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) |

(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.
(Defined by ExtensionMethods.) |
The image processing routine applies the specified BaseFilter to a source image according to the specified mask - if a pixel/value in the specified mask image/array is set to 0, then the original pixel's value is kept; otherwise the pixel is filtered using the specified base filter.
Mask can be specified as .NET's managed Bitmap, as UnmanagedImage or as byte array. In the case if mask is specified as image, it must be 8 bpp grayscale image. In all case mask size must be the same as size of the image to process.
Note |
---|
Pixel formats accepted by this filter are specified by the BaseFilter. |
Sample usage:
// create the filter MaskedFilter maskedFilter = new MaskedFilter( new Sepia( ), maskImage ); // apply the filter maskedFilter.ApplyInPlace( image );
