geIsPathReentrant( 
d_cellview 
l_points 
n_width 
[ t_style ] 
[ n_beginExt ] 
[ n_endExt ] 
)
=> t / nil 

Description

Determines whether a path is self-intersecting.

In a self-intersecting path, one part of the path overlaps another part of the path. The system calculates the outline of the path using the other arguments.

Arguments

d_cellview	Database ID of the cellview containing the path to check.
l_points	List of points making up the path.
n_width	Width of the path.
t_style	String defining an optional path style. If no style is given, the default is truncateExtend. Valid Values: truncateExtend, extendExtend, roundRound, varExtendExtend
n_beginExt	Beginning path extension. Default: 0.0
n_endExt	Ending path extension. Default: 0.0

Value Returned

t	The path is self-intersecting.
nil	The path is not self-intersecting.

Examples

The following example returns t.

geIsPathReentrant( geGetEditCellView( ) list( 0:0 10:10 0:10 10:0 ) 3.0 "truncateExtend" 1.0 0 )

The following example returns nil.

geIsPathReentrant( geGetEditCellView( ) list( 0:0 10:10 0:10 3.0 )
