📄 ImageMagick.1 .TH ImageMagick 1 "2020-04-25" "ImageMagick" .SH NAME ImageMagick \- a free software suite for the creation, modification and display of bitmap images. .SH SYNOPSIS \fBmagick\fP [\fIoptions\fP\|\fIinput-file\fP]... \fIoutput-file\fP \fBmagick-script\fP \fIscript-file\fP [\fIscript-arguments\fP]... .SH OVERVIEW Use ImageMagick\[rg] to create, edit, compose, or convert bitmap images. It can read and write images in a variety of formats (over 200) including PNG, JPEG, GIF, HEIC, TIFF, DPX, EXR, WebP, Postscript, PDF, and SVG. Use ImageMagick to resize, flip, mirror, rotate, distort, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and B\['e]zier curves. The functionality of ImageMagick is typically utilized from the command-line. It can also be accessed from programs written in your favorite language using the corresponding interface: G2F (Ada), MagickCore (C), MagickWand (C), ChMagick (Ch), ImageMagickObject (COM+), Magick++ (C++), JMagick (Java), JuliaIO (Julia), L-Magick (Lisp), Lua (LuaJIT), NMagick (Neko/haXe), Magick.NET (.NET), PascalMagick (Pascal), ALImageMagick (Delphi), PerlMagick (Perl), MagickWand for PHP (PHP), IMagick (PHP), PythonMagick (Python), magick (R), RMagick (Ruby), or TclMagick (Tcl/TK). With a language interface, use ImageMagick to modify or create images dynamically and automagically. ImageMagick utilizes multiple computational threads to increase performance. It can read, process, or write mega-, giga-, or tera-pixel image sizes. ImageMagick is free software delivered as a ready-to-run binary distribution, or as source code that you may use, copy, modify, and distribute in both open and proprietary applications. It is distributed under a derived Apache 2.0 license. The ImageMagick development process ensures a stable API and ABI. Before each ImageMagick release, we perform a comprehensive security assessment that includes memory error, thread data race detection, and continuous fuzzing to help prevent security vulnerabilities. The current release is ImageMagick 7.0.8-11. It runs on Linux, Windows, macOS, iOS, Android OS, and others. We continue to maintain the legacy release of ImageMagick, version 6, at https://legacy.imagemagick.org. The authoritative ImageMagick web site is https://imagemagick.org. The authoritative source code repository is https://github.com/ImageMagick. We maintain a source code mirror at https://gitlab.com/ImageMagick. ImageMagick is a suite of command-line utilities for manipulating images. You may have edited images at one time or another using programs such as GIMP or Photoshop, which expose their functionality mainly through a graphical user interface. However, a GUI program is not always the right tool. Suppose you want to process an image dynamically from a web script, or you want to apply the same operations to many images, or repeat a specific operation at different times to the same or different image. For these types of operations, a command-line utility is more suitable. The remaining of this manpage is a list of the available command-line utilities and their short descriptions. For further documentation concerning a particular command and its options, consult the corresponding manpage. If you are just getting acquainted with ImageMagick, start at the top of that list, the magick(1) program, and work your way down. Also, make sure to check out Anthony Thyssen's tutorial on how to use ImageMagick utilities to convert, compose, or edit images from the command-line. .TP .B magick Read images into memory, perform operations on those images, and write them out to either the same or some other image file format. The "-script" option can be used to switch from processing command line options, to reading options from a file or pipeline. .TP .B magick-script This command is similar to magick(1) but with an implied "-script" option. It is useful in special "#!/usr/bin/env magick-script" scripts that search for the magick-script(1) command anywhere along the users PATH, rather than in a hardcoded command location. .TP .B convert Available for Backward compatibility with ImageMagick's version 6 convert(1). Essentially, it is just an alias to a restrictive form of the magick(1) command, which should be used instead. .TP .B mogrify Resize an image, blur, crop, despeckle, dither, draw on, flip, join, re-sample, and much more. This command overwrites the original image file, whereas convert(1) writes to a different image file. .TP .B identify Describe the format and characteristics of one or more image files. .TP .B composite Overlap one image over another. .TP .B montage