Functions

void PShow_Net_Color_Map_Count (int key_count, const HC_KEY *path_keys, int *count)

Function Documentation

void Show_Color_Map_Count ( int *  count)

Shows the number of entries in the current virtual color map.

Parameters:
count- The number of colors contained in the current color map. Returned to caller. Passed by reference in all languages.

DETAILS

Show_Color_Map_Count() gives you back the length of the current colormap. This may be handy if you're about to call Show_Color_Map() and need to know how much space to allocate.

See also:
Set_Color_Map, Set_Color, Show_One_Color_Map.
void PShow_Net_Color_Map_Count ( int  key_count,
const HC_KEY *  path_keys,
int *  count 
)

Similar to Show_Color_Map_Count(), but returns the net effective value of the attribute(s) along a path of segments specified by an array of HC_KEY's.

Parameters:
key_count- The size of the keys array
path_keys- The list of keys starting with the owning segment and following all the way back to the root segment or other desired segment.
count- The number of colors contained in the current color map. Returned to caller. Passed by reference in all languages.

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.
