NAME
       vwebp - decompress a WebP file and display it in a window

SYNOPSIS
       vwebp [options] input_file.webp

DESCRIPTION
       This manual page documents the vwebp command.

       vwebp  decompresses  a  WebP  file  and  displays  it in a window using
       OpenGL.

OPTIONS
       -h     Print usage summary.

       -version
              Print version number and exit.

       -noicc Don't use the ICC profile if present.

       -nofancy
              Don't use the fancy YUV420 upscaler.

       -nofilter
              Disable in-loop filtering.

       -dither strength
              Specify a dithering strength between 0 and 100. Dithering  is  a
              post-processing  effect  applied  to  chroma components in lossy
              compression.  It helps by smoothing gradients and avoiding band‐
              ing artifacts. Default: 50.

       -mt    Use multi-threading for decoding, if possible.

       -info  Display image information on top of the decoded image.

       -- string
              Explicitly  specify the input file. This option is useful if the
              input file starts with an '-' for  instance.  This  option  must
              appear  last.   Any  other options afterward will be ignored. If
              the input file is "-", the data will be read from stdin  instead
              of a file.



       KEYBOARD SHORTCUTS

       'c'    Toggle use of color profile.

       'i'    Overlay file information.

       'q' / 'Q' / ESC
              Quit.
