#include <image.h>

Detailed Description

This provides access to the ImageFormats through a single interface.

A static open routine test all available formats for usability with the given filename.

Notes: Basically an abstract factory + manager or possibly proxy of a sort to instantiate the correct subclass of ImageFormat (abstract parent to instrument-specific and otherwise varying image data file format handling subclasses) and possibly provide a generic interface to the data. In some cases, it appears Image object is bypassed and the programmer goes directly to the ImageFormat object to gain access to the data (see Threshhold plug-in). [2006-01-16 Deborah Lee Soltesz]

void Image::getLL	(	double &	x,
		double &	y
	)

The values of x and y, assumed to be in XY coordinates, are modified to the corresponding latitude and longitude.

Parameters:

`[in,out]`	x	The X coordinate of a point in the image. When the function returns, x holds the longitude corresponding to the input XY location.
`[in,out]`	y	The Y coordinate of a point in the image. When the function returns, y holds the latitude corresponding to the input XY location.
