UIImage ScaleToFit disable antialias?

Question

antialiasing in UIImage scale to fit

is there any way to disable antialiasing when scaling images in uiimage? thanks

For google's sake, this is also called bitmap smoothing, anti aliasing, sampling, upsampling, downsampling, resampling, and making pixels sharp when scaling or a scale transform is applied. =) — Jeff Ward, Feb 14 '12 at 22:58

Add the QuartzCore framework to your project, then set the image view’s layer’s magnificationFilter property to kCAFilterNearest.

For MonoTouch users this constant is available under: CALayer.FilterNearest – Jacob Foshee Jun 11 '12 at 15:20

I was working with SpriteKit in Xcode 11 (Swift 5) and also got this problem. To solve it (i.e. disable anti-aliasing) i did the following:

texture?.filteringMode = SKTextureFilteringMode.nearest
