Method: Color::YIQ#==

Defined in:
lib/extensions/pdf-writer/color/yiq.rb

#==(other) ⇒ Object

Compares the other colour to this one. The other colour will be converted to YIQ before comparison, so the comparison between a YIQ colour and a non-YIQ colour will be approximate and based on the other colour’s #to_yiq conversion. If there is no #to_yiq conversion, this will raise an exception. This will report that two YIQ values are equivalent if all component colours are within COLOR_TOLERANCE of each other.
