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
@since 1.0
