iptcembed - weird problem

I'm experimenting with the iptcparse and iptcembed functions, but with the embedding something goes wrong

I have an image and in Photoshop 7 I embed soms file info (copyright, source, ...)

I use the iptcembed function to edit this info, so every item is set to "test." A

fterwards I use the iptcparse function to read the info : it displays the correct, every item has been set to "test".

But when I download the image and I read the manipulated file info in Photoshop, it displays the old date.


Even if I use the IPTC class (http://phpdorks.net/docs/api/pear/Image/Image_IPTC.html#class_details) it doesn't work in Photoshop (7 or CS)

Anyone an idea?

which block are you reading/writing to? i believe 13 is the most widely used..

Yes, I use block 13. Sorry for posting anonymously, my mistake.

you can view the code on : http://www.multimedium.be/ben/iptc_test.phps

Thanks in advance!

i think your code is messed up.. there's no starting php tag and everything is in a big un-formatted chunk

I see the code fine...and it works fine...

I think the problem is with Photoshop, not your code. You see, photoshop stores the IPTC data within its own APP13 markers. The meta-data that you are seeing in photoshop is not the IPTC data, but meta-data that is photoshop specific.

If you use any other IPTC viewing utility you will see that the tags have been changed properly....

Thanks a lot, this explains why I don't see the changed IPTC data in Photoshop.

Finally my mysterious problem solved!

Euhm, I still have one little question. Is there a possibility to erase the photoshop-specific metadata? Or how can I manipulate this data, so the user eventually will see the php-generated iptc data in photoshop?

You should be able to modify the data, but I don't know the specifics on how it is stored. I believe there is a SDK for photoshop you can download from adobe's web site that explains how the data is stored.
