i want to modify some tags of a tiff file, but if i open a file by TIFFOpen with a mode parameter "w", all the context was cleaned, any suggestion on this subject?
Zhaoguang,
You can open the file in "update mode" using the access string "r+". However, libtiff isn't generally oriented to in-place-update so there are alot of things that can go wrong.
Best regards,
