The Upscale Window can be used when working with a source image that is larger than the screen size.  It provides the ability to reproduce effects that were performed on a down-scaled source image in the main Liquib window, but at the resolution and quality of the original source image.  Thus, in the main Liquib screen you can conveniently and efficiently apply Tool and Effect manipulations on an image scaled down to fit within the screen.  Then, when a pleasing picture develops, use the Upscale Window to re-create and display the effect at the scale of the original source image.  The position, size and other parameters of Tools and Effects are adjusted up to match the source image dimensions.  The Upscale Window display can be scrolled horizontally and vertically to bring different portions of the image into view.  The Sync Update button can be pressed to bring the Upscale Window display up to date with the main Liquib screen.  Use the As button to save the upscaled Image or Tile.  The Sp button accesses the Save With Special Options screen, which provides additional choices for saving images at Full-Scale.  The Copy button stores the upscaled Image or Tile (if applicable) onto the clipboard so that it can be easily pasted into other graphics programs.
