When we rotate image by 90 degree usingippiRotate_8u_C4R() , for MxN resolutions the output is MxN image with 2 black strips at the sides of the image. Is it possible to get rid of these black strips? Is it possible to change the size of the image to NXM ? or Is it possible to change the size of the image to MxM ?
We are trying to remove these black strips by the calling the functionippiRotate_8u_C4R() and thenippiResizeShift_8u_C4R(), this does the trick but image get stretched and there is peformance hit in our application because of calling two functions. Is there any other way to acieve this through a single call ?
Need help on Image rotation.
