Calling this method brings the specified page into view but doesn’t move selection. Hence this method will work by default. That is, it works even if selection is not enabled.

In case, if you wish to move the selection to any page in document editor and bring it into view, you can use ‘goToPage()’ method of selection instance. Refer to the following code example.

Zooming

You can scale the contents in document editor ranging from 10% to 500% of the actual size. You can achieve this using mouse or touch interactions. You can also use ‘zoomFactor’ property of document editor instance. The value can be specified in a range from 0.1 to 5. Refer to the following code example.

Page Fit Type

Apart from specifying the zoom factor as value, the Document editor provides option to specify page fit options such as fit to full page or fit to page width. You can set this option using ‘fitPage’ method of document editor instance. Refer to the following code example.
