.\" Hey, EMACS: -*- nroff -*- .TH VWEBP 1 "November 25, 2016" .SH NAME vwebp \- decompress a WebP file and display it in a window .SH SYNOPSIS .B vwebp .RI [ options ] " input_file.webp .br .SH DESCRIPTION This manual page documents the .B vwebp command. .PP \fBvwebp\fP decompresses a WebP file and displays it in a window using OpenGL. .SH OPTIONS .TP .B \-h Print usage summary. .TP .B \-version Print version number and exit. .TP .B \-noicc Don't use the ICC profile if present. .TP .B \-nofancy Don't use the fancy YUV420 upscaler. .TP .B \-nofilter Disable in-loop filtering. .TP .BI \-dither " strength Specify a dithering \fBstrength\fP 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. .TP .BI \-noalphadither By default, quantized transparency planes are dithered during decompression, to smooth the gradients. This flag will prevent this dithering. .TP .B \-mt Use multi-threading for decoding, if possible. .TP .B \-info Display image information on top of the decoded image. .TP .BI \-\- " string Explicitly specify the input file. This option is useful if the input file starts with an '\-' for instance. This option must appear \fBlast\fP. Any other options afterward will be ignored. If the input file is "\-", the data will be read from \fIstdin\fP instead of a file. .TP .SH KEYBOARD SHORTCUTS .TP .B 'c' Toggle use of color profile. .TP .B 'i' Overlay file information. .TP .B 'd' Disable blending and disposal process, for debugging purposes. .TP .B 'q' / 'Q' / ESC Quit. .SH BUGS Please report all bugs to the issue tracker: https://bugs.chromium.org/p/webp .br Patches welcome!
