That was also at the back of my mind. But let us have a reliable better algorithm first. I often see ideas here on the list but often also without any response or results later :-(<br> <br> Thomas<br> <blockquote cite="mid:BLU157-W56D77F15D303ED824B49BFC4C00@phx.gbl" type="cite"> <div dir="ltr"> <div>William<br> <br> <div>> Date: Sat, 28 Jul 2012 09:33:38 +0200<br> > From: <a class="moz-txt-link-abbreviated" href="mailto:Thomas.Freitag@kabelmail.de">Thomas.Freitag@kabelmail.de</a><br> > To: <a class="moz-txt-link-abbreviated" href="mailto:abansal@linkedin.com">abansal@linkedin.com</a>; <a class="moz-txt-link-abbreviated" href="mailto:billhatesspam@yahoo.com">billhatesspam@yahoo.com</a><br> > CC: <a class="moz-txt-link-abbreviated" href="mailto:poppler@lists.freedesktop.org">poppler@lists.freedesktop.org</a><br> > Subject: [poppler] rotated/downsampled images<br> > <br> > Hi Arpit & Bill!<br> > <br> > In a quite short period You both offer to implement a better algorithm <br> > for rotated / scaled images than the Bresenham algorithm, one of You <br> > wants to implement the bilinear, the other the bicubic interpolation. <br> > Would be funny to see, which one is the better compromise between speed <br> > and quality.<br> > In splash always the scaling of an image is done first with <br> > Splash::scaleImage, and then the scaled image will be rotated in i.e. <br> > Splash::arbitraryTransformImage.
