+ImageManip Rotate
+=================
+
+This example showcases how to rotate color and mono frames with the help of :ref:`ImageManip` node.
+In the example, we are rotating by 90°. 
+
+.. note::
+    Due to HW warp constraint, input image (to be rotated) has to have **width value of multiples of 16.**
+
+Demos

+ImageManip Tiling
+=================
+
+Frame tiling could be useful for eg. feeding large frame into a :ref:`NeuralNetwork` whose input size isn't as large. In such case,
+you can tile the large frame into multiple smaller ones and feed smaller frames to the :ref:`NeuralNetwork`.
+
+In this example we use 2 :ref:`ImageManip` for splitting the original :code:`1000x500` preview frame into two :code:`500x500` frames.
