<h1>JP2MrSID --- JPEG2000 via MrSID SDK</h1>

JPEG2000 file format is supported for reading with the MrSID DSDK.  It
is also supported for writing with the MrSID ESDK.<p>

JPEG2000 MrSID support is only available with the version 5.x or newer
DSDK and ESDK.<p>

<h2>Creation Options</h2>

If you have the MrSID ESDK (5.x or newer), it can be used to write JPEG2000
files.  The following creation options are supported.

<ul>
<li> <strong>WORLDFILE=YES</strong>: to write an ESRI world file (with the extension
  .j2w). 
  <p>
<li> <b>COMPRESSION=n</b>: Indicates the desired compression ratio.  Zero indicates
lossless compression.  Twenty would indicate a 20:1 compression ratio (the
image would be compressed to 1/20 its original size).
  <p>

<li> <strong>XMLPROFILE=[path to file]</strong>: Indicates a path to a LizardTech-specific
  XML profile that can be used to set JPEG2000 encoding parameters. They can
  be created
  using
the MrSID ESDK, or with GeoExpress, or by hand using the following example as
a template:
  <p>
<pre>
&lt;?xml version="1.0"?&gt;
&lt;Jp2Profile version="1.0"&gt;
  &lt;Header&gt;
    &lt;name&gt;Default&lt;/name&gt; 
    &lt;description&gt;LizardTech preferred settings (20051216)&lt;/description&gt;
  &lt;/Header&gt;
  &lt;Codestream&gt;
    &lt;layers&gt;
      8
    &lt;/layers&gt;
    &lt;levels&gt;
      99
    &lt;/levels&gt;
    &lt;tileSize&gt;
      0 0
    &lt;/tileSize&gt;
    &lt;progressionOrder&gt;
      RPCL
    &lt;/progressionOrder&gt;
    &lt;codeblockSize&gt;
      64 64
    &lt;/codeblockSize&gt;
    &lt;pltMarkers&gt;
      true
    &lt;/pltMarkers&gt;
    &lt;wavelet97&gt;
      false
    &lt;/wavelet97&gt;
    &lt;precinctSize&gt;
      256 256
    &lt;/precinctSize&gt;
  &lt;/Codestream&gt;
&lt;/Jp2Profile&gt;

</pre>
</ul>
