Ocean Quigley Posted January 13, 2019 Share Posted January 13, 2019 Hi there, I'm using the Affine filter to make seamless, tiling textures - but I'm noticing that repeated application of the filter will slowly blur the image, until it's too blurry to use. I wish that it did a simple integer offset like Photoshops, and didn't degrade the image quality with each application. Thanks, Ocean Quote Link to comment Share on other sites More sharing options...
Staff Gabe Posted January 13, 2019 Staff Share Posted January 13, 2019 Hi @Ocean Quigley, I could not replicate this. Can you attach the project file so we can have a look? Thanks, Gabe. Quote Link to comment Share on other sites More sharing options...
John Rostron Posted January 13, 2019 Share Posted January 13, 2019 I have done several tilings recently. Each one has involved around half a dozen Affine transformations in both axes. I have seen no sign of degradation in any of these. John Quote Windows 10, Affinity Photo 1.10.5 Designer 1.10.5 and Publisher 1.10.5 (mainly Photo), now ex-Adobe CC CPU: AMD A6-3670.

Ocean Quigley Posted January 13, 2019 Author Share Posted January 13, 2019 Here's the easiest repro steps: 1. Make a new, fairly small pixel layer (say 256 square) 2. Paint a few very high-contrast (hard edged) black blotches on it 3. Apply affine say half a dozen times 4. Note that your edges are now blurry I'm guessing that it would be harder to notice the softening/blurring on a photographic texture, but it should be more obvious with a graphical one. Thanks!

So if you're offsetting a 1024 texture, use like 50%, or 25%, or any value that results in not splitting a pixel. Quote Link to comment Share on other sites More sharing options...

John Rostron Posted July 9, 2019 Share Posted July 9, 2019 I have to admit that the affine transformations that I performed were all with integral fractions of a 800px square.
