+description: |-
+  The Dewarp Engine provides high-performance dewarp processing for the
+  correction of the distortion that is introduced in images produced by fisheye
+  and wide angle lenses. It is implemented with a line/tile-cache based
+  architecture. With configurable address mapping look up tables and per tile
+  processing, it successfully generates a corrected output image.
+  The engine can be used to perform scaling, cropping and pixel format
+  conversion.
