$dictionary = Color::Library->dictionary( <dictionary_id> ) Returns a Color::Library::Dictionary object corresponding to <dictionary_id> @dictionaries = Color::Library->dictionaries @dictionaries = Color::Library->dictionaries( <dictionary_id>, <dictionary_id>, ... ) $dictionaries = Color::Library->dictionaries( <dictionary_id>, <dictionary_id>, ... ) In list context, returns a list of Color::Library::Dictionary objects (for each <dictionary_id> passed in In scalar context, returns a hash of Color::Library::Dictionary objects mapping a dictionary id to a dictionary When called without arguments, the method will return all dictionaries $color = Color::Library->color( <query> ) Returns a Color::Library::Color object found via <query> A query can be any of the following: color name A color name is like "blue" or "bleached-almond" color title A color title is like "Dark Green-Teal" color id A color id is in the form of <dictionary_id>:<color_name>, for example: "x11:azure1" color( <query>, <query>, ... ) In list context, returns a list of Color::Library::Color objects corresponding to each <query> In scalar context, just returns the first <query> color( <dictionaries>, <query>, ... ) If an array reference is passed as the first argument, then this indicates that the array is a list of dictionary ids to search through (in order): # Search in the svg and x11 dictionaries for a match my $blue = Color::Library->color([qw/svg x11/], "blue"); # Will not find "aquamarine1" in the svg dictionary, so it will try the x11 dictionary my $aquamarine1 = Color::Library->color([qw/svg x11/], "aquamarine1"); $color = Color::Library->colors $color = Color::Library->colour $color = Color::Library->colours All are aliases for the above color method ABOUT
This package was inspired by Graphics::ColorNames, and covers much of the same ground. However, I found the Graphics::ColorNames interface difficult to use. I also wanted to list colors directly in the perldoc, which this package does. SEE ALSO