Create a composite image by combining several separate ones. The images are tiled on the composite image, optionally adorned with a border, frame, image name, and more. .TP .B compare Mathematically and visually annotate the difference between an image and its reconstruction. .TP .B stream Stream one or more pixel components of the image or portion of the image to your choice of storage formats. It writes the pixel components as they are read from the input image, a row at a time, making stream(1) desirable when working with large images, or when you require raw pixel components. .TP .B display Display an image or image sequence on any X server. .TP .B animate Animate an image sequence on any X server. .TP .B import Save any visible window on any X server and output it as an image file. You can capture a single window, the entire screen, or any rectangular portion of the it. .TP .B conjure Interpret and execute scripts written in the Magick Scripting Language (MSL). .PP For more information about the ImageMagick, point your browser to file:///opt/alt/alt-ImageMagick/usr/share/doc/ImageMagick-7/index.html or https://imagemagick.org/. .SH SEE ALSO convert(1), compare(1), composite(1), conjure(1), identify(1), import(1), magick(1), magick-script(1), montage(1), display(1), animate(1), import(1), Magick++-config(1), MagickCore-config(1), MagickWand-config(1) .SH COPYRIGHT \fBCopyright (C) 1999 ImageMagick Studio LLC.

📄 cwebp.1 .\" Hey, EMACS: -- nroff -- .TH CWEBP 1 "April 10, 2025" .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 an image using the WebP format. Input format can be either PNG, JPEG, TIFF, WebP or raw Y'CbCr samples. Note: Animated PNG and WebP files are not supported. .SH OPTIONS The basic options are: .TP .BI \-o " string Specify the name of the output WebP file. If omitted, \fBcwebp\fP will perform compression but only report statistics. Using "\-" as output name will direct output to 'stdout'. .TP .BI \-\- " string Explicitly specify the input file. This option is useful if the input file starts with a '\-' for instance. This option must appear \fBlast\fP. Any other options afterward will be ignored. .TP .B \-h, \-help A short usage summary. .TP .B \-H, \-longhelp A summary of all the possible options. .TP .B \-version Print the version number (as major.minor.revision) and exit. .TP .B \-lossless Encode the image without any loss. For images with fully transparent area, the invisible pixel values (R/G/B or Y/U/V) will be preserved only if the \-exact option is used. .TP .BI \-near_lossless " int Specify the level of near\-lossless image preprocessing. This option adjusts pixel values to help compressibility, but has minimal impact on the visual quality. It triggers lossless compression mode automatically. The range is 0 (maximum preprocessing) to 100 (no preprocessing, the default). The typical value is around 60. Note that lossy with \fB\-q 100\fP can at times yield better results. .TP .BI \-q " float Specify the compression factor for RGB channels between 0 and 100. The default is 75. .br In case of lossy compression (default), a small factor produces a smaller file with lower quality. Best quality is achieved by using a value of 100. .br In case of lossless compression (specified by the \fB\-lossless\fP option), a small factor enables faster compression speed, but produces a larger file. Maximum compression is achieved by using a value of 100. .TP .BI \-z " int Switch on \fBlossless\fP compression mode with the specified level between 0 and 9, with level 0 being the fastest, 9 being the slowest. Fast mode produces larger file size than slower ones. A good default is \fB\-z 6\fP. This option is actually a shortcut for some predefined settings for quality and method. If options \fB\-q\fP or \fB\-m\fP are subsequently used, they will invalidate the effect of this option. .TP .BI \-alpha_q " int Specify the compression factor for alpha compression between 0 and 100. Lossless compression of alpha is achieved using a value of 100, while the lower values result in a lossy compression. The default is 100. .TP .BI \-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. Since \fB\-preset\fP overwrites the other parameters' values (except the \fB\-q\fP one), this option should preferably appear first in the order of the arguments. .TP .BI \-m " int Specify the compression method to use. This parameter controls the trade off 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 in faster processing time at the expense of larger file size and lower compression quality. .TP .BI \-crop " x_position y_position width height