SetAlphaColorCommand Class |
This command will create an alpha channel for an image based on a color value. If the image already contains alpha information, the color will be blended into it.
Namespace: Atalasoft.Imaging.ImageProcessing.Channels
The SetAlphaColorCommand type exposes the following members.
Name | Description | |
---|---|---|
SetAlphaColorCommand | Creates a new instance of SetAlphaColorCommand. | |
SetAlphaColorCommand(Color) | Creates a new instance of SetAlphaColorCommand specifying
color. | |
SetAlphaColorCommand(Color, Double) | Creates a new instance of SetAlphaColorCommand specifying
color and tolerance. | |
SetAlphaColorCommand(SerializationInfo, StreamingContext) | Creates a new instance of SetAlphaColorCommand from serialization information. | |
SetAlphaColorCommand(Color, Double, AlphaMergeType) | Creates a new instance of SetAlphaColorCommand specifying
color, tolerance, and merge type. | |
SetAlphaColorCommand(Color, Double, AlphaMergeType, Int32, Int32) | Creates a new instance of SetAlphaColorCommand specifying
color, tolerance, merge type, matching alpha, and non-matching alpha. |
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.) | |
Color | Gets or sets the color used to create the alpha channel. | |
InPlaceProcessing | Gets a value indicating if the source image data is processed in-place as opposed to returning a new
image. (Inherited from ImageCommand.) | |
MatchAlpha | Gets or sets the alpha value to use when a match of the color is found. | |
MergeType | Gets or sets the type of merge performed. | |
NonMatchAlpha | Gets or sets the alpha value to use when a match of the color is not found. | |
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.) | |
Tolerance | Gets or sets the tolerance percentage for finding matching colors. |
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.
(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 a SerializationInfo object with information about 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 |
Performs the actual command.
(Overrides ImageCommandPerformActualCommand(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 ImageCommandVerifyProperties(AtalaImage).) |
This method will convert 1-bit, 4-bit and 8-bit grayscale images to 8-bit indexed. 24-bit images will be converted to 32-bit.
