long setSymbolSize(string ck, float size, short unitsEnum)
This method sets the size of the symbol with CARIS Key ck to size, where size has the units given by unitsEnum. The latter is either 0, 1, or 2, indicating pixels, meters, or feet, respectively. If unitsEnum indicates pixels, the size is relative to the view, i.e. the symbol size remains the same as the view is zoomed in or out; otherwise, the size is relative to the Earth's surface, i.e. the symbol size increases/decreases as the view is zoomed in/out.
The method returns zero upon success, and returns an error code if
- unitsEnum is out of range.
- No feature is found with CARIS Key ck.
- The feature found is not a symbol.
