Image Transformer

Description:

The Image Transformer provides a simple way to transform relatively small numbers of image files from one format to another.

Note that the ImageMagick service must be deployed prior to using the Image Transformer

Configuration Options:

1. Source Space: DuraCloud space where source image files are stored
2. Destination Space: DuraCloud space where transformed image files will be placed, along with a file which details the results of the conversion process
3. Destination Format: The image format to which the source files will be transformed
4. Destination Color Space: The colorspace of the transformed files, either "Source Image Color Space", meaning that the colorspace of the original image will be used, or sRGB, meaning that the colorspace will be transformed to sRGB.
5. Source file name prefix: Only files beginning with the value provided here will be transformed. For example, if you enter ABC, only files whose names begin with the string ABC will be processed. This field is optional.
6. Source file name suffix: Only files ending with the value provided here will be transformed. For example, you enter .jpg, only files whose names ends with the string .jpg will be processed. This field is optional.

Service Output
All outputs of this service are placed in the system space, x-service-out.

Image Transformer - Bulk

Description:

The Bulk Image Transformer provides a simple way to transform image files from one format to another in bulk. This service uses Amazon's Elastic Map Reduce capability to run the image transformation task within a Hadoop cluster.

Configuration Options:

1. Source Space: DuraCloud space where source image files are stored
2. Destination Space: DuraCloud space where transformed image files will be placed, along with a file which details the results of the transformation process
3. Destination Format: The image format to which the source files will be transformed
4. Destination Color Space: The colorspace of the transformed files, either "Source Image Color Space", meaning that the colorspace of the original image will be used, or sRGB, meaning that the colorspace will be transformed to sRGB.
5. Source file name prefix: Only files beginning with the value provided here will be transformed. For example, if you enter ABC, only files whose names begin with the string ABC will be processed. This field is optional.
6. Source file name suffix: Only files ending with the value provided here will be transformed. For example, you enter .jpg, only files whose names ends with the string .jpg will be processed. This field is optional.
7. Standard vs. Advanced configuration
   1. Standard mode automatically sets up the service to be run
   2. Advanced mode allows the user to configure the number and type of servers that will be used to run the job
      1. Number of Server Instances: The number of servers to use to perform the duplication task.
      2. Type of Server: The type (size) of server used as perform the task. The larger the server, the faster the processing will occur. Larger servers also cost more than smaller servers to run. For more information, see the Amazon EC2 documentation.

Service Output
All outputs of this service are placed in the system space, x-service-out.

CloudSync

Description:

The CloudSync service starts and runs the CloudSync application, which provides capabilities to allow the backup and restore of content from a Fedora repository into DuraCloud. For more information about CloudSync, please refer to its the CloudSync documentation.
