All Implemented Interfaces:
```
public final class Transformation.Page

                    
```
Extracts a specific page or frame from multi-page or layered files (PDF, PSD, AI). For example, specify by number (e.g., 2), a range (e.g., 3-4 for the 2nd and 3rd layers), or by name (e.g., name-layer-4 for a PSD layer). See Thumbnail extraction.
