Changed Features

This chapter describes the features that were changed in this release of the LEF application programming interface.

Layer Routines

The following syntax has been added to the listed layer routines.

lefiGeometries

     int colorMask;

void addPath(int colorMask);

lefiLayer

     void setMask(int num);

int hasMask() const;

Int mask() const;

These are described below:

 

setMask(int num)	Sets the color mask number on the layer.
hasMask()	Checks whether the layer has a color mask assigned to it or not.
mask()	Returns the color mask number of the layer.

lefiViaLayer

     void addRect(int mask,

     double xl,

     double yl

     double xh

     double yn);

void addPoly(int mask,

     lefiGeometries* geom);
