Apply filter to an image.
(Inherited from BaseInPlacePartialFilter.) | |
Apply(BitmapData) |
Apply filter to an image.
(Inherited from BaseInPlacePartialFilter.) | |
Apply(UnmanagedImage) |
Apply filter to an image in unmanaged memory.
(Inherited from BaseInPlacePartialFilter.) | |
Apply(UnmanagedImage, UnmanagedImage) |
Apply filter to an image in unmanaged memory.
(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.) |
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 is similar to Threshold filter in the way, that it also uses threshold value for image binarization. Unlike regular threshold filter, this filter uses cumulative pixel value in comparing with threshold value. If cumulative pixel value is below threshold value, then image pixel becomes black. If cumulative pixel value is equal or higher than threshold value, then image pixel becomes white and cumulative pixel value is decreased by 255. In the beginning of each image line the cumulative value is reset to 0.
The filter accepts 8 bpp grayscale images for processing.
Sample usage:
// create filter Threshold filter = new Threshold( 100 ); // apply the filter filter.ApplyInPlace( image );
