Introduction

The Qckvu Image Server Library [QISLib] is a powerful GDSII/OASIS database server that enables a client calling program to display and manipulate GDSII/OASIS data using a simple set of calls. As GDSII and OASIS files grow larger, many software developers are discovering that their own GDSII routines are no longer able to deal effectively with these large files -- they face the need to completely rewrite GDSII readers to handle files of 10,20 and even 50 GB.

QISLib can be used as a "toolkit" and eliminates the need to deal with the problems associated with opening and randomly accessing such large files. The OEM can focus on his core expertise and leave the heavy data manipulation to QISLib.

QFRACT - GDSII/OASIS Extract and Fracture

QFract reads either a GDSII/OASIS file as its input, selects all of the data or a window of the data and extracts it into memory. The extracted data is flattened, clipped to the window extents and fractured into trapezoids. Details
