The general idea is to implement something resembling the GDSII file-format, but with some vectorized element types (eg. circles, not just polygons), better support for E-beam doses, and the ability to output to multiple formats.

Installation

Requirements:

python >= 3.7 (written and tested with 3.8)
numpy
matplotlib (optional, used for visualization functions and text)
python-gdsii (optional, used for gdsii i/o)
klamath (optional, used for gdsii i/o and library management)
ezdxf (optional, used for dxf i/o)
fatamorgana (optional, used for oasis i/o)
svgwrite (optional, used for svg output)
freetype (optional, used for text)

Install with pip:

pip3 install 'masque[visualization,gdsii,oasis,dxf,svg,text,klamath]'

Alternatively, install from git

pip3 install git+https://mpxd.net/code/jan/masque.git@release

Translation

Pattern: OASIS or GDS "Cell", DXF "Block"
SubPattern: GDS "AREF/SREF", OASIS "Placement"
Shape: OASIS or GDS "Geometry element", DXF "LWPolyline" or "Polyline"
repetition: OASIS "repetition". GDS "AREF" is a SubPattern combined with a Grid repetition.
Label: OASIS, GDS, DXF "Text".
annotation: OASIS or GDS "property"

TODO

Better interface for polygon operations (e.g. with pyclipper)
- de-embedding
- boolean ops
Construct polygons from bitmap using skimage.find_contours
Deal with shape repetitions for dxf, svg
