vwebp decompresses a WebP file and displays it in a window using OpenGL.

−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.

’q’ / ’Q’ / ESC

Quit.
