Thetype exposes the following members.
Creates a new instance of ConvolutionFilterCommand.
Creates a new instance of ConvolutionFilterCommand from serialization information.
Creates a new instance of ConvolutionFilterCommand specifying the matrix and intensity.
Reports whether or not this command will be applied to any supplied PixelFormat image(Inherited from ImageCommand.)
Returns true if the command can be applied to any PixelFormat.(Inherited from ImageCommand.)
Gets or sets a bit flag indicating the channels to process.
Gets a value indicating if the source image data is processed in-place as opposed to returning a new image.(Inherited from ImageCommand.)
Gets or sets a value controlling the intensity of the filter.
Gets or sets the matrix to apply to the image.
Gets or sets the ProgressEventHandler delegate which can be used to view or cancel the progress of the current process.(Inherited from ImageCommand.)
(Inherited from ImageRegionCommand.)
Gets or sets a RegionOfInterest which will only process the indicated region of the image.
Returns an array of PixelFormats supported by this command.(Overrides ImageCommandSupportedPixelFormats.)
Gets or sets a value indicating if the traditional version is used.
Apply the command to the given image.(Inherited from ImageCommand.)
|ApplyToImage|| Obsolete. |
Applies the command to the source AtalaImage.(Inherited from ImageCommand.)
The method is called by the default implementation of Apply. It determines if it is necessary to create a copy of the source image in a different pixel format and if so, determines the best new pixel format and allocates that image.(Inherited from ImageCommand.)
Called by the default implementation of Apply, ConstructFinalImage constructs the image that will be used as the destination image for the command.(Overrides ImageCommandConstructFinalImage(AtalaImage).)
Constructs the results object for this command.(Inherited from ImageCommand.)
Determines whether the specified object is equal to the current object.(Inherited from Object.)
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)
This method is called to change the pixel format of the source image.(Inherited from ImageCommand.)
Serves as the default hash function.(Inherited from Object.)
Fills a SerializationInfo object with information about this command.(Overrides ImageRegionCommandGetObjectData(SerializationInfo, StreamingContext).)
Gets the Type of the current instance.(Inherited from Object.)
Aggregates ImageCommand data into the supplied SerializationInfo object.(Inherited from ImageCommand.)
Returns a value indicating if the specified pixel format is supported.(Inherited from ImageCommand.)
Creates a shallow copy of the current Object.(Inherited from Object.)
PerformActualCommand does the actual work of the image processing command.(Overrides ImageCommandPerformActualCommand(AtalaImage, AtalaImage, Rectangle, ImageResults).)
Choose the best pixel format to use for this command when the supplied source image's pixel format is unacceptable.(Inherited from ImageCommand.)
Chooses a pixel format that is preferred for this command.(Overrides ImageCommandSelectPreferredPixelFormat(AtalaImage, PixelFormat, PixelFormat).)
Returns a string that represents the current object.(Inherited from Object.)
Verify the integrity of an AtalaImage.(Inherited from ImageCommand.)
Verify the integrity of properties in the command before processing an image.(Overrides ImageCommandVerifyProperties(AtalaImage).)
This should only be used on continuous-tone images (RGBA, grayscale, RGB, etc.).
If Traditional is true, this can be used to do things like a Gaussian blur, etc., depending on the matrix used.
The number of columns and the number of rows in the matrix must both be odd.
The filter is applied as follows :
M = matrix ( 3 x 3, in this example)M = 1 1 1 this is a sharpening matrix 1 -8 1 1 1 1
The matrix is centered on the current pixel. In this example, M is the center of the matrix.
k is the inteisity.
P = pixels . Since the matrix is centered on the current pixel, P(x,y), the pixels used in this calculation will be :P(x-1,y-1) P(x, y-1) P(x+1, y-1) P(x-1,y) P(x, y) P(x+1, y) P(x-1,y+1) P(x, y+1) P(x+1, y+1)
t = sum ( M[i] * P[i] ) [for all elements of the matrix]
if "traditional" processing (see uFlags) , outPixel = k * t ,else , outPixel = curPixel - (k * t)
outPixel is then clipped to 0..255
Matrix M in this example demonstrates the sharpening filter used by this library, if bTraditional is FALSE.
Besides the ability to use matricies of arbitrary size, this object differs from %ConvolutionMatrixCommand% in the way the final calculation is performed.
