◆ GetSmallMapOwnerPixels()

uint32_t GetSmallMapOwnerPixels	(	TileIndex	tile,
		TileType	t,
		IncludeHeightmap	include_heightmap
	)

Return the colour a tile would be displayed with in the small map in mode "Owner".

Note: If include_heightmap is IH_NEVER, the return value can safely be used as a palette colour (by masking it to a uint8_t)

Parameters

tile	The tile of which we would like to get the colour.
t	Effective tile type of the tile (see SmallMapWindow::GetTileColours).
include_heightmap	Whether to return the heightmap/contour colour of this tile (instead of the default land tile colour)

Returns: The colour of tile in the small map in mode "Owner"

◆ GetSmallMapStationMiddle()

Point GetSmallMapStationMiddle	(	const Window *	w,
		const Station *	st
	)

Determine the middle of a station in the smallmap window.

Parameters

st	The station we're looking for.

Returns: Middle point of the station in the smallmap window.

◆ ShowSmallMap()

void ShowSmallMap ( )

Show the smallmap window.
