zoom function

The Planform app allows smooth zooming using either a touchpad or a mouse with a scroll wheel:

• Touchpad Users: Place two fingers on the touchpad, press and hold, then pinch inward to zoom out or stretch outward to zoom in.
• Mouse Users: Scroll the mouse wheel forward to zoom in or backward to zoom out.
• Zoom In tool: Simply draw a box around the region you want to enlarge, and the application will zoom into that area.

This helps you focus on specific sections of your PDF drawing with precision and ease.
