.TH CWEBP 1 "March 1, 2011"
|
||||
.SH NAME
|
||||
cwebp \- compress an image file to a WebP file
|
||||
.SH SYNOPSIS
|
||||
.B cwebp
|
||||
.RI [ options ] " input_file -o output_file.webp
|
||||
.br
|
||||
.SH DESCRIPTION
|
||||
This manual page documents the
|
||||
.B cwebp
|
||||
command.
|
||||
.PP
|
||||
\fBcwebp\fP compresses image using the WebP format.
|
||||
Input format can be either PNG, JPEG, or raw Y'CbCr samples.
|
||||
When using PNG, the transparency information (alpha channel) is currently
|
||||
discarded.
|
||||
.SH OPTIONS
|
||||
The basic options are:
|
||||
.TP
|
||||
.B \-o string
|
||||
Specify the name of the output WebP file. If omitted, \fBcwebp\fP will
|
||||
perform compression but only report statistics.
|
||||
.TP
|
||||
.B \-h, \-help
|
||||
A short usage summary.
|
||||
.TP
|
||||
.B \-H, \-longhelp
|
||||
A summary of all the possible options.
|
||||
.TP
|
||||
.B \-q float
|
||||
Specify the compression factor between 0 and 100. Small factor
|
||||
produce smaller file with lower quality. Best quality is achieved
|
||||
using a value of 100. The default is 75.
|
||||
.TP
|
||||
.B \-f int
|
||||
Specify the strength of the deblocking filter, between 0 (no filtering)
|
||||
and 100 (maximum filtering). A value of 0 will turn off any filtering.
|
||||
Higher value will increase the strength of the filtering process applied
|
||||
after decoding the picture. The higher the smoother the picture will
|
||||
appear. Typical values are usually in the range of 20 to 50.
|
||||
.TP
|
||||
.B \-preset string
|
||||
Specify a set of pre-defined parameters to suit a particular type of
|
||||
source material. Possible values are: \fBdefault\fP, \fBphoto\fP,
|
||||
\fBpicture\fP, \fBdrawing\fP, \fBicon\fP, \fBtext\fP.
|
||||
.TP
|
||||
.B \-sns int
|
||||
Specify the amplitude of the spatial noise shaping. Spatial noise shaping
|
||||
(or \fBsns\fP for short) refers to a general collection of built-in algorithms
|
||||
used to decide which area of the picture should use relatively less bits,
|
||||
and where else to better transfer these bits. The possible range goes from
|
||||
0 (algorithm is off) to 100 (the maximal effect). The default value is 80.
|
||||
.TP
|
||||
.B \-m int
|
||||
Specify the compression method to use. This parameter controls the
|
||||
tradeoff between encoding speed and the compressed file size and quality.
|
||||
Possible values range from 0 to 6. Default value is 4.
|
||||
When higher values are used, the encoder will spend more time inspecting
|
||||
additional encoding possibilities and decide on the quality gain.
|
||||
Lower value can result is faster processing time at the expense of
|
||||
larger filesize and lower compression quality.
|
||||
.TP
|
||||
.B \-af
|
||||
Turns auto-filter on. This algorithm will spend additional time optimizing
|
||||
the filtering strength to reach a well-balanced quality.
|
||||
|
||||
.SH ADDITIONAL OPTIONS
|
||||
More advanced options are:
|
||||
.TP
|
||||
.B \-sharpness int
|
||||
Specify the sharpness of the filtering (if used).
|
||||
Range is 0 (sharpest) to 7 (least sharp). Default is 0.
|
||||
.TP
|
||||
.B \-strong
|
||||
Use a stronger filtering than the default one (if filtering is being
|
||||
used thanks to the \fB\-f\fP option). Strong filtering is off by default.
|
||||
.TP
|
||||
.B \-segments int
|
||||
Change the number of partitions to use during the segmentation of the
|
||||
sns algorithm. Segments should be in range 1 to 4. Default value is 4.
|
||||
.TP
|
||||
.B \-size int
|
||||
Specify a target size (in bytes) to try and reach for the compressed output.
|
||||
Compressor will make several pass of partial encoding in order to get as
|
||||
close as possible to this target.
|
||||
.TP
|
||||
.B \-psnr float
|
||||
Specify a target PSNR (in dB) to try and reach for the compressed output.
|
||||
Compressor will make several pass of partial encoding in order to get as
|
||||
close as possible to this target.
|
||||
.TP
|
||||
.B \-pass int
|
||||
Set a maximum number of pass to use during the dichotomy used by
|
||||
options \fB\-size\fP or \fB\-psnr\fP. Maximum value is 10.
|
||||
.TP
|
||||
.B \-crop x_position y_position width height
|
||||
Crop the source to a rectangle with top-left corner at coordinates
|
||||
(x_position, y_position) and size width x height. This cropping area must
|
||||
be fully contained within the source rectangle.
|
||||
.B \-s width height
|
||||
Specify that the input file actually consists of raw Y'CbCr samples following
|
||||
the ITU-R Bt.601 recommendation, in 4:2:0 linear format.
|
||||
The luma plane has size \fBwidth\fP x \fBheight\fP.
|
||||
.TP
|
||||
.B \-map int
|
||||
Output additional ASCII-map of encoding information. Possible map values
|
||||
range from 1 to 6. This is only meant to help debugging.
|
||||
.TP
|
||||
.B \-pre int
|
||||
Specify a pre-processing filter. This option is a placeholder
|
||||
and has currently no effect.
|
||||
.TP
|
||||
.B \-v
|
||||
Print extra information (encoding time in particular).
|
||||
.TP
|
||||
.B \-quiet
|
||||
Do not print anything.
|
||||
.TP
|
||||
.B \-short
|
||||
Only print brief information (output file size and PSNR) for testing purpose.
