Propagate TIFF tags

[peter01242]

I have to read a TIFF file, add a bar code to it and save it back to the original file.
The source TIFF may contain tags not recognize by IM, even if they are in a valid TIFF tag format.
Is it possible to have IM retain those tags and write them to the target file (also TIFF) even though it does not recognize them?

Thanks,

Pete Young

IM is essentially a raster image processor. It doesn't bother with or record metadata that isn't required for that purpose.

If you use IM to read a tiff, process it and write a tiff, and you also want other metadata copied, exiftool is your friend.
