1.5.0 - viewer - save - TIFF - always adds EXIF Software metadata

Post by user0 »

XnViewMP 1.5.0 64bit
Windows11 (22H2), display resolution 3840x2160, win scaling 150%


Viewer - saving TIFF
app always adds EXIF Software on saving

To reproduce:
1. open any TIFF
2. press CTRL+S to save file
EXIF will have new Software metadata

Expected behaviour
It would be nice to not have this because it also adds after Cleaning metadata in Viewer, that is not acceptable.

The only way to clean metadata from TIFF is either via Viewer or Batch convert, in both ways there will be added extra Software tag.
Cleaning metadata, means no metadata shall be left, period. Its pure privacy issue.

So, something shall be changed:
- clean metadata routine OR
- saving routine
