Constructor Detail

NineBlockIdenticonRenderer2

public NineBlockIdenticonRenderer2()

Constructor.

Method Detail

getPatchSize

public float getPatchSize()

Returns the size in pixels at which each patch will be rendered before they are scaled down to requested identicon size.

Returns:

the size

setPatchSize

public void setPatchSize(float size)

Set the size in pixels at which each patch will be rendered before they are scaled down to requested identicon size. Default size is 20 pixels which means, for 9-block identicon, a 60x60 image will be rendered and scaled down.

Parameters:

size - patch size in pixels

getBackgroundColor

public Color getBackgroundColor()

setBackgroundColor

public void setBackgroundColor(Color backgroundColor)

render

public BufferedImage render(BigInteger code,
                            int size)

Description copied from interface: IdenticonRenderer

Returns rendered identicon image for given identicon code.

Specified by:

render in interface IdenticonRenderer

Parameters:

code - identicon code

size - image size

Returns:

identicon image

render

public BufferedImage render(int code,
                            int size)

Returns rendered identicon image for given identicon code.

Size of the returned identicon image is determined by patchSize set using setPatchSize(float). Since a 9-block identicon consists of 3x3 patches, width and height will be 3 times the patch size.

Specified by:

render in interface IdenticonRenderer

Parameters:

code - identicon code

size - image size

Returns:

identicon image

renderQuilt

protected BufferedImage renderQuilt(int code,
                                    int size)
