convert 6.9.5-0 Q16 - "unknown image property error"

[bill_raynor]

I am trying to extract IPTC and EXIF data from some scanned images. When I enter the command

Code: Select all

convert test.tif  -format "%[IPTC:2:05]" info:

or

Code: Select all

 convert test.tif  -format "%[IPTC:2:120]" info:

I get an error like

Code: Select all

convert: unknown image property "%[IPTC:2:05]" @ warning/property.c/InterpretImageProperties/3780.

What am I doing wrong? I get the same error using both MacPorts and HomeBrew/

Thx

OS X 10.11.5 using the "current" MacPorts installation (installed today).

Are you sure your camera has them stored in the picture?

What to you get from

Code: Select all

identify -verbose test.tif

If those specific meta data are not there or there is no IPTC profile listed, then I do not think the string format will find them?

(I am not a professional photographer and cannot find any of my images that have IPTC data, only EXIF in the verbose information. So I have never actually tried to access any IPTC data)

What do you get from

Code: Select all

convert -version

in terms of your delegates, though I am not sure whether some delegate is actually needed or not?

Can you post your image to some free hosting such as dropbox.com and put the URL here?

I am on OSX SnowLeopard and have used MacPorts to load my delegates, but install IM from source.

Thanks. My error. The program I use to edit the EXIF data (EXifChanger) apparently doesn't write the changes immediately, so the test.tif file didn't have a Caption. Hence the error. Thank you both for your help.
