Feature proposal: moving nodes without moving handles
by Miguel BYRAM 02 Apr '08

02 Apr '08

Hi, I'm a Inkscape user for 3 or 4 years and first of all I want to thank and congratulate U for this program. I'm also a C++ beginner developer and I want to implement a functionality. It's about the moving of nodes. In Inkscape, at present, when U move a node toward a vector V1, his handles (bezier indicators) move with the same vector V1. What I want to do is to add the possibility to move a node with V1 while his handles move with f*V1 where 0.0 <= f <= 1.0 As if U put a spaghetti on a table, U took it near the middle and pull it up. This could be very useful to draw a sun or a hair shape. As I said earlier, I'm a C++ beginner. I just succeeded in compiling Inkscape using Eclipse under Ubuntu but I don't know where to modify, or search... even where to look at, to understand how the node's moving works presently. So here are my questions : 1. Did I made myself clear ? English is not my mother tongue (so please pardon me for faults) and before going further I want U to understand my proposition. 2. Could someone lead me or just show me where to look at to understand the Inkscape architecture and more specifically the node's moving ? Thanks. ..miguel..

NEW: "No Filters" view mode
by MenTaLguY 02 Apr '08

02 Apr '08

By popular request (and personal need) I've added an additional view mode which lies between "Outline" and "Normal"; objects retain their normal appearance except that filter effects are not applied. This is most useful when interactively drawing in complex documents and leaving filters enabled would harm responsiveness too much. Editing or tweaking existing paths is still often best done in "Outline" mode. -mental

GSoC08: Tech Drawing ideas (comments very welcome)
by Maximilian Albert 02 Apr '08

02 Apr '08

Hi, unfortunately I haven't yet received any response to my other emails, so I don't know if there is a potential mentor for any of them or if they are suitable for a SoC project at all. In any case, I have written up some thoughts regarding the facilitation of geometric constructions/tech drawing in Inkscape. They can be found here: http://www.rzuser.uni-heidelberg.de/~malbert/tech_drawing/ It's a draft and not complete yet (but all I could manage alongside studying for my graduation exam). I would very much appreciate any input/comments/suggestions/criticism. Would any of the potential mentors be willing to supervise such a project? Thank you very much in advance for any feedback, Max P.S.: I'd still love to elaborate on my 3D-related ideas but I feel they are much less straightforward to implement so I'd need advice from more experienced developers regarding feasibility/desirability and on which things to concentrate before going into more detail.

Teaser: Inkscape goes 3D
by Maximilian Albert 02 Apr '08

02 Apr '08

Hi, here is the first pay-off of my 3D box refactoring after last GSoC. I'm proud to introduce Inkscape's first diffident steps into the 3rd dimension: Perspective paths. :) The new feature is implemented as a Live Path Effect, and contrary to what I had expected it's actually quite usable. ;-) Here is a screenshot of what it looks like with some text added to the two sides of a 3D box: http://www.rzuser.uni-heidelberg.de/~malbert/images/teaser_3D_LPE.png Note that the original path is still editable (also note Johan's great new feature of highlighing paths!). The effect can take as input any path but if you want to give it a try then it's probably best to use it with text first (converted to paths, of course) because this makes it easier to interpret the visual result. Please keep in mind that it's only meant as a proof-of-concept. The UI needs to be refined, functionality to be added, and above all the perspective is not yet interactively adaptable (mainly because LPEs can't take arbitrary SPObjects as parameters); at present the effect just grabs the first existing perspective from the document. So a workaround would be to draw a 3D box, modify its perspective and reapply the LPE to the path. It should then use the updated perspective (provided that it's the first one occurring in the document defs). Have fun using this. :) Cheers, Max P.S.: Apart from my GSoC application (which still needs to be submitted) this is likely to be the last thing you'll hear from me for the next six weeks or so. I need to drastically reduce the time invested for coding and mailing list interaction (as much fun as it is), otherwise I risk my remaining exams to badly go down the drain, which I really don't want to happen.

