changes:
-API additions
-hdp and hrepack utilities can now display more compression information
-build system updates
-bugfixes
pkgsrc notes:
-we build shared libraries now although it is officially unsupported
if Fortran is enabled (works for me)
-The 24-bit-jpeg selftest fails. It also failed with the previous
version. (perhaps jpeg-7 related?) The test contains too much magic
to tell what happens.
Configuration
* By default HDF4 libraries and utilities are installed under
<source_dir>/NewHDF
* Windows configuration, build and testing procedures have been changed.
Please see INSTALL_WINDOWS.txt file for more information
Library
* New API SDidtype was added to the library (bug #766)
* HCgetcompress renamed to HCPgetcompress
* New API HCget_config_info added
* The default chunk cache size was changed for 2D and higher
chunks
* Pablo instumentation was removed
Utilities
* hdiff and hrepack are supported on Windows.
* Substantial performance improvements in hdiff and hrepack
Support for new platforms and compilers
* Fortran IBM xlf v 8.1 and Absoft f95 version 8.2 compilers
are supported on Mac OSX.
* Absoft Fortran compiler f95 version 9.0 is supported on Linux 2.4
* PGI C and Fortran compilers are supported on Linux 2.4
* Intel C and Fortran compilers are supported on Linux 2.4
* Cray TS IEEE is supported.
Bugs fixed since HDF4.2r0
* VERY IMPORTANT:
Data compressed with SZIP may be corrupted; fixed. For more
information see "HDF4.2r1 SZIP Release Notes" available at
http://hdf.ncsa.uiuc.edu/doc_resource/SZIP/SZIP_HDF4_2r1.pdf
* Fortran couldn't read names with spaces when NetCDF interfaces
were used; fixed
* Library failed to compile in presence of the NetCDF library; fixed
* h4fc couldn't create object files; fixed
* When rank of SDS is 0, some SD APIs give segmentation fault (bug 1045);
fixed
* Some GR images with special elements are read in as duplicate
(bug 814); fixed
* Many bugs fixed in hdiff and hrepack utilities
New Features and Changes:
========================
o The following Vdata routines were added:
VSsetblocksize/vsfsetblsz -- sets the block size of the
linked-block element.
VSsetnumblocks/vsfsetnmbl -- sets the number of blocks for
a linked-block element.
VSgetblockinfo/vsfgetblinfo -- retrieves the block size and the number
of blocks of a linked-block element.
o Two routines were added to get compression information for the SD and
GR interfaces, including chunked elements: SDgetcompress/sfgcompress
and GRgetcompress/mggcompress.
Note:
- For a JPEG image, GRgetcompress only returns the compression type, not
the compression information (i.e, quantity and force_baseline). This
information is not currently retrievable.
- Getting compression type for JPEG chunked images is not working yet.
o "hdp dumpgr" has a new option, -pd, to print palette data only. Also,
whenever option -p or -pd is given, only palettes are printed, and no
images or file attributes.
o A new FORTRAN function, heprntf (HEprint), was added. It takes two
arguments: file name and level. If the file name string has 0 length,
then error messages will be printed to standard output.
o A memory leak in the netCDF portion of the HDF/mfhdf distribution
was fixed.
o The "#define NULL" was removed since ANSI C compilers are required to
define NULL.
o When using "hdp dumpgr", data was being printed in the range of 0-250
when it should have been between 0-168. This problem is now fixed.
Fortran, libf2c is static, etc. Fixed "hdfi.h" to work with any
architecture supported by NetBSD. Use "xdrposix.c" instead of
"xdrstdio.c" since the latter seems to be missing some functions.
Fixed "initialization from incompatible pointer type" warnings.
General improvements to Makefiles. Should build/work on any NetBSD
system now.
sensible value if a dependency is not yet installed. Problem noted by
Matthias Drochner with fix by Alistair Crooks.
Fixed `ncgen' to generate files which #include "netcdf_hdf.h" and
"netcdf_hdf.inc" thus allowing the HDF and netCDF packages to coexist.
Added test target in package Makefile for compiling and running the tests
for the libraries and the `ncdump' program.
HDF is a multi-object file format that facilitates the transfer of
various types of scientific data between machines and operating
systems. HDF allows self-definitions of data content and easy
extensibility for future enhancements or compatibility with other
standard formats. HDF includes Fortran and C calling interfaces, and
utilities to prepare raw image of data files or for use with other
NCSA software. The HDF library contains interfaces for storing and
retrieving compressed or uncompressed 8-bit and 24-bit raster images
with palettes, n-Dimensional scientific datasets and binary tables.
An interface is also included that allows arbitray grouping of other
HDF objects.
