TransformAttribute: transform

In mslegrand/svgR: svgR is an R DSL to generate svg markup

Description

Sets an orderd list of transform definitions to be applied prior to rendering..

Available Attribute Values

The value is defined as follows:

<tranform-list>

Specifies a named list of coordinate transforms. The order in which the transforms are applied is given by the order in the list.

Details

A transform-list is named list of coordinate transforms to be applied in the order in which they appear. For example: list(translate=c(100,20), scale=1.2, rotate=c(30,100,20)) The list names and corresponding values (all numeric) are summarized in the following table Transforms

name	value	action
matrix	a 2x3 matrix m.	Transforms coordinates x,y to x'y' by c(x',y',1)<-m %*% c(x,y,1), where m'<-rbind(m,c(0,0,1).
translate	x or c(x,y)	Translates by c(x, y). If only x is specified, y is set to 0.
scale	sx or c(sx, sy)	Scales by sx, sy. If only sx is specified, sy=sx.
rotate	θ or c( θ,x,y).	Rotates by theta degrees about the point c(x,y). If only the θ is specified, then x=y=0.
skewX	θ_x	Skews along the x-axis by an angle of θ_x , where θ_x is interpreted in units of degrees.
skewY	θ_y	Skews along the y-axis by an angle of θ_y , where θ_y is interpreted in units of degrees.
