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.
-usebgcolor Fill transparent areas with the bitstream's own background color instead of checkerboard only. Default is white for non-animated images.
-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.
'c' Toggle use of color profile.
'b' Toggle display of background color.
'i' Overlay file information.
'd' Disable blending and disposal process, for debugging purposes.
'q' / 'Q' / ESC Quit.
