Resizing pixel art by nearest neighbor algorithm

[kamone]

Hi, I’m using Affinity Photo on iPad and having fun. Yesterdays update was great.

I’m trying to resize my pixel art drawn on a small 48x48 canvas to x3 size.

I used the resize menu and selected “pixel”. I want to make sharp accurate images, but the result has anti-ailiasing and gets soft. I tried both xBR and hqx modes.

 

Is there a way to resize like nearest-neighbor option in photoshop?

If not, I wish it comes on an update.

Hi kamone, you can use nearest neighbour resampling which should give you the sharp-edged result you're after (XBR and HQX, whilst useful, won't give you the result you want). Nearest Neighbour resampling is under normal document resizing, so on the resize dialog all you need to do is set Resize to Document - look for the Sampler option and set that to Nearest for nearest neighbour resampling. Hope that helps!

 

Also worth noting is that XBR and HQX both only work as intended with proper 1:1 pixel art created from scratch - that is, every pixel is unique and represents itself. Images that have been downscaled or are "emulated" pixel art end up looking odd and "painterly" when upscaled with these filters.

Sorry for necroing this post, but: is that really all Affinity can? Either resize the whole document with Nearest Neighbor or be stuck with it? Or is it actually possible to set a scaling filter on the object selection tool? I have a document with multiple pixelart images in it and I want to resize all of them with nearest neighbor except one (because it's text).

You're thinking of Publisher now, right?

Unfortunately, that's all Affinity is capable of. I was recently looking for previous requests about setting the resample algorithm per image in Publisher, but I didn’t really have the energy to submit a new request — it seems to be futile.

I actually didn't see this is an post related to the iPad version but I'm, in general, talking about Affinity software. Neither Photo nor Designer can resize a single layer with a specific scaling in place.

But I agree it seems to be futile. I still have the same daily issues I had back in 2018 when I bought the software.

There was temporary the option to choose resample method and repeat mode in fill tool for vector layers with bitmap fill, but this got removed again (forgot why) when memory serves me well. And this lacked support to define integer scaling factors instead of mouse and guessing (did not show bitmap org size).
