Missing GIF Fields?

[blue-j]

I could be being a fool yet again - happens all the time! - but I am trying to trap for transparency, and in so doing noted that ExifTool does not appear to read these fields from GIF files?

https://exiftool.org/TagNames/GIF.html

It seems possible that the entire Graphic Control Extension is not extracted...?

I'm mostly concerned about Transparent Color Flag and Transparent Color Index, personally.

Thanks for the suggestion.

ExifTool 12.37 will extract TrasparentColor from GIF images.
