Zoom() Function

Zoom(factor)

factor - Specifies the zoom factor.

• The current screen size is multiplied by the zoom factor parameter. For example, factor of 2 will double the size. 0.5 will half the size.
  
• You can increment or decrement the current zoom by prepending the size value with a plus(+) or minus(-) sign. This is ideal for creating a zoom in and zoom out buttons (see example below).
  

<xml id="toolbar">
<control type="toolbar">
<button caption="Zoom In" action="Zoom(+0.2"></button>
<button caption="Zoom Out" action="Zoom(+0.2)"></button>
</control>
</xml>



The above code creates a simple toolbar with a zoom in and a zoom out buttons. Each click of the button increases or decreses the screen magnification by 20%.

Requires ToolbarBrowser version 2.2.2 or later.
