Methods

	Name	Description
	Close	Close decoding of previously opened stream.
	DecodeFrame	Decode specified frame.
	DecodeSingleFrame	Decode first frame of FITS image.
	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.)
	Open	Open specified stream.
	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

The FITS (an acronym derived from "Flexible Image Transport System") format is an astronomical image and table format created and supported by NASA. FITS is the most commonly used in astronomy and is designed specifically for scientific data. Different astronomical organizations keep their images acquired using telescopes and other equipment in FITS format.

Note
The class extracts image frames only from the main data section of FITS file. 2D (single frame) and 3D (series of frames) data structures are supported.

Note
During image reading/parsing, its data are scaled using minimum and maximum values of the source image data. FITS tags are not used for this purpose - data are scaled from the [min, max] range found to the range of supported image format ([0, 255] for 8 bpp grayscale or [0, 65535] for 16 bpp grayscale image).
