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.
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.
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.
Overlay file information.
Disable blending and disposal process, for debugging purposes.
- 'q' / 'Q' / ESC
