transform

public EmittedLayout transform(EmittedLayout el)

Description copied from interface: LayoutTransformer

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

Specified by:

transform in interface LayoutTransformer

See Also:

LayoutTransformer.transform(samples.preview_new_graphdraw.EmittedLayout)

adjustSize

public void adjustSize(java.awt.Dimension d)

Description copied from interface: LayoutTransformer

Adjusts this transformer to be working in this size a space

Specified by:

adjustSize in interface LayoutTransformer

See Also:

LayoutTransformer.adjustSize(java.awt.Dimension)

supportsInvert

public boolean supportsInvert()

Description copied from interface: LayoutTransformer

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.

Specified by:

supportsInvert in interface LayoutTransformer

Returns:

true if the layout can be inverted.

See Also:

LayoutTransformer.supportsInvert()

invert

public Coordinates invert(Coordinates in)

Modifies the input Coordinates object to reverse the input transformation.

Specified by:

invert in interface LayoutTransformer

LayoutTransformer.invert(samples.preview_new_graphdraw.Coordinates)
