Staff MEB Posted March 22, 2018 Staff Share Posted March 22, 2018 Hi bowen192, You can only change the alignment of closed shapes. If that's an open path you can't do it. Can you please check if that's the case? bowen192 1 Quote A Guide to Learning Affinity Software | Affinity Quick Reference Link to comment Share on other sites More sharing options...

gdenby Posted March 22, 2018 Share Posted March 22, 2018 But how would the stroke be exported in an .svg file? AFAIK, SVG assumes there is a center point for a fill that is determined by the vector perimeter, and that can only be determined if the shape is closed. The 1st and last nodes of the shape can be reversed, but that doesn't do anything to define inside and outside. I suppose there might be a way to create a routine that finds the the 1st and last input for line A-B = B-A, and does an XY offset for a stroke. But again, how to render that into the SVG standard, which defines inside and outside by projecting a ray from a(n) implied center to infinity.

Your picture shows the first arrow on the right side of the segment but the second arrow on the left: it's completely arbitrary. And what about an 'S' (or an inverted 'S') where one half of the curve is concave on the right but the other half is convex?

So how exactly should the "visual representation" of those curves change? IOW, if you were to change each of their alignments, in what direction would you want each of their strokes to move uniformly: left, right, up, down, or maybe along some diagonal? The stroke alignment options have no meaning for any open curve because they do not completely enclose an area & therefore have no definite inside or outside. It doesn't matter which end you start from or if you choose the left or right side as a reference point as you move along it. "Left side" & "right side" do not mean the same things as "inside" & "outside" in any objective or normal real world sense. Consider for example an isolated section of curved fencing in the middle of a field that does not form a closed perimeter. How could anyone determine what is "inside" that section & what is "outside" it?

R C-R Posted March 22, 2018 Share Posted March 22, 2018 1 hour ago, owenr said: No, the arrow is always on the right as you walk along the path from start to end. If you consider the right to be the outside, then aligning the stroke to the outside will put the stroke on the side with the arrows. True, but why consider the right to be the outside? I don't think @Pšenda said that it was, only that the direction from the beginning to the end is clear & that by 'waking' along the path from beginning to end arrows could always be put on the right. You could say the same thing about putting them on the left, but I can see no compelling reason to consider either side the outside. Consider the example @dutchshader provided & it should be obvious how arbitrary that can be. Or consider this example: Even if you initially consider the concavity of the partially enclosed area as arbitrarily defining a curve's inside, later on in the project considering that same concavity as defining its inside may border (no pun intended) on the absurd. 2 hours ago, owenr said: We already can align text to one side or the other of an open path, so why are people having difficulty understanding how a stroke could be aligned to one side or the other of an open path? The alignment of a stroke to one side or the other of an open path is not the same thing as the alignment of text to one side or the other of an open path (which then has no stroke), but even if it was, the issue is determining unambiguously or at least consistently which is the inside side & which is the outside side where the text should be placed. Even if we consider only LTR languages without what implications that might have for supporting RTL ones in the future, the 'walk' from from beginning to end thing won't work & the ambiguity remains: Quote All 3 1.10.8, & all 3 V2.4.1 Mac apps; 2020 iMac 27"; 3.8GHz i7, Radeon Pro 5700, 32GB RAM; macOS 10.15.7 Affinity Photo 1.10.8; Affinity Designer 1.108; & all 3 V2 apps for iPad; 6th Generation iPad 32 GB; Apple Pencil; iPadOS 15.7 Link to comment Share on other sites More sharing options...

R C-R Posted March 23, 2018 Share Posted March 23, 2018 1 hour ago, owenr said: Obviously an open path doesn't have an actual inside or outside, but the discussion has been about stroke alignment where the choices of alignment are named as inside, outside and centre, not left, right and centre. Which is pretty much the point: they are named that way because they only affect things that do have a definite inside & an outside. Expecting anything else, whether based on path direction or anything else to arbitrarily define which side should be considered to be the outside or inside of an open curve, makes no sense to me for the reasons I have already mentioned. I can't think of any practical value for it, but if there is one someone please tell me what it is (& if considered relevant how the names should be changed to make that clearer). Without that, it just seems like an unnecessary complication that would do more to confuse than to clarify the difference between open & closed paths.
