DESCRIPTION
       This manual page documents the webpmux command.

       webpmux can be used to create/extract from animated WebP files, as well
       as to add/extract/strip XMP/EXIF metadata and ICC profile.

OPTIONS
   GET_OPTIONS (-get):
       icc    Get ICC profile.

       exif   Get EXIF metadata.

       xmp    Get XMP metadata.

       frame n
              Get nth frame from an animated image. (n = 0 has a special mean‐
              ing: last 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)
       Create an animated WebP file from multiple (non-animated) WebP images.

       file_i +di[+xi+yi[+mi[bi]]]
              Where: 'file_i' is the i'th frame (WebP format), 'xi','yi' spec‐
              ify 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  (infi‐
              nite)].

       -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.

EXAMPLES
       Add ICC profile:
       webpmux -set icc image_profile.icc in.webp -o icc_container.webp

       Extract ICC profile:
       webpmux -get icc icc_container.webp -o image_profile.icc

       Strip ICC profile:
       webpmux -strip icc icc_container.webp -o without_icc.webp

       Add XMP metadata:
       webpmux -set xmp image_metadata.xmp in.webp -o xmp_container.webp

       Extract XMP metadata:
       webpmux -get xmp xmp_container.webp -o image_metadata.xmp

       Strip XMP metadata:
       webpmux -strip xmp xmp_container.webp -o without_xmp.webp

       Add EXIF metadata:
       webpmux -set exif image_metadata.exif in.webp -o exif_container.webp

       Extract EXIF metadata:
       webpmux -get exif exif_container.webp -o image_metadata.exif

       Strip EXIF metadata:
       webpmux -strip exif exif_container.webp -o without_exif.webp

       Create an animated WebP file from 3 (non-animated) WebP images:
       webpmux -frame 1.webp +100 -frame 2.webp +100+50+50
               -frame 3.webp +100+50+50+1+b -loop 10 -bgcolor 255,255,255,255
               -o anim_container.webp

       Get the 2nd frame from an animated WebP file:
       webpmux -get frame 2 anim_container.webp -o frame_2.webp

       Using -get/-set/-strip with input file name starting with '-':
       webpmux -set icc image_profile.icc -o icc_container.webp -- ---in.webp
       webpmux -get icc -o image_profile.icc -- ---icc_container.webp
       webpmux -strip icc -o without_icc.webp -- ---icc_container.webp
