# Documentation

type Point = (Float, Float)Source

A point on the x-y plane.
Points can also be treated as `Vector`

s, so Graphics.Gloss.Data.Vector may also be useful.

A 2D picture

Blank | A blank picture, with nothing in it. |

Polygon Path | A polygon filled with a solid color. |

Line Path | A line along an arbitrary path. |

Circle Float | A circle with the given radius. |

ThickCircle Float Float | A circle with the given thickness and radius. If the thickness is 0 then this is equivalent to |

Text String | Some text to draw with a vector font. |

Bitmap Int Int ByteString | A bitmap image with a width, height and a ByteString holding the 32 bit RGBA bitmap data. |

Color Color Picture | A picture drawn with this color. |

Translate Float Float Picture | A picture translated by the given x and y coordinates. |

Rotate Float Picture | A picture rotated by the given angle (in degrees). |

Scale Float Float Picture | A picture scaled by the given x and y factors. |

Pictures [Picture] | A picture consisting of several others. |

# Rectangles

rectanglePath :: Float -> Float -> PathSource

A path representing a rectangle centered about the origin, with the given width and height.

rectangleWire :: Float -> Float -> PictureSource

A wireframe rectangle centered about the origin, with the given width and height.

rectangleSolid :: Float -> Float -> PictureSource

A solid rectangle centered about the origin, with the given width and height.

rectangleUpperPath :: Float -> Float -> PathSource

A path representing a rectangle in the y > 0 half of the x-y plane, with the given width and height

rectangleUpperWire :: Float -> Float -> PictureSource

A wireframe rectangle in the y > 0 half of the x-y plane, with the given width and height.

rectangleUpperSolid :: Float -> Float -> PictureSource

A sold rectangle in the y > 0 half of the x-y plane, with the given width and height.
