Guidelines for Derived SID Files
The LizardTech MrSID file format is the Digital Library Center's defacto standard for single zoomable graphics and large-format images. To ensure that SID files are compatible with the XPAT Image Class middleware used by the Florida Center for Library Automation to serve SID images, the following parameters are observed.

  1. Select the files to be compressed by MrSID.
  2. For each file, apply the following:

    Target Compression = 100:1
    Zoom Levels (as follows)
    Maximum image dimension is
    >0 and <= 800
    ... level = 2
    >800 and <= 1600
    ... level = 3
    >1600 and <= 3200
    ... level = 4
    >3200
    ... level = 5
    Target Thumbnail = 500
    Block Size = 512  
       

  3. Send output SID files to the location of the source file.
