+/** \defgroup ecw ECW - ECW JPEG 2000
+ * \section Description
+ * 
+ * \par
+ * ECW JPEG 2000 Copyright 1998 Earth Resource Mapping Ltd.
+ * Two formats are supported with this module. The ECW (Enhanced Compression Wavelet) format and the ISO JPEG 2000 format.
+ * \par
+ * Access to the ECW format uses the ECW JPEG 2000 SDK version 3.3. 
+ * Available in Windows, Linux and Solaris Only. But source code is also available. \n
+ * You must link the application with "im_ecw.lib" 
+ * and you must call the function \ref imFormatRegisterECW once 
+ * to register the format into the IM core library. \n
+ * Depends also on the ECW JPEG 2000 SDK libraries (NCSEcw.lib).
+ * \par
+ * When using other JPEG 2000 libraries the first registered library will be used to guess the file format. 
+ * Use the extension *.ecw to shortcut to this implementation of the JPEG 2000 format.
+ * \par
+ * See \ref im_format_ecw.h
+ * \par
+ * \par
+ * http://www.ermapper.com/ecw/ \n
+ * The three types of licenses available for the ECW JPEG 2000 SDK are as follows:
+\verbatim
+   - ECW JPEG 2000 SDK Free Use License Agreement - This license governs the free use of
+     the ECW JPEG 2000 SDK with Unlimited Decompression and Limited Compression (Less
+     than 500MB).
+   - ECW JPEG 2000 SDK Public Use License Agreement - This license governs the use of the
+     ECW SDK with Unlimited Decompression and Unlimited Compression for applications
+     licensed under a GNU General Public style license.
+   - ECW JPEG 2000 SDK Commercial Use License Agreement - This license governs the use

+    Data Types: Byte, UShort, Float
+    Color Spaces: BINARY, GRAY, RGB, YCBCR
+    Compressions:
+      ECW - Enhanced Compression Wavelet
+      JPEG-2000 - ISO JPEG 2000  
+    Only one image.
+    Can have an alpha channel
+    Internally the components are always packed.
+    Lines arranged from top down to bottom.
+    Handle() returns NCSFileView* when reading, NCSEcwCompressClient* when writing.
+ 
+    Attributes:
+      CompressionRatio   IM_FLOAT (1) [example: Ratio=7 just like 7:1]
+      OriginX, OriginY   IM_FLOAT (1)
+      Rotation           IM_FLOAT (1)
+      CellIncrementX, CellIncrementY    IM_FLOAT (1)
+      CellUnits (string)
+      Datum (string)
+      Projection (string)
+      ViewWidth, ViewHeight                    IM_INT (1)    [view zoom]
+      ViewXmin, ViewYmin, ViewXmax, ViewYmax   IM_INT (1)    [view limits]
+      MultiBandCount IM_USHORT (1)    [Number of bands in a multiband gray image.]
+      MultiBandSelect IM_USHORT (1)   [Band number to read one band of a multiband gray image. Must be set before reading image info.]
+
+    Comments:
+      Only read support is implemented.
+      To read a region of the image you must set the View* attributes before reading the image data.
+      After reading a partial image the width and height returned in ReadImageInfo is the view size.
+      The view limits define the region to be readed. 
+      The view size is the actual size of the image, so the result can be zoomed.
