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.
-noalphadither
By default, quantized transparency planes are dithered during decompression, to smooth the gradients. This flag will prevent this dithering.
-usebgcolor
Fill transparent areas with the bitstream's own background color instead of checkerboard only. Default is white for non-animated images.
-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

'b'

'i'

'd'
