DESCRIPTION
This manual page documents the webpmux command.
webpmux can be used to create a WebP container file and extract/strip
relevant data from the container file.
OPTIONS
GET_OPTIONS (-get):
icc Get ICC profile.
exif Get EXIF metadata.
xmp Get XMP metadata.
frame n
Get nth frame.
SET_OPTIONS (-set)
icc file.icc
Set ICC profile.
Where: 'file.icc' contains the ICC profile to be set.
exif file.exif
