vwebp - decompress a WebP file and display it in a window
vwebp [options] input_file.webp
This manual page documents the vwebp command. 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. -noalphadither By default, quantized transparency planes are dithered during decompression, to smooth the gradients. This flag will prevent this dithering. -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.
