Re: [Inkscape-devel] Inkscape style connectors - usability suggestion
by Hans-Jürgen Hay 02 Oct '11

Hello Arcadie, my suggestion was to drop default predefined points, as the whole outline would be an infinite set of possible connection points. When ever a user drops an handle near to the outline, an instance of an connection point would be generated, positioned on the outline path next to the place of dropping the handle. This instance would hold a float which indicates the relative position of the connector on the given outline. eg.: float pos between 0 and 1, a value of 0.5 would define a position on the outline path half way between the start and the end of the path. This placement would be valid and appropriate even if the object gets scaled. As a result no predefined points are really necessary. One could build the outline out of different paths and maybe additional single point paths and only allow a subset of them to accept connectors, to specialize the objects behavior. But that would depend on the objects intended behavior and would be specific to the objects template.

Open SVG talk and Release notes for 0.49
by Tavmjong Bah 01 Oct '11

01 Oct '11

Hi, I will be giving a talk about Inkscape at the SVG Open conference in two weeks. The release notes for 0.49[1] will serve as the basis for my talks so it would be very helpful to have them up-to-date. If you have added a feature or are working on a feature that you plan for 0.49 and that is not in the notes, please take a few minutes and update the notes. Thanks, Tav [1] http://wiki.inkscape.org/wiki/index.php/Release_notes/0.49

Inkscape with Visio style connectors
by Martin Owens 01 Oct '11

01 Oct '11

Something that's been missing for a while is the ability to set arbitrary connection points on objects so we can use visio style workflows with connectors doing more work for us. May I draw you collective attention to this demonstration video: http://divajutta.com/doctormo/inkscape-as-visio.ogv Here I show off a workflow hack (using nautilus as a stencil) and an genuine edmun scream style code hack to 0.48x branch mod'ing the connector-context code which you can find here: https://code.launchpad.net/~doctormo/inkscape/knot-visio It works by enabling rectangles inside groups to act as child center points. Each of the items you see me drag in the video is a group and each connector is a very tiny rectangle. I hacked it like this because now transforms also transform the new connector points and the amount of code I had to modify is quite small. It also fixes a bug with connectors where connected elements when grouped would not be able to be updated. I added a parent group transform signal catch for 1 level deep which should help with that. Anyway, as a proof of concept I humbly submit this idea to the rest of the developers here for review. Best Regards, Martin Owens

Hello to all! I'm new in the Inkscape world. My intention is to slowly get involved and at some point start helping with the project. One first question. I'm receiving mails from this list but sometimes it's an sanswer to a question that I didn't receive. That confuses me. Can someone explain me why is that? Perhaps a setting in the subscription or another reason? Thanks in advance! -- /*------------------------------------------------ Fernando Lagos #54 11 4867 4726 lagosfernando( at )gmail.com ------------------------------------------------*/

inkscape + guile?

I'm interested in using Guile to write Inkscape extensions. I thought there was something like this around, but Google appears unwilling to provide me with a pointer. Is there an existing project for Guile extensions, or should I try my hand at it? -- Joakim Verona

Dear Inkscape Team. There is one option (Object Properties) in Object menu of inkscape. Can we set common Properties of all object in layer. (With CTRL+A) i want to do that type of operation. Like in inkscape we can set color or text of all selected object. Waiting for reply as soon as possible *Regards, Chaudhary Paresh*

If you're talking about diffusion curves in the idealized sense, you are right that in principle all boundary points influence the entire image, but in practice the influence usually tapers off quite quickly. However, most solvers do have a bit of a problem with actually converging to a solution, which led me to my thesis subject. One problem is that all solvers tend to give smooth solutions that sort of look plausible, so it is not immediately obvious that something is wrong. In my thesis I describe a potential solution, by using a fundamentally different kind of solver, but it's definitely not a drop-in replacement for existing solvers (at least not yet). Another way of attacking the problem is to redefine diffusion curves to behave differently. Whether there is indeed a "better" definition is very much an open question. (I couldn't view your site btw, for some reason I can't get webgl to work, possibly because my notebook hardly has anything worthy of the name GPU.)
