+ * \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.
