Af Photo displaying issue

[DudeDom]

Hello there,

I guess my issue is very simple to solve, but I can't figure it out. In my performance settings everything is set to highest. My question is now, why do I still see pixelated things which is not visible in the output.
I mean, can't I just see how its actually displayed?

This is in Affinity Photo, as you can see, everything looks pixelated:



This is a png from this file, as you can see, everything looks clean:



Performance Settings in Af Photo:





Why does it look so pixelated?

Attaching the .afphoto file might get you an explanation or solution more quickly.

Unfortunately I haven't saved the file. I have noticed that the problem occurs when zooming to image size (by default with CTRL + 0). My monitor has a resolution of 2560x1440, the file is 1920x1080 and therefore the display may be at an inappropriate percentage. Nevertheless it should not be pixelated, even with strange percentages. I actually expect a normal display of my file, no matter what percentage.

Your screenshot reveals that the AP zoomed-in view was using Nearest Neighbour resampling, not the Bilinear that is specified in the app preferences.

In AP on my iMac which has a Retina display, the view uses Nearest Neighbour resampling when zoom is greater than or equal to 200%, regardless of Bilinear being set in the app preferences. I guess Nearest Neighbour is happening for zoom greater than 100% on your display because it is not classed as a Retina display.

Well, this user has this issue as well and he's using a retina display...

I guess you are referring to the statement, "In Affinity Photo on 200% [...] the pic looks pixeled. When I open the same photo with safari, it has the same size but does look smooth."

As I wrote earlier, a zoom of 200% or greater in AP (on a Mac, at least) when the display is Retina employs nearest neighbour resampling, regardless of bilinear being specified in the app preferences. That resulted in the "pixeled" appearance of each image pixel being displayed by a square block of four identical display pixels. Safari used bilinear resampling to double the image size, hence the "smooth" (actually fuzzy) appearance.

I guess this discussion doesn't bring us too far. Retina Display or not, I never (!) had this issue with Photoshop, so my monitor is good enough to display images smoothly in which size/scale ever. This is clearly a software issue and not a hardware issue. The way Af Photo renders the image is just bad. Hope there are some more tips than "using a retina display will fix your issue".

You can even see the pixelelated screenshot, can't you? This is the proof, that its a rendering issue with the software and has nothing to do with the display/monitor I'm using!

I'm only telling you what is happening. I'm just a user. There's nothing I can do to change the software.

I certainly did not say that your display is at fault.

I certainly did not say that using a Retina display will fix anything.

I certainly did not advise you to use a Retina display.

I now regret trying to provide you with information.
