Data.GraphViz.Attributes.Colors

Contents

Description

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

When parsing and printing Color values (more specifically, the Brewer color values), the actual ColorScheme being used isn't taken into account. Also, the "/foo/bar" style of overriding the ColorScheme being used isn't supported for parsing purposes (and will result in a parsing failure).

Synopsis

Color schemes.

data ColorScheme Source

This represents the color schemes that Graphviz accepts. As mentioned above, these are not used for actual parsing or printing.

Constructors

X11 
BrewerScheme BrewerName Word8

The value of the scheme number depends on the name.

Instances

Instances

Colors

data Color Source

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.

Constructors

RGB 

Fields

red :: Word8
 
green :: Word8
 
blue :: Word8
 
RGBA 

Fields

red :: Word8
 
green :: Word8
 
blue :: Word8
 
alpha :: Word8
 
HSV

The hue, saturation and value values must all be 0 <= x <=1.

Fields

hue :: Double
 
saturation :: Double
 
value :: Double
 
X11Color X11Color 
BrewerColor Word8

This value should be between 1 and the level of the BrewerName being used.

Instances

data X11Color Source

The X11 colors that Graphviz uses. Note that these are slightly different from the "normal" X11 colors used (e.g. the inclusion of Crimson). Graphviz's list of colors also duplicated almost all Gray colors with Grey ones; parsing of an X11Color which is specified using "grey" will succeed, even for those that don't have the duplicate spelling (e.g. DarkSlateGray1).

Instances

Conversion to/from Colour.

toColour :: Color -> Maybe (AlphaColour Double)Source

Attempt to convert a Color into a Colour value with an alpha channel. The use of Maybe is because BrewerColor values cannot be converted without knowing which actual BrewerName and level color scheme is being used.

x11Colour :: X11Color -> AlphaColour DoubleSource

Convert an X11Color to its equivalent Colour value. Note that it uses AlphaColour because of Transparent; all other X11Color values are completely opaque.

fromColour :: Colour Double -> ColorSource

Convert a Colour value to an RGB Color.

fromAColour :: AlphaColour Double -> ColorSource

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").
