StuartPearson Posted January 17, 2020 Posted January 17, 2020 When using the patch tool, when the selection is moved there appears to be a blend applied to the displayed image, it is even more noticeable if you use the tool at the edge of an image. I would have expected the patched area to have exactly the same content as the copied area Stuart FullSizeRender.mov Quote
Staff Chris B Posted January 20, 2020 Staff Posted January 20, 2020 Hey Stuart, I logged this last year with the developers however it was closed as by design due to the image I was testing it on. The image in your video is also similar as in there are so many tones, shades and colours that the algorithm is indeed trying to blend them together. If for example, you attempted removing a cluster of blemishes from a cheek, you should see no such issue. Quote How to format a bug report | Learning Resources | List of V2 FAQs | YouTube Tutorials

I was under the impression that the patch tool with blend set at normal should just be effectively copying the pixels from the source so should be an exact copy. I don’t see where an algorithm would be involved. Quote
Staff Chris B Posted January 22, 2020 Staff Posted January 22, 2020 I imagine it attempts to blend the surrounding pixels of the selected area with the destination pixels. If they differ greatly, the algorithm gets confused and starts bringing in random colours. The tool works fine when using it to remove a blemish from a skin tone but in your video, you have blues, whites, browns, greys and yellows within the selected area so I think you're asking too much from the tool and this isn't typically what it would be used for. The tools primary use is for repairing damaged areas of an image. Quote How to format a bug report | Learning Resources | List of V2 FAQs | YouTube Tutorials
StuartPearson Posted January 22, 2020 Author Posted January 22, 2020 Thanks for the info, I was misunderstanding the patch function, I have just read the inbuilt help on it and it confirms the blending. Explains other occasions why it hasn’t behaved how I expected it to Chris B 1 Quote
Staff Chris B Posted January 22, 2020 Staff Posted January 22, 2020 No worries! I think the help often gets overlooked or is forgotten about, which is a shame because it is really handy and I refer to it all the time Quote How to format a bug report | Learning Resources | List of V2 FAQs | YouTube Tutorials
