Detailed Description
The IplImage is taken from the Intel Image Processing Library, in which the format is native.
OpenCV only supports a subset of possible IplImage formats, as outlined in the parameter list above.
In addition to the above restrictions, OpenCV handles ROIs differently. OpenCV functions require that the image size or ROI size of all source and destination images match exactly. On the other hand, the Intel Image Processing Library processes the area of intersection between the source and destination images (or ROIs), allowing them to vary independently.

| int align |
Alignment of image rows (4 or 8).
OpenCV ignores it and uses widthStep instead.
