Bezier | Bezier, line, rectangle and freehand drawing; rich editing tools such as node operations(add, delete, move, break, join), spline interpolation etc. |

Fourier | Fourier serie as a function |

Formula | mult-variable formula as a function |

Bitmap | bitmap as a function |

Functional curve | group of curves defined by fuctions such as fourier series, formulas |

Piecewise Curve | piecewise curve defined by other curves |

Envelope | repeated pattern around a base curve |

Filler | repeated pattern to fill the space enclosed by two curves. |

Copy | duplicates of items, the duplicates's positions, directions, sizes can be tweaked by any combination of path/curve, functions( fourier, formula, bitmap). |

Frame | frame created by user-defined region and path. |

Mesh | mesh defined by bezier |

Clip | items with clipping area |

Relief | curves to represent foreground by deforming background |

Random | randomize any base curve |

Mirror | clip, reflect and duplicate selected items. |

Engrave | varied width curves to represent bitmap |

predefined combination of operations | common-use combinations of simple operations |

Filter | deformations including 3D, curved mirror, envelope etc. |

Constant variables | constant variable support in formulas. |

Stroke & Fill | stroke & fill characteristic like line width, color etc. |
