Overview

The Large Image Solution Pack module supports ingesting and viewing TIF/TIFF files, which by nature tend to be extremely large in both filesize and resolution. The module supports creation of derivatives for use when a smaller filesize is necessary, and also supports the installation of image viewers that can accommodate the larger resolution.

Release Notes and Downloads

Configuration

The Large Image Solution Pack module's configuration page can be found at http://path.to.your.site/admin/islandora/large_image, and contains the following settings:

  • Lossless Derivative Creation?: Enabling this will force the Large Image Solution Pack to use no compression when creating derivatives.
  • Use Kakadu for Image Compression?: The Kakadu software suite can be installed on your server to take advantage of its much faster kdu_compress program. Check the official website at http://www.kakadusoftware.com/ for download and installation instructions

Viewers

If no viewers are installed, the Large Image Solution Pack module will use its standard viewer to display images. For better results, the OpenSeadragon library can be installed; check that page for further instructions. If it is installed, it can be selected here.
