Release v0.5.0

Added

• Argument precision in Cell.write_svg controls the maximum number of digits of coordinates in the SVG
• Function gds_timestamp can be used to query or set the timestamp in a GDSII file
• Better error handling in the C++ API and argument validation for the Python wrapper

Changed

• oas_validate returns None if the file has no checksum information
• Library.write_gds and GdsWriter accept a timestamp setting

Fixed

• Bend calculation for FlexPath correctly accounts for bending angle to make sure the bend fits
• Missing files in the source distribution

Release v0.4.0

Besides the changes indicated in the CHANGELOG (copied below), this releases includes the documentation of the C++ API (all examples, a short introduction, and header files). However, the C++ API is not yet to be considered stable (neither is the Python wrapper, but there shouldn't be many braking changes there).

Added

• Cell.filter to remove elements by layer and data/text type
• Cell.convex_hull and Reference.convex_hull
• FlexPath.path_spines() and RobustPath.path_spines()
• Library.unit and Library.precision
• Shapes can be sorted in Cell.write_svg (sorting works within each cell, references remain on top)

Changed

• Bounding box calculations use convex hull for efficiency
• Bounding box and convex hull calculations cache intermediate results for efficiency

Fixed

• Robustpath.parametric docstring.
• Accept None as a possible value for arguments in several RobustPath methods

Release v0.3.2

Fixed

• Build system fixes for conda recipe

Release v0.3.1

Fixed

• Missing constant definition

Release v0.3.0

0.3.0 - 2021-02-12

Added

• Support for OASIS files
• Repetition property for geometric objects, labels and references
• Library and cells can have properties

Changed

• Use cmake to properly install library
• More efficient bounding box calculation for rotations multiple of 90°
• Labels are now included in bounding box calculations
• Properties can be general or GDSII-specific. Only the latter are stored in gds files.
• Attribute gdsii_path renamed to simple_path in FlexPath and RobustPath.

Release v0.2.0

Added

• How-tos and C++ examples
• Cell.add and Library.add accept iterators
• Repetition class and documentation

Changed

• RawCell doesn't copy the contents of its input file unless needed
• Dependencies for Cell and RawCell are stored in maps, instead of arrays in the C++ API
• The translate method of polygons and paths accept a sequence of 2 coordinates or a complex
• Minor C++ API improvements

Fixed

• Incorrect scaling for FlexPath when scale_width = False
• Typo in default SVG background specification
• Negative path extensions are correctly implemented

Release v0.1.1

Fixed

• Add missing source files to MANIFEST.in
• Remove directory from CMakeLists.txt
• Remove unecessary dependency from conda

Release v0.1.0

Added

• Initial release
