Documentation
defaultAttributes :: Diagram -> DiagramSource
Apply all the default attributes to a Diagram.
fillColor :: Color c => c -> Diagram -> DiagramSource
Draw a diagram using the given fill color. Note that the new color only applies to parts of the diagram which are not otherwise colored; subdiagrams which already have an explicit fill color will not be affected. The default fill color is completely transparent.
fc :: Color c => c -> Diagram -> DiagramSource
fc is provided as a convenient short synonym for fillColor.
lineColor :: Color c => c -> Diagram -> DiagramSource
Draw a diagram using the given color for lines. Note that the new color only applies to parts of the diagram which are not otherwise colored; subdiagrams which already have an explicit line color will not be affected. The default line color is black.
lc :: Color c => c -> Diagram -> DiagramSource
lc is provided as a convenient short synonym for lineColor.
lineWidth :: Double -> Diagram -> DiagramSource
Draw shape outlines and lines with the given width. Note that the line width is invariant under uniform scaling, although under non-uniform scaling (scaling by different amounts in the x and y axes) lines can become distorted. The default line width is 1.
lw :: Double -> Diagram -> DiagramSource
lw is provided as a convenient short synonym for lineWidth.
lineCap :: LineCap -> Diagram -> DiagramSource
Set the line cap style. Valid values for LineCap are LineCapButt, LineCapRound, and LineCapSquare.
data LineCap Source

Specify line endings.

LineCapButt
Start(stop) the line exactly at the start(end) point.
LineCapRound
Use a round ending, the center of the circle is the end point.
LineCapSquare
Use squared ending, the center of the square is the end point
Constructors
LineCapButt
LineCapRound
LineCapSquare
lineJoin :: LineJoin -> Diagram -> DiagramSource
Set the line join style. Valid values for LineJoin are LineJoinMiter, LineJoinRound, and LineJoinBevel.
data LineJoin Source
Specify how lines join.
Constructors
LineJoinMiter
LineJoinRound
LineJoinBevel
dashingSource
:: [Double]a list specifying alternate lengths of on and off portions of the stroke. The empty list indicates no dashing.
-> Doublean offset into the dash pattern at which the stroke should start
-> Diagram
-> Diagram
Set the line dashing pattern.
typeface :: String -> Diagram -> DiagramSource
Change the default typeface to one named.
tf :: String -> Diagram -> DiagramSource
Convenience function to change the typeface.
stretch :: Double -> Double -> Diagram -> DiagramSource
Stretch a diagram by a separate scaling factor for each axis. stretch w h scales by a factor of w in the x direction and a factor of h in the y direction.
scale :: Double -> Diagram -> DiagramSource
Scale by the same scaling factor in both dimensions, so the diagram retains its aspect ratio.
scaleX :: Double -> Diagram -> DiagramSource
Scale a diagram along the x-axis only. scaleX s is equivalent to stretch s 1.
scaleY :: Double -> Diagram -> DiagramSource
Scale a diagram along the y-axis only. scaleY s is equivalent to stretch 1 s.
translate :: Double -> Double -> Diagram -> DiagramSource
Translate a diagram by the given relative offsets in the x and y directions. Note that the positive x-axis is to the right, while the positive y-axis points downwards.
translateX :: Double -> Diagram -> DiagramSource
Translate a diagram along the x-axis only. translateX x is equivalent to translate x 0.
translateY :: Double -> Diagram -> DiagramSource
Translate a diagram along the y-axis only. translateY y is equivalent to translate 0 y.
rotate :: Double -> Diagram -> DiagramSource
rotate f rotates a diagram clockwise by fraction f of a complete revolution. rotate f is equivalent to rotateR (2*pi*f).
rotateR :: Double -> Diagram -> DiagramSource
rotateR r rotates a diagram clockwise by r radians.
