Herror T_query_colored(Htuple* PossibleNumberOfColors)

void QueryColored(HTuple* PossibleNumberOfColors)

static HTuple HInfo::QueryColored()

static void HOperatorSet.QueryColored(out HTuple possibleNumberOfColors)

static HTuple HInfo.QueryColored()

def query_colored() -> Sequence[int]

Description

query_coloredquery_coloredQueryColoredQueryColoredquery_colored returns all possible parameter values for set_coloredset_coloredSetColoredSetColoredset_colored. set_coloredset_coloredSetColoredSetColoredset_colored defines how many colors are used for region or graphics output.
