Image / NSImage – getting weird 'sub-pixel' like artifacts

Forums > SwiftUI

Hello - been trying to figure this one out the last day or so.

I have an image that I am displaying and even if the scale / frame size exactly matches the original I am getting a weird (almost sub-pixel like display - when at 1X or maginified to any above 2X, 5X, 16X). Interpolation is .none

I took the same image / JPEG and exported to both JPEG and PNG from Photoshop and had no issues with those versions.

I also tested some strict checkerboards of B&W and in color and had no similar issues.

Do I have a cursed JPEG of some sort?

Zoom in on these in Preview or Photoshop to see... Chrome blurs/interpolates on zoom in.

one with weird splits (original JPG - screenshot is PNG) Weird split of some singular pixels in left and right halfs

exported JPG from Photoshop (normal / solid pixels singletons - screenshot is PNG) Expected singular pixel display

general UI at the moment (is a remake of an old GUI I did for JPEGTRAN back in like 2005... trying to learn SwiftUI) Cursed UI
