DescriptionThese routines provide
a high-level interface to a CCD-like image structure. read_image() reads
in a full image (which may be a cube), pointed to by the pointer iptr from
a file pointed to by the stream instr. It returns 0 in case of an error
(allocation), 1 if OK. On success iptr contains a valid address for an image.
iptr is allocated using malloc(3), and free_image() can be used to free
the space (free(3)) used by an image. write_image() writes the image pointed
to by iptr to a file outstr. create_image() is like read_image, but only
allocates space and sets most image header (except the size) variables
to zero. create_cube() is the extension of create_image() for 3D images.
copy_image copies an image, but not the image elements. All header elements
are copied. AuthorPeter Teuben See Alsoimage(5NEMO), fits(5NEMO) Files
