     Some file formats do not describe some aspects of the data	they contain.
     For example, an SGI image file does not describe the pixel	aspect for the

     pair of interlaced	video fields.  In cases	like these, the	values of the
     corresponding track parameters are	not displayed.

     dminfo uses the SGI Audio File, Compression, ImageVision, and Movie
     Libraries to access digital media data.

     Many of the image file formats are	supported through the San Diego
     Supercomputer Center's image library (libim, libsdsc).  This library is
     available from anonymous ftp at sdsc.edu in the
     /pub/sdsc/graphics/imtools/ directory.  For more information, contact
