public class FloatImage

extends Jimage

TeX FloatImage \copyright Turing Institute, 1998, W P Cockshott. A float image is one that stores its information as a vector of floats. It is initialised by explicitly passing in either bytes or floats.

Field Summary

float[][]	data TeX The data is stored as linear array of bytes for each plane
int	scanlinelength TeX The number of floats in a single scan line of the image data.
int	startindata TeX The position in the data at which the image origin ( top left ) occurs
