Description

I tried to set metadata to a tif, but return fail message "Invalid ifdId 98", Error from "tags.cpp",
ExifKey::ExifKey(uint16_t tag, const std::string& groupName)
: p_(new Impl) {
IfdId ifdId = groupId(groupName);
// Todo: Test if this condition can be removed
if (!Internal::isExifIfd(ifdId) && !Internal::isMakerIfd(ifdId)) {
throw Error(23, ifdId);
}
const TagInfo* ti = tagInfo(tag, ifdId);
if (ti == 0) {
throw Error(23, ifdId);
}
p_->groupName_ = groupName;
p_->makeKey(tag, ifdId, ti);
}
The "groupName" value is "(Last IFD item)", so runs "throw Error(23, ifdId);"
My command line like this:
exiv2 -M "set Exif.Image.DateTime 2011-01-01" c:\err.tif

And I use the 2.21 version.

History

#1 Updated by Kent Fu over 6 years ago

This bug appears in the multi-page tiff´╝î when greater than 4 frame count.

#2 Updated by Guillaume Paumier over 6 years ago

I hit the same bug ("Invalid ifdId 98") while trying to add metadata to a TIFF picture in digiKam. (This is a bit annoying since many of my pictures are TIFFs, so I can't process them =)

Here's the bug report: https://bugs.kde.org/show_bug.cgi?id=271757

using LibExiv2: 0.21.1 compiled from source. Exiv2 says it can write to TIFF files.

  • Category set to tiff parser

Kent's comment is spot-on. This is a shortcoming of Exiv2 for TIFFs with more than four chained IFDs. Fixin this requires surgery on the TIFF parser and is not straightforward to do properly. As a workaround, it wouldn't be difficult to extend the list of known chained IFDs, say to 20.

Related to this is the issue that Exif group names should be assigned intelligently rather than statically. Historically, Exiv2 calls the group for IFD0 "Image" and that for the next IFD "Thumbnail", in line with the Exif specification. For multi-page TIFFs this doesn't make sense though. Something like "Image", "Image2", "Image3", etc. would be more appropriate.
