Hi all,
I have looked around on the forum to see whether some similir question was posed before but didn't find it.
A friend of mine is a professional photographer and has recently loaded his last 2 years of footage into Picasa.
He's using a Mac. It turns out that the <return> character he used in his "description" field, is neglected in Picasa.
So what I would like to do is create a batch program that goes over all his jpg photos, open the metadata, scan for the <return> character, replace it by a , and save the file.
Is something like that possible with the ExifTool?
Kind regards,
Ricky
Hi Ricky,
Yes. Substitutions like this may be done with user-defined tags. See this post (https://exiftool.org/forum/index.php/topic,2961.msg13270.html#msg13270) for an example. You might want a conversion something like this:
ValueConv => ''$val =~ tr/\n/,/ ? $val : undef',
This will return an undefined value if nothing was replaced (which is what you want, because then the value will be copied only when it contains a newline. There is one variable, however. What type of newline is it? Maybe it is safer to do this:
ValueConv => ''$val =~s/(\x0d\x0a|0x0d|\x0a)/,/g ? $val : undef',
To replace any of the various combinations.
The command line will look something like this:
exiftool "-description<mydescription" DIR
