+# **Data Pixels**
+
+## **Create Pixel Art Programmatically**
+The **DataPixels.js** source code facilitates production of pixel art that is entirely generated programmatically at runtime.   Additionally, the accompanying desktop application, **Data Pixels Playground**, may be used to write and execute code for displaying both customized and automated pixel art.
+
+## **DataPixels.js** 
+
+The DataPixels.js source code features a modular, ES2015 Class design for accessible and effortless construction of new instances.  Each instance contains both **HTMLCanvasElement** and **HTMLImageElement** public accessors whose sources consist of the programmatically generated pixel art.
+
+The DataPixels.js constructor requires 2 arguments:
+
+1. **pixelData**:  An array containing one or more arrays of equal length, consisting of strings composed of 0-255 integer values per 24-bit RGB color channel (e.g., `“255, 255, 255”`) or 32-bit RGBA color channel (e.g., `“255, 255, 255, 255”`).  Additionally, the strings may optionally contain any kind of descriptive text (e.g., `“Red: 255, G - 128, 64 for Blue, Transparency = 32”`) as only the number values within the string will be parsed in RGB / RGBA order.  Strings that contain more than 4 numbers will throw an error.
+
+2. **pixelSize**:  The size of each color data unit in pixels.  This value represents the size of each perceived pixel that forms the pixel art.
+

+
+## **Data Pixels Playground**
+Data Pixels Playground is a lightweight, cross-platform, desktop application for **Windows**, **Mac** and **Linux**, which may be used to write and execute DataPixels.js instances for previewing and testing purposes.
+
+The application features **built-in example code** via the *Help* menu as well as the ability to **parse pixel data from image files** to produce automatically generated code through the *File > Open Image File…* menu item or through drag-and-drop gestures.
+
+Note: pixel color values that are automatically interpreted from image files with an embedded color space may differ slightly from the image’s intended color values.

+
+## **Desktop Application Release Builds**
+Creating release builds for **Windows**, **Mac** and/or **Linux** is a 2-step process: code compilation, then application packaging, both of which are accomplished by running command-line NPM scripts that execute Gulp tasks.
+
+#### **Compilation**
+
+Production code compilation can be executed by entering the following CLI command at the project **root folder** [*~/DataPixels/* ]:
+
+```
+npm run prod
+```
+
+For more detailed information concerning code compilation please refer to [**Project Foundation**](https://github.com/gmattie/Project-Foundation).
+
+#### **Packaging**
+
+Application packaging can be executed for either all or individual deployment targets by entering one of the following CLI commands at the project **build folder** [*~/DataPixels/resources/build/* ]:
+
+```
+npm run package
+```
+
+```
+npm run package-linux
+```
+
+```
+npm run package-mac
+```
+
+```
+npm run package-windows
+```
+
+Note: In order to avoid problems with code signing and other build issues it is highly recommended to execute packaging scripts for an individual platform from its own operating system.
+
+For more detailed information concerning application packaging please refer to [**Electron Packager**](https://github.com/electron-userland/electron-packager).
