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

vwebp [options] input_file.webp

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

-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.
