Hi,
quite long I have been searching the web for some hints or solutions on
how to extract embedded ICC profiles from TIFF and/or JPEG images
using Delphi (or some command line tools in worst case). But by now
I've found nothing useful. I found a lot on how to convert images
according to specific profiles, but the first step ist missing: how to
*get* the profile itself - or at least to determine, whether there is
a profile embedded in the file or not. I hope there is someone willing
an able to help !
Thanks in advance,
Peter
 

However, I had a look on the source of a different tool doing some
stuff with an embedded profile, and so I was able to find an easy
solution: you just have to look for the string "acsp" in the file,
which is the identification-String of an ICC-profile. After that, you
just have to find the size of the profile in its header and then have
to copy a block of that size in an extra file. that is all. At least it
worked out in several tests.
even with PNG, JPEG2000 and BMP, as the profile-identifier should'nt
change.
But thanks a lot for your ideas and code, if I run into trouble with
my approach I will give yours a try.
Thanks,
Peter
