// ai2html is a script for Adobe Illustrator that converts your Illustrator document into html and css.
// Copyright (c) 2011-2018 The New York Times Company
// Licensed under the Apache License, Version 2.0 (the "License");
// you may not use this library except in compliance with the License.
// You may obtain a copy of the License at
// http://www.apache.org/licenses/LICENSE-2.0

// WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.
// See the License for the specific language governing permissions and
// limitations under the License.
// =====================================
// How to install ai2html
// =====================================
// - Move the ai2html.js file into the Illustrator folder where scripts are located.
// - For example, on Mac OS X running Adobe Illustrator CC 2014, the path would be: // Adobe Illustrator CC 2014/Presets/en_US/Scripts/ai2html.jsx
// =====================================
// How to use ai2html
// =====================================
// - Create your Illustrator artwork.
// - Size the artboard to the dimensions that you want the div to appear on the web page.
// - Make sure your Document Color Mode is set to RGB.
// - Use Arial or Georgia unless you have added your own fonts to the fonts array in the script.
// - Run the script by choosing: File > Scripts > ai2html
// - Go to the folder containing your Illustrator file. Inside will be a folder called ai2html-output.
// - Open the html files in your browser to preview your output.
function main() {
// Enclosing scripts in a named function (and not an anonymous, self-executing
// function) has been recommended as a way to minimise intermittent "MRAP" errors.
// (This advice may be superstitious, need more evidence to decide.)
// See (for example) https://forums.adobe.com/thread/1810764 and
// http://wwwimages.adobe.com/content/dam/Adobe/en/devnet/pdf/illustrator/scripting/Readme.txt
// How to update the version number:
// - Increment middle digit for new functionality or breaking changes
// or increment final digit for simple bug fixes or other minor changes.
// - Update the version number in package.json
// - Add an entry to CHANGELOG.md
// - Run 'npm publish' to create a new GitHub release
