Name

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

Synopsis

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
