Salve in un progetto cerco di leggere i metadati (Copyright, Apertura, focale ecc..), per i file Jpeg nessun problema ma per i file .TIF legge solo pochi dati. Ho provato con ExifLib ed altre librerie senza risultati. Inoltre nella documentazione si richiede l'importazione della libreria System.Windows.Media.drawing che risulta impossibile importare per i progetti con i form. Cosa posso provare?

Hi in a project I try to read the metadata (Copyright, Apertura, focal etc ..), for the Jpeg files no problem but for the .TIF files it reads only a few data. I have tried with ExifLib and other libraries with no results. In addition, the documentation requires the import of the System.Windows.Media.drawing library which is impossible to import for projects with forms. What can I try?

What I have tried:

Dim exif As ExifTagCollection = New ExifTagCollection(fi)
      Dim tag As ExifTag

tag = exif(&H8298)
           Return tag.Value.ToString

Have you tried this: CompactExifLib: Access to EXIF Tags in JPEG, TIFF and PNG Files[^]
It specifically describes TIF support.

If that - and other packages - can't locate the TIF info, have you checked that the file contains the info you seek? And if so, that it's visible by Windows explorer / Properties for example?

Si già provato e mi da errore nella lettura. I dati nel file ci sono controllato da esplora risorse/proprietà. Grazie
