Properties
  NameDescription
Public propertyApplyToAnyPixelFormat
Reports whether or not this command will be applied to any supplied PixelFormat image
(Inherited from ImageCommand.)
Public propertyCanApplyToAnyPixelFormat
Returns true if the command can be applied to any PixelFormat.
(Inherited from ImageCommand.)
Public propertyGamma
Gets or sets the gamma adjustment to apply when running the filter. Default GammaColor.Default.
Public propertyHighlightColor
Gets or sets the white point in the image used as an input clipping point. Default Color.White.
Public propertyInPlaceProcessing
Indicates whether or not the command will operate on the source image alone.
(Overrides ApplyLutCommandBaseInPlaceProcessing.)
Public propertyMidtoneColor
Gets or sets the gray point in the image used as a gamma adjustment. Gamma is used by default.
Public propertyOutputRangeHigh
Gets or sets the light color value to stretch the histogram to. Default Color.Black.
Public propertyOutputRangeLow
Gets or sets the dark color value to stretch the histogram to. Default Color.Black.
Public propertyProgress
Gets or sets the ProgressEventHandler delegate which can be used to view or cancel the progress of the current process.
(Inherited from ImageCommand.)
Public propertyRegionOfInterest

Gets or sets a RegionOfInterest which will only process the indicated region of the image.

(Inherited from ImageRegionCommand.)
Public propertyShadowColor
Gets or sets the black point in the image used as an input clipping point. Default Color.Black.
Public propertySupportedPixelFormats
Returns an array of PixelFormats supported by this command.
(Overrides ApplyLutCommandBaseSupportedPixelFormats.)

Methods
  NameDescription
Public methodApply
Apply the command to the given image.
(Inherited from ImageCommand.)
Public methodApplyToImage Obsolete.
Applies the command to the source AtalaImage.
(Inherited from ImageCommand.)
Protected methodConstructChangedSourceImage
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.)
Protected methodConstructFinalImage
Called by the default implementation of Apply, ConstructFinalImage constructs the image that will be used as the destination image for the command.
(Inherited from ImageCommand.)
Protected methodConstructImageResults
Constructs the results object for this command.
(Inherited from ImageCommand.)
Public methodEquals
Determines whether the specified object is equal to the current object.
(Inherited from Object.)
Protected methodFinalize
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.
(Inherited from Object.)
Protected methodGetChangedPixelFormat
This method is called to change the pixel format of the source image.
(Inherited from ImageCommand.)
Public methodGetHashCode
Serves as the default hash function.
(Inherited from Object.)
Public methodStatic memberGetHighThreshold
Calculates the high threshold value.
Public methodStatic memberGetLowThreshold
Calculates the low threshold value.
Public methodGetObjectData

Populates a SerializationInfo with the data needed to serialize the target object.

(Overrides ApplyLutCommandBaseGetObjectData(SerializationInfo, StreamingContext).)
Public methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
Protected methodImageCommandGetObjectData
Aggregates ImageCommand data into the supplied SerializationInfo object.
(Inherited from ImageCommand.)
Protected methodImplementMe
Future use.
(Overrides ApplyLutCommandBaseImplementMe.)
Public methodIsPixelFormatSupported
Returns a value indicating if the specified pixel format is supported.
(Inherited from ImageCommand.)
Protected methodLLClearChannelLut
Low-level implementation to clear the channel lookup table.
(Inherited from ApplyLutCommandBase.)
Protected methodLLGetChannelLut
Returns the loop-up-table for a single channel.
(Inherited from ApplyLutCommandBase.)
Protected methodLLSetChannelLut(ChannelFlags, Byte)
Sets the loop-up-table for a single channel.
(Inherited from ApplyLutCommandBase.)
Protected methodLLSetChannelLut(ChannelFlags, Int32)
Low-level implementation of set channel look up table.
(Inherited from ApplyLutCommandBase.)
Protected methodMemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)
Protected methodPerformActualCommand
PerformActualCommand does the actual work of the image processing command.
(Overrides ApplyLutCommandBasePerformActualCommand(AtalaImage, AtalaImage, Rectangle, ImageResults).)
Protected methodSelectBestAlternatePixelFormat
Choose the best pixel format to use for this command when the supplied source image's pixel format is unacceptable.
(Inherited from ImageCommand.)
Protected methodSelectPreferredPixelFormat
Chooses a pixel format that is preferred for this command.
(Inherited from ImageCommand.)
Public methodToString
Returns a string that represents the current object.
(Inherited from Object.)
Protected methodVerifyImage
Verify the integrity of an AtalaImage.
(Inherited from ImageCommand.)
Protected methodVerifyProperties
Verify the integrity of properties in the command before processing an image.
(Overrides ApplyLutCommandBaseVerifyProperties(AtalaImage).)

Remarks
The shadow, midtone, and highlights are often manually determined from an "eyedropper" tool.
