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.

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].
