Zoom Control

Zoom control is commonly used when processing small barcodes or scanning from a long distance. There are two zoom control features:

• Auto-zoom: Lets the library determine whether to zoom in.
• Zoom factor: Lets you set the zoom factor directly. This is commonly used when focusing on small barcodes.
