anweid Posted January 25, 2021 Share Posted January 25, 2021 Affinity Designer 1.9.0.903 for Windows behaves as illustrated in the attached video (3 strange things): Draw a cat with your funny cat tool (which even draws a different one in Photo). Apply a contour and slowly increase the contour radius. At first, everything looks logical. At 0:09, one of the contour arcs snaps to the inside of the contour. At 0:14, it correctly snaps to the outside again. The inside snapping appears to be a bug. At 0:17, a small artefact appears at the right hind foot. At 0:22, a second one appears. At 0:37, a lot of of weird things start to happen until everything looks rather psychedelic at the end. This appears to be a limitation of the used algorithm and probably does not need to be corrected – nobody would want to equip anything with such a ridiculously wide contour, anyway. But take a look at the cat's neck: This is probably where the outline starts, and it seems to start and end with different slopes, creating a sharp groove at the inside of the contour, which doesn't look so nice. I would suggest that, in case an outline's start and end points do not have continuous slopes, to equip the contour not with a sharp groove, but either a straight line or a circular arc between the current contour's 'groove points'. Since this description might be completely incomprehensible: In the attached picture, the red area might be added to the contour, so that the groove vanishes, and everything looks smoother.

Staff Sean P Posted January 26, 2021 Staff Share Posted January 26, 2021 Hi anweid, The cat shape, unfortunately isn't a closed curve, so what you're seeing at the neck is the result of it being an open curve showing the start and end node caps. If you switch Contour Cap to Round, (or convert the cat to curves and then use 'Join Curves' it will also close the curve as you suggested, however this does need to be manually set. The issue with the hind legs/foot that you spotted is something that is already with development to be fixed, however I will get your comments passed on.

anweid Posted January 27, 2021 Author Share Posted January 27, 2021 Ah, I see. An 'unclosed cat'... The inside/outside arc problem still persists in version 1.9.0.911, but with a closed shape it depends on whether or not the contour is positive or negative. Even though you have already logged that bug, look at 0:06 and 0:12 of the video just in case, so you can see the two different behaviours.
