Mouse Wheel Zoom

Turning the mouse wheel will produce a zooming effect into or out from the drawing canvas depending on the direction of the mouse wheel turn. Turning the mouse wheel in the direction from the user will produce a zoom in and turning it towards the user will produce a zoom out. The zoom will vary depending on the position of the mouse pointer over the drawing canvas and the increment setting in Tools > Preferences > Miscellaneous.

In Tools > Preferences > Miscellaneous, the mouse wheel zoom can be turned off or on. The increment setting can also be changed between 1 and 20. This setting will effect the zoom level of the mouse wheel zoom. The higher the setting, the bigger the zoom effect will be.

The zooming center is the cursor position.
