I'm working on an image processing application that needs to copy almost all available tags from one image file to another. The file formats may vary, for example JPEG in but TIFF out, or vice versa.
In experiments so far, it looks like this command will do exactly what I want:
exiftool -tagsFromFile infile.ext -all:all --all:icc_profile --all:colorspace outfile.ext
However, it would be great if I could split the copy into two phases: extract all the tags from infile.ext at one time, then at some later time store the tags into outfile.ext even if infile.ext is no longer available.
I experimented with using
exiftool -args infile.ext -all:all -g > alltags
but that didn't handle the binary information.
Then I tried
exiftool -args infile.ext -all:all -g -b > alltags
but that produced a result that I couldn't figure out how to interpret.
Is there some way to do a split-phase copy similar to -tagsFromFile, and if so, how?
Thanks!

Hi Rik,
Yes, the -args option is not compatible with -b.
There are a number of intermediate formats that support binary data. From the -b documentation:
May be combined with "-j", "-php" or "-X" to extract binary data
in JSON, PHP or XML format.
I recommend the XML format since you can use -tagsFromFile with it as you wanted.

Phil, many thanks -- that looks like it will work great!
