Syntax

Copy

[SerializableAttribute]
public class LensTransform : Transform, 
	ISerializable

<SerializableAttribute>
Public Class LensTransform
	Inherits Transform
	Implements ISerializable

The LensTransform type exposes the following members.

Constructors

	Name	Description
	LensTransform	Creates a new instance of LensTransform.
	LensTransform(Double, Point)	Creates a new instance of LensTransform specifying radius and offset.
	LensTransform(SerializationInfo, StreamingContext)	Creates a new instance of LensTransform from serialization information
	LensTransform(Double, Point, InterpolationMode)	Creates a new instance of LensTransform specifying radius, offset and transformMode.

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.)
	InPlaceProcessing	Gets a value indicating if the source image data is processed in-place as opposed to returning a new image. (Inherited from ImageCommand.)
	Offset	Gets or set the offset position from the center of the image.
	Progress	Gets or sets the ProgressEventHandler delegate which can be used to view or cancel the progress of the current process. (Inherited from ImageCommand.)
	Radius	Gets or sets the maximum distance from the center for this effect.
	SupportedPixelFormats	Returns an array of PixelFormats supported by this command. (Inherited from Transform.)
	TransformMode	The InterpolationMode used with this transform.

Methods

	Name	Description
	AddToChain	Adds this transform to the transforms chain. (Overrides TransformAddToChain(Int32, Int32).)
	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. (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 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	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.)
	SelectCompatibleBackgroundColor	Returns a color value compatible with the image. (Inherited from Transform.)
	SelectPreferredPixelFormat	Chooses a pixel format that is preferred for this command. (Inherited from Transform.)
	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. (Inherited from Transform.)

Remarks

This method requires a continuous tone image. If the source image is not continuous, it will attempt to convert the image into one.

Examples

Lens Example (C#)

Copy

// Load a 24-bit image.
AtalaImage image = new AtalaImage(@"D:\Test Images\1.jpg");

LensTransform cmd = new LensTransform(image.Width / 2, Point.Empty);
AtalaImage result = cmd.Apply(image).Image;

image.Dispose();

Lens Example (Visual Basic)

Copy

' Load a 24-bit image.
Dim image As AtalaImage =  New AtalaImage("D:\Test Images\1.jpg") 

Dim cmd As LensTransform =  New LensTransform(image.Width / 2,PoInteger.Empty) 
Dim result As AtalaImage =  cmd.Apply(image).Image 

image.Dispose()
