Properties

	Name	Description
	Height	Gets or sets the height of the image stored in the double array.
	Max	Gets or sets the maximum double value in the double array associated with the brightest color.

Methods

	Name	Description
	Convert(Byte, UnmanagedImage)	Converts an image from one representation to another. For byte transformations, the Min and Max properties are ignored.
	Convert(Byte, Bitmap)	Converts an image from one representation to another. For byte transformations, the Min and Max properties are ignored.
	Convert(Byte, UnmanagedImage)	Converts an image from one representation to another. For byte transformations, the Min and Max properties are ignored.
	Convert(Byte, Bitmap)	Converts an image from one representation to another. For byte transformations, the Min and Max properties are ignored.
	Convert(Double, UnmanagedImage)	Converts an image from one representation to another.
	Convert(Double, Bitmap)	Converts an image from one representation to another.
	Convert(Double, UnmanagedImage)	Converts an image from one representation to another.
	Convert(Double, Bitmap)	Converts an image from one representation to another.
	Convert(Color, UnmanagedImage)	Converts an image from one representation to another.
	Convert(Color, Bitmap)	Converts an image from one representation to another. For byte transformations, the Min and Max properties are ignored. The resulting image from upon calling this method will always be 32-bit ARGB.
	Convert(Single, UnmanagedImage)	Converts an image from one representation to another.
	Convert(Single, Bitmap)	Converts an image from one representation to another.
	Convert(Single, UnmanagedImage)	Converts an image from one representation to another.
	Convert(Single, Bitmap)	Converts an image from one representation to another.
	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.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Extension Methods

	Name	Description
	HasMethod	Checks whether an object implements a method with the given name. (Defined by ExtensionMethods.)
	IsEqual	Compares two objects for equality, performing an elementwise comparison if the elements are vectors or matrices. (Defined by Matrix.)
	To(Type)	Overloaded. Converts an object into another type, irrespective of whether the conversion can be done at compile time or not. This can be used to convert generic types to numeric types during runtime. (Defined by ExtensionMethods.)
	ToT	Overloaded. Converts an object into another type, irrespective of whether the conversion can be done at compile time or not. This can be used to convert generic types to numeric types during runtime. (Defined by ExtensionMethods.)

Remarks

This class can convert double and float arrays to either Grayscale or color Bitmap images. Color images should be represented as an array of pixel values for the final image. The actual dimensions of the image should be specified in the class constructor.

When this class is converting from byte or Color, the values of the Max and Min properties are ignored and no scaling operation is performed.

Examples

This example converts a single array of double-precision floating- point numbers with values from 0 to 1 into a grayscale image.

Copy

// Create an array representation 
// of a 4x4 image with a inner 2x2
// square drawn in the middle

double[] pixels = 
{
    0, 0, 0, 0, 
    0, 1, 1, 0, 
    0, 1, 1, 0, 
    0, 0, 0, 0, 
};

// Create the converter to create a Bitmap from the array
ArrayToImage conv = new ArrayToImage(width: 4, height: 4);

// Declare an image and store the pixels on it
Bitmap image; conv.Convert(pixels, out image);

// Show the image on screen
image = new ResizeNearestNeighbor(320, 320).Apply(image);
ImageBox.Show(image, PictureBoxSizeMode.Zoom);

The resulting image is shown below.
