# Documentation

A 2D picture

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

Polygon Path | A convex 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 |

Arc Float Float Float | A circular arc drawn counter-clockwise between two angles (in degrees) at the given radius. |

ThickArc Float Float Float Float | A circular arc drawn counter-clockwise between two angles
(in degrees), with the given radius and thickness.
If the thickness is 0 then this is equivalent to |

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

Bitmap BitmapData | A bitmap image. |

BitmapSection Rectangle BitmapData | A subsection of a bitmap image where the first argument selects a sub section in the bitmap, and second argument determines the 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 clockwise 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. |

# Aliases for Picture constructors

thickCircle :: Float -> Float -> Picture Source #

A circle with the given thickness and radius.
If the thickness is 0 then this is equivalent to `Circle`

.

arc :: Float -> Float -> Float -> Picture Source #

A circular arc drawn counter-clockwise between two angles (in degrees) at the given radius.

thickArc :: Float -> Float -> Float -> Float -> Picture Source #

A circular arc drawn counter-clockwise between two angles (in degrees),
with the given radius and thickness.
If the thickness is 0 then this is equivalent to `Arc`

.

bitmap :: BitmapData -> Picture Source #

A bitmap image

bitmapSection :: Rectangle -> BitmapData -> Picture Source #

a subsection of a bitmap image first argument selects a sub section in the bitmap second argument determines the bitmap data

translate :: Float -> Float -> Picture -> Picture Source #

A picture translated by the given x and y coordinates.

rotate :: Float -> Picture -> Picture Source #

A picture rotated clockwise by the given angle (in degrees).

scale :: Float -> Float -> Picture -> Picture Source #

A picture scaled by the given x and y factors.

# Compound shapes

circleSolid :: Float -> Picture Source #

A solid circle with the given radius.

arcSolid :: Float -> Float -> Float -> Picture Source #

A solid arc, drawn counter-clockwise between two angles at the given radius.

sectorWire :: Float -> Float -> Float -> Picture Source #

A wireframe sector of a circle. An arc is draw counter-clockwise from the first to the second angle at the given radius. Lines are drawn from the origin to the ends of the arc.

A path representing a rectangle centered about the origin

rectangleUpperPath :: Float -> Float -> Path Source #

A path representing a rectangle in the y > 0 half of the x-y plane.
