Designer1 Posted March 3, 2021 Share Posted March 3, 2021 When exporting vector graphics to PNG and JPG from Affinity Designer, better anti-aliasing of the contours would be appropriate. The contours do not look as smooth as when exported from Adobe Illustrator. Zoom 100%. Quote Link to comment Share on other sites More sharing options...

Understood, which is why I commented in the linked thread about the antialiasing being ‘somewhat lacking’ (i.e. not as good as it could be).

Designer1 Posted March 3, 2021 Author Share Posted March 3, 2021 @ Patrick Connor There has long been a problem with anti-aliasing when exporting vector graphics to PNG. The contours are not as smooth as they should be. Can you please forward this problem to your development department? Quote Link to comment Share on other sites More sharing options...

Designer1 Posted March 4, 2021 Author Share Posted March 4, 2021 It's not about display which one you have. The smoothing of the graphics could be much better. Here is an example from CorelDraw. The smoothing is better. Quote Link to comment Share on other sites More sharing options...
John Rostron Posted March 4, 2021 Share Posted March 4, 2021 @Designer1, these two images look the same to me apart from the colour.

walt.farrell Posted March 4, 2021 Share Posted March 4, 2021 It would help if you showed us examples that were the same size. However, I copied a screenshot of both from the forum, and resized the one from Coreldraw to be the same size as the other, then recolored it red, reduced its opacity, and overlayed the two images. They are virtually identical, though they do show small differences (look for the reddish or blue-gray fringes around the letters). I would not call either "smoother", just different.

John Rostron Posted March 4, 2021 Share Posted March 4, 2021 I downloaded the two images, the original from Afffinity and the final one from Corel Draw. I loaded them into a stack with alignment (they were both the same size) and ungrouped the stack. By changing the visibility of the top layer I could quickly compare the images. At 100% I could detect no difference. At 300% I could see that they were different, but I could not say that one was better than the other.

Designer1 Posted March 5, 2021 Author Share Posted March 5, 2021 Here png from Affinity Designer and CorelDraw. Both images are the same color and size. The inner rounding at b in Affinity is not as smooth as in Corel. The contour in Affinity is somewhat coarser. I would say that the anti-alias is pretty perfect with Corel and unfortunately not with Affinity Designer. With Affinity Designer, anti-aliasing could be finer. If you enlarge the images to 300%, you can see that Corel's contour is finer and therefore smoother. Possibly it is because Corel PNG has 24 bit?

John Rostron Posted March 5, 2021 Share Posted March 5, 2021 I did the same thing with these two as I did to your earlier images, with the same result. At 100% there was no detectable difference between the two. At 300% I could just discern a difference, but not to say one was better than the other.

Below are three screenshots obtained after zooming in on my iPad to make them fill its 9.7″ screen. Can you tell me which one appears twice, and which app it’s from?

The first abc is from Affinity and the second from Corel. The point is for the Affinity Designer development team to look at my examples. With Affinity, the smoothing can be better.

Looking at them again now, I can see that the lower left-hand corner of the ‘a’ is a little bit ragged, with a very slight hint of the same problem on the bowl of the ‘b’, but I don’t think it would have been easily perceived if we only had the ‘b’ and the ‘c’ to inspect.
