Islandora 7.x-1.0 (Beta)
This documentation covers the latest release of Islandora 7.x.
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, and also supports the installation of image viewers that can accommodate the larger resolution.
This module requires the following modules/libraries:
To successfully create derivative data streams, ImageMagick (for TN & JPG) and Kakadu (for JP2) need to be installed on the server.
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_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:

The Large Image Solution Pack module's configuration page can be found at http://path.to.your.site/admin/islandora/solution_pack_config/large_image, and contains the following settings:
If no viewers are installed, the Large Image Solution Pack module will use its standard viewer to display images. For better results, the Open Seadragon library can be installed; check that page for further instructions. If it is installed, it can be selected here.
The Large Image Solution Pack comes with the following objects in http://path.to.your.site/admin/islandora/solution_pack_config/solution_packs:
An image ingested using the Large Image Solution Pack's content model using ImageMagick will have the following datastreams:
Default Fedora relationship metadata
MODS record filled out during ingest
Dublin Core record
Original TIFF or JP2 file uploaded
|JP2||JPEG 2000 derivative created by ImageMagick or Kakadu|
|JPG||Medium-sized JPEG created by ImageMagick and used in the standard image viewer|
|TN||Thumbnail icon created from the image during the ingest process|
The Large Image Solution Pack comes with the Large image MODS form.
