https://community.intel.com/t5/Intel-Integrated-Performance/Image-resizing-question/m-p/982594#M21473 Hi,<BR /><BR />I'm resizing large images (&gt;10000x10000, rgb or cmyk) using the ippiResize functions.<BR /><BR />Am I correct in thinking that the functions require a whole image to be loaded into memory? (not neseccarily a problem as memory is cheap)<BR /><BR />Also, are there some sizes &amp; scaling which work best? eg I know there are optimal ways of scaling to 50%, 33%, does the ippiResize also benefit at these scalings?<BR /><BR />I've been musing about loading either a few scanlines at a time, or breaking the images into tiles - would a 10x10 set of 1024x1024 image tiles scale faster?<BR /><BR />thanks,<BR />Alistair Thu, 28 Jul 2005 15:32:09 GMT abraidwood 2005-07-28T15:32:09Z https://community.intel.com/t5/Intel-Integrated-Performance/Image-resizing-question/m-p/982594#M21473 Hi,<BR /><BR />I'm resizing large images (&gt;10000x10000, rgb or cmyk) using the ippiResize functions.<BR /><BR />Am I correct in thinking that the functions require a whole image to be loaded into memory?

Please, download "w_ipp-sample-image_b_5.0.006.zip" file, you can find in this archive image-tiling sample</DIV> <DIV></DIV> <DIV>Regards,</DIV> <DIV> Vladimir</DIV> Fri, 12 Aug 2005 23:31:59 GMT https://community.intel.com/t5/Intel-Integrated-Performance/Image-resizing-question/m-p/982595#M21474 Vladimir_Dudnik 2005-08-12T23:31:59Z
