## Mirror the image with roiSize has a field (height) = 1

Hi,
I am using "ippiMirror_32s_C1R" to mirror the image. The roiSize is {252,1}. As per the new IPP V7.1 , it gives me an error "ippStsSizeErr". it was giving no issues with my earlier version ipp5.
Any other API/way to do the mirroring when one of the element in ippiSize is 1. Thanks for the help

You couldconsider transpose functions from theMatrix Processing domain of IPP.

Your image is very small and I think STL's 'reverse' functioncould be used instead:

[cpp]#include #include ... // Initialize a vector with an array of integers int arr[10] = { 2, 1, 4, 3, 6, 5, 8, 7, 10, 9 }; vector< int, allocator< int > > v( arr+0, arr+10 ); // Print out elements in original (sorted) order cout << "Elements before reverse: " << endl << " "; copy( v.begin(), v.end(), ostream_iterator< int, char, char_traits< char > >(cout," ") ); cout << endl << endl; // Reverse the ordering reverse( v.begin(), v.end() ); // Print out the reversed elements cout << "Elements after reverse: " << endl << " "; copy( v.begin(), v.end(), ostream_iterator< int, char, char_traits< char > >(cout," ") ); cout << endl << endl; ... [/cpp]
Here is output:

Elements before reverse:
2 1 4 3 6 5 8 7 10 9

Elements after reverse:
9 10 7 8 5 6 3 4 1 2
