Standard Image Metadata Derivation

The conversion between the native image metadata format and the standard image metadata format is based on the following mapping:
Standard Metadata Attribute        JP2 Box Element
---------------------------        ---------------
/Chroma
    /ColorSpaceType
	@name			   if UnknownColorSpace in header box is 0
				   then if EnumeratedColorSpace in
					color specification box is 16 --> RGB
				        if EnumeratedColorSpace in
                                        color specification box is 17 -->GRAY
    /NumChannels
	@value			   if palette box exists
					the component number in palette box 
				   else
					the component number in header box
    /Palette			   if palette box exits
	/PaletteEntry
	    @index		   
	    @red		   lut[index][0]
	    @green		   lut[index][1]
	    @blue		   lut[index][2]
	    @alpha 		   lut[index][3] if the component number is 4

/Compression
    @value			   "JPEG2000"

/Data
    /SampleFormat
	@value			   if the palette box exists, -->"Index"
				   else if bit depth in header box or 
					bits per component box has the sign bit
					     --> "SignedIntegral"
					else --> "UnsignedIntegral"
    /BitsPerSample
	@value			   derive from the bit depth of header box
				   or bits per component box
    /PlanarConfiguration
	@value			   --> "TileInterleaved"

/Dimension
    /PixelAspectRatio
	@value			   the ratio of the horizontal and vertical
				   resolution in the capture resolution box
    /HorizontalPhysicalPixelSpacing
	@value			   derived from the horizontal resolution
				   (in pixel-per-meter) in the capture 
				   resolution box
    /VerticalPhysicalPixelSpacing 
        @value                     derived from the vertical resolution         
                                   (in pixel-per-meter) in the capture i
				   resolution box
/Transparency
    /Alpha
	@value			   --> "none" if no channel definition box or
					no alpha channel is defined in channel
					definition box
				   --> "nonpremultiplied" if no premultiplied
					channel is defined in the channel 
					definition box
				   --> "premultiplied" if any premultiplied
					channel(s) defined in the channel 
					definition box
/Text
    /TextEntry
	@value			   The content of any XML box; each XML box
				   defines a TextEntry
