Turn off anti aliasing when rastering an image in Affinity Designer

[Giezi]

I have a black and white pixelart image which I would like to rasterize, but instead of keeping the image crisp, the image gets all blurry:

Is there a way to turn anti-aliasing off when rasterizing and use nearest neighbor?

 

thanks

Welcome to the forums.
You can try changing the View Quality in Preferences/Performance, see attached image.
If that’s not enough then someone should be able to advise further.

[Giezi]

thanks for the answer.

Hmm no, I don't think this has something to do with performance, both images are inside Designer (and I tried to change the performance to Nearest Neighbours and the same thing happened). The one on the left is an "Image" object, and the one on the right "Pixel".

I found something which seems to do the trick, but I think it's a hack rather than an actual solution. Changing the "image dpi" to 1:

Are your pixel layers on pixel boundaries? It can make a big difference if the positions and sizes are not all integers.

[Giezi]

I'm sorry I don't understand what you mean by that.

My original image is a pixel art image, meaning each pixel you see is an actual pixel, does this help?

[GarryP]

If your pixel art is a pixel layer that has been placed into a document then the X, Y, Width and Height of that layer should all be integer values in pixels (not pt, cm, or others), otherwise you will get antialiasing. See attached video where the “X” is a 16×16 pixel square.

Ok, got it, thanks a lot for the video and for your help.

Yes, this seems to be the case. I made a video as well to better illustrate the issue:

You’re welcome. Good to know you’re sorted.

[Giezi]

Sorry, you misunderstood me. I meant to say that what you suggested is already the case, the width and height are integer values and the position as well.

The issue is still present, in the video, once I rasterize the layer, the image is not crisp anymore, but interpolated.

Hi Giezi,
Welcome to Affinity Forums
Go to Affinity Designer Preferences, User Interface section and increase the Pixels value in Decimal Places for Units Types area to 3 or more. Then check if the X,Y coordinates and width/height dimensions in the Transform panel are integer values (with the Image layer selected). Make sure they are integer values (remove the decimal part) before rasterising the layer.

Has there been any update on this? I'm trying to use Affinity Designer to experiment with Datamatrix codes at various resolutions, but anytime I print them they end up all blurry. Like OP, I also see this whenever I rasterize the image.

 

 

Right-click -> Rasterize...

 

 

Things also get blurry when exporting to Affinity Photo.

You can use nearest neighbor resampling for export (not for rasterizing layers inside an open document).

Then, you can adjust the antialiasing profile in blend ranges.

As you are using bitmap layers, a threshold adjustment may be used to heal any antialiasing.

In case of your gifs, the best way would be to upsample them separately (file by file) using pixel art resample.

In photo, the pixelate filter might remove unwanted antialiasing.

If you put a Curve in a group and then put that group in a group and set the coverage map for all three then it works properly... hope that helps.
