Rotate Pages

This example shows how to rotate pages:

java

//  Rotate the first page 90 degrees clockwise.
document.pageAtIndex(0).setRotation(90);

kotlin

//  Rotate the first page 90 degrees clockwise.
document.pageAtIndex(0).rotation = 90

When the document is bound and displayed through CPDFReaderView, after modifying the document pages, you need to call the following method to refresh the view so that the changes take effect immediately:

cpdfReaderView.reloadPages();
