[digiKam-users] Embedded IPTC title in JPEG suddenly started to get truncated at 64 characters?

[hesyifei]

Previously (even just last week) Digikam was able to write titles of any length to a JPEG file's IPTC title field. However, yesterday I noticed that all new titles Digikam written into the JPEG are truncated at 64 characters. When I edited old files that previously had titles more than 64 characters, they also got truncated to only 64 characters.

The new titles still displayed fully inside Digikam (database), but when I check the JPEG with `exiftool -iptc:all`, the IPTC title field ("Object Name") is truncated (to exactly the first 64 characters) (old files' long Object Name are not truncated).

Also the title in sidecar xmp files didn't get truncated. It only happened with JPEG titles.

I don't think I have updated Digikam or changed any settings recently. What might be the cause, and how could I fix it? Thanks! :)

Hi,

Are you sure that you talking about IIM Iptc title ? Because, yes, IMM
Iptc fields are limited in size and encoding character. This is not
the cases of XMP IPTC Core which is an extension and evolution of IMM
IPTC.
