how to scale gray scale image using accelerate framework (vImage)
===

Hi i need to scale a gray scale image fast, so i tried vImage and the app is crashing, please help. In the below code srcimg.data/dstimg.data is a point to unsigned char image data(single channel only gray data).
<pre>
                    vImage_Buffer src;
                    src.data=srcimg.data;
                    src.height=srcimg.cols;
                    src.width=srcimg.rows;
                    src.rowBytes=srcimg.cols;
                    
                    vImage_Buffer dest;
                    dest.data=dstimg.data;
                    dest.height=dstimg.cols;
                    dest.width=dstimg.rows;
                    dest.rowBytes=dstimg.cols;
                    vImageScale_Planar8(&src, &dest, NULL, kvImageNoFlags);
