Large Image Solution Pack Build Status

Introduction

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.

Requirements

This module requires the following modules/libraries:

For JP2 derivative generation, we require at least one of:

  • Kakadu (bundled with Djatoka)
  • Imagemagick with JPEG 2000 support

Installation

Install as usual, see this for further information.

Configuration

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.

Configuration

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. If the executable resides elsewhere on the server and no soft link has been created, be sure to provide the full path to the executable on the configuration page. 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.
