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.

-h Print usage summary.
-version

-nofancy
Don't use the fancy YUV420 upscaler.
-nofilter

-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.
