pathFromString :: String -> IO [PathCommand]

convert a SVG path string into a list of commands

data PathCommand

Constructors

M_abs Tup

Establish a new current point (with absolute coords)

M_rel Tup

Establish a new current point (with coords relative to the current point)

Z

Close current subpath by drawing a straight line from current point to current subpath's initial point

L_abs Tup

A line from the current point to Tup which becomes the new current point

L_rel Tup

H_abs X

A horizontal line from the current point (cpx, cpy) to (x, cpy)

H_rel X

V_abs Y

A vertical line from the current point (cpx, cpy) to (cpx, y)

V_rel Y

C_abs (X1, Y1, X2, Y2, X, Y)

Draws a cubic Bzier curve from the current point to (x,y) using (x1,y1) as the ^control point at the beginning of the curve and (x2,y2) as the control point at the end of the curve.

C_rel (X1, Y1, X2, Y2, X, Y)

S_abs (X2, Y2, X, Y)

Draws a cubic Bzier curve from the current point to (x,y). The first control point is assumed to be the reflection of the second control point on the previous command relative to the current point. (If there is no previous command or if the previous command was not an C, c, S or s, assume the first control point is coincident with the current point.) (x2,y2) is the second control point (i.e., the control point at the end of the curve).

S_rel (X2, Y2, X, Y)

Q_abs (X1, Y1, X, Y)

A quadr. Bzier curve from the curr. point to (x,y) using (x1,y1) as the control point

Q_rel (X1, Y1, X, Y)

Nearly the same as cubic, but with one point less

T_abs Tup

T_Abs = Shorthand/smooth quadratic Bezier curveto

T_rel Tup

A_abs

A = Elliptic arc (not used)

A_rel