Crop the source to a rectangle with top\-left corner at coordinates (\fBx_position\fP, \fBy_position\fP) and size \fBwidth\fP x \fBheight\fP. This cropping area must be fully contained within the source rectangle. Note: the cropping is applied \fIbefore\fP any scaling. .TP .BI \-resize " width height Resize the source to a rectangle with size \fBwidth\fP x \fBheight\fP. If either (but not both) of the \fBwidth\fP or \fBheight\fP parameters is 0, the value will be calculated preserving the aspect\-ratio. Note: scaling is applied \fIafter\fP cropping. .TP .BI \-resize_mode " string Specify the behavior of the \fB\-resize\fP option. Possible values are: \fBdown_only\fP, \fBup_only\fP, \fBalways\fP (default). \fBdown_only\fP will use the values specified by \fB\-resize\fP if \fIeither\fP the input width or height are larger than the given dimensions. Similarly, \fBup_only\fP will only resize if \fIeither\fP the input width or height are smaller than the given dimensions. .TP .B \-mt Use multi\-threading for encoding, if possible. .TP .B \-low_memory Reduce memory usage of lossy encoding by saving four times the compressed size (typically). This will make the encoding slower and the output slightly different in size and distortion. This flag is only effective for methods 3 and up, and is off by default. Note that leaving this flag off will have some side effects on the bitstream: it forces certain bitstream features like number of partitions (forced to 1). Note that a more detailed report of bitstream size is printed by \fBcwebp\fP when using this option. .SS LOSSY OPTIONS These options are only effective when doing lossy encoding (the default, with or without alpha). .TP .BI \-size " int Specify a target size (in bytes) to try and reach for the compressed output. The compressor will make several passes of partial encoding in order to get as close as possible to this target. If both \fB\-size\fP and \fB\-psnr\fP are used, \fB\-size\fP value will prevail. .TP .BI \-psnr " float Specify a target PSNR (in dB) to try and reach for the compressed output. The compressor will make several passes of partial encoding in order to get as close as possible to this target. If both \fB\-size\fP and \fB\-psnr\fP are used, \fB\-size\fP value will prevail. .TP .BI \-pass " int Set a maximum number of passes to use during the dichotomy used by options \fB\-size\fP or \fB\-psnr\fP. Maximum value is 10, default is 1. If options \fB\-size\fP or \fB\-psnr\fP were used, but \fB\-pass\fP wasn't specified, a default value of '6' passes will be used. If \fB\-pass\fP is specified, but neither \fB-size\fP nor \fB-psnr\fP are, a target PSNR of 40dB will be used. .TP .BI \-qrange " int int Specifies the permissible interval for the quality factor. This is particularly useful when using multi-pass (\fB\-size\fP or \fB\-psnr\fP options). Default is 0 100. If the quality factor is outside this range, it will be clamped. If the minimum value must be less or equal to the maximum one. .TP .B \-af Turns auto\-filter on. This algorithm will spend additional time optimizing the filtering strength to reach a well\-balanced quality. .TP .B \-jpeg_like Change the internal parameter mapping to better match the expected size of JPEG compression. This flag will generally produce an output file of similar size to its JPEG equivalent (for the same \fB\-q\fP setting), but with less visual distortion. .TP Advanced options: .TP .BI \-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 value the smoother the picture will appear. Typical values are usually in the range of 20 to 50. .TP .BI \-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 strong filtering (if filtering is being used thanks to the \fB\-f\fP option). Strong filtering is on by default. .TP .B \-nostrong Disable strong filtering (if filtering is being used thanks to the \fB\-f\fP option) and use simple filtering instead. .TP .B \-sharp_yuv Use more accurate and sharper RGB->YUV conversion. Note that this process is slower than the default 'fast' RGB->YUV conversion. .TP .BI \-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 50. .TP .BI \-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. This option has no effect for methods 3 and up, unless \fB\-low_memory\fP is used. .TP .BI \-partition_limit " int Degrade quality by limiting the number of bits used by some macroblocks. Range is 0 (no degradation, the default) to 100 (full degradation). Useful values are usually around 30\-70 for moderately large images. In the VP8 format, the so\-called control partition has a limit of 512k and is used to store the following