static int [] org.quark.stegnos.SteganosUtil.convertByteToIntArray	(	byte[]	bytes,
		int	nbrBytes
	)

static

Create an integer array from a byte array.
This will pack an array of bytes into an array of integers. It is used to prepare text for inserting into the carrier image.

static byte [] org.quark.stegnos.SteganosUtil.convertIntToByteArray	(	int[]	data,
		int	nbrBytes
	)

static

Create a byte array from an integer array. Used when retrieving text from a stegan.

An integer array is created when first retrieving a text burden. This method can be used to unpack the bytes into a byte array

static byte [] org.quark.stegnos.SteganosUtil.getUTF8array ( String burden )

static

Convert a String burden to UTF-8 byte array

static boolean org.quark.stegnos.SteganosUtil.hasAlpha ( PImage img )

static

Detect whether an image has transparent pixels ie.e Alpha != 0xFF
