| Usage: | ||
| cwebp [-preset <...>] [options] in_file [-o out_file] | ||
| If input size (-s) for an image is not specified, it is assumed to be a PNG, JPEG or TIFF file. | ||
| options: | ||
| -h / -help ............ short help | ||
| -H / -longhelp ........ long help | ||
| -q <float> ............. quality factor (0:small..100:big) | ||
| -alpha_q <int> ......... Transparency-compression quality (0..100). | ||
| -preset <string> ....... Preset setting, one of: | ||
| default, photo, picture, | ||
| drawing, icon, text | ||
| -preset must come first, as it overwrites other parameters. -z <int> ............... Activates lossless preset with given level in [0:fast, ..., 9:slowest] | ||
| -m <int> ............... compression method (0=fast, 6=slowest) | ||
| -segments <int> ........ number of segments to use (1..4) | ||
| -size <int> ............ Target size (in bytes) | ||
| -psnr <float> .......... Target PSNR (in dB. typically: 42) | ||
| -s <int> <int> ......... Input size (width x height) for YUV | ||
| -sns <int> ............. Spatial Noise Shaping (0:off, 100:max) | ||
| -f <int> ............... filter strength (0=off..100) | ||
| -sharpness <int> ....... filter sharpness (0:most .. 7:least sharp) | ||
| -strong ................ use strong filter instead of simple (default). | ||
| -nostrong .............. use simple filter instead of strong. | ||
| -partition_limit <int> . limit quality to fit the 512k limit on | ||
| the first partition (0=no degradation ... 100=full) | ||
| -pass <int> ............ analysis pass number (1..10) | ||
| -crop <x> <y> <w> <h> .. crop picture with the given rectangle | ||
| -resize <w> <h> ........ resize picture (after any cropping) | ||
| -mt .................... use multi-threading if available | ||
| -low_memory ............ reduce memory usage (slower encoding) | ||
| -map <int> ............. print map of extra info. | ||
| -print_psnr ............ prints averaged PSNR distortion. | ||
| -print_ssim ............ prints averaged SSIM distortion. | ||
| -print_lsim ............ prints local-similarity distortion. | ||
| -d <file.pgm> .......... dump the compressed output (PGM file). | ||
| -alpha_method <int> .... Transparency-compression method (0..1) | ||
| -alpha_filter <string> . predictive filtering for alpha plane. | ||
| One of: none, fast (default) or best. | ||
| -alpha_cleanup ......... Clean RGB values in transparent area. | ||
| -blend_alpha <hex> ..... Blend colors against background color | ||
| expressed as RGB values written in | ||
| hexadecimal, e.g. 0xc0e0d0 for red=0xc0 | ||
| green=0xe0 and blue=0xd0. | ||
| -noalpha ............... discard any transparency information. | ||
| -lossless .............. Encode image losslessly. | ||
| -hint <string> ......... Specify image characteristics hint. | ||
| One of: photo, picture or graph | ||
| -metadata <string> ..... comma separated list of metadata to | ||
| copy from the input to the output if present. | ||
| Valid values: all, none (default), exif, icc, xmp | ||
| -short ................. condense printed message | ||
| -quiet ................. don't print anything. | ||
| -version ............... print version number and exit. | ||
| -noasm ................. disable all assembly optimizations. | ||
| -v ..................... verbose, e.g. print encoding/decoding times | ||
| -progress .............. report encoding progress | ||
| Experimental Options: | ||
| -jpeg_like ............. Roughly match expected JPEG size. | ||
| -af .................... auto-adjust filter strength. | ||
| -pre <int> ............. pre-processing filter | ||
