ScaleTransformationBuilder

java.lang.Object
- lumis.portal.file.transformation.ScaleTransformationBuilder

All Implemented Interfaces:

ITransformationBuilder
```
public class ScaleTransformationBuilder
extends Object
implements ITransformationBuilder
```
Scale transformation builder is based on content type and service instance to decide the right ITransformation.

For convention the args parameter must be created using keys in upper case and their values should be a string. Only reductions are allowed, always keeping the proportionality.

Since:

6.1.0
