Each distinct command will take the form of a tuple (type, data). The `type` is the character string that defines the type of transformation in the transform data, so either of "translate", "rotate", "scale", "matrix", "skewX" and "skewY". Data is always a list of numbers contained within the transformation's parentheses. See the SVG documentation for the interpretation of the individual elements for each transformation. The main method is `parse(text)`. It can only consume actual strings, not filelike objects or iterators. c||_|j|j|j|j|j|jd|_t ddg|_y)N) translatescaleskewXskewYrotatematrixrr)lexerrule_1or2numbers rule_1numberrule_1or3numbers rule_6numberscommand_dispatchlist number_tokens)r r:s r r'z SVGTransformationParser.__init__s_ ..**&&&&++(( !