information: whether the macroblock is skipped, which segment it belongs to, whether it is coded as intra 4x4 or intra 16x16 mode, and finally the prediction modes to use for each of the sub\-blocks. For a very large image, 512k only leaves room for a few bits per 16x16 macroblock. The absolute minimum is 4 bits per macroblock. Skip, segment, and mode information can use up almost all these 4 bits (although the case is unlikely), which is problematic for very large images. The partition_limit factor controls how frequently the most bit\-costly mode (intra 4x4) will be used. This is useful in case the 512k limit is reached and the following message is displayed: \fIError code: 6 (PARTITION0_OVERFLOW: Partition #0 is too big to fit 512k)\fP. If using \fB\-partition_limit\fP is not enough to meet the 512k constraint, one should use less segments in order to save more header bits per macroblock. See the \fB\-segments\fP option. Note the \fB-m\fP and \fB-q\fP options also influence the encoder's decisions and ability to hit this limit. .SS LOGGING OPTIONS These options control the level of output: .TP .B \-v Print extra information (encoding time in particular). .TP .B \-print_psnr Compute and report average PSNR (Peak\-Signal\-To\-Noise ratio). .TP .B \-print_ssim Compute and report average SSIM (structural similarity metric, see https://en.wikipedia.org/wiki/SSIM for additional details). .TP .B \-print_lsim Compute and report local similarity metric (sum of lowest error amongst the collocated pixel neighbors). .TP .B \-progress Report encoding progress in percent. .TP .B \-quiet Do not print anything. .TP .B \-short Only print brief information (output file size and PSNR) for testing purposes. .TP .BI \-map " int Output additional ASCII\-map of encoding information. Possible map values range from 1 to 6. This is only meant to help debugging. .SS ADDITIONAL OPTIONS More advanced options are: .TP .BI \-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 .BI \-pre " int Specify some preprocessing steps. Using a value of '2' will trigger quality\-dependent pseudo\-random dithering during RGBA\->YUVA conversion (lossy compression only). .TP .BI \-alpha_filter " string Specify the predictive filtering method for the alpha plane. One of 'none', \&'fast' or 'best', in increasing complexity and slowness order. Default is \&'fast'. Internally, alpha filtering is performed using four possible predictions (none, horizontal, vertical, gradient). The 'best' mode will try each mode in turn and pick the one which gives the smaller size. The 'fast' mode will just try to form an a priori guess without testing all modes. .TP .BI \-alpha_method " int Specify the algorithm used for alpha compression: 0 or 1. Algorithm 0 denotes no compression, 1 uses WebP lossless format for compression. The default is 1. .TP .B \-exact Preserve RGB values in transparent area. The default is off, to help compressibility. .TP .BI \-blend_alpha " int This option blends the alpha channel (if present) with the source using the background color specified in hexadecimal as 0xrrggbb. The alpha channel is afterward reset to the opaque value 255. .TP .B \-noalpha Using this option will discard the alpha channel. .TP .BI \-hint " string Specify the hint about input image type. Possible values are: \fBphoto\fP, \fBpicture\fP or \fBgraph\fP. .TP .BI \-metadata " string A comma separated list of metadata to copy from the input to the output if present. Valid values: \fBall\fP, \fBnone\fP, \fBexif\fP, \fBicc\fP, \fBxmp\fP. The default is \fBnone\fP. Note: each input format may not support all combinations. .TP .B \-noasm Disable all assembly optimizations. .SH EXIT STATUS If there were no problems during execution, \fBcwebp\fP exits with the value of the C constant \fBEXIT_SUCCESS\fP. This is usually zero. .PP If an error occurs, \fBcwebp\fP exits with the value of the C constant \fBEXIT_FAILURE\fP. This is usually one. .SH EXAMPLES cwebp \-q 50 -lossless picture.png \-o picture_lossless.webp .br cwebp \-q 70 picture_with_alpha.png \-o picture_with_alpha.webp .br cwebp \-sns 70 \-f 50 \-size 60000 picture.png \-o picture.webp .br cwebp \-o picture.webp \-\- \-\-\-picture.png .SH AUTHORS \fBcwebp\fP is a part of libwebp and was written by the WebP team. .br The latest source tree is available at https://chromium.googlesource.com/webm/libwebp .PP This manual page was written by Pascal Massimino <pascal.massimino@gmail.com>, for the Debian project (and may be used by others). .SH REPORTING BUGS Please report all bugs to the issue tracker: https://issues.webmproject.org .br Patches welcome!

