This is the information I got so far about ISO IPI/IFF:

- In May 1990 ISO/IEC/JTC1/SC24/WG1 approved it as a "New Work
  Item Proposal on Imaging" (document N138).
- There is an article about IPI in IEEE Computer Graphics &
  applications, March 1991, pp 61-70, "Requirements for the First
  International Imaging Standard" written by Christof Blum, Georg
  Rainer Hofmann and Detlef Kroemker.
- You may contact Rainer Hofmann at FhG-AGD, Germany. His
  FAX number is +49-6151-155-119. He is the editor of Part 3
  of the standard (IFF). His adress is

    Fraunhofer Computer Graphics Research Institute
    Wilhelminenstr. 7
    W-6100 Darmstadt
    Germany

- There is also a well known Amiga format called IFF. But this
  seems to have nothing to do with the ISO standard. IPI
  means Image Processing and Interchange Standard, IFF means
  Image Interchange Format.
- IFF is ASN.1 encoded. This means it is compatible with OSI.
- The IPI standard has three parts:

    1. the common imaging architecture
    2. the application interface (API)
    3. the image interchange format (IFF)

- IFF is based on a file format developped 1987 in Germany
  (FTCRP = File for the Transfer of Colored Raster Pictures)

I am looking forward to further information. Thanks to
Murray Gilbert for some interesting information about
Amiga IFF.

Have fun ...

Markus
