Rotates this page by the specified angle.
public void Rotate(
int angle
)
Public Sub Rotate(
ByVal angle As Integer
)
public:
void Rotate(
Int32 angle
)
angle
Rotation angle in degrees. Positive values will rotate the page clockwise and negative values will rotate the page counter-clockwise. Must be in increment of 90 degrees.
This method changes the value of ViewPerspective based on the previous value and angle.
Refer to Document Page Transformation for more information.
This example will load a document, rotates and flips a couple of pages before exporting it to a new PDF.
