Detailed Description

A store for colors with a set of aliases.

The alias-sets are numbered where the 0'th plays the role of a default set.

Member Function Documentation

bool addAlias	(	const std::string &	name,
		const std::string &	alias,
		int	alias_set = 0
	)

adds a color alias (into the given alias-set)

Parameters

name	name/id of existing color
alias	new name

Returns

true if alias was stored or false if color name does not exists or alias names a color and is therefor rejected

void addColor	(	const Color &	color,
		const std::string &	name
	)

adds a color to the color store (to add the id call the function twice with id as name)

Color color

(

const std::string &

name_or_id_or_alias

)

const

retrieves a color with the given name/id/alias if no color is found that matches the id/alias then the default color is returned.

Always the alias-set 0 is checked first

Color color	(	const std::string &	name_or_id_or_alias,
		int	alias_set
	)		const

retrieves a color with the given name/id/alias from given alias_set if not found then the default alias_set (0) is checked

bool color	(	Color &	color,
		const std::string &	name_or_id_or_alias,
		int	alias_set = 0
	)		const

call by reference version returns false if color not found

bool existsColor

(

const std::string &

name

)

const

checks whether color with the name exists (no aliases are checked)

bool getColor ( Color &  c, const std::string &  name  ) const

protected

const Color & getDefaultColor

(

)

const

std::string getLoadErrorString

(

int

value

)

const

returns error string for value returned by loadPalette and loadAliases

int loadAliases	(	const std::string &	filename,
		int	alias_set_offset = 0
	)

loads aliases from text file with lines containing:
aliasname colorname/id [alias-set]

Parameters

alias_set_offset

number that is added to the alias_set number in the file

int loadPalette

(

const std::string &

gplfilename

)

loads a gpl (gimp pallette file) and returns the number loaded colors The name of the colors should not contain white spaces!

void print

(

std::ostream &

out

)

const

prints all colors and aliases

void setDefaultColor

(

const Color &

c

)
