Selecting the Data Window

You can define a window which limits the area where QckBool will booleanize data. This window can be defined in three ways:

• Manually - enter the coordinates of the window: for example, 0,0 10,10. Make sure of course that you use the same units as the GDSII file's units.



• Use Primary - this tells QckBool to calculate the extents of the primary operand and use those extents as the window - even if the extents of the secondary data are larger.



• Use Secondary - this tells QckBool to calculate the extents of the secondary operand and use those extents as the clipping window.
