       oiiotool - the OIIO Swiss Army Knife


       oiiotool [filename|option|action]...


       The oiiotool program will read images (from any file format for which an ImageInput plugin
       can be found), perform various operations on them, and write images  (in  any  format  for
       which an ImageOutput plugin can be found).

       The oiiotool utility is invoked as follows:

       oiiotool args

       oiiotool maintains an image stack, with the top image in the stack also called the current
       image. The stack begins containing no images.

       oiiotool arguments consist of image names, or commands. When an image name is encountered,
       that image is pushed on the stack and becomes the new current image.

       Most  other commands either alter the current image (replacing it with the alteration), or
       in some cases will pull more than one image off the stack (such as the current  image  and
       the next item on the stack) and then push a new image.

       For a complete description, see /usr/share/doc/openimageio-doc/openimageio.pdf.gz.
