mkMat :: [Number] -> TransformFunction Source #
mkMat3d :: [Number] -> TransformFunction Source #
combine :: [TransformFunction] -> Reader Config [TransformFunction] Source #
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 Source #
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)
