Reading CurrentIPTCDigest

[Guenter]

Hi,
I am just confused how to decide to use IPTC or XMP contents.
The MWG clarified this a bit, but now I stuck on the CurrentIPTCDigest.

I have files they have IPTC contents, but the CurrentIPTCDigest is with no result:
exiftool -use MWG -currentiptcdigest -iptc:all file.eps
Envelope Record Version         : 4
Coded Character Set             : UTF8
Application Record Version      : 4
By-line                         : ..........
Time Created                    : 00:00:00+00:00
Copyright Notice                : ............

So far I understood, the CurrentIPTCDigest is build of the IPTC?
Now I stuck by comparing the CurrentIPTCDigest with IPTCDigest, which exists.

Has someone an idea or an explanation?

Thanks a lot

Hi Guenter,

CurrentIPTCDigest is only calculated for IPTC in the locations specified by the MWG recommendations.  This is defined only for JPEG, TIFF and PSD file formats.  Unfortunately, this is not specified for EPS files.

Hi Phil,
aahh, ok.
So, there is no option for EPS files to decide if the IPTC is valid or not; I have to guess.

Thanks for your fast answer!

Hi Guenter,

Looking at ExifTool's PostScript tags, it seems that IPTC is only decoded from one location anyway.  So I see no harm in unilaterally declaring this to be the "the standard location", and I will update ExifTool so that verison 9.00 will calculate the CurrentIPTCDigest for this.

Hi Phil,

I am looking forward for the 9.00.

Great job what you are doing here, many thanks
