imageopti

Wrapper for misc. image processors

imageopti


Wrapper for miscellaneous linux image utilities.

Implemented at the moment are jpegtran, jpegoptim, pngquant, pngout and imagemagick resize.

Or alternatively use smushit,

var opti = require('path/to/imageopti');

var vow = opti(file or dir [, [options]])

options:

    {
        //png: 'optipng', // str
        png: ['pngquant', 'optipng'], //or array
        jpg: 'jpegtran', //or jpegoptim, or both as an array
        ,destDir: '' //where to save the modified files, falsy is replace
        // recurse: true,
        // resize: {w: 100, h: 100}
        // ,smushit: true //if true all processing goes through smushit
        ,quality: 50 //for jpegoptim only
        ,min: 60, max: 80 //for pngquant
        ,colors: 256 //for pngquant
        ,concurrent: 1 //number of concurrent processes
        //if concurrent is falsy everything will be async
        ,verbose: true 
    };

The returned vow promises an object such as:

{ log: [list of messages describing what happened],
  size: { original: 437851, current: 437851 },
  savings: 0 }
