Image resizing

I am new to C++. I am using Intel's IPP for resizing an image in VS2015. I am trying to use ippiResizeLanczos_8u_C3R function to resize the image.

I do not know how to see/view the resized image or get the pixel values of the resized image(image after applying the above mentioned function), as I intend to use the resized image for further processing. The function perhaps returns only the "IppStatus". But I want to get the resized image or the data information(pixel values) of the resized image as return value.

Any help in this regard would be highly appreciated?

Hi Omair,

The parameter pDst is pointer to the resized image data. 

IppStatus ippiResizeLanczos_8u_C3R(const Ipp8u* pSrc, Ipp32s srcStep, Ipp8u* pDst, Ipp32s dstStep, IppiPoint dstOffset, IppiSize dstSize, IppiBorderType border, const Ipp8u* pBorderValue, const IppiResizeSpec_32f* pSpec, Ipp8u* pBuffer);

The documentation of the function can be found here: https://software.intel.com/en-us/node/504373

Best regards,
Valentin
