I just test this case (17x17) and function returns a valid pointer. Did you noticed that the third parameter should be pointer to integer variable where function will store step between adjacent lines of allocated image?</DIV> <DIV></DIV> <DIV>Regards,</DIV> <DIV> Vladimir</DIV> Tue, 12 Oct 2004 22:41:05 GMT https://community.intel.com/t5/Intel-Integrated-Performance/Problems-with-ippiMalloc-funciton/m-p/935203#M17109 Vladimir_Dudnik 2004-10-12T22:41:05Z
