Increase the size of the ‘Image description’ field display to 4 kB.

Post by Otto_Riehl »

In XnView MP, Info panels, EXIF tab, the display of the ‘Image description’ field is limited to 2,048 characters. The following image has an entry with 3,794 characters.
Note: Downloading will result in a reduced image! I can provide the original.

I learned my working method 12 years ago from an expert. He wrote his findings in his images as EXIF data.

My request: Increase the size of the ‘Image description’ field in the Info panels, EXIF tab display to 4 kB.

Addition to my request:
IPTC:Caption-Abstract is limited to 2000 characters in the IPTC/IM specifications.
EXIF:Image Description and XML:Description are not directly limited.
The total amount of EXIF data in a JPEG image is limited to 64 KB. Data larger than 64 KB can only be written to a sidecar file.

Metadata > Edit IPTC... only allows 2 KB of data – OK.
Metadata > Edit XML... allows more than 3.7 KB of data (I have not tested the maximum) – OK.

My sample file has 3747 characters in the description.

The info area in XnView MP shows:
  • EXIF displays 2049 characters in a larger field. I would like to see a larger display (4 KiB) here.
  • IPTC-IIM displays 2030 characters in one line. Copy value only returns a subset.
  • XML displays 259 characters in one line. Copy value only returns a subset.
  • Exiftool displays in one line
    - EXIF:Image Description 3747 characters. OK
    - XML:Description 3747 characters. OK
    - IPTC:Caption-Abstract 1995 characters. OK
Image management > Quick info (tooltip ) > {EXIF:Image Description} displays 1024 characters.
Image view > Information > {EXIF:Image Description} displays 1024 characters. I would like to see a larger display here (4 KiB).
