/*              Convert an Radiance image to APPLE pict format.

 *          V 1.1 (2/11/91)     -- Added options for Gamma

 *                              -- better about allocating buffers
 *          V 1.2 (19/11/91)    -- Revised to handle opening "The Radiance Way"
 *                              -- Added exposure level adjustment
