skal 65b99f1c92 add a -z option to cwebp, and WebPConfigLosslessPreset() function ... These are presets for lossless coding, similar to zlib. The shortcut for lossless coding is now, e.g.: cwebp -z 5 in.png -o out_lossless.webp There are 10 possible values for -z parameter: 0 (fastest, lowest compression) to 9 (slowest, best compression) A reasonable tradeoff is -z 6, e.g. -z 9 can be quite slow, so use with care. This -z option is just a shortcut for some pre-defined '-lossless -m xx -q yy' combinations. Change-Id: I6ae716456456aea065469c916c2d5ca4d6c6cf04		2014-03-11 23:25:35 +01:00
