v1.3.1

Release 1.3.1

Major improvements and features added! Check the change-log for details:

• PolygonSet becomes the base class for all polygons, in particular Polygon and Rectangle.
• Added Cell.remove_polygons and Cell.remove_labels functions to allow filtering a cell contents based, for example, on each element's layer.
• Added PolygonSet.scale utility method.
• Added PolygonSet.get_bounding_box utility method.
• Added argument timestamp to Cell.to_gds, GdsLibrary.write_gds and GdsWriter.
• Added unit and precision arguments to GdsLibrary initialization and removed from its write_gds method.
• Changed the meaning of argument unit in GdsLibrary.read_gds.
• Improved slice to avoid errors when slicing in multiple positions at once.
• Improved PolygonSet.fracture to reduce number of function calls.
• Removed incorrect absolute flags for magnification and rotation in CellReference and CellArray.
• Minor bug fixes.
• Documentation fixes.
• Removed deprecated classes and functions.

Minor Release

This release includes minor changes to GdsLibrary.

The newest feature is the integration with Appveyor to build pre-compiled wheels for Windows.

Version 1.2

This release includes one major change that breaks backwards compatibility: addition of a precision parameter to _chop, Polygon.fracture, Polygon.fillet, PolygonSet.fracture, PolygonSet.fillet, and slice.

That is beacuse _chop is now performed in the C extension by the clipper library, which fixed a bug related to issue #23.

Bugfix release

This release fixes a bug introduced in fast_boolean by updating the library to its latest version.

Gdspy license has also been changed to Boost Software License v1.0.

Update (28/04/2017): a precompiled binary for Python 3.4 has been added to the release (must be installed with easy_install). Thanks Jianhua Jiang for the contribution!

Major changes in version 1.1

Gdspy v1.1 brings many changes!

• The most important is the introduction of GdsLibrary, which substitutes and extends GdsImport.
• Development now occurs in python 3, with version 2 being supported via python-future.
• A test suite (still under construction) has been included to help prevent introduction of new bugs.
• Patch 1.1.1 fixes the missing README file in the pypi package.

The documentation has been re-organized and many bugs have been fixed, most notably in functions inside and Cell.copy.

Version 1.0 is here!

Version 1.0 is officially released, including the newest contribution: point-in-polygon logical testing.

Almost version 1.0...

This version introduces new translation and copy features added by John Bell.
A new flag for joining polygons before offsetting them has also been included.

Update Sep. 2: Windows binaries created.

Faster boolean and offset

This release introduces the Clipper library for better performance on boolean and offset operations on polygons.

Compiled Windows binaries are contributed by @johnlb.

Update Aug 26: I'm told the Windows binaries are not working properly. I'll try to update them asap.

First GitHub release

Minor structural changes since version 0.7.

Compiled Windows binaries for Python 3.5 are contributed by @johnlb.

Update Aug 26: I'm told the Windows binaries are not working properly. I'll try to update them asap.
