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 banding 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.
