Change history

PyEPR 0.7.1 (19/08/2013)

• fixed potential issues with conversion from python strings to char*
• new snapshot of the EPR C API sources (2.3dev):
  • the size of the record tables has been fixed
  • the EPR_NUM_PRODUCT_TABLES has been fixed
  • fixed a missing prototype
  • several GCC warnings has been silenced
  • additional checks on return codes
  • now and error is raised when an invalid flag name is used
• better factorization of Python 3 specific code
• use the CLOUD flag instead of BRIGHT in unit tests
• added function/method signature to all doc-strings for better interactive help
• several improvements to the documentation:
  • updated the README.txt file to mention EPR C API sourced inclusion in the PyEPR 0.7 (and lates) source tar-ball
  • small fix in the installation instructions: the pip tool does not have a “–prefix” parameter
  • always use the python3 syntax for the print function in all examples in the documentation
  • links to older (and dev) versions of the documentation have been added in the man page of the HTML doc
  • removed date form the doc meta-data. The documentation build date is reported in the front page of the LaTeX (PDF) doc and, starting from this release, in the footer of the HTML doc.
  • the Ohloh widget has been added in the sidebar of the HTML doc
  • improved the regexp for detecting the SW version in the :file`setup.py` script
  • formatting

PyEPR 0.7 (04/08/2013)

• more detailed error messages in case of open failures

• new sphinx theme for the HTML documentation

• Travis-CI has been set-up for the project

• now the source tar-ball also includes a copy of the EPR C API sources so that no external C library is required to build PyEPR.

  This features also makes it easier to install PyEPR using pip.

  The user can still guild PyEPR against a system version of the ERP-API library simply using the --epr-api-src option of the setup.py script with “None”” as value.

  The ERP C API included in the source tar-ball is version 2.3dev-pyepr062, a development and patched version that allows the following enhancements.

  • support for ERS products in ENVISAT format
  • support for ASAR products generated with the new ASAR SW version 6.02 (ref. doc. PO-RS-MDA-GS-2009_4/C
  • fix incorrect reading of “incident_angle” bands (closes gh-6). The issue is in the EPR C API.

PyEPR 0.6.1 (26/04/2012)

• fix compatibility with cython 0.16
• added a new option to the setup script (--epr-api-src) to build PyEPR using the EPR-API C sources

PyEPR 0.6 (12/08/2011)

• full support for Python 3
• improved code highligh in the documentation
• depend from cython >= 0.13 instead of cython >= 0.14.1. Cythonizing epr.pyx with Python 3 requires cython >= 0.15

PyEPR 0.5 (25/04/2011)

• stop using PyFile_AsFile() that is no more available in Python 3
• now documentation uses intersphinx capabilities
• code examples added to documentation
• tutorials added to documentation
• the LICENSE.txt file is now included in the source distribution
• the cython construct with nogil is now used instead of calling Py_BEGIN_ALLOW_THREADS() and Py_END_ALLOW_THREADS() directly
• dropped old versions of cython; now cython 0.14.1 or newer is required
• suppressed several constness related warnings

PyEPR 0.4 (10/04/2011)

• fixed a bug in the epr.Product.__str__(), Dataset.__str__() and erp.Band.__repr__() methods (bad formatting)
• fixed epr.Field.get_elems() method for char and uchar data types
• implemented epr.Product.read_bitmask_raster(), now the epr.Product API is complete
• fixed segfault in epr.Field.get_unit() method when the field has no unit
• a smaller dataset is now used for unit tests
• a new tutorial section has been added to the user documentation

PyEPR 0.3 (01/04/2011)

• version string of the EPR C API is now exposed as module attribute epr.EPR_C_API_VERSION
• implemented __repr__, __str__, __eq__, __ne__ and __iter__ special methods
• added utility methods (not included in the C API) like:
  • epr.Record.get_field_names()
  • epr.Record.fields()
  • epr.Dataset.records()
  • epr.Product.get_dataset_names()
  • epr.Product.get_band_names()
  • epr.Product.datasets()
  • epr.Product.bands()
• fixed a logic error that caused empty messages in custom EPR exceptions

PyEPR 0.2 (20/03/2011)

• sphinx documentation added
• added docstrings to all method and classes
• renamed some method and parameter in order to avoid redundancies and have a more pythonic API
• in case of null pointers a epr.EPRValueError is raised
• improved C library shutdown management
• introduced some utility methods to epr.Product and epr.Record classes

PyEPR 0.1 (09/03/2011)
