Requirements

• Ruby
• nokogiri gem
• osx-plist gem
• ImageMagick with SVG delegate library

Usage

Running generate.rb will generate all image files in three steps:

1. Create individual SVG files of each country map
2. Create PNG versions (optionally with a 2x resolution version) of each country map
3. Trims each PNG to the size of the country and outputs the pixel offset and dimensions to a property list file

The script takes a little while to complete, so you may wish to modify the process using these command-line flags:

• --no-generate-svg skips step 1
• --no-generate-png skips step 2
• --no-trim skips step 3
• --generate-2x generates an extra set of PNG files with an "@2x" suffix

Sample Output

The script will generate the following files for a given country, in this case, Canada (ca).

• countries/svg/ca.svg
• countries/png/ca.png

With the --generate-2x flag, this file is also generated:

• countries/png/ca@2x.png

The script also outputs a summary of the processed data:

• countries/countries.txt - a list of all country codes which had map images produced

• countries/countries_geometry.plist - a dictionary of country geometry info using the country code as keys

  The geometry info is represented as a dictionary, the keys being the resolution (1 or 2) of the map, and the values being a string representation of a CGRect.

    <key>ca</key>
    <dict>
    	<key>1</key>
    	<string>{{+102,+35},{211,100}}</string>
    	<key>2</key>
    	<string>{{+204,+70},{421,200}}</string>
    </dict>
