Use this information to configure a custom transform engine (T-Engine).

1. Define an HTTP URL and JMS queue name for the T-Engine.

   For example, you can configure custom T-Engines through environment variables:

   export TRANSFORMER_URL_<CUSTOM_ENGINE_NAME>="http://custom-engine-host:8090"
   export TRANSFORMER_QUEUE_<CUSTOM_ENGINE_NAME>="custom-engine-queue"
   

2. (Optional) Configure multi-step (pipeline) transformers:

3. Specify the mounting location of the pipeline definition file, custom-pipeline-file.json.

   For example:
   
   ```bash
   /local/path/to/custom-pipeline-file.json:/mounting/location/of/custom-pipeline-file.json
   ```
   

4. Specify the location through an environment variable.

   For example:
   
   ```bash
   export TRANSFORMER_ROUTES_ADDITIONAL_<name>="/mounting/location/of/custom-pipeline-file.json"
   ```
   

   Note

   The <name> suffix doesn't need to match any labels - it just differentiates multiple additional route files. However, the T-Engine name can be used as it may help to make debugging easier.

5. Create a JSON file that contains additional pipeline transformers.

   For example:

   {
     "transformers": [
       {
           "transformerName": "pdfToImageViaPng",
           "transformerPipeline" : [
             {"transformerName": "pdfrenderer",      "targetMediaType": "image/png"},
             {"transformerName": "imagemagick"}
           ],
           "supportedSourceAndTargetList": [
           ],
           "transformOptions": [
             "pdfRendererOptions",
             "imageMagickOptions"
           ]
       }
     ]
   }
