# Masque README
|
|
|
|
Masque is a Python module for designing lithography masks.
|
|
|
|
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:
|
|
```bash
|
|
pip3 install 'masque[visualization,gdsii,oasis,dxf,svg,text,klamath]'
|
|
```
|
|
|
|
Alternatively, install from git
|
|
```bash
|
|
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
