In some painting system, e.g. the Qt port of WebKit, optimization can be made if e.g. the rectangle is pixel-aligned. Solution: introduce GraphicsContext::fillRect(IntRect). Default implementation will just wrap the FloatRect version. 93392 1 23945 ariya.hidayat 2008-09-30 11:10:51 -0700 Created attachment 23945 introduce GraphicsContext::fillRect(IntRect) 93395 2 simon.fraser 2008-09-30 11:24:43 -0700 Why not just test if (rect == FloatRect(enclosingIntRect(rect)) inside your fillRect implementation? 93399 3 23947 ariya.hidayat 2008-09-30 11:52:22 -0700 Created attachment 23947 Detect pixel-aligned rect Another variant of the patch, no need for GraphicsContext::fillRect(IntRect). Just specialize handling of IntRect inside GraphicsContext::fillRect(FloatRect). 93435 4 23947 eric 2008-09-30 14:47:49 -0700 Comment on attachment 23947 Detect pixel-aligned rect Please review the webkit coding style: http://webkit.org/coding/coding-style.htm and correct the errors in this patch. Otherwise this looks fine. I'd rather see "enclosing" called "enclosingRect" since it's a rect. :) I'm surprised Qt doesn't do this internally already. CoreGraphics on mac os x certainly does. IMO this seems like a hack around deficiencies in the Qt API. r- for the coding style violations. 94352 5 ariya.hidayat 2008-10-07 04:16:32 -0700 I decide to fix Qt instead. So I close this bug. 23945 2008-09-30 11:10:51 -0700 2008-09-30 11:52:22 -0700 introduce GraphicsContext::fillRect(IntRect) webkit-graphicscontext-fill-intrect.patch text/plain 4567 ariya.hidayat
