Package tritechgemini.imagedata

Class FanImageData

java.lang.Object

tritechgemini.imagedata.FanImageData

All Implemented Interfaces:

Cloneable

public class FanImageData
extends Object
implements Cloneable

Data for a fan shaped image. Note that this is only the data, not any type of actual image. It's in int16 (short)format, even though the maximum value should still be the max value from the sonars, which is 255, this allows setting all pixels outside the sonar image to be set to -1, which can then be made transparent when the data are finally converted into a buffered image.
