## 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

| ’c’ |  | Toggle use of color profile.
| ’b’ |  | Toggle display of background color.
| ’i’ |  | Overlay file information.
| ’d’ |  | Disable blending and disposal process, for debugging purposes.

’q’ / ’Q’ / ESC

Quit.
