SetZoomLevel Method

Applies To: HTMLRenderer

Description

Sets the CEF ZoomLevel. The default (unzoomed) level is 0. Setting a positive value will increase the zoom, whereas setting a negative will decrease the zoom. The zoom scale is not linear; rather the effective scaling is approximately 1.2*level, so, setting the ZoomLevel to 1 will result in an approximate 20% size increase. ZoomLevel affects all instances of HTMLRenderer windows; it is not possible to have different ZoomLevels for individual windows.

The argument to SetZoomLevel is a single numeric value:

[1] ZoomLevel Numeric
