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
              Set EXIF metadata.

       Where: 'file.exif' contains the EXIF metadata to be set.

       xmp file.xmp
              Set XMP metadata.

       Where: 'file.xmp' contains the XMP metadata to be set.

   STRIP_OPTIONS (-strip)
       icc    Strip ICC profile.

       exif   Strip EXIF metadata.

       xmp    Strip XMP metadata.

   FRAME_OPTIONS (-frame)
       file_i +di[+xi+yi[+mi[bi]]]
              Where: 'file_i' is the i'th frame (WebP format), 'xi','yi' specify the image offset
              for  this  frame, 'di' is the pause duration before next frame, 'mi' is the dispose
              method for this frame (0 for NONE or 1 for BACKGROUND) and  'bi'  is  the  blending
              method  for  this  frame  (+b  for BLEND or -b for NO_BLEND).  Argument 'bi' can be
              omitted and will default to +b (BLEND).  Also, 'mi'  can  be  omitted  if  'bi'  is
              omitted  and  will default to 0 (NONE).  Finally, if 'mi' and 'bi' are omitted then
              'xi' and 'yi' can be omitted and will default to +0+0.

       -loop n
              Loop the frames n number of times. 0 indicates  the  frames  should  loop  forever.
              Valid range is 0 to 65535 [Default: 0 (infinite)].

       -bgcolor A,R,G,B
              Background color of the canvas.
              where:  'A',  'R',  'G'  and  'B' are integers in the range 0 to 255 specifying the
              Alpha,   Red,   Green   and   Blue   component   values   respectively    [Default:
              255,255,255,255].

   INPUT
       Input file in WebP format.

   OUTPUT (-o)
       Output file in WebP format.

   Note:
       The nature of EXIF, XMP and ICC data is not checked and is assumed to be valid.
