topic ROI size limitation in Intel® Integrated Performance Primitives

ROI size limitation

ezeng3 — Wed, 05 Dec 2018 06:21:58 GMT

Hi, All

I am trying to copy an image with image width 44672 and image height 51480. I am trying to use ippiCopy_8u with this size, but it does not copy successfully, although the return code is ippStsNoErr.

On the other hand, if I use ippiCopy_8u block by block, it can copy successfully.

The testing is performed in 8.0 update 1. I am not sure if the latest version has corrected this issue, neither it specifies the maximum size of the ROI for the online document

https://software.intel.com/en-us/ipp-dev-reference-regions-of-interest-in-intel-ipp

So i want to clarify with the experts that if the integer limitation (2^31-1) is the hard limitation of the ROI for all the ippi functions?

Best Regards

Edwin Zeng

Hi Edwin,

the issue has been addressed since IPP 2017 ( https://software.intel.com/en-us/articles/intel-ipp-platform-aware-apis-to-support-64-bit-parameters-for-image-dimensions).

Please try the latest version.

Thank you
