Method Summary

void	adjustSize(Dimension d) Adjusts this transformer to be working in this size a space
Coordinates	invert(Coordinates in) This does the *reverse* of the trasformation, for a given point.
boolean	supportsInvert() Most functions should support invert.
EmittedLayout	transform(EmittedLayout el) Transforms the given layout.

Method Detail

adjustSize

void adjustSize(Dimension d)

Adjusts this transformer to be working in this size a space

transform

EmittedLayout transform(EmittedLayout el)

Transforms the given layout. May (but needn't) return the same layout object, albeit somewhat stomped-upon.

supportsInvert

boolean supportsInvert()

Most functions should support invert. If your layout transformer can't be inverted, this should return false. Note that having even one layout be un-invertible makes the whole pipeline un-invertble.

Returns:

true if the layout can be inverted.

invert

Coordinates invert(Coordinates in)

This does the *reverse* of the trasformation, for a given point. This should be quite fast, as it's done in interactive time (e.g. while a user is dragging around a vertex).

Parameters:

in -
