hi,
when allowing users to edit EXIF data thanks to PEL, it happens that
data is wrong and that some fields should be dropped. it seems to work
well with ASCII and RATIONAL files to do $val->setValue(null), but with
the timestamp, whatever i set it to, if it is not valid, it returns
"1970-01-01 01:00:00". as this is a valid timestamp, one cannot use it
as a placeholder for empty data.
more generally, is there a method for totally erasing a PelEntry, a
PelIfd or a Section?
thx,
andré
