[Openexr-devel] Re: [Openexr] KeyKode

Hi Ken,

The Kodak KeyKode (the 'K' is trademarked) spec uses another hierachy than
the one you suggested.
see
http://www.kodak.com/US/plugins/acrobat/en/motion/postProduction/keykode/35mm.pdf
(similar document are available for 16/65mm)

This reordering is just to make others aware that perfOffset is the least
significant counter.

     struct keyCode
     {
         char filmMfgCode[2];
         char filmType[2];
         char prefix[6];       // 6-digit roll number
         char count[4];        // foot counter
/*!*/    char perfOffset[2];   // this is counting and interpolated 
                               // between barcodes
    };

The barcode uses USS-128 encoding but AFAIK only digits are used/allowed.
