Method Detail

getShape

public static Shape getShape(String fileName)

Given the fileName of an image, possibly with a transparent background, return the Shape of the opaque part of the image

Parameters:

fileName - name of the image, loaded from the classpath

Returns:

the Shape

getShape

public static Shape getShape(String fileName,
                             int max)

Given the fileName of an image, possibly with a transparent background, return the Shape of the opaque part of the image

Parameters:

fileName - name of the image, loaded from the classpath

max - the maximum dimension of the traced shape

Returns:

the Shape

getShape

public static Shape getShape(Image image)

Given an image, possibly with a transparent background, return the Shape of the opaque part of the image

Parameters:

image - the image whose shape is to be returned

Returns:

the Shape

getShape

public static Shape getShape(Image image,
                             int max)

getShape

public static Shape getShape(BufferedImage image,
                             int max)

Given an image, possibly with a transparent background, return the Shape of the opaque part of the image

If the image is larger than max in either direction, scale the image down to max-by-max, do the trace (on fewer points) then scale the resulting shape back up to the layoutSize of the original image.

Parameters:

image - the image to trace

max - used to restrict number of points in the resulting shape

Returns:

the Shape
