) values, which are inside/outside of the specified value's range. The filter allows to fill certain ranges of RGB color channels with specified value.
The filter is similar to ColorFiltering, but operates with not entire pixels, but with their RGB values individually. This means that pixel itself may not be filtered (will be kept), but one of its RGB values may be filtered if they are inside/outside of specified range.
The filter accepts 24 and 32 bpp color images for processing.
Sample usage:
// create filter ChannelFiltering filter = new ChannelFiltering( ); // set channels' ranges to keep filter.Red = new IntRange( 0, 255 ); filter.Green = new IntRange( 100, 255 ); filter.Blue = new IntRange( 100, 255 ); // apply the filter filter.ApplyInPlace( image );
