public class ReduceColorsCommand : ImageCommand, 
	ISerializable

<SerializableAttribute>
Public Class ReduceColorsCommand

The ReduceColorsCommand type exposes the following members.

Constructors

	Name	Description
	ReduceColorsCommand	Creates a new instance of ReduceColorsCommand.
	ReduceColorsCommand(Int32)	Creates a new instance of ReduceColorsCommand specifying colors.
	ReduceColorsCommand(SerializationInfo, StreamingContext)	Creates a new instance of ReduceColorsCommand from serialization information.
	ReduceColorsCommand(Int32, DitheringMode, Int32)	Creates a new instance of ReduceColorsCommand specifying colors, ditherMode, and ditherMaxError.

Properties

	Name	Description
	ApplyToAnyPixelFormat	Reports whether or not this command will be applied to any supplied PixelFormat image (Inherited from ImageCommand.)
	CanApplyToAnyPixelFormat	Returns true if the command can be applied to any PixelFormat. (Inherited from ImageCommand.)
	Colors	Gets or sets the number of colors you want the resulting image to contain.
	DitherMaxError	Gets or sets the maximum error value that can be carried between pixels.
	DitherMode	Gets or sets the type of DitheringMode to perform.
	InPlaceProcessing	Gets a value indicating if the source image data is processed in-place as opposed to returning a new image. (Inherited from ImageCommand.)
	Progress	Gets or sets the ProgressEventHandler delegate which can be used to view or cancel the progress of the current process. (Inherited from ImageCommand.)
	SupportedPixelFormats	Returns an array of PixelFormats supported by this command. (Overrides ImageCommandSupportedPixelFormats.)

Methods

	Name	Description
	Apply	Apply the command to the given image. (Inherited from ImageCommand.)
	ApplyToImage	Obsolete. Applies the command to the source AtalaImage. (Inherited from ImageCommand.)
	ConstructChangedSourceImage	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.)
	ConstructFinalImage	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).)
	ConstructImageResults	Constructs the results object for this command. (Inherited from ImageCommand.)
	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.)
	GetChangedPixelFormat	This method is called to change the pixel format of the source image. (Inherited from ImageCommand.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetObjectData	Fills the SerializationInfo object with information for this command.
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	ImageCommandGetObjectData	Aggregates ImageCommand data into the supplied SerializationInfo object. (Inherited from ImageCommand.)
	IsPixelFormatSupported	Returns a value indicating if the specified pixel format is supported. (Inherited from ImageCommand.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	PerformActualCommand	PerformActualCommand does the actual work of the image processing command. (Overrides ImageCommandPerformActualCommand(AtalaImage, AtalaImage, Rectangle, ImageResults).)
	SelectBestAlternatePixelFormat	Choose the best pixel format to use for this command when the supplied source image's pixel format is unacceptable. (Inherited from ImageCommand.)
	SelectPreferredPixelFormat	Chooses a pixel format that is preferred for this command. (Overrides ImageCommandSelectPreferredPixelFormat(AtalaImage, PixelFormat, PixelFormat).)
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	VerifyImage	Verify the integrity of an AtalaImage. (Inherited from ImageCommand.)
	VerifyProperties	Verify the integrity of properties in the command before processing an image. (Overrides ImageCommandVerifyProperties(AtalaImage).)

Remarks

This method requires a 24 or 32 bit image. If the source image is of a different format, it will raise the ChangePixelFormat event and convert the image to a compatible format.
