Title: How to tell an 8-bit indexed PNG from a 24 bit RGB PNG
Post by: goofy166 on March 08, 2018, 02:07:52 PM

Is there a way to use ExifTool from the command line to determine the bit depth of a PNG?
I am using Photoshop to do this and it seems to give me contradictory results. Specifically I am using the Photoshop File->File Info menu.

Thanks

Mitch

Try running ExifTool on the file.

HAHA very funny. It can't be that easy. Are you saying I just go C:>EXIFTOOL MYFILE.PNG
