## Instructions for Generating and Viewing Masked PPM files

Generate a new Masked PPM file ("output.ppm"), taking an image to mask
("image.ppm") and an image mask ("mask.pbm") as inputs.

A. Generate the masked PPM image to view.

1. Open a terminal, navigate to your mask-ppm checkout, then type:

```bash
bash mask.sh image.ppm mask.pbm > output.ppm
```

B. View the generated PPM image using command line tools.

NOTE: These instructions assume a [MacOS](http://www.apple.com/macos/)
10.11+ environment with [Homebrew](http://brew.sh/index.html).

1. Install a netpbm compatible image viewer (e.g.
[GraphicsMagick](http://www.graphicsmagick.org/)).

```bash
brew cask install xquartz
brew install graphicsmagick --with-x11
```

2. Run [XQuartz](https://www.xquartz.org/) from
Applications/Utilities/XQuartz and set the DISPLAY variable.

```bash
export DISPLAY=:0
```

3. Use the 'display' application from GraphicsMagick to view the image
output.

```bash
gm display output.ppm
```

C. Vew the generated PPM image using online tools.

1. Open your favorite web browser (e.g.
[Google Chrome](https://www.google.com/chrome/)) and visit
[Netpbm Viewer](http://paulcuth.me.uk/netpbm-viewer).

2. Drag-and-drop your output file ("output.ppm") into the web browser;
specifically, taking care to drop it in the box labeled "Drag netpbm files
here."
