Plug-In Example: A simple window extraction of polygons

This is a very simple plug-in example (on Windows) that shows a developer how to define a rectangular window on screen and then extract all of the polygons and boundaries that cross that window.

How It Works

The user opens a GDSII or OASIS file

The user sets the structure to view (usually the top structure)

The user turns on any layers that data should be extracted from.

the plug-in is started

the user specifies a window (on screen using the mouse)

The user selects an output file name

The users clicks OK and the resulting polygons are written to a disk file

A flash video of this process can be seen here
