Pixel upscaling improvement requests


Recommended Posts

Hi,

I love it that Affinity Photo includes pixel art upscaling algorithms, and I've got a kind request for some improvements. Many thanks in advance.

Currently, the best pixel art upscaling algorithm in Affinity Photo is xBR, but there is an improved version of xBR called xBRZ, which is noticeably better, and makes the regular xBR obsolete / dated.

Also, xBRZ can upscale up to 6 times, while xBR stops at 4.

I've attached an enlarged comparison of my pixel art upscaled with both xBR and xBRZ (4 iterations).

It certainly looks like xBRZ preserves shapes much better. Can we see the original before scaling?

Thanks for your reply. The original is at the top, upscaled with the straightforward Nearest Neighbour method to match the size of the other images.
