We resolve them at the end. So, after this, we will have four + # moveto and four lineto variants: + # + # - 0moveto, 0lineto + # - hmoveto, hlineto + # - vmoveto, vlineto + # - rmoveto, rlineto + # + # and sixteen curveto variants. For example, a '0hcurveto' operator means a curve + # dx0,dy0,dx1,dy1,dx2,dy2,dx3,dy3 where dx0, dx1, and dy3 are zero but not dx3. + # An 'rvcurveto' means dx3 is zero but not dx0,dy0,dy3. + # + # There are nine different variants of curves without the '0'. Those nine map exactly + # to the existing curve variants in the spec: rrcurveto, and the four variants hhcurveto, + # vvcurveto, hvcurveto, and vhcurveto each cover two cases, one with an odd number of + # arguments and one without. Eg. an hhcurveto with an extra argument (odd number of + # arguments) is in fact an rhcurveto. The operators in the spec are designed such that + # all four of rhcurveto, rvcurveto, hrcurveto, and vrcurveto are encodable for one curve. + # + # Of the curve types with '0', the 00curveto is equivalent to a lineto variant. The rest + # of the curve types with a 0 need to be encoded as a h or v variant. Ie. a '0' can be + # thought of a "don't care" and can be used as either an 'h' or a 'v'. As such, we always + # encode a number 0 as argument when we use a '0' variant. Later on, we can just substitute + # the '0' with either 'h' or 'v' and it works. + # + # When we get to curve splines however, things become more complicated... XXX finish this. + # There's one more complexity with splines. If one side of the spline is not horizontal or + # vertical (or zero), ie. if it's 'r', then it limits which spline types we can encode. + # Only hhcurveto and vvcurveto operators can encode a spline starting with 'r', and + # only hvcurveto and vhcurveto operators can encode a spline ending with 'r'. + # This limits our merge opportunities later. + # + for i in range(len(commands)): + op, args = commands[i] + + if op in {"rmoveto", "rlineto"}: + c, args = _categorizeVector(args) + commands[i] = c + op[1:], args + continue + + if op == "rrcurveto": + c1, args1 = _categorizeVector(args[:2]) + c2, args2 = _categorizeVector(args[-2:]) + commands[i] = c1 + c2 + "curveto", args1 + args[2:4] + args2 + continue + + # 3.
