blender

Blender is tool for converting media assets from svg format to png format in a specified array of sizes. This module is perfect for genreating icons to be used on a variety of screen sizes. Output folder structure, output sizes, icon types, and output icon names can be configured via a JSON object input.

Usage

You can use blender either via command line or as a node library.

Command line

$ npm install -g blender
$ ulimit -n 2048

To convert assets:

blender input output --config --size [platform(s)]

example uses: 
	blender ./input/svg ./output --config ./config.json --size 30 android api
	blender ./input/svg ./output --config ./config.json all
	blender ./input/svg ./output --size 30 

Command Line Documentation

input: 				relative path to folder
output: 			relative path to folder, will create if does not exist
--config: 		relative path to config file [optional, default: ./config.json]
--size: 			desired 1X size of generated PNG (e.g. --size 18 would yield a png of longest dimension 36 with scale factor of 2) [optional, default: 18]
platforms:		space delimited list of standardized platforms to generate png's for [optional, default: all]

Library

$ npm install blender --save-dev
$ ulimit -n 2048

Example:

blender = require 'blender'

var config = { 
  "formats": [
    {
      "name": "android",
      "sizes": [
        { "sizeDirectory" : "mdpi", "scale": 1 },
        { "sizeDirectory" : "hdpi",   "scale": 1.5 }
      ]
    },
    {
      "name": "ios",
      "sizes": [
        { "scale": 1 },
        { "scale": 2, "suffix": "@2x" }
      ]
    },
    {
      "name": "api",
      "sizes": [
        { "constant": 60, "suffix": "_60" },
        { "constant": 120, "suffix": "_120"}
      ], 
      "ignoreTypeSuffix": true
    }
  ]
}

blender.convert("./input/svg", "./output", config, 18, 'all', function() {
	console.log('done');
});

About the config JSON object:

  • = optional input

config: { formats }

formats: [ { name, *ignoreTypeSuffix, sizes } ]

-------- name: e.g. ios

-------- ignoreSuffixType: (default: false) if true, output icon names will not include typeSuffix

-------- sizes: [ { *scale, *constant, *suffix, *sizeDirectory } ]

---------------- scale: (default: 1.0) scale of output image

---------------- constant: (default none) set a constant size for output image

---------------- suffix: (default: none) suffix for renaming related to size (e.g. @2x)

---------------- sizeDirectory: (default: none) e.g. mdpi
