Picture to GDS

Python script to convert image files to GDSII files

Getting Started

This is a simple script for generating GDSII layout files from image files. The extension of the input file should be jpeg, jpg, png, pbm, pgm, or bmp. By specifying an input image file path, size of unit-cells (minimum width and space), and layer number of an output GDSII file, you can get a binary image file (image.bmp) and a GDSII layout file (image.gds).
