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 ~/src/pjt/image image.c image.h image.3 image.5
