Data.GraphViz.Attributes.Colors

This module defines the various colors, etc. for Graphviz. For information on colors in general, see: http://graphviz.org/doc/info/attrs.html#k:color For named colors, see: http://graphviz.org/doc/info/colors.html

Note that the ColorBrewer Color Schemes (shortened to just "Brewer" for the rest of this module) are covered by the following license (also available in the LICENSE file of this library): http://graphviz.org/doc/info/colors.html#brewer_license

datadata Color

Defining a color for use with Graphviz. Note that named colors have been split up into X11Colors and those based upon the Brewer color schemes.

A Color tagged with an optional weighting.

valuetoWC :: Color -> WeightedColor

For colors without weightings.

valuetoColorList :: [Color] -> ColorList

For a list of colors without weightings.

classclass NamedColor nc where

More easily convert named colors to an overall Color value.

valuetoWColor :: NamedColor nc => nc -> WeightedColor

Conversion to/from `Colour`.

3 declarations

valuetoColour :: Color -> Maybe (AlphaColour Double)

Attempt to convert a Color into a Colour value with an alpha channel. The use of Maybe is because the RGB values of the BrewerColors haven't been stored here (primarily for licensing reasons).

valuefromColour :: Colour Double -> Color

Convert a Colour value to an RGB Color.

valuefromAColour :: AlphaColour Double -> Color

Convert an AlphaColour to an RGBA Color. The exception to this is for any AlphaColour which has alphaChannel ac == 0; these are converted to X11Color Transparent (note that the Show instance for such an AlphaColour is "transparent").
