Detailed Description

Function Documentation

void PShow_Net_Variable_Line_Weight ( int  count,
const HC_KEY keys,
char *  weight 
)

Similar to Show_Variable_Line_Weight(), but returns the net effective setting along a discrete segment path.

Parameters
count- The size of pathkeys
keys- An array of HC_KEY's delineating a path of segments.
weight- Scale factor applied to the line width. Returned to caller. Passed by reference always

DETAILS

As with all PShow_Net_* routines, pathkeys[0] represents the lowest (a.k.a the "most local" or "leaf"), and pathkeys[keycount-1] represents the highest segment. If the path is incomplete, missing segments are filled in if possible. Missing segments must be part of the same direct ancestry in order to be filled in. If the desired path contains an include link, the shortest unambiguous set of pathkeys would be [leaf, includelink, root], where includelink is the return value from Include_Segment().

By default, HOOPS will determine the Net attribute from the last specified key all the way to the root. If you add -1 at the end of the array, the PShow_Net routines will not proceed beyond the end of the last specified key.

void Show_Variable_Line_Weight ( char *  weight)

Show the current variable line weight setting.

Parameters
weight- Scale factor applied to the line width. Returned to caller. Passed by reference always

DETAILS

Show_Variable_Line_Weight() reads back the line weight setting as defined in a previous call to Set_Variable_Line_Weight().
