# vwebp

## Name

`vwebp` -- Decompress a WebP file and display it in a window

## Synopsis

`vwebp [options] input_file.webp`

## Description

`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

`d`
:   Disable blending and disposal process, for debugging purposes.

`q` / `Q` / `Esc`
:   Quit
