On further investigation, it seems as if the problem is not in the rendering of the text into the offscreen bitmap context, but the later scaling down of that image in a CALayer.
On the Mac, when I set the layer's minificationFilter property to trilinear, that produces nice results, but on iOS, this filter *seems* not to be implemented, which may make sense. Is there a supported way to get smooth downsampling on iOS? If not I may be able to create the image such that no downsampling is needed, but that will be a lot more complicated than letting the layer handle it, so if possible, I want to avoid that. --Graham On 10/06/2011, at 10:30 AM, Graham Cox wrote: > > On 10/06/2011, at 3:24 AM, David Duncan wrote: > >> I imagine what you are expecting is LCD antialiasing, which I am fairly >> certain is not done on iOS.
