    Usage

    const imagemin = require('imagemin');
    const imageminGiflossy = require('imagemin-giflossy');
     
    imagemin(['images/*.gif'], 'build/images', {use: [imageminGiflossy({lossy: 80})]}).then(() => {
        console.log('Images optimized');
    });

    API

    imageminGiflossy([options])(buffer)

    Returns a promise for a buffer.

    options

    interlaced

    Type: boolean
    Default: false

    Interlace gif for progressive rendering.

    optimizationLevel

    Type: number
    Default: 1

    Select an optimization level between 1 and 3.

    The optimization level determines how much optimization is done; higher levels take longer, but may have better results.

    1. Stores only the changed portion of each image.
    2. Also uses transparency to shrink the file further.
    3. Try several optimization methods (usually slower, sometimes better results)
    colors

    Type: number

    Reduce the number of distinct colors in each output GIF to num or less. Num must be between 2 and 256.

    lossy

    Type: Number
    Default: undefined

    Order pixel patterns to create smaller GIFs at cost of artifacts and noise.

    Adjust lossy argument to quality you want (30 is very light compression, 200 is heavy).

    It 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.

    e.g.:

    imageminGiflossy({ lossy: 80 });
    resize

    Type: string
    Default: undefined

    Resize the output GIF to widthxheight.

    e.g.:

    imageminGiflossy({ resize: '300x200' });
    noLogicalScreen

    Type: boolean
    Default: false

    Sets the output logical screen to the size of the largest output frame.

    e.g.:

    imageminGiflossy({ noLogicalScreen: true });
    resizeMethod

    Type: string
    Default: mix

    Set the method used to resize images.

    e.g.:

    imageminGiflossy({ resizeMethod: 'sample' });
    colorMethod

    Type: string
    Default: diversity

    Determine how a smaller colormap is chosen.

    e.g.:

    imageminGiflossy({ colorMethod: 'blend-diversity' });
    optimize

    Type: string
    Default: 1

    Optimize output GIF animations for space.

    There are currently three levels:

    • 1: Stores only the changed portion of each image. This is the default.
    • 2: Also uses transparency to shrink the file further.
    • 3: Try several optimization methods (usually slower, sometimes better results).

    Other optimization flags provide finer-grained control.

    • keep-empty: Preserve empty transparent frames (they are dropped by default).

    e.g.:

    imageminGiflossy({ optimize: '3' });
    unoptimize

    Type: boolean
    Default: false

    Unoptimize GIF animations into an easy-to-edit form.

    e.g.:

    imageminGiflossy({ unoptimize: true });

    buffer

    Type: buffer

    Buffer to optimize.
