CurvesCommand Class |
Applies a color curve to an image, similar to the Photoshop Curves method.
The curves are defined by an array of one or more objects.
Namespace: Atalasoft.Imaging.ImageProcessing.Effects
The CurvesCommand type exposes the following members.
| Name | Description | |
|---|---|---|
| CurvesCommand | Creates a new instance of CurvesCommand. | |
| CurvesCommand(PointF, ChannelFlags) | Creates a new instance of CurvesCommand specifying the points of the curve and channels to process.
| |
| CurvesCommand(SerializationInfo, StreamingContext) | Creates a new instance of CurvesCommand from serialization information. |
| Name | Description | |
|---|---|---|
| ApplyToAnyPixelFormat | Reports whether or not this command will be applied to any supplied PixelFormat image (Inherited from ImageCommand.) | |
| AutoThread |
If set to true the IThreadableCommand will automatically parallelize image processing.
| |
| CanApplyToAnyPixelFormat | Returns true if the command can be applied to any PixelFormat. (Inherited from ImageCommand.) | |
| Channels | Gets or sets the channel flags that specify which color channels to process. | |
| InPlaceProcessing | Gets a value indicating if the source image data is processed in-place as opposed to returning a new
image. (Overrides ApplyLutCommandBaseInPlaceProcessing.) | |
| Points | Gets or sets the points that define the curve. | |
| Progress | Gets or sets the ProgressEventHandler delegate which can be used to view or cancel the
progress of the current process. (Inherited from ImageCommand.) | |
| RegionOfInterest | Gets or sets a RegionOfInterest which will only process the indicated region of the image. | |
| SupportedPixelFormats | Returns an array of PixelFormats supported by this command. (Overrides ApplyLutCommandBaseSupportedPixelFormats.) |
| Name | Description | |
|---|---|---|
| AdjustBands |
Sets the image area which will be processed and also defines the bands or chunks of the image of which
each will be sent to a separate thread.
| |
| Apply | Apply the command to the given image. (Inherited from ImageCommand.) | |
| ApplyToImage | Obsolete.
Applies the command to the source AtalaImage.
(Inherited from ImageCommand.) | |
| Clone | Returns a copy of the command. | |
| 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. (Inherited from ImageCommand.) | |
| 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. (Overrides ApplyLutCommandBaseGetObjectData(SerializationInfo, StreamingContext).) | |
| GetType | Gets the Type of the current instance. (Inherited from Object.) | |
| ImageCommandGetObjectData | Aggregates ImageCommand data into the supplied SerializationInfo object. (Inherited from ImageCommand.) | |
| ImplementMe |
Future use.
(Overrides ApplyLutCommandBaseImplementMe.) | |
| IsPixelFormatSupported | Returns a value indicating if the specified pixel format is supported. (Inherited from ImageCommand.) | |
| LLClearChannelLut |
Low-level implementation to clear the channel lookup table.
(Inherited from ApplyLutCommandBase.) | |
| LLGetChannelLut |
Returns the loop-up-table for a single channel.
(Inherited from ApplyLutCommandBase.) | |
| LLSetChannelLut(ChannelFlags, Byte) |
Sets the loop-up-table for a single channel.
(Inherited from ApplyLutCommandBase.) | |
| LLSetChannelLut(ChannelFlags, Int32) |
Low-level implementation of set channel look up table.
(Inherited from ApplyLutCommandBase.) | |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) | |
| PerformActualCommand |
PerformActualCommand does the actual work of the image processing command.
(Overrides ApplyLutCommandBasePerformActualCommand(AtalaImage, AtalaImage, Rectangle, ImageResults).) | |
| PerformSectionCommand |
Performs the command on a specified section of the image.
| |
| 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. (Inherited from ImageCommand.) | |
| 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 ApplyLutCommandBaseVerifyProperties(AtalaImage).) |
