MAGE Image Plugin

The MAGE Image plugin will ensure that all images clients attach to observations are rotated properly according to the image EXIF data. The plugin will also create thumbnails of configured sizes for each image attachment. MAGE clients will attempt to pull the smaller thumbnail images for certain views based on the client's view size and resolution. Enabling this plugin is optional.

Configuration

The image plugin utilizes the basic plugin state repository that core MAGE Service provides to store its configuration. The configuration document is fairly simple, and looks like

{
  enabled: false,
  intervalSeconds: 60,
  intervalBatchSize: 10,
  thumbnailSizes: [ 150, 320, 800, 1024, 2048 ],
}
