Overview and description of filters and transforms to process images (or selected portions). It includes methods to smooth, sharpen, detect/enhance edges, remove noise and combine two or more images.

Classes

 ClassDescription
ClassAddMessageCommand Adds a message (text or file) to the image. This command is available in the Document/Medical Toolkits.
ClassAddNoiseCommand Adds random pixels to an image, letting you specify the percentage of coverage and the color plane.
ClassAlphaBlendCommand Combines image data from two images, using a specific opacity value.
ClassAntiAliasingCommand Applies an anti-aliasing filter to the specified image. This method is available in the Document Toolkits.
ClassAverageCommand Changes the color of each pixel in an image to the average color of pixels in its neighborhood. This results in a blur effect.
ClassBinaryFilterCommand Imposes a binary filter on an image. This command is available in the Document/Medical Toolkits.
ClassColorHalftoneCommand Shows the effect of using an enlarged halftone screen on each image channel. The filter divides the image into rectangles and replaces each rectangle with circles. Each channel has a separate grid of circles, and has its own angle setting. The size of each circle is proportional to the brightness of the rectangle that it is replacing. This method is available in the Document/Medical toolkits.
ClassCombineCommand Combines image data from two images (source and destination), letting you specify the areas to be combined, the operations to be performed when combining the data, and which color planes (R or G or B or R, G, and B) are used.
ClassContourFilterCommand Performs a contour segment filter on the source image. This command is available in the Medical Toolkits.
ClassCubismCommand Remaps the image into a collection of rotated rectangles (cubic faces) so that it appears to have been created in the Cubist art style.
ClassDeinterlaceCommand Deinterlaces video source images by removing the black lines.
ClassDirectionEdgeStatisticalCommand Detects the variation of colors in the specified direction using statistical indices. It is similar to EdgeDetectStatisticalCommand, but this command allows you to specify the direction angle.
ClassDisplacementCommand Displaces image pixels horizontally and vertically according to the values of the displacement map image.
ClassEdgeDetectEffectCommand Performs edge detection on the image.
ClassEdgeDetectorCommand Applies the specified edge filter to an image. This command is available in the Document Toolkits.
ClassEdgeDetectStatisticalCommand Detects edges by examining the variation of colors in all directions using statistical indices.
ClassEffectsUtilities Effect utility class.
ClassEmbossCommand Applies an emboss effect to an image, letting you specify the depth and direction of the effect.
ClassExtractMessageCommand Extracts a message (text or file) from the image, if the image has an embedded message. This command is available in the Document/Medical Toolkits.
ClassFadedMaskCommand Creates a fade mask image in which the color of each pixel is changed with respect to its position in the image. This change depends on the fade rate.
ClassFeatherAlphaBlendCommand Combines image data from two images with feathering. The two images can be combined with variable opacity applied by specifying the region of a fade mask image.
ClassFeretsDiameterCommand Computes the Feret's diameter of an object (the maximum distance between the points of the perimeter of the region), and finds its end points.
ClassGaussianCommand Smooths or blurs an image by applying a Gaussian filter to the specified image.
ClassHighPassCommand Removes low frequency details in an image, resulting in a sharpened image.
ClassMaskConvolutionCommand Applies various 3d effects to an image.
ClassMosaicCommand Imposes a mosaic effect on an image by dividing the image into tiles of a specified size and changing the color of all pixels in each tile to the average color of pixels within the tile.
ClassMotionBlurCommand Applies a filter, which creates the illusion of movement in an image.
ClassObjectInformationCommand Determines the position, orientation and roundness of the object in the image.
ClassOffsetCommand Shifts the image data horizontally and vertically.
ClassOilifyCommand Applies an oil-painting effect to the image.
ClassPicturizeListCommand Picturizes the image using a specific thumbnail image.
ClassPicturizeSingleCommand Picturizes the image using a specific thumbnail image.
ClassRegionContourPointsCommand Gets the contour coordinates of a region.
ClassRegionHolesRemovalCommand Removes all the holes in a region. This command is available in the Document/Medical Toolkits.
ClassResizeRegionCommand Resizes an image region by a specific number of pixels.
ClassSharpenCommand Increases or decreases the sharpness of a specific image.
ClassSkeletonCommand Finds the skeleton of objects or regions in the image. This command is available in the Medical Toolkits.
ClassSmoothEdgesCommand Smoothes the rough edges in the image.
ClassSpatialFilterCommand Imposes a spatial filter on an image. This command is available in the Document/Medical Toolkits.
ClassStatisticsInformationCommand Returns statistical information about the image.
ClassTextureAlphaBlendCommand Combines image data from two images with feathering and constant opacity; by combining the two images with a variable opacity that depends on a fade mask then combine the result with the destination image with a constant opacity.
ClassUnsharpMaskCommand Sharpens the image by applying the unsharp mask.
ClassUserFilterCommand Filters the image based on a user-defined filter / mask. This command is similar to the spatial and binary filter commands.

Enumerations

 EnumerationDescription
EnumerationAntiAliasingCommandType Enumerated values that indicate the type of anti-aliasing filter to use.
EnumerationBinaryFilterCommandPredefined Enumerated values that represent the predefined binary filter to use.
EnumerationCombineCommandFlags Enumeration that indicates the treatment of the source, treatment of the destination, the operation to use when combining the data, and the treatment of the resulting image. The flags apply only to the defined rectangles (not necessarily the whole image).

This enumeration has a FlagsAttribute attribute that allows a bitwise combination of its member values.

EnumerationContourFilterCommandType This enumeration controls the resulting image by telling the method what process to complete before returning.
EnumerationCubismCommandFlags Flags that indicate the background color, cube shape and cube orientation.

This enumeration has a FlagsAttribute attribute that allows a bitwise combination of its member values.

EnumerationCurvePointsType Enumeration that indicates the method to be used to update the curve array.
EnumerationDeinterlaceCommandFlags Flags that indicate how to deinterlace the image and whether to remove odd lines or even lines.

This enumeration has a FlagsAttribute attribute that allows a bitwise combination of its member values.

EnumerationDisplacementCommandFlags Flags that indicate how to handle exposed areas, and the way to use the displacement map image.

This enumeration has a FlagsAttribute attribute that allows a bitwise combination of its member values.
