# 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.

|
|
|
* numpy
|
|
|
|
|
* matplotlib (optional, used for `visualization` functions and `text`)
|
|
|
|
|
* python-gdsii (optional, used for `gdsii` i/o)
|
|
|
|
|
* 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]'
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
Alternatively, install from git

|
|
|
|
|
|
|

|
|
|
|
|
* Construct from bitmap
|
