pfstools 2.0.5-2build4 (arm64 binary) in ubuntu artful

 pfstools is a set of command line (and two GUI) programs for reading,
 writing, manipulating and viewing high-dynamic range (HDR) images and video
 frames. All programs in this package exchange data using a simple generic
 file format (pfs) for HDR data. It is an attempt to integrate existing file
 formats by providing a simple data format that can be used to exchange data
 between applications.
 .
 The concept of pfstools is similar to netpbm for low-dynamic range images.
