# Iconizer shell script by Steve Richey (srichey@floatlearning.com)
# Modified by Rich Ellis (rich@richellis.net) based on contributions on Github from crishoj, giria

#
# This is a simple tool to generate all necessary app icon sizes and the JSON file for an *EXISTING* Xcode project from one file.
# To use: specify the path to your vector graphic (PDF format) and the path to your Xcode folder containing Images.xcassets
# Example: sh iconizer.sh MyVectorGraphic.pdf MyXcodeProject
#
# Requires ImageMagick: http://www.imagemagick.org/
# Requires GhostScript: http://www.ghostscript.com/
#
# Install dependencies with Homebrew: http://brew.sh/
# brew install imagemagick
# brew install ghostscript
# Exit on first error
