Dynamic Magnification (Scaling)

Dynamic Magnification (Scaling)

Dynamic scaling uses

<right mouse> + <left shift> &/or <left control>

(The distinction between the keyboard meta-keys is explained in Graphics modes during dynamic viewing above.)

The cursor symbol is green, and looks like:

Mouse motion to the right and up makes the image larger, left and down smaller. The initial position of the mouse is irrelevant.

Dynamic magnification using the mouse scroll-wheel

If your mouse is equipped with a scroll-wheel then it will also perform dynamic magnification in the graphics window in which the cursor is present.

• Magnification is centred at the current cursor position unless " CN Centre node" has been used to lock centring on a node.
  
  
• Scrolling towards you magnifies the image scale.
  
  
• Scrolling away from you reduces the image scale.

By default each scroll wheel "click" will change the magnification factor by +/- 5%, but this can be changed using the Options > Menu attributes panel, and altering the Zoom factor.
