VERSION History
|
||||
|
||||
1.6.0 (June 2012)
|
||||
- Fixed behavior of the "rename" function on Windows platforms so that
|
||||
it will clobber/delete an existing file before renaming a file to
|
||||
that name (the rename command behaves differently on POSIX and non-POSIX
|
||||
environments).
|
||||
|
||||
1.6.0 (February 2011)
|
||||
- Added full support for compressing and uncompressing FITS binary tables
|
||||
using a newly proposed format convention. This is intended only for
|
||||
further feasibility studies, and is not recommended for use with publicly
|
||||
distributed FITS files.
|
||||
- Use the minimum of the MAD 2nd, 3rd, and 5th order values as a more
|
||||
conservative extimate of the noise when quantizing floating point images.
|
||||
- Enhanced the tile compression routines so that a tile that contains all
|
||||
NaN pixel values will be compressed.
|
||||
- When uncompressing an image that was originally in a FITS primary array,
|
||||
funpack will also append any new keywords that were written into the
|
||||
primary array of the compressed FITS file after the file was compressed.
|
||||
- Added support for the GZIP_2 algorithm, which shuffles the bytes in the
|
||||
pixel values prior to compressing them with gzip.
|
||||
1.5.1 (December 2010) Added prototype, mainly hidden, support for compressing
|
||||
binary tables.
|
||||
1.5.0 (August 2010) Added the -i2f option to lossy compress integer images.
|
||||
1.4.0 (Jan 2010) Reduced the default value for the q floating point image
|
||||
quantization parameter from 16 to 4. This results in about 50% better
|
||||
compression (from about 4.6x to 6.4) with no lost of significant information
|
||||
(with the new subtractive dithering enhancement). Replaced the code for
|
||||
generating temporary filenames to make the code more portable (to Windows).
|
||||
Replaced calls to the unix 'access' and 'stat' functions with more portable
|
||||
code. When unpacking a file, write it first to a temporary file, then
|
||||
rename it when finished, so that other tasks cannot try to read the file
|
||||
before it is complete.
|
||||
1.3.0 (Oct 2009) added randomization to the dithering pattern so that
|
||||
the same pattern is not used for every image; also added an option
|
||||
for losslessly compressing floating point images with GZIP for test
|
||||
purposes (not recommended for general use). Also added support for
|
||||
reading the input FITS file from the stdin file streams.
|
||||
1.2.0 (Sept 2009) added subtractive dithering feature (in CFITSIO) when
|
||||
quantizing floating point images; When packing an IRAF .imh + .pix image,
|
||||
the file name is changed to FILE.fits.fz, and if the original file is
|
||||
deleted, then both the .imh and .pix files are deleted.
|
||||
1.1.4 (May 2009) added -E option to funpack to unpack a list of HDUs
|
||||
1.1.3 (March 2009) minor modifications to the content and format of the -T report
|
||||
1.1.2 (September 2008)
