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.
