Summary

  Provides the user with a quick and efficient way of viewing mosaics even on memory limited machines. Currently allows the functionalities of zooming, panning, channel manipulation, and saving. More features and a spiffier interface will be provided in the near future.

Usage

 Upon choosing METiled Display from the ImageJ plugins menu, you will be promptedto open an image for viewing. While METiled Display can display regular TIFF files, it's true purpose is to open up tiled tiffs. Tiled tiffs provide the benefits of memory efficiency by separating a TIFF into spatial tiles so that the tiles can be loaded on demand. Therefore, unlike regular tiffs, tiled tiffs do not need to be completely loaded into memory for manipulation, and this allows even memory limited machines to manipulate these files.
 Unfortunately not many image processing software support this format including ImageJ and Photoshop. To work-around this problem, METiled Display now allows the ability to save images in a normal tiff format.
