/** \defgroup jp2 JP2 - JPEG-2000 JP2 File Format
* \section Description
*
* \par
* ISO/IEC 15444 (2000, 2003)\n
* http://www.jpeg.org/
* \par
* You must link the application with "im_jp2.lib"
* and you must call the function \ref imFormatRegisterJP2 once
* to register the format into the IM core library. \n
* \par
* Access to the JPEG2000 file format uses libJasper version 1.900.1 \n
* http://www.ece.uvic.ca/~mdadams/jasper \n
* Copyright (c) 2001-2006 Michael David Adams. \n
* and GeoJasPer 1.4.0 \n

Data Types: Byte and UShort
Color Spaces: Binary, Gray, RGB, YCbCr, Lab and XYZ
Compressions:
JPEG-2000 - ISO JPEG 2000 [default]
Only one image.
Can have an alpha channel.
Internally the components are always unpacked.
Internally the lines are arranged from top down to bottom.
Handle(1) returns jas_image_t*
Handle(2) returns jas_stream_t*
Attributes:
CompressionRatio IM_FLOAT (1) [write only, example: Ratio=7 just like 7:1]
GeoTIFFBox IM_BYTE (n)
XMLPacket IM_BYTE (n)
Comments:
We read code stream syntax and JP2, but we write always as JP2.
Used definitions EXCLUDE_JPG_SUPPORT,EXCLUDE_MIF_SUPPORT,
EXCLUDE_PNM_SUPPORT,EXCLUDE_RAS_SUPPORT,
EXCLUDE_BMP_SUPPORT,EXCLUDE_PGX_SUPPORT
Changed jas_config.h to match our needs.
New file jas_binfile.c
Changed base/jas_stream.c to export jas_stream_create and jas_stream_initbuf.
Changed jp2/jp2_dec.c and jpc/jpc_cs.c to remove "uint" and "ulong" usage.
The counter is restarted many times, because it has many phases.
