Gradient Image Generator

This plugin provides an Expression Function called linearGradientImage() for generating simple, linear gradient PNG images based on the colors, distribution ratios, and dimensions you specify. The genesis for this plugin was to provide gradient color backgrounds for a Billboard Layout component’s backgroundMedia value. A companion Appian Application is distributed with the plugin (when downloaded from the App Market page) that includes Expression Rules and Interfaces for easy configuration of Billboard Layouts using this plugin, along with detailed documentation. Note that this companion application requires the Color Picker Component plugin, also available on the App Market.
