net.grelf.image
Class FITS

java.lang.Object
  net.grelf.image.FITS

public class FITS
extends java.lang.Object

For loading and saving images as files in FITS format.
Loading will create an object implementing the interface net.grelf.image.Image. Notes:

1. Loads each image found in a file and holds its metadata (eg, exposure settings) as an ordered list.
2. For 3D arrays (FITS NAXES=3) it is assumed that the axis with the smallest length is the channels (bands) axis.
3. The code can create images with more than 3 channels if the the number of bits per channel is greater than 16. (In GRIP in that case only the first 3 channels will be displayed but the "Split channels" option on the levels menu will create as many monochrome images as there are channels. Any group of 3 can then be recombined via the image table.) If the image in the file has only 8 or 16 bits per channel then instead the file loader creates multiple monochrome images (and GRIP will display them all in separate frames).
