Enumeration Type Documentation

TransparencyOption

enum TransparencyOption

Transparency option bits: which position in _transparency_opt stands for which transparency.

If you change the order, change the order of the ShowTransparencyToolbar() stuff in transparency_gui.cpp too. If you add or remove an option don't forget to change the transparency 'hot keys' in main_gui.cpp.

Enumerator
TO_SIGNS	signs
TO_TREES	trees
TO_HOUSES	town buildings
TO_INDUSTRIES	industries
TO_BUILDINGS	company buildings - depots, stations, HQ, ...
TO_BRIDGES	bridges
TO_STRUCTURES	other objects such as transmitters and lighthouses
TO_CATENARY	catenary
TO_TEXT	loading and cost/income text
TO_INVALID	Invalid transparency option.
