The large image solution pack loads all required Fedora objects and creates an empty collection object to accept TIFFs and create derivatives.
This module requires teh 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
and kdu_expand
are 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
.
