Supported values WTInvCol_D97_JPEG2K

Hi,
Why the function WTInvCol_D97_JPEG2K supports only the mod 32f_C1R while the function WTInvRow_D97_JPEG2K which seems symmetric supports the mods 16s_C1R, 32s_C1R and 32f_C1R ?
How I may work on columns with mods 16s_C1R, 32s_C1R ?

Thank you

Hi,

the function ippiWTInvColLift_D97_JPEG2K_16s_C1 is intended to use for 16s calculations.This ("Lift") group of functionsis advanced replacement for the previous column-oriented WT filtering functions.It's lower level, but suitable for effective implementation of scan-based wavelet transforms, which are faster because of effective usage of cash (especially on big images). Please, download JPEG 2000 codec sample (in IPP sample package) to seefull implementation of WT.

Regards,
Mikhail
