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.
Print usage summary.
Print version number and exit.
Don't use the ICC profile if present.
Don't use the fancy YUV420 upscaler.
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.
By default, quantized transparency planes are dithered during decompression, to smooth the gradients. This flag will prevent this dithering.
Fill transparent areas with the bitstream's own background color instead of checkerboard only. Default is white for non-animated images.
Use multi-threading for decoding, if possible.
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.
Toggle use of color profile.
Toggle display of background color.
Overlay file information.
Disable blending and disposal process, for debugging purposes.
- 'q' / 'Q' / ESC
