I am trying to write EXIF 2.2.
I wrote ExifIFD:Version and a 2.2 verifier program I have indicates that I am missing two mandatory tags: PixelXDimension, PixelYDimension.
I tried passing them on the command line and didn't see them in the documentation.
perl c:\exiftool\exiftool -ExifIFD:PixelXDimension=300 orientation1.jpg
Tag 'PixelXDimension' does not exist
Nothing to do.
Exchangeable image file format for digital still cameras: Exif Version 2.2
Established in April, 2002
Prepared by Technical Standardization Committee on AV & IT Storage Systems and Equipment
Published by Japan Electronics and Information Technology Industries Association
defines:
PixelXDimension
Information specific to compressed data. When a compressed file is recorded, the valid width of the meaningful image shall be recorded in this tag, whether or not there is padding data or a restart marker. This tag should not exist in an uncompressed file. For details see section 2.8.1 and Annex F.
Tag = 40962 (A002.H)
Type = SHORT or LONG
Count = 1
Default = none
PixelYDimension
Information specific to compressed data. When a compressed file is recorded, the valid height of the meaningful image shall be recorded in this tag, whether or not there is padding data or a restart marker. This tag should not exist in an uncompressed file. For details see section 2.8.1 and Annex F. Since data padding is unnecessary in the vertical direction, the number of lines recorded in this valid image height tag will in fact be the same as that recorded in the SOF.
Tag = 40963 (A003.H)
Type = SHORT of LONG
Count = 1
Is someone actively working on adding new tags to the ExifTool?

EXIF tag name documentation for details.
