Constant values that describe path segment operators in PDE path elements.

## Values:

IG_PDE_MOVE_TO |
0 |
Designates m (moveto) operator, which moves the current point. |

IG_PDE_LINE_TO |
1 |
Designates l (lineto) operator, which appends a straight line segment from the current point. |

IG_PDE_CURVE_TO |
2 |
Designates c (curveto) operator, which appends a Bezier curve to the path. |

IG_PDE_CURVE_TO_V |
3 |
Designates v (curveto) operator, which appends a Bezier curve to the current path when the first control point coincides with initial point on the curve. |

IG_PDE_CURVE_TO_Y |
4 |
Designates y (curveto) operator, which appends a Bezier curve to the current path when the second control point coincides with final point on the curve. |

IG_PDE_RECT |
5 |
Designates re operator, which adds a rectangle to the current path. |

IG_PDE_CLOSE_PATH |
6 |
Designates h (closepath) operator, which closes the current subpath. |
