Can you please provide me with a sample image which has these metadata in it?

DaphneW-AkoyaBio commented 2 years ago

I sent an email with 2 sample images with the requested metadata. Thanks for reviewing.

Dear Daphne, Can you please elaborate a bit on what you're trying to do. You say

I would like to be able to read in the tif and modify the tif tags, and then output a new tif file with the updated tif tags.

Which tags would you like to be able to do this with? Some of the tags you've listed above are fundamental to the image (e.g. ImageWidth) whereas others you might want to change (e.g. ImageDescription).

Hi,

I am also interested in that feature.

Precisely, being able to write ome-xml, i.e. add a xml string (type 2) tag number 270 in the 1st IFD. And also string info in tag 270 of the remaining IFDs in a multichannel tiff.
