LiveCode Forums.

Greetings,

I am trying to figure out how to write metadata to a jpeg file. I have searched the forums, and it seems that this is a complex problem. Has anybody done this successfully?

Thanks,
John Miller

Hi John
I never tried this, but there are some helpful resources about the specifications and tools that do this sort of job that could be useful for you to investigate:

http://netzreport.googlepages.com/hidde ... files.html gives lots of links to specifications (Exif, IPTC, XMP) and a couple of good tools with source.
