v0.9.3

Bump version: 0.9.2 → 0.9.3

Release v0.9.1

Bug fix release with several improvements:

• Reading polygons with extremelly large number of vertices
• Integer overflow in boolean operations
• GdsWriter C++ API fix
• Properly read zlib path from environment during build
• Ensure polygons are closed when laoding GDSII files
• Reference counting in Reference.apply_repetition and Cell.flatten

Thanks to all who contributed to the PRs and fixes in this release!

Release v0.9.0

Fixed

• Bug when saving OASIS files with missing references.

Added

• Reference.get_polygons, Reference.get_paths, Reference.get_labels
• Library.rename_cell
• Library::rename_cell and Library::replace_cell in the C++ API

Changed

• Cell.filter arguments modified to match read_gds.
• Changed default tolerance for read_gds and read_oas to be the library's rounding size.
• Reference::polygons renamed to Reference::get_polygons in the C++ API.
• Reference::flexpaths renamed to Reference::get_flexpaths in the C++ API.
• Reference::robustpaths renamed to Reference::get_robustpaths in the C++ API.
• Reference::labels renamed to Reference::get_labels in the C++ API.
• Removed magnification argument from Reference::init and Label::init in the C++ API.

Release v0.8.3

Bug fix release:

• References from raw cells are kept from garbage collection while in use
• Allow assigning to Reference.x_reflection from Python
• Errors in detection of arrays when exporting GDSII files

Release v0.8.2

Minor bugfix release. There are minor changes in the cmake script to aid building in Windows (thanks to @massarom)

Fixed

• Cell.get_paths not returning all FlexPaths when RobustPaths were present in the cell (thanks @jatoben)
• Reference array is no longer transformed into multiple references when element displacement is zero
• Memory leaks in the python wrapper (thanks @jatoben)

Changed

• Set separation instead of offset in FlexPath::init and RobustPath::init

Release v0.8.1

Fixed

• Missing flag in OASIS bounding box property
• Bug in bounding box when using explicit repetitions
• Segfault when loading GDSII files with missing cells

Changed

• GdsWriter C++ API
• Safer initializers C++ API

Release v0.8.0

Added

• Cell.get_polygons, Cell.get_paths, and Cell.get_labels return a copy of a cell’s polygons, paths or labels, including references, with the possibility of filtering by layer and type
• Library.layers_and_datatypes and Library.layers_and_texttypes return tuples with the layer and data/text types found in the library.
• gdstk.gds_info provide information about a GDSII file without fully loading it
• Several FlexPath and RobustPath attributes.

Fixed

• Label transforms in SVG output
• Label styling in SVG output
• Default label magnification when loading a GDSII file
• Bugs when loading some OASIS files
• Bug in OASIS output for some Manhattan geometry.
• Bug fix in Map::del
• Bounding box calculations take all repetitions into account
• Memory leaks

Changed

• Removed LAPACK dependency
• The implementation of layer and data/text type for shapes and labels use the type Tag in the C++ API
• Style arguments renamed in Cell.write_svg

Release v0.7.0

This version includes some breaking changes to the API. Most notably, the change in the gdstk.inside function and the addition of the dedicated short-circuit versions gdstk.all_inside and gdstk.any_inside, plus methods Polygon.contain, Polygon.contain_all, and Polygon.contain_any.

This version also introduces the new function gdstk.contour for the parametric generation of geometries similarly to contour plots.

Added

• contour function
• Polygon.transform to apply a general transformation to the polygon vertices
• Polygon.contain tests whether single points are inside the polygon
• Polygon.contain_all and Polygon.contain_any test multiple points with short circuit
• all_inside and any_inside test multiple points against multiple polygons with short circuit
• Alternative function interfaces in the C++ API

Fixed

• Holes in boolean results could lead to incorrect geometry in specific cases
• Bug in boolean operations resulting in self-intersecting polygons
• Bug in boolean operations with clockwise-oriented polygons
• Unsupported reccords found when loading a library generate a warning, not an error.

Changed

• inside has changed to use the better interfaces: grouping has been removed, scaling is not necessary, and short-circuit is implemented in all_inside and any_inside

Release v0.6.1

Minor bug fix release to fix the Library.read_oas (in Python) and gdstk::read_oas (in C++).

Release v0.6.0

Added

• Library.replace, used when adding cells with substitution of duplicate cell names
• Added pyproject.toml (thanks Ben Gollmer for the fix)

Changed

• Reference.cell is now writable

Fixed

• Bug in Array::insert not incerasing the array count