📄 dwebp.1 .\" Hey, EMACS: -- nroff -- .TH DWEBP 1 "July 18, 2024" .SH NAME dwebp \- decompress a WebP file to an image file .SH SYNOPSIS .B dwebp .RI [ options ] " input_file.webp .br .SH DESCRIPTION This manual page documents the .B dwebp command. .PP \fBdwebp\fP decompresses WebP files into PNG, PAM, PPM or PGM images. Note: Animated WebP files are not supported. .SH OPTIONS The basic options are: .TP .B \-h Print usage summary. .TP .B \-version Print the version number (as major.minor.revision) and exit. .TP .BI \-o " string Specify the name of the output file (as PNG format by default). Using "-" as output name will direct output to 'stdout'. .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 .B \-bmp Change the output format to uncompressed BMP. .TP .B \-tiff Change the output format to uncompressed TIFF. .TP .B \-pam Change the output format to PAM (retains alpha). .TP .B \-ppm Change the output format to PPM (discards alpha). .TP .B \-pgm Change the output format to PGM. The output consists of luma/chroma samples instead of RGB, using the IMC4 layout. This option is mainly for verification and debugging purposes. .TP .B \-yuv Change the output format to raw YUV. The output consists of luma/chroma-U/chroma-V samples instead of RGB, saved sequentially as individual planes. This option is mainly for verification and debugging purposes. .TP .B \-nofancy Don't use the fancy upscaler for YUV420. This may lead to jaggy edges (especially the red ones), but should be faster. .TP .B \-nofilter Don't use the in-loop filtering process even if it is required by the bitstream. This may produce visible blocks on the non-compliant output, but it will make the decoding faster. .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. .TP .BI \-alpha_dither If the compressed file contains a transparency plane that was quantized during compression, this flag will allow dithering the reconstructed plane in order to generate smoother transparency gradients. .TP .B \-nodither Disable all dithering (default). .TP .B \-mt Use multi-threading for decoding, if possible. .TP .BI \-crop " x_position y_position width height Crop the decoded picture to a rectangle with top-left corner at coordinates (\fBx_position\fP, \fBy_position\fP) and size \fBwidth\fP x \fBheight\fP. This cropping area must be fully contained within the source rectangle. The top-left corner will be snapped to even coordinates if needed. This option is meant to reduce the memory needed for cropping large images. Note: the cropping is applied \fIbefore\fP any scaling. .TP .B \-flip Flip decoded image vertically (can be useful for OpenGL textures for instance). .TP \fB\-resize\fR, \fB\-scale\fI width height\fR Rescale the decoded picture to dimension \fBwidth\fP x \fBheight\fP. This option is mostly intended to reducing the memory needed to decode large images, when only a small version is needed (thumbnail, preview, etc.). Note: scaling is applied \fIafter\fP cropping. If either (but not both) of the \fBwidth\fP or \fBheight\fP parameters is 0, the value will be calculated preserving the aspect-ratio. .TP .B \-quiet Do not print anything. .TP .B \-v Print extra information (decoding time in particular). .TP .B \-noasm Disable all assembly optimizations. .SH EXIT STATUS If there were no problems during execution, \fBdwebp\fP exits with the value of the C constant \fBEXIT_SUCCESS\fP.

