The Large Image Solution Pack loads all required Fedora objects and creates an empty collection object to accept TIFFs and JPEG2000s (JP2) and create derivatives.

This module requires the following modules/libraries:

• Islandora
• Tuque
• ImageMagick
• Kakadu (bundled with Djatoka)

To successfully create derivative data streams, ImageMagick (for TN & JPG) and Kakadu (for JP2) need to be installed on the server.

Install as usual, see this for further information.

Configure the image-toolkit to use ImageMagick rather than GD in Administration > Configuration > Media > Image Toolkit (admin/config/media/image-toolkit). If GD is selected, TN and JPG datastreams will not be generated.

Select configuration options and viewer in Administration > Islandora > Large Image Collection (admin/islandora/large_image).

To use Kakadu, make sure that kdu_compress is available to the Apache user. Often users will create symbolic links from /usr/local/bin/kdu_compress to their installation of Kakadu that comes bundled with Adore-Djatoka. Make sure that the required dynamic libraries that come with Kakadu are accessible to kdu_compress and kdu_expand. If they are not present, attempting to run either command from the terminal will inform you that the libraries are missing. You can also use a symbolic link from /usr/local/lib to include these libraries. Remember to restart the terminal so your changes take affect. Also, make sure the php settings allow for enough memory and upload size: upload_max_filesize, post_max_size and memory_limit.
