Graphics.Rendering.Diagrams.Attributes

Attributes which can be added as annotations to a Diagram, implemented via instances of AttrClass.

Documentation

defaultAttributes :: Diagram -> Diagram

Apply all the default attributes to a Diagram.

fillColor :: Color c => c -> Diagram -> Diagram

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 -> Diagram

fc is provided as a convenient short synonym for fillColor.

lineColor :: Color c => c -> Diagram -> Diagram

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 -> Diagram

lc is provided as a convenient short synonym for lineColor.

lineWidth :: Double -> Diagram -> Diagram

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 -> Diagram

lw is provided as a convenient short synonym for lineWidth.

lineCap :: LineCap -> Diagram -> Diagram

Set the line cap style. Valid values for LineCap are LineCapButt, LineCapRound, and LineCapSquare.

data LineCap

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

dashing

Arguments

:: [Double]

a list specifying alternate lengths of on and off portions of the stroke. The empty list indicates no dashing.

-> Double

an offset into the dash pattern at which the stroke should start

-> Diagram

-> Diagram

Set the line dashing pattern.

typeface :: String -> Diagram -> Diagram

Change the default typeface to one named.

tf :: String -> Diagram -> Diagram

Convenience function to change the typeface.

stretch :: Double -> Double -> Diagram -> Diagram

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 -> Diagram

Scale by the same scaling factor in both dimensions, so the diagram retains its aspect ratio.

scaleX :: Double -> Diagram -> Diagram

Scale a diagram along the x-axis only. scaleX s is equivalent to stretch s 1.

scaleY :: Double -> Diagram -> Diagram

Scale a diagram along the y-axis only. scaleY s is equivalent to stretch 1 s.

translate :: Double -> Double -> Diagram -> Diagram

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 -> Diagram

Translate a diagram along the x-axis only. translateX x is equivalent to translate x 0.

translateY :: Double -> Diagram -> Diagram

Translate a diagram along the y-axis only. translateY y is equivalent to translate 0 y.

rotate :: Double -> Diagram -> Diagram

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 -> Diagram

rotateR r rotates a diagram clockwise by r radians.
