Dashed Stroke Aligned Outside/Inside

[Ezbaze]

What Application are you using? 
Designer

Are you using the latest release version?
v2.1.1

Can you reproduce it?
Yes

Does it happen for a new document? If not can you upload a document that shows the problem?
Yes

hardware acceleration
Same issue with both.

What happened for you (and what you expected to happen)

Dashed Stroke Aligned Outside/Inside has inaccurate rounding / missing rounding for bottom - top right corners.

Is the alignment for inside / outside supposed to be disabled? ( It would be useful to be able to align a dashed stroke inside / outside ) and going further which will probably fall under feature request, it would be interesting to allow for separate rounding of each corner of a dashed stroke

That’s an interesting effect which I’ve not noticed before – see attached video.
I’ve just tried it in V1 and that’s the same too.

However, I’m not entirely sure what I would expect to see if I told the software to put the dashes on the inside of a curve.

Don’t know if this is a bug or expected behaviour.
Looking forward to hearing something from the staff on this one.

@GarryP Right now it just aligns it to outside / inside and skips the rounding of the corners that touch the curve.

 

I know that Illustrator disables the Align Inside / Outside, so the Serif team could just say that the buttons were supposed to be disabled, but considering that it's very close to what I was explaining, they could make the rounding work for the parts that are touching the curve, if that was the case then we could have something that the Ai users don't  / It could be expanded to allow for separate rounding of each corner of the dashes

I'm seeing something a bit different, on iPad with Designer 2.2.0.1881.

Aligned center: 

 

And now aligned inside, what happened to the gap?

One of the things I don’t understand is why the dashes get longer when the alignment is inside/outside; it’s probably some geometry thing that I won’t understand even if it’s explained to me in single-syllable words.
Even so, it’s an interesting effect that I don’t think should be removed unless there’s some good reason for it being so.

I don’t understand what you mean by “expanded to allow for separate rounding of each corner of the dashes”.
Specifically I don’t know what you mean by the “corner”.
Can you give a visual example?

[Ezbaze]

@walt.farrell Yes, I have noticed it as well, the length/spacing of the dashes also brakes when switching the alignments

I think that’s what we are seeing – the ‘dash’ gets longer somehow so the ‘gap’ closes up.

Here is a partial visualizer I made using rectangles as each dash

This represents the rounding of the bottom left/top right corner of a dash being at 50% each, this could also allow the use of the different corner types that are already in use for the corner tool / rectangle

 

If they were to allow for the Inside / Outside Alignment, technically it would break the current effect as they would have to make the corners rounded to make it consistent but the ability to make the rounding separate would allow for the recreation of the current effect as well as fix the current issue

Ah, thanks, I see what you mean now – a bit like how we can create/maintain rounded rectangles with different corners.

I think that would be a nice addition to the functionality but I imagine the UI could get rather messy.

I think one other potential barrier with doing that is whether that sort of rounding can be exported into the various vector formats.
For example, if SVGs can’t handle that kind of thing then the export process would start to ‘break’ as curves would have to be expanded at the point of export and that might not be what the user wants.

Yes, it would require an extra row for the corners, but I don't think that it would be an issue as it would just be for the Dashed Stroke style:

 

For the export, I think that would fall under unsupported features and would be converted to curves ( SVG ) / rasterized on export

I've added this to a report we currently have logged.
