This is a standalone library, not a Runtime Android library. You need to use it BEFORE your Android compilation (and only once per SVG file). ## Why? I want to use a scalable image format. A SVG sounds really good but it's a bit long to load (mainly the time to parse the XML) and I didn't find any library that support the Hardware acceleration. ## How does it work? My main goal is to have a [Drawable](http://developer.android.com/reference/android/graphics/drawable/Drawable.html) class: * Made a fork of the [svg-android](https://code.google.com/p/svg-android/) library. * Replaced any instructions to create a [Picture](http://developer.android.com/reference/android/graphics/Picture.html) to collect them into a Logger. * Print this Logger. * Save it to a Drawable java class. ## How to use it? You can read the code but I'm not proud of it. I started to do a POC for a basic usage and now I need to transform the code to make it more readable and robust. You can simply use the [jar provided into this repo](https://github.com/StanKocken/SVG2Drawable/blob/master/svg_converter.jar) by specify: * the SVG file * the package where you want to put the Drawable * the drawable name You can also specify the output of the script to create a file. By adding "> filename.java". java -jar svg_converter.jar example.svg com.skocken.svg.example.drawable ExampleDrawable > ExampleDrawable.java Now, copy this "ExampleDrawable.java" into your Android project, into the package "com.skocken.svg.example.drawable" (from this example), and add it to your ImageView into your code with: imageview.setImageDrawable(new ExampleDrawable()); ![diagram](https://raw.githubusercontent.com/StanKocken/SVG2Drawable/master/svg_to_drawable.png) ## License * [Apache 2.0](http://www.apache.org/licenses/LICENSE-2.0.html) ## Contributing If you found a SVG with a problem, you can open an issue. Please, if possible, let me know if this same SVG work with the library [svg-android](https://code.google.com/p/svg-android/). Please fork this repository and contribute back using [pull requests](https://github.com/StanKocken/SVG2Drawable/pulls). Any contributions, large or small, major features, bug fixes, additional language translations, unit/integration tests are welcomed and appreciated but will be thoroughly reviewed and discussed. ================================================ FILE: build.xml ================================================ ================================================ FILE: src/com/skocken/svgconverter/Unparse.java ================================================ package com.skocken.svgconverter; import java.io.FileInputStream; import com.skocken.svgconverter.svg.SVGParser; public class Unparse { public static void main(String[] args) { if (args.length == 3) { try { SVGParser.getSVGFromInputStream(args[1], args[2], new FileInputStream(args[0])); } catch (Exception e) { e.printStackTrace(); } } else { System.out.println("Some paramaters are missing.
