JP2MrSID --- JPEG2000 via MrSID SDK

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

Creation Options

• WORLDFILE=YES: to write an ESRI world file (with the extension .j2w).

• COMPRESSION=n: 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).

• XMLPROFILE=[path to file]: 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:

  <?xml version="1.0"?>
  <Jp2Profile version="1.0">
    <Header>
      <name>Default</name>
