I believe vid's scaling is called ...heh I can't even remember it... without any kind of resampling I mean
![]() Some hardcore for increasing image: link but of course its the best. For lowering image dimensions there's vids representation with SSE help ![]() One more link that you probably found yourself already: http://www.compuphase.com/graphic/scale2.htm Btw, does anyone know how to get to the C-drive of http://www.sandpile.org/docs/intel/isa-ext.htm ? I would love to see those PDF-s. Especially scoll down to AVX! |

Oops, nope, it was too small ![]() Its a rather tempting linking they got there: file:///c:/home/manuals/intel/isa/avx/lanczos.pdf Alphonso wrote: Madis731: Is this something like what your looking for IIR , Lanczos ? Hmm, that was my half-goal. Actually seems that they've gathered interesting documents in one place, but when the Intel PDFs are public, how can or WHY? would sandpile hide them from the masses? ... I hope the Alphonso's posted links help Dex4u develop image scaling ![]() |
