java.lang.Object skyview.survey.Image
public class Image
This class defines an image as the combination of a set of pixel values and a WCS describing the pixel coordinates. some subclasses of the Image class may be 'read-only' images and may throw an Error if the user attempts to set the data values.
Field Summary | |
---|---|
protected double[] |
data
The data in the image. |
Constructor Summary | |
---|---|
Image()
Null constructor to be used in overriding classes |
|
Image(double[] data,
WCS wcs,
int width,
int height)
Construct an image given the data and WCS with default depth |
|
Image(double[] data,
WCS wcs,
int width,
int height,
int depth)
Construct an image given the data and WCS with specified depth |
