Fitsio

----------------------------------

New tag so that pypi will accept the updated version

----------------------------------

New Features

- header_start, data_start, data_end now available in the
info dictionary, as well as the new get_offsets() method
to access these in a new dict.
(thanks Dimitri Muna for the initial version of this)

Bug Fixes

- Fix bug when writing new COMMENT fields (thanks Alex Drlica-Wagner for
initial fix)
- deal correctly with aligned data in some scenarios
(thanks Ole Streicher)
- use correct data type long for tile_dims_fits in
the set_compression C code. This avoids a crash
on 32 but systems. (thanks Ole Streicher)
- use correct data type npy_int64 for pointer in
get_long_slices (this function is not not correctly
named). Avoids crash on some 32 bit systems.
(thanks Ole Streicher)
- use correct data type npy_int64 for pointer in
PyFITSObject_create_image_hdu, rather than npy_intp.
(thanks Ole Streicher)

----------------------------------

New Features

- added read_scamp_head function to read the .head files output
by SCAMP and return a FITSHDR object
- reserved header space when creating image and table extensions
and a header is being written. This can improve performance
substantially, especially on distributed file systems.
- When possible write image data at HDU creation. This can
be a big performance improvement, especially on distributed file
systems.
- Support for reading bzipped FITS files. (Dustin Lang)

- Added option to use the system CFITSIO instead of the bundled one,
by sending --use-system-fitsio. Strongly recommend only use cfitsio
that are as new as the bundled one. Also note the bundled cfitsio
sometimes contains patches that are not yet upstream in an
official cfitsio release
- proper support for reading unsigned images compressed with PLIO.
This is a patch directly on the cfitsio code base. The same
code is in the upstream, but not yet released.
- New method reshape(dims) for images
- When writing into an existing image HDU, and larger dimensions
are required, the image is automatically expanded.

Bug Fixes

- Fixed broken boolean fields in new versions of numpy (rainwoodman) Fixed
- bug when image was None (for creating empty first HDU) removed -iarch in
- setup.py for mac OS X. This should
work for versions Mavericks and Snow Leapard (Christopher Bonnett)
- Reading a single string column was failing in some cases, this
has been fixed
- When creating a TableColumnSubset using [cols], the existence
of the columns is checked immediately, rather than waiting for the
check in the read()
- make sure to convert correct endianness when writing during image HDU
creation
- Corrected the repr for single column subsets
- only clean bzero,bscale,bunit from headers for TableHDU

Dev features

- added travis ci

----------------------------------

New Features

- python 3 compatibility
- Adding a new HDU is now near constant time
- Can now create an empty image extension using create_image_hdu
and sending the dims= and dtype= keywords
- Can now write into a sub-section of an existing image using the
start= keyword.
- Can now use a scalar slice for reading images, e.g.
hdu[row1:row2, col]
although this still currently retains the extra dimension
- Use warnings instead of printing to stdout
- IOError is now used to indicate a number of errors that
were previously ValueError

--------------

New Features

- use cfitsio 3370 to support new tile compression features
- FITSRecord class to encapsulate all the ways one can represent header
records. This is now used internally in the FITSHDR class instead of raw
dicts, but as FITSRecord inherits from dict this should be transparent.
- FITSCard class; inherits from FITSRecord and is a special case for header
card strings
- One can directly add a fits header card string to the FITSHDR object
using add_record

Bug Fixes

- use literal_eval instead of eval for evaluating header values (D. Lang)
- If input to write_keys is a FITSHDR, just use it instead of creating a
new FITSHDR object. (D. Lang)
- update existing keys when adding records to FITSHDR, except for
comment and history fields.
- fixed bug with empty string in header card
- deal with cfitsio treating first 4 comments specially

--------------------------------

Note the version 0.9.4 was skipped because some people had been using the
master branch in production, which had version 0.9.4 set. This will allow
automatic version detection to work. In the future master will not have
the next version set until release.

New Features

- Re-factored code to use sub-classes for each HDU type. These are called
ImageHDU, TableHDU, and AsciiTableHDU.
- Write and read 32-bit and 64-bit complex table columns
- Write and read boolean table columns (contributed by Dustin Lang)
- Specify tile dimensions for compressed images.
- write_comment and write_history methods added.
- is_compressed() for image HDUs, True if tile compressed.
- added `**keys` to the image hdu reading routines to provide a more uniform
interface for all hdu types

Bug Fixes

- Correct appending to COMMENT and HISTORY fields when writing a full
header object.
- Correct conversion of boolean keywords, writing and reading.
- Strip out compression related reserved keywords when writing a
user-provided header.
- Simplified reading string columns in ascii tables so that certain
incorrectly formatted tables from CASUTools are now read accurately.
The change was minimal and did not affect reading well formatted tables,
so seemed worth it.
- Support non-standard TSHORT and TFLOAT columns in ascii tables as
generated by CASUTools. They are non-standard but supporting them
does not seem to break anything (pulled from Simon Walker).

All changes E. Sheldon except where noted.
