This release of NCSA Mosaic includes native support for browsing
data files in NCSA HDF format.  For more information on HDF, see
ftp.ncsa.uiuc.edu in /HDF or URL:
        
  http://www.ncsa.uiuc.edu/SDG/Software/HDF/HDFIntro.html

If you compile Mosaic from source, link to HDF 3.3r1 (or the most
recently announced HDF 3.3 revision at the time you compile) from
ftp.ncsa.uiuc.edu in /HDF.  Note that HDF 3.3 supports UCAR's netCDF
data format transparently.

There are some new X resources for Mosaic 2.0 that customize the HDF
browsing capabilities:

hdfMaxImageDimension
  Maximum size for an inlined HDF image.  If an image dimension
  is larger than this, the image will be scaled down for display
  and that fact (and the original dimensions) will be noted in the
  text description next to the inlined image.  Default 400.
hdfMaxDisplayedDatasets
  Maximum number of datasets that will be displayed on a toplevel
  page (additional datasets will be placed on another page).
  Default 15.
hdfMaxDisplayedAttributes
  Maximum number of attributes that will be displayed on a toplevel
  page (additional attributes will be placed on another page).
  Default 10.
hdfPowerUser
  If true, less verbose text will be generated.  Default false.

For more information on the HDF browsing support in general, see:

  http://www.ncsa.uiuc.edu/SDG/Software/Mosaic/Docs/hdf-browsing.html

Some example HDF files suitable for browsing are referenced
near the end of the Mosaic demo document.
