invisible

public static final Color invisible

This color is used to tag items which should not be drawn. Users should test to see if this color is set, and then simply not draw the relevant figures. Simply drawing with this color will probably not have the desired effect. This color can be selected only by name.

Method Detail

get

this method returns a Color. Colors are supposedly immutable and are returned from the same table. The RGBA formats, where Alpha is optional and defaults to 1, are:

      by name:          "yellow"                      , where alpha is always 1.0
      by int r,g,b,a:   "128, 255, 64, 255"           , where alpha (a) is optional
      by float r,g,b,a: "0.5, 1.0, 0.25, 1.0"         , where alpha (a) is optional
      by single number: "64637" or "0x0FFF08"         , where alpha is always 1.0
 

Parameters:

name - name/number of the color

Returns:

requested Color or defaulting to white in case of a invalid name (message is printed).
