If you’re using a transparent sheet, you don’t know in advance what the pixels below it will be. They may change. Remember that you have a single alpha channel for all three colors: if you make it transparent, you won’t see any subpixel effect, but if you make it opaque, all three subelements are going … Read more
From the Release Notes: https://developer.apple.com/library/content/releasenotes/DeveloperTools/RN-Xcode/Chapters/Introduction.html#//apple_ref/doc/uid/TP40001051-CH1-SW680 Text and font rendering on OS X v10.8 is optimized for Retina display. On a non–Retina display running OS X v.10.8, some font configurations can appear blurry in Xcode. 11486875 Switch back to non–Retina display optimized text and font appearance in Xcode by enterin this command in Terminal: defaults write … Read more
You need to set the Image’s render options. Try setting the style of the Image to: <Window.Resources> <Style TargetType=”Image”> <Setter Property=”Height” Value=”64″ /> <Setter Property=”Width” Value=”64″ /> <Setter Property=”RenderOptions.BitmapScalingMode” Value=”HighQuality” /> </Style> </Window.Resources> To use the image, simply call as before: <Image Source=”/Images/MyImage.png” /> Or, to use the RenderOptions on a single image: <Image RenderOptions.BitmapScalingMode=”HighQuality” … Read more
As it turns out, Java2D (which I’m assuming is what you’re using) is already pretty good at this! There’s a decent tutorial here: http://www.javaworld.com/javaworld/jw-08-1998/jw-08-media.html The important line is: graphics.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
By default, JavaFX 8 uses modena.css to set the LCD anti aliasing, which doesn’t seem to smooth out fonts in some cases. When the font size is larger than 80 px, the AA technique switches to grey scale AA (for performance reasons). So, to achieve smooth edges at any size, grey scale AA should be … Read more
One can achieve the effect of anti aliasing very cheaply using vertices with opacity 0. Here’s an image example to explain: Comparison with AA: You can read a paper about this here: http://research.microsoft.com/en-us/um/people/hoppe/overdraw.pdf You could do something along this way: // Colors is a pointer to unsigned bytes (4 per color). // Should alternate in … Read more
There’s no question at all – you still need to do antialiasing mathematics, because of the complexity of curves, second order curves, intersecting curves, and different types of joins. (Note too that, very simply, since this question appeared two years ago. Retina displays are now ubiquitous and – indeed – antialiasing is, in fact, done … Read more
It’s now possible to get sub-pixel font rendering by creating an opaque canvas context. In Safari and Chrome you can get this using this snippet: var ctx = canvas.getContext(“2d”, {alpha: false}) I found this from this blog post.
