color_best_contrast()

QColor color_best_contrast	(	const QColor &	subject,
		const QColor *	candidates,
		int	ncandidates
	)

Find the colour from 'candidates' with the best perceptual contrast from 'subject'.

color_brightness_score()

int color_brightness_score

(

const QColor &

color

)

Return a number indicating the perceptual brightness of this color relative to others (larger is brighter).

color_system_free()

void color_system_free

(

struct color_system *

colors

)

Called when the client first starts to free any allocated colors.

Definition at line 66 of file colors_common.cpp.

color_system_read()

struct color_system* color_system_read

(

struct section_file *

file

)

Called when the client first starts to allocate the default colors.

Currently this must be called in ui_main, generally after UI initialization.

get_color()

QColor get_color	(	const struct tileset *	t,
		enum color_std	stdcolor
	)

Return a pointer to the given "standard" color.

get_player_color()

QColor get_player_color	(	const struct tileset *	t,
		const struct player *	pplayer
	)

Return the color of the player.

In pregame, callers should check player_has_color() before calling this.

get_terrain_color()

QColor get_terrain_color	(	const struct tileset *	t,
		const struct terrain *	pterrain
	)

Return a pointer to the given "terrain" color.

player_has_color()

bool player_has_color	(	const struct tileset *	t,
		const struct player *	pplayer
	)

Return whether the player has a color assigned yet.

Should only be FALSE in pregame.