📄 gif2webp.1 .\" Hey, EMACS: -- nroff -- .TH GIF2WEBP 1 "November 4, 2024" .SH NAME gif2webp \- Convert a GIF image to WebP .SH SYNOPSIS .B gif2webp .RI [ options ] " input_file.gif \-o output_file.webp .br .SH DESCRIPTION This manual page documents the .B gif2webp command. .PP \fBgif2webp\fP converts a GIF image to a WebP image. .SH OPTIONS The basic options are: .TP .BI \-o " string Specify the name of the output WebP file. If omitted, \fBgif2webp\fP will perform conversion but only report statistics. Using "\-" as output name will direct output to 'stdout'. .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 .B \-h, \-help Usage information. .TP .B \-version Print the version number (as major.minor.revision) and exit. .TP .B \-lossy Encode the image using lossy compression. .TP .B \-mixed Mixed compression mode: optimize compression of the image by picking either lossy or lossless compression for each frame heuristically. .TP .BI \-near_lossless " int Specify the level of near\-lossless image preprocessing. This option adjusts pixel values to help compressibility, but has minimal impact on the visual quality. It triggers lossless compression mode automatically. The range is 0 (maximum preprocessing) to 100 (no preprocessing, the default). The typical value is around 60. Note that lossy with \fB\-q 100\fP can at times yield better results. .TP .B \-sharp_yuv Use more accurate and sharper RGB->YUV conversion. Note that this process is slower than the default 'fast' RGB->YUV conversion. .TP .BI \-q " float Specify the compression factor for RGB channels between 0 and 100. The default is 75. .br In case of lossless compression (default), a small factor enables faster compression speed, but produces a larger file. Maximum compression is achieved by using a value of 100. .br In case of lossy compression (specified by the \-lossy option), a small factor produces a smaller file with lower quality. Best quality is achieved by using a value of 100. .TP .BI \-m " int Specify the compression method to use. This parameter controls the trade off 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 file size and lower compression quality. .TP .BI \-min_size Encode image to achieve smallest size. This disables key frame insertion and picks the dispose method resulting in the smallest output for each frame. It uses lossless compression by default, but can be combined with \-q, \-m, \-lossy or \-mixed options. .TP .BI \-kmin " int .TP .BI \-kmax " int Specify the minimum and maximum distance between consecutive key frames (independently decodable frames) in the output animation. The tool will insert some key frames into the output animation as needed so that this criteria is satisfied. .br A 'kmax' value of 0 will turn off insertion of key frames. A 'kmax' value of 1 will result in all frames being key frames. 'kmin' value is not taken into account in both these special cases. Typical values are in the range 3 to 30. Default values are kmin = 9, kmax = 17 for lossless compression and kmin = 3, kmax = 5 for lossy compression. .br These two options are relevant only for animated images with large number of frames (>50). .br When lower values are used, more frames will be converted to key frames. This may lead to smaller number of frames required to decode a frame on average, thereby improving the decoding performance. But this may lead to slightly bigger file sizes. Higher values may lead to worse decoding performance, but smaller file sizes. .br Some restrictions: .br (i) kmin < kmax, .br (ii) kmin >= kmax / 2 + 1 and .br (iii) kmax - kmin <= 30. .br If any of these restrictions are not met, they will be enforced automatically. .TP .BI \-metadata " string A comma separated list of metadata to copy from the input to the output if present. Valid values: \fBall\fP, \fBnone\fP, \fBicc\fP, \fBxmp\fP. The default is \fBxmp\fP. .TP .BI \-f " int For lossy encoding only (specified by the \-lossy option). 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 value the smoother the picture will appear. Typical values are usually in the range of 20 to 50. .TP .B \-mt Use multi-threading for encoding, if possible. .TP .B \-loop_compatibility If enabled, handle the loop information in a compatible fashion for Chrome version prior to M62 (inclusive) and Firefox. .TP .B \-v Print extra information. .TP .B \-quiet Do not print anything. .SH EXIT STATUS If there were no problems during execution, \fBgif2webp\fP exits with the value of the C constant \fBEXIT_SUCCESS\fP. This is usually zero. .PP If an error occurs, \fBgif2webp\fP exits with the value of the C constant \fBEXIT_FAILURE\fP.
