1.4 Release Notes For Version 2.3 Nov 2010
Enhancements to CCfits:
• 3 previously protected functions are now made public: Keyword::keytype(), P-
HDU::simple(), and PHDU::extend().
• New function: ExtHDU::isCompressed().
• Uses less memory during the image loading operations for primary and extension
HDUs.
• When the basic version of the FITS constructor is called in Write mode on a
pre-existing file, it will now automatically read ALL of the headers rather than
just the primary. This makes it conform more closely to the Read mode behavior,
and it makes things easier when trying to append new HDUs to files containing
an unknown number of existing HDUs. (See Backwards Compatibility)
Bug Fixes:
• In the 2 FITS class deleteExtension functions, the index numbers of all HDU
objects which follow the deleted are now decremented by one. (See Backwards
Compatibility)
• Fix to the PHDU write functions which take a nullValue argument. Neither could
be instantiated due to an invalid static_cast of pointers.
• Fix needed for the FITS::copy function to allow the Columns in the newly created
HDU to be modifiable.
• The basic version of the FITS constructor, when in Write mode, was ignoring
the user’s readDataFlag and optional primary keys input.
• An error in the (seldom instantiated) Image class assignment operator was preventing
compilation with the nvcc compiler.
• On 64-bit Linux only, a bad cast error is triggered when trying to read an image of
type signed or unsigned long, into a valarray with the opposite signed/unsigned
qualifier.
• All of the FITS::read functions now perform a check to prevent multiple entries
of the same HDU from appearing in the FITS::extension() multimap.
• For case of Columns of type unsigned longs, the object’s lower data limit value
was left unitialized.
