Method Detail

pack

public java.util.Collection<java.awt.Rectangle> pack(java.util.Collection<java.awt.Rectangle> rectangles,
                                                     RectanglePacker packer)
                                              throws java.lang.IllegalArgumentException

Packs the supplied rectangles using a bounds generator.

Parameters:

rectangles - The rectangles that should be packed.

packer - The packer to pack the generated bounds with.

Returns:

The rectangles that were packed or an empty collection if unable to pack all rectangles.

Throws:

java.lang.IllegalArgumentException - If any rectangles are empty (zero length dimensions).

java.lang.IllegalArgumentException - If any bounds generated by generator have width or height <= 0.

getBounds

public java.awt.Dimension getBounds()

Returns the packed bounding rectangle.

Returns:

getNumBoundsTested

public int getNumBoundsTested()

Returns the number of bounding rectangles that the RectanglePacker attempted to pack whether or not the packing was successful.

Returns:

the number of bounding rectangles tested.

getPackedRectangles

public java.util.Collection<java.awt.Rectangle> getPackedRectangles()

Returns the rectangles that were packed.

Returns:

the packed rectangles.
