About modifying the sorting of the output TIFF image data

[beiwei]

When deleting some Tags of TIFF images, I found that the value of StripOffsets was different from the original file. After checking it, I wanted to modify the data order (IFH, IFD, image data) of the output TIFF format. I modified the generateTIFF () function in exif.pm, and the final file is as follows:

At the command line:

perl C:\windows\exiftool.pl -Orientation= blk_tif.tif

The error is as follows:

Code Select Expand

Warning: Sorry, Orientation is not writable

Nothing to do.
Why is this, how should I modify, thanks for the reply.

I would like to add that my operating system is win10 and the version of exiftool is 12.65. I look forward to your reply

This will require Phil's attention but he is away for at least another week.

The GenerateTIFF() function is used only to generate the ThumbnailTIFF information when extracting.  Changing the order of the IFDs/data when writing a TIFF image would be quite complicated.
