ratios (GradientGlowFilter.ratios property)
public ratios : Array
An array of color distribution ratios for the corresponding colors in the colors array. Valid
values are 0 to 255.
The ratios property cannot be changed by directly modifying its values. Instead, you must
get a reference to ratios, make the change to the reference, and then set ratios to the
reference.
The colors, alphas, and ratios properties are all related. The first element in the colors
array corresponds to the first element in the alphas array and in the ratios array, and so on.
Think of the gradient glow filter as a glow that emanates from the center of the object (if the
distance value is set to 0), with gradients that are stripes of color blending into each other.
The first color in the colors array is the outermost color of the glow. The last color is the
innermost color of the glow.
