IPTC processing with NConvert?
Please add possibility to read/set IPTC fields.
Something like:
-iptcread caption dog.jpg
prints "This is my dog"
-iptcwrite special_instruction "apply sharpening and crop" dog.jpg
sets the field
-iptcclear copyright *.jpg
clears field
An option can be read options from file, like:
-iptcbatch batch_file.cmd
And batch_file.cmd contains lines like:
read caption dog.jpg
write special_instruction "apply sharpening and crop" dog.jpg
clear copyright *.jpg
Option to skip setting value if field is already set.

Re: IPTC processing with NConvert?
because I tried this:
nconvert.exe -iptc_print Keywords "img.jpg"
nconvert.exe -iptc_print 25 "img.jpg" (25 is the id of the keyword field)
nconvert.exe -iptc_print IPTC.Application2.Keywords "img.jpg" (as in exiv2)
All unsuccessfully
nconvert.exe -iptc_print Keywords "img.jpg"
nconvert.exe -iptc_print 25 "img.jpg" (25 is the id of the keyword field)
nconvert.exe -iptc_print IPTC.Application2.Keywords "img.jpg" (as in exiv2)
All unsuccessfully
Re: IPTC processing with NConvert?
To be able to use -iptc_print you must use -infoMistic100 wrote:because I tried this:

and the good one is
Code: Select all
nconvert.exe -iptc_print 25 "img.jpg"

Re: IPTC processing with NConvert?
ok it works
but nconvert can't add/set iptc tags without reprocessing the picture ?
if not I will continue to use exiv2

Re: IPTC processing with NConvert?
I don't know if lossless is the good term, but just add tags, without touch the rest of the file
exiv2 can do it (I compared the two picture, they are exactly the same, just a difference of 10 Bytes for a 6 chars lenght tag) so why not nconvert ?
ps : I don't really like exiv2 ^^ its application is very specific and the exe is 3,4MB and must come with a .dll
