require('imagemin');\nconst imageminGiflossy = require('imagemin-giflossy');\n\nimagemin(['images/*.gif'], 'build/images', {use: [imageminGiflossy({lossy: 80})]}).then(() => {\n\tconsole.log('Images optimized');\n});\n```\n\n\n## API\n\n### imageminGiflossy([options])(buffer)\n\nReturns a promise for a buffer.\n\n#### options\n\n##### interlaced\n\nType: `boolean`
\nDefault: `false`\n\nInterlace gif for progressive rendering.\n\n##### optimizationLevel\n\nType: `number`
\nDefault: `1`\n\nSelect an optimization level between `1` and `3`.\n\n> The optimization level determines how much optimization is done; higher levels take longer, but may have better results.\n\n1. Stores only the changed portion of each image.\n2. Also uses transparency to shrink the file further.\n3. Try several optimization methods (usually slower, sometimes better results)\n\n##### colors\n\nType: `number`\n\nReduce the number of distinct colors in each output GIF to num or less. Num must be between 2 and 256.\n\n##### lossy\n\nType: `Number` \nDefault: `undefined`\n\nOrder pixel patterns to create smaller GIFs at cost of artifacts and noise.\n\nAdjust lossy argument to quality you want (30 is very light compression, 200 is heavy).\n\nIt works best when only little loss is introduced, and due to limitation of the compression algorithm very high loss levels won't give as much gain.\n\ne.g.:\n```js\nimageminGiflossy({ lossy: 80 });\n```\n\n##### resize\n\nType: `string` \nDefault: `undefined`\n\nResize the output GIF to *widthxheight*.\n\ne.g.:\n```js\nimageminGiflossy({ resize: '300x200' });\n```\n\n##### noLogicalScreen\n\nType: `boolean` \nDefault: `false`\n\nSets the output logical screen to the size of the largest output frame.\n\ne.g.:\n```js\nimageminGiflossy({ noLogicalScreen: true });\n```\n\n##### resizeMethod\n\nType: `string` \nDefault: `mix`\n\nSet the method used to resize images.\n\ne.g.:\n```js\nimageminGiflossy({ resizeMethod: 'sample' });\n```\n\n##### colorMethod\n\nType: `string` \nDefault: `diversity`\n\nDetermine how a smaller colormap is chosen.\n\ne.g.:\n```js\nimageminGiflossy({ colorMethod: 'blend-diversity' });\n```\n\n##### optimize\n\nType: `string` \nDefault: `1`\n\nOptimize output GIF animations for space.\n\nThere are currently three levels:\n * `1`: Stores only the changed portion of each image. This is the default.\n * `2`: Also uses transparency to shrink the file further.\n * `3`: Try several optimization methods (usually slower, sometimes better results).\n\nOther optimization flags provide finer-grained control.\n\n * `keep-empty`: Preserve empty transparent frames (they are dropped by default).\n\ne.g.:\n```js\nimageminGiflossy({ optimize: '3' });\n```\n\n##### unoptimize\n\nType: `boolean` \nDefault: `false`\n\nUnoptimize GIF animations into an easy-to-edit form.\n\ne.g.:\n```js\nimageminGiflossy({ unoptimize: true });\n```\n\n#### buffer\n\nType: `buffer`\n\nBuffer to optimize.\n\n## License\n\nMIT © [imagemin](https://github.com/imagemin)\n","maintainers":[{"name":"jihchi","email":"achi@987.tw"}],"time":{"modified":"2022-06-19T00:37:17.288Z","created":"2016-02-25T15:06:17.874Z","1.0.0-rc1":"2016-02-25T15:06:17.874Z","1.0.0-rc2":"2016-02-26T15:47:39.294Z","5.0.0":"2016-06-23T11:08:45.903Z","5.1.0-1":"2016-06-24T02:36:40.163Z","5.1.0-2":"2016-06-24T02:46:04.478Z","5.1.10":"2016-10-27T10:15:42.936Z"},"homepage":"https://github.com/jihchi/imagemin-giflossy#readme","keywords":["compress","gif","giflossy","gulpplugin","image","imageminplugin","img","minify","optimize"],"repository":{"type":"git","url":"git+https://github.com/jihchi/imagemin-giflossy.git"},"author":{"name":"Jih-Chi Lee","email":"achi@987.tw","url":"github.com/jihchi"},"bugs":{"url":"https://github.com/jihchi/imagemin-giflossy/issues"},"license":"MIT","readmeFilename":"readme.md","users":{"mjankowski":true}}
