\r\n\r\n**Octree Algorithm**\r\n\r\n![](\"https://raw.githubusercontent.com/benjaminadk/gif-encoder-2/master/examples/output/intermediate-octree.gif\")
\r\n\r\n## Algorithms\r\n\r\n- _NeuQuant_ tends to perform faster than _Octree_\r\n- _Octree_ tends to output a smaller file than _NeuQuant_\r\n- _Octree_ produces a slight banding effect\r\n\r\nThe example above encodes 20 images measuring 300px x 240px. The output file from _NeuQuant_ is 1172KB and the _Octree_ is less than half of that at 515KB.\r\n\r\n## Optimizer\r\n\r\nThe optimizer works by reusing the color palette from the previous image on the current image. This can reduce the overall processing time signifigantly but its best suited for a sequence of similarly colored images. Use the `setThreshold` method to set a percentage determining how similar the two images must be to trigger the optimizer. The default is `90%`. The optimizer is only used if `true` is passed as the 4th argument to the constructor.\r\n\r\n## Progress Event\r\n\r\nWorks if `totalFrames` is expressed in constructor, otherwise this value will be 0.\r\n\r\n```javascript\r\nencoder.on('progress', percent => {\r\n // do something with percent value\r\n})\r\n```\r\n","readmeFilename":"README.md"}
