Metadata - unify 'Clean metadata' dialog

Post by user0 »

XnViewMP 1.4.3 64bits
Windows11 64bit (22H2), display resolution 3840x2160, win scaling 150%


'Clean metadata'
1) Why are these 'Clean metadata' dialogs different?
2) Why does EXIF ​​still remain after being selected for removal in Viewer/Batch mode?
3) What exctly is this underscore mark ( _ ) metadata, remained after cleaning via Viewer/Batch?
metadata_unify_'Clean metadata'_menu.png
test_metadata_clear.zip

Suggestion
  • unify 'Clean metadata' dialog in Browser, Viewer and Batch Convert.
  • remove 'Optimize Huffman table' as it is format specific (jpeg only?) and not related to metadata in other formats.
    It shall be somewhere in format Write settings
  • controls' vertical alignment shall be Top, not 'Stretched across' as it results in gapes between them if dialog is resized.

Potential bug:
'Clean metadata' in Viewer mode:
- available for the file without metadata (in Browser mode it is disabled if file has no metadata)
- resets DPI of image file without metadata, test file available here. File's DPI was 72x18 and became 72x72 after 'Clean metadata'.

Q: Shouldn't we prevent deleting copyrights in images?

This dialog shall be as simple as possible and delete ALL metadata.
Because copyright data is no more important than any other metadata field. Today one user will ask to add settings to keep field A from deletion, the next day another one will ask to keep field B, and so on, resulting in overcomplicated dialog.

There shall be another instrument for editing/deleting any metadata field(s) for single file or in batch.
