📏  Resizing...
❌  { Error: Command failed: gm convert: Unable to open file (/Users/chrisheninger/.nvm/versions/node/v7.10.0/lib/node_modules/icon-magic/.tmp/apple-touch-icon-167x167.png) [No such file or directory].

Need to figure out how to properly create a .tmp directory to write the resize files to, and then need to make sure the icons directory ends up wherever the user executes the script from. (and make sure not to clobber an existing directory with the same name)

Until then, cloning this repo and running npm start ./sample.png should work.

• Might as well generate a favicon (32x32) png while we're at it

Make available and executable via npm install image-magic followed by image-magic ./path/to/source.png, which would then output an icons directory wherever it was executed from.

Apple dictates the web app icons shouldn't have rounded corners– they will automatically do this in their UI.

• Update sample png
• Document this in readme

Android has some rules too I think- something with dynamic icons?

• Research this
• Do things

• Quick explanation with links
• Instructions

• Source image must be a png
• Source image must be a square
• Source image must be greater than or equal to 512x512

Think this should be sufficient.

Build a GUI that is basically https://github.com/imagemin/imagemin-app

• Electron + CRApp initial setup facebook/create-react-app#1718
• Figure out why the release-build app won't load– development works OK
• Implement react-dropzone (familiar+great library)
• Figure out how to get the dropzone callback function to run the node icon-magic.js script with the dropped PNG as the argument
