- Update to version 7.3
* C library
- wcshdo() was writing MJD-OBS twice to the header, and
MJD-BEG not at all.
- In wcshdo(), if MJDREF assumes its default value, just write
MJDREF = 0 (not MJDREFI & MJDREFF), and omit writing DATEREF,
which, with a value of '1858-11-17', looks strange and is
potentially confusing. Reported by Thomas Robitaille.
If the fractional part of MJDREF is zero, then just write the
integer part as MJDREF (i.e. not as MJDREFI & MJDREFF).
- Bug fix in wcsfix() - it was writing error messages that
referred to DATE-REF and MJD-REF rather then DATEREF and
MJDREF. Reported by Mihai Cara.
- Under control of a new flag, WCSHDR_DATEREF, added the option
to wcspih() and wcsbth() to accept DATE-REF, MJD-REF,
MJD-REFI, MJD-REFF, JDREF, JD-REFI, and JD-REFF as synonyms
for the standard keywords, DATEREF, MJDREF, MJDREFI, MJDREFF,
JDREF, JDREFI, and JDREFF. The latter buck the pattern set
by the other date keywords ({DATE,MJD}-{OBS,BEG,AVG,END}),
thereby increasing the potential for confusion and error.
* Fortran wrappers
- As compilers are becoming much stricter (gfortran 10),
modified all Fortran test programs to use the type-specific
equivalents of the various *PUT and *GET routines.
Reported by Ole Streicher.
- For the fitshdr wrappers, added type-specific equivalents
of KEYGET: KEYGTI, KEYGTD, and KEYGTC.
* PGSBOX
- Modified pgtest to use the type-specific equivalents of
WCSPUT.
* User manual
- In the section "WCSLIB Fortran wrappers", promoted use of
the type-specific equivalents of the various *PUT and *GET
routines.
- In the section "FITS-WCS and related software", added ASCL
and ADS codes, where they exist, for all software packages
mentioned.
- Documentation generation moved to doxygen 1.8.18
(was 1.8.17).
- Allow fortran argument mismatches in rank and type to pass the
tests.
- Update to version 7.2:
* C library
- In wcssub(), fixed a bug relating to handling coordinate
lookup tables. Reported by Mihai Cara with fix.
Also increased the number of coordinate axes handled from
10 to 32.
* Installation
- New configure option, --disable-shared, defeats generation
of the sharable library.
Version 7.1:
Changes in the contents of the wcsprm struct necessitated
incrementing the major version number from 6 to 7 (i.e. the
ABI changed).
* C library
- In wcsset(), set wcsprm::mjdref[] to zero if neither it nor
wcsprm::dateref are defined, as per the standard. Reported
by Thomas Robitaille.
wcsset() now also checks that the number of coordinate axes
does not exceed 32.
- In tabs2x(), fixed an out-of-bounds array access produced
by invalid world coordinates. Reported by Mihai Cara and
Michael Seifert.
In tab.c, declare static three helper functions, tabedge(),
tabrow(), and tabvox(), used by tabs2x(). Increased the
number of coordinate axes handled by tabvox() from 16 to
32.
- Extended datfix() to handle MJDREF/DATEREF, overlooked in
the changes in release 6.1. Also fixed the handling of
MJD < 0.
- Support Solar keywords RSUN_REF, DSUN_OBS, CRLN_OBS,
CRLT_OBS, HGLN_OBS, and HGLT_OBS by accomodating them
within an auxiliary struct, auxprm, within the wcsprm
struct. Now filled by the header parsers, wcspih() and
wcsbth() and handled routinely by wcsinit(), wcssub(),
wcscompare(), wcsfree(), wcsprt(), wcsset(), and wcshdo().
Requested by Stuart Mumford (SunPy) with input from Bill
Thompson.
- Bug fix in wcsprintf_set() for resetting the output
disposition.
Reported by Mihai Cara with patch.
- In dis.{h,c}, the DOCORR record is now handled as a
first-class value via disprm::docorr. This required
changing the struct.
- In cel.c, spc.c, wcserr.c, wcsfix.c, wcshdr.c, and
wcsutil.c, quelled compiler warnings from gcc 9.2.0
generated by
-Wmaybe-uninitialized and -Wstringop-truncation (via
-Wall).
Similarly for various programs in the test suite.
- In various functions, quelled warnings from the Microsoft
Visual C++ compiler, mostly relating to pointer arithmetic.
Reported by Michael Seifert.
* Fortran wrappers
- Handled compiler warnings from gcc 9.2.0 generated by
-Wstringop-truncation (via -Wall).
- Minor enhancements to character argument handling,
including, in prjget_(), blank-filling the returned strings
matching PRJ_CODE and PRJ_NAME, and likewise for SPC_TYPE
and SPC_CODE in spcget_().
* Utilities
- In wcsgrid, handled compiler warnings from gcc 9.2.0
generated by -Wstringop-truncation (via -Wall).
* User manual
- In the section on "FITS-WCS and related software", added
mention of the R wrappers (Rwcs). Suggested by Aaron
Robotham.
- Added a new section detailing the limit on the number of
image axes that WCSLIB can handle (currently 32), and how
this could be increased if needed. Prompted by Thomas
Robitaille.
- Augmented the section on the Fortran wrappers, particularly
with respect to character string handling in argument
lists.
- Documentation generation moved to doxygen 1.8.17 (was
1.8.16).
