Dear Dan,

Welcome and thank you for your help.

I've had a look at the code, it looks very reasonable for what I think the feature does. It would be great if you could make a short video showing the feature (you don't have to), I've found it easier to review new features with their ui and code with a video demonstration.

The one thing I did spot was the creation of some toolbox items, there's a lot of icons on that bar now and we might be weighing it down. but I'll know more when I can see it in the flesh.

Best Regards, Martin Owens

Ditto the thanks and welcomes!

We've just entered the release phase of the project, the implication of which is that we just happen to be frozen for new features at the moment. The good news is that the freeze should not be for too terribly long (a few weeks max I hope), so perhaps by the time your feature is through review and ready to land, the trunk will be re-opened for landings.

Thanks, Bryce

Hi again.

I know it's been a while since I did anything relating to this, I've been a little distracted. I've been trying to fix the issues that were pointed out before, this is the bug when converting a circle to a path and the lack of sensible conversion from an arc to a bezier.

Before I go any further however, I'd like to update the the latest code from upstream but I'm not sure how to do this with bzr. If I was using git then I would now run 'git pull --rebase' and fix any conflicts that have appeared. How do I do the same with bzr?

Assuming that goes well, I also need a little help adding the feature for converting from an arc to a bezier. I have the following code which runs when doing such a conversion, it generates a bezier path to insert where the arc was, but I'm not sure how to insert that new path in place of the old segment. Below is an extract from my src/ui/tool/path-manipulator.cpp, see the 'TODO' comment...

Thanks for any guidance. Dan.

/** Make selected segments curves / lines / arcs. */ void PathManipulator::setSegmentType(SegmentType type) { if (_num_selected == 0) return; for (SubpathList::iterator i = _subpaths.begin(); i != _subpaths.end(); ++i) { for (NodeList::iterator j = (*i)->begin(); j != (*i)->end(); ++j) { NodeList::iterator k = j.next(); if (!(k && j->selected() && k->selected())) continue; switch (type) { case SEGMENT_STRAIGHT: if ((j->front()->isDegenerate() && k->back()->isDegenerate()) && (j->arc_rx()->isDegenerate() && j->arc_ry()->isDegenerate())) break; j->front()->move(*j); k->back()->move(*k); j->retractArcHandles(); break; case SEGMENT_CUBIC_BEZIER: printf("To cubic bezier!\n");

if (!j->front()->isDegenerate() || !k->back()->isDegenerate()){ break; } if (!j->arc_rx()->isDegenerate() || !j->arc_ry()->isDegenerate()){ // This is an elliptical arc that is being converted to a cubic bezier Geom::Path cubicbezier_path = Geom::cubicbezierpath_from_sbasis(j->getEllipticalArc().toSBasis(), 0.1); printf("Size of path to insert: %lu\n", cubicbezier_path.size()); // ====== TODO ====== // How do I now get the contents of cubicbezier_path to // replace this arc segment?? // ==================== break; }

// move both handles to 1/3 of the line j->front()->move(j->position() + (k->position() - j->position()) / 3); k->back()->move(k->position() + (j->position() - k->position()) / 3); j->arc_rx()->move(*j); j->arc_ry()->move(*j); j->retractArcHandles(); break; case SEGMENT_ELIPTICAL_ARC: if (!(j->front()->isDegenerate() && k->back()->isDegenerate())){ j->front()->move(*j); k->back()->move(*k); }

if (j->arc_rx()->isDegenerate() && j->arc_ry()->isDegenerate()){ Geom::Point midPointOffset = ((k->position() - j->position()) / 2); Geom::Point handleOrigin = j->position()+midPointOffset;

j->arc_rx()->setOffset(midPointOffset); j->arc_ry()->setOffset(midPointOffset); j->arc_rx()->move(j->position() + ((k->position() - handleOrigin) / 2)); j->updateArcHandleConstriants(j->arc_rx()); } break; } } } } --------- Original Message --------- Subject: Re: [Inkscape-devel] Arcs in the path editor - be kind to new users. From: "John Billingsley" <john@...3371...> Date: 5/22/16 4:07 pm To: inkscape-devel@lists.sourceforge.net

I see some fascinating developments here - but many of them will baffle users who are new to Inkscape. I see below a mention that the toolbox bar is getting crowded and can sympathise strongly with that.

The first question of a new artist user is likely to be "Can the software see my pressure-sensitive pen?" Then "How can I scribble a quick sketch as easily as in OneNote?" Only when they gain confidence in the program will they look for the bells and whistles, such as node editing, brush texture, cloning, mirroring, morphing .....

I would recommend a 'first launch' distribution that shows a minimal number of tools on the tool bar, one of which could be 'add tool', so that the user can tiptoe into the more advanced options rather than being plunged in from the start. I would also recommend a diagnostic feature to show whether the pressure tablet is really seen. The tablet driver can produce two conflicting pairs of coordinates and that is another source of confusion. (You might like to see a minimal diagnostic at www.jollies.com/drawpressure.htm - though it only works with IE)

I look forward with interest to the launch of version 0.92,

Best wishes John

Thanks for the observations below, I hadn't spotted one of those bugs.

For those that requested it, I have thrown together a quick demo video here: https://youtu.be/IJ1u8puxFOM

The bug with the circle looks odd, perhaps related to the use of a 'Z' to close the path, I'll take a look at this.

I could hide some of the extra buttons in a new sub-menu next to the "Make segments arcs" button (like the "Insert node" sub-menu in the same toolbar). That might help keep things tidy.

Dan.

At least I have some time to neaten things up thanks to the feature freeze.

I'll let you know when I have a demo video available.

Please do.

The interface is a bit awkward but I don't have a better idea at this point. It would probably be useful to be able to fix the tangents at the nodes so the path is smooth at that point.

I see a couple of bugs in my five minutes of playing with it:

First one:

1. Draw a circle.
2. Convert to path (path consists of four arcs).
3. When adjusting one arc, the upper right arc is transformed into a

straight line.

Second one:

Converting from arc to Bezier (clicking the curve button) either does not work or does not produce expected result of a Bezier that approximates an arc.

Thanks. Dan.

We'll have our UI team look it over and make some workflow charts and suggestions. Looking great so far though, and thanks for the vid! Welcome to the project. :)

Sorry if I sounded i bit short this morning - mailing from mobile can be a bit too succinct at times ;)

Hope this feat makes it into 0.93 I'd really like to play around with it. On 16 May 2016 21:28, "Daniel Bailey" <d@...3396...> wrote:
