I am revisiting an old project written with ippi 4.
I want to reduce large images using SuperSample. I also want to keep the scaling in both directions identical. I think I want to use.
In the docs there is an interpolation mode called,
but this is missing from the header files. Is this an oversight? what is the correct value of IPPI_INTER_CUBIC2P_SUPER. Is this mode to be supported in ResizeSqrPixel into the future?
I cannot use SuperSampling as a substitute as it is roi based instead of scale value based. The effect of pixel rounding in this way would cause artefacts given the way I am using the images.
By mistake we have added this mode (IPPI_INTER_CUBIC2P_SUPER - supersampling interpolation) into the Manual, corrected in the upcoming release of IPP. It means we have removed it from the ippiman.pdf.
Does this mean that you have removed the capacity to resize images using Super Sampling with identical scaling in the x and y directions? This is possible with the depricated Resize but not with the new SuperSample function.
To remove this feature would be a reduction in the capabilities of the library. If you are doing this please rethink as my use of ippi depends on it.
No, there is Super Sampling method for the functions ippiResize, ippiResizeSqrPixel and ippiSuperSampling
IPPI_INTER_CUBIC2P_SUPER was an erratum
