Method Details

getInitialOffset

public Point getInitialOffset(Word word,
 Rectangle cloudArea)

Description copied from interface: ILayouter

Calculates the initial offset of the given word, within the bounds of the specified rectangle. The layout algorithm will try to find a matching position around the initial offset.

Specified by:

getInitialOffset in interface ILayouter

Parameters:

word -

cloudArea -

layout

public boolean layout(Point offset,
 Word word,
 Rectangle cloudArea,
 CloudMatrix mainTree)

Tries to position the given word in the given area. First a start point is chosen, then the RectTree of the word and the main area is used to detect whether the word can be placed at the given position, or not. If not, the current point is moved slightly in a spiral manner, similar to the approach of Wordle.

Specified by:

layout in interface ILayouter

Parameters:

offset -

word -

cloudArea -

mainTree -

setOption

public void setOption(String optionName,
 Object object)

Description copied from interface: ILayouter

Set Layouter-specific options. See DefaultLayouter as an example.

Specified by:

setOption in interface ILayouter

Parameters:

optionName -

object -
