Instances

Eq TransformFunction

Methods

(==) :: TransformFunction -> TransformFunction -> Bool

(/=) :: TransformFunction -> TransformFunction -> Bool

Show TransformFunction

Methods

showsPrec :: Int -> TransformFunction -> ShowS

show :: TransformFunction -> String

showList :: [TransformFunction] -> ShowS

ToText TransformFunction

Methods

toText :: TransformFunction -> Text

toBuilder :: TransformFunction -> Builder

Minifiable TransformFunction

Methods

minify :: TransformFunction -> Reader Config TransformFunction

mkMat :: [Number] -> TransformFunction

mkMat3d :: [Number] -> TransformFunction

combine :: [TransformFunction] -> Reader Config [TransformFunction]

Combines consecutive <transform-functions> whenever possible, leaving translate functions that can't be converted to a matrix (because they use percentages or relative units) as they are, in the position they are in the list (since matrix multiplication isn't commutative) Example:

>>> import Control.Monad.Reader
>>> let t10 = Translate (Right (Length 10 PX)) Nothing
>>> let s45 = Skew (Angle 45 Deg) Nothing
>>> let sx5 = ScaleX 5
>>> let f x = runReader (combine x) defaultConfig

>>> fmap toText $ f [t10, s45, sx5]
["matrix(5,0,1,1,10,0)"]

>>> let tp  = Translate (Left (Percentage 100)) Nothing
>>> fmap toText $ f [s45,tp,sx5,sx5,sx5]
["skew(45deg)","translate(100%)","scale(125)"]

simplify :: TransformFunction -> Reader Config TransformFunction

Simplifies a <transform-function> without converting it to a 4x4 matrix, by doing some simple conversions between the different functions, or minifying the dimension arguments (<length> and <angle> values)
