Full Changelog: https://github.com/astropy/reproject/compare/v0.9...v0.10.0

0.9 - 2022-09-02

  • Drop support for Python 3.7.
  • Infrastructure and packaging updates.
  • Made many improvements, bug fixes, and significant speed-ups for the adaptive
  • resampling algorithm, reproject_adaptive. These bug fixes may cause
  • changes to the reprojected images, which are typically negligible.
  • Improvements include the addition of a flux-conserving mode, support for a
  • Gaussian filter kernel, a menu of boundary-handling modes, and a
  • center_jacobian flag to trade speed for accuracy with rapidly-varying
  • transformations.
  • Added a roundtrip_coords argument to reproject_adaptive and
  • reproject_interp. By default, all coordinate transformations are run in
  • both directions to handle some situations where they are ambiguous. This can
  • be disabled by setting roundtrip_coords=False which may offer a
  • significant speed increase.

0.8 - 2021-08-11

  • Improve find_optimal_celestial_wcs to accept input data descriptions as
  • just array shapes, not necessarily fully populated arrays. This makes it
  • possible to solve for the optimal WCS for a set of images that couldn't fit
  • into memory all at once, since the actual data aren't needed for optimal WCS
  • determination. [#242]
  • Fix implementation of hdu_weights in reproject_and_coadd. [#249]

0.7.1 - 2020-05-29

  • Fixed compatibility with Astropy 4.1. [#234]
  • Updated minimum requirement for SciPy. [#236]

0.7 - 2020-04-02

  • Made C extension in overlapArea.c thread-safe by removing global
  • variables. [#211]
  • Made it possible to control whether to output debugging information
  • from overlapArea.c by setting DEBUG_OVERLAP_AREA=1 at build-time. [#211]
  • Fix compatibility with astropy v4.0.1. [#227]
  • Disable parallelization by default in reproject_exact - this can be
  • enabled with parallel=True. [#227]
  • Fixed a bug with reproject_exact with parallel=False and
  • return_footprint=False, which caused the footprint to be returned
  • anyway. [#227]
  • The infrastructure of the package has been updated in line with the
  • APE 17 roadmap (https://github.com/astropy/astropy-APEs/blob/main/APE17.rst).
  • The main changes are that the python setup.py test and
  • python setup.py build_docs commands will no longer work. The
  • easiest way to replicate these commands is to install the tox
  • (https://tox.readthedocs.io) package and run tox -e test and
  • tox -e build_docs. It is also possible to run pytest and sphinx
  • directly. [#228]

0.6 - 2019-11-01

  • Added support for using any WCS that conforms to the WCS API described
  • in the Astropy Proposal for Enhancements 14 (APE 14). The
  • independent_celestial_slices= argument to reproject_interp has
  • been deprecated since it is no longer needed, as transformations are
  • automatically done in the most efficient way possible. [#166]
  • Include a warning for high resolution images with reproject_exact,
  • since if the pixels are <0.05", precision issues can occur. [#200]
  • Added a new reproject_and_coadd function for doing mosaicking of
  • individual images, and added section in documentation about mosaicking.
  • [#186]
  • Added a new reproject.adaptive sub-package that implements the DeForest
  • (2004) algorithm for reprojection. [#52]
  • Fixed a bug that caused 'exact' reprojection results to have numerical
  • issues when doing identity transformations. [#190]

0.5.1 - 2019-09-01

  • Fixed a bug that caused 'exact' reprojection to fail if one or more of
  • the WCSes was oriented such that E and W were flipped. [#188]

0.5 - 2019-06-13

  • Improve parse_output_projection to make it so that the output projection
  • can be specified as a filename. [#150]
  • Fixed a bug that caused HEALPix maps in RING order to not be correctly
  • interpreted. [#163]
  • Make it possible to specify the output array for reprojection using the
  • output_array= keyword argument. [#115]

0.4 - 2018-01-29

  • Refactored HEALPix reprojection code to use the astropy-healpix package
  • instead of healpy. [#139]
  • Added the ability to specify an output array in reproject_interp, which
  • permits the use of memory-mapped arrays and therefore provides the capability
  • to handle data cubes much larger than memory [#115]
  • Fix test 32-bit test failures. [#146]
  • Fix an issue with reprojecting images where there are two solutions along
  • the line of sight by forcing round-tripping of coordinate conversions [#129]
  • Explicitly define default HDU as 0 for normal reprojection and 1 for
  • HEALPix reprojection. [#119]
  • Added a function to find the optimal WCS for a set of images. [#136, #137]

0.3.2 - 2017-10-22

  • Fix a regression that caused certain all-sky images (e.g. the Mellinger Milky
  • Way Panorama, http://www.milkywaysky.com) to be reprojected to all NaNs when
  • the output WCS was in Mollweide coordinates. [#124]

0.3.1 - 2016-07-07

  • Include missing license file in tarball.
  • Updated documentation to remove warnings about early versions.

0.3 - 2016-07-06

  • Allow users to pass a field= option to reproject_from_healpix
  • to access different fields in a HEALPIX file. [#86]
  • Significant improvements to performance when the input data is a large
  • memory-mapped array. [#105]
  • Significant refactoring of interpolating reprojection to improve support for
  • n-dimensional arrays, optionally including two celestial axes (in which
  • case the coordinate transformation is taken into account). [#96, #102]

0.2 - 2015-10-29

  • Fixed a bug that caused reprojection by interpolation to be truncated for
  • rectangular output images.

0.1 - 2015-05-08

  • Initial Release.
