Constructors

Constructor	Description
ImageDataCompressed(int[] image, int width, int height)	Constructor from the array of the real unsigned values.
ImageDataCompressed(UByteArray image, int width, int height)	Constructor from the wrapped array of values, without the metadata.
ImageDataCompressed(UByteArray image, AbstractMetadata metadata)	Constructor from the wrapped array of values and from the metadata which contains also the width and the height.

Method Summary

Modifier and Type	Method	Description
int	getDataElementMaxValue()	Returns the maximal value that can be stored in the returned data array: 255 which is the maximum of unsigned byte.
boolean	isCompressed()	Returns always true because ImageData are based on UByteArray.
