This module keeps names and easy handling
for easy color support. It gives you an easy
way to get colors from names.
A color is here an object, containing color
information and methods for conversion, see below.
Image.Color can be called to make a color object.
Image.Color() takes the following arguments:
Image.Color(string name) // "red"
Image.Color(string prefix_string) // "lightblue"
Image.Color(string hex_name) // "#ff00ff"
Image.Color(string cmyk_string) // "%17,42,0,19.4"
Image.Color(string hsv_string) // "%@327,90,32"
Image.Color(int red, int green, int blue)
The color names available can be listed by using indices
on Image.Color. The colors are available by name directly
as Image.Color.name, too:
...Image.Color.red...
...Image.Color.green...
or, maybe
import Image.Color;
...red...
...green...
...lightgreen...
Giving red, green and blue values is equal to calling
Image.Color.rgb ().
The prefix_string method is a form for getting modified
colors, it understands all modifiers
(light ,
dark ,
bright ,
dull and
neon ). Simply use
"method"+"color"; (as in lightgreen,
dullmagenta, lightdullorange).
The hex_name form is a simple
#rrggbb form, as in HTML or X-program argument.
A shorter form (#rgb) is also accepted. This
is the inverse to the Image.Color.Color->hex ()
method.
The cmyk_string is a string form of giving
cmyk (cyan, magenta, yellow, black) color. These
values are floats representing percent.
The hsv_string is another hue, saturation, value
representation, but in floats; hue is in degree range (0..360),
and saturation and value is given in percent. This is not
the same as returned or given to the hsv () methods!
