AbstractImageData

protected AbstractImageData(AbstractUnsignedArray image,
int width,
int height)

Constructor from the wrapped array of values, without the metadata.

Parameters:

image -

width -

height -

AbstractImageData

protected AbstractImageData(AbstractUnsignedArray image,
int width,
int height,
ImageMetadata metadata)

Constructor from the wrapped array of values and from the metadata.

Parameters:

image -

AbstractImageData

protected AbstractImageData(int[] image,
int width,
int height,
ImageMetadata metadata)

Stub of the constructor from a recounted array of values. Subclasses are expected to extend this constructor to set the member field of the image values by performing a check of the array values to fit for the particular backing data type (unsigned short[], unsigned byte[])

Parameters:

image -

width -

height -

metadata -

Method Details

isCompressed

public abstract boolean isCompressed()

Returns whether the data values of the image are of byte[].

Returns:

getData

public int[] getData()

Returns the data of the image as int[]. The values are of one of int's subtype, bounded by getDataElementMaxValue().

Returns:

getDataElementMaxValue

public abstract int getDataElementMaxValue()

Returns the maximal value that can be stored in the returned data array.

Returns:

setData

public abstract void setData(int[] data)

Sets the image data. Subclasses check the parameter whether it fits for the particular subtype (unsigned byte[], unsigned short[]).

Parameters:

data -

getMetadata

public ImageMetadata getMetadata()

Returns the image metadata.

Returns:

getInputStream

public InputStream getInputStream()

Gets an InputStream of the backing array.

Returns:

getWidth

public int getWidth()

Returns width of the image.

Returns:

getHeight

public int getHeight()

Returns height of the image.

Returns:

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

toString

public String toString()

Overrides:

toString in class Object
