toltec Posted June 16, 2017 Share Posted June 16, 2017 If I load a file as an Image and resize it up in it's layer. What resizing method would it use for that image layer if I exported the whole document later, as say a TIFF or JPEG, with the resized image included. If I resize the whole document, I can choose Bilinear, Lanczos 3 etc. But what happens with resizing the embedded image layer. Ta Quote Windows PCs. Photo and Designer, latest non-beta versions.

JET_Affinity Posted June 17, 2017 Share Posted June 17, 2017 If you rasterize the whole document, raster images already contained in it will be re-rasterized according to the same settings. JET Quote Link to comment Share on other sites More sharing options...
toltec Posted June 17, 2017 Author Share Posted June 17, 2017 Yes, but what if I don't rasterize the whole document? What happens if the whole document is already the right size. except for the one small image in the middle that will need to be resampled to match the rest of the document when I output it as a TIFF or whatever? How do I choose the resampling method for that image? Quote Windows PCs. Photo and Designer, latest non-beta versions. Link to comment Share on other sites More sharing options...
anon1 Posted June 17, 2017 Share Posted June 17, 2017 If you export, the rewamplijg method can be adjusted in the export settings If you rasterise in place though AP uses something bad like nearest neighbour You can check this by 1. Open picture in document one 2. create second document with e.g. 1/4 of the pixels 3. copy the image and resize using the move tool to fit, export using langszos 4.rasterize the image and export again using the same settings (although the resamplijg method at this point will not make a difference) Affinity does not think this is an issue though https://forum.affinity.serif.com/index.php?/topic/21222-rasterizing-algorithm/?p=99188 Cheer Quote Link to comment Share on other sites More sharing options...
Fixx Posted June 17, 2017 Share Posted June 17, 2017 It is either an issue or a problem. Internal resample should be something better that nearest neighbour. reza55n, DavidMac and Krustysimplex 3 Quote Link to comment Share on other sites More sharing options...
toltec Posted June 17, 2017 Author Share Posted June 17, 2017 Hmm, that's not very good at all. :( I will have to remember to get all the images at exactly the right size before I put them into a page. Or, maybe resize the whole document afterwards and force it to use Lanczos 3 or something. To be honest I normally work at higher resolutions and downsize. Maybe I'm just being picky :unsure: After all, expecting my professional quality photo editing program to behave in a professional manner every time is a bit much .

anon1 Posted June 17, 2017 Share Posted June 17, 2017 Well As long as you just scale images down and do not rasterise, you are fine and you can scale up and down again and again as you like Just, do not rasterise Cheers Quote Link to comment Share on other sites More sharing options...
toltec Posted June 17, 2017 Author Share Posted June 17, 2017 Well, maybe I shouldn't export either. The same issue will crop up. While I'm at it, better avoid printing too. :lol: :lol: :lol: That's the problem. Sooner or later Affinity will decide to rasterize it for me and seems to use, nearest neighbour, which is the worst of all worlds. Quote Windows PCs. Photo and Designer, latest non-beta versions.

toltec Posted June 17, 2017 Author Share Posted June 17, 2017 Good, point. I shall, as you said, "never rasterize" inside an Affinity document. If I have to edit an image (which I often do) I shall make sure it is sized up first, before I place it and rasterize it. I would like to see a better option available though. Nearest neighbour is not very good, even at downsizing. Quote Windows PCs. Photo and Designer, latest non-beta versions. Link to comment Share on other sites More sharing options...
Alfred Posted June 17, 2017 Share Posted June 17, 2017 Nearest neighbour is not very good, even at downsizing. Bicubic is good for downsizing and Lanczos3 Window is good for upsizing. Nearest Neighbour seems a strange choice for a default method, never mind a fixed one, although it's great if you actually want the result to be pixellated!! :lol: BTW, every time I read the topic title I find myself thinking, "Hmm. How do you rasterize thoughts??" :P Quote Alfred Affinity Designer/Photo/Publisher 2 for Windows • Windows 10 Home/Pro Affinity Designer/Photo/Publisher 2 for iPad • iPadOS 17.4.1 (iPad 7th gen) Link to comment Share on other sites More sharing options...
R C-R Posted June 17, 2017 Share Posted June 17, 2017 Do we know for sure that rasterizing an image layer uses Nearest Neighbor? I know I have read some of the staff saying they think it does, but have we actually heard that from a developer?

toltec Posted June 17, 2017 Author Share Posted June 17, 2017 Like many things Affinity, "Clarity" is a filter that only works on pixel layers, not image layers :lol: Actually, it does, but it seems like it doesn't.

It is worrying that professional software I paid for does nearest neighbor resampling for something very integral to the image manipulation process.
