SMrak Posted October 31, 2019 Share Posted October 31, 2019 (edited) It looks that 'resize canvas' option have a bug - which will blur the image. I have attached three images here, first two are zoomed to 200% to better see the bug, and third image (original/smaller at the bottom) is here if you want to try it for yourself. How to reproduce the bug: 1. Open/load image to AP (the smaller one at the bottom of this post which is 433x178px) 2. set "resize canvas" to 450x185px with anchor set to "center", "left" or "right" 3. see the results (the image will be blurred) I'm using the latest AP version 1.7.3 Edited October 31, 2019 by SMrak Alej 1 Quote Link to comment Share on other sites More sharing options...
SMrak Posted October 31, 2019 Author Share Posted October 31, 2019 Update: If hardware acceleration is disabled (Metal), everything is working fine. Alej 1 Quote Link to comment Share on other sites More sharing options...
Old Bruce Posted October 31, 2019 Share Posted October 31, 2019 Has more to do with arithmetic than Metal hardware acceleration. You are moving the picture up/down by a half pixel instead of a whole pixel because of the number of pixels' increase. 17 hi by 7 wide.

SMrak Posted November 1, 2019 Author Share Posted November 1, 2019 Ok, i understand your logic ... but why i'm getting different results with Hardware Acceleration enabled / disabled ? Quote Link to comment Share on other sites More sharing options...
Staff Gabe Posted November 8, 2019 Staff Share Posted November 8, 2019 Hi @SMrak, Sorry for the delayed reply. I don't see any difference between metal on/off. Regardless of that, when you anchor to centre, it will be placed on half-pixel values as @Old Bruce mentioned. This is not a bug.