Re: [Inkscape-devel] GSOC 2008 / Technical Drawing in Inkscape

Op Wo, 2 april, 2008 13:26, schreef Maximilian Albert: > [...] But given that snapping is a common issue > with tech drawing and CAD, I was considering to include some of it in my > GSoC proposal as more advanced features. In particular, "tangent > snapping" (of lines to curves, possibly even of arbitrary curves to each > other) would be very nice and seams quite feasible using 2geom. Currently all snapping is from a single point (node/bbox corner) to another point or to a path. Adding midpoints, circle centers, etc. is easy, as this requires only calculating additional points. Things become a little bit more complicated though when we would like to snap paths to paths, e.g. to make them tangent or perpendicular. Assuming that 2geom provides the math to find tangents and such, then it's still doable for pure translations of objects (using the selector tool). We will only have to iterate through the paths instead of through the points. But things do get complicated when objects are being scaled / skewed, or when a single node within a path is being dragged in the node editor. In these cases one of the paths is changing shape. > Since I know that Diederik is working on snapping and I don't want to > steal his work :), my question is mainly directed at him: Do you think > this is a good idea? If so, what else would you consider worthwhile (and > don't want to do yourself)? I've been working so far on the point to point/path snapping, which is nearing completion. I don't think there's much left to do there, except for some GUI related stuff (dialogs, snapping indicator, etc.), and calculating additional midpoints and such. It will probably take me a few months, but that's only because my time is limited. It is not very challenging. If you'd like to work on the snapping, then you should work on the path-to-path snapping. This will be a significant amount of work. IMO you could go either of two ways for this: - build a general path-to-path snapping framework, which is available anywhere (node editor, creating new shapes, selector tool). This is what we also have for the point-to-point/path snapping - or limit it to specific tools, e.g. perpendicular snapping only in the Freehand / Bezier tools, not in the selector tool's transformations. I think the former would be quite ambitious, don't know it it's really possible, also because I haven't thought about it very long yet. The latter would give more chance of achieving something, step by step. Diederik

Call for help: Screenshots needed for 0.46
by bulia byak 02 Apr '08

02 Apr '08

As we're nearing the release, we need more screenshots to show off the new features in 0.46, to be published at http://inkscape.org/screenshots/index.php?lang=en. Here's a page describing how to create good screenshots: http://wiki.inkscape.org/wiki/index.php/MakingScreenshots. Use the information on that page and the best of the existing screenshots in our gallery as inspiration. At the very least, we need to illustrate: - 3D box tool - SVG filters - more live path effects (we only have one screenshot for path along path) - gradient tool's on-canvas mid stops - a (meaningful) illustration of the color management at work - new extensions - new grid and guide features - perhaps something with custom markers, along the lines of http://needcoffee.deviantart.com/art/Gradients-To-Path-78650259 - any complex, stunning, impressive Inkscape art even if it does not use the new features :) See the release notes for a list of all new features: http://wiki.inkscape.org/wiki/index.php/ReleaseNotes046 You can send your submissions to me for publishing on the site. Thanks in advance! -- bulia byak Inkscape. Draw Freely. http://www.inkscape.org

Import locale problem
by Brian Vanderburg II 02 Apr '08

02 Apr '08

I've installed lxml. First I installed it into the python path for inkscape (C:\program files\inkscape\python\...) but that did not work. Apparently inkscape is using the main python install (C:\Python25), so I reinstalled it there and it worked. The scripts work now, but still have a major annoyance. The scripts constantly complain about importing 'locale'. It seems that the module search path is causing it to first find 'C:\Program Files\Inkscape\locale', and not the 'C:\Python25\Lib\locale.py'. It only emits a warning (every time the script executes), and the script still works, but it is annoying. Since I don't need the locales I just removed the inkscape locale folder, but I still figure I'd report the problem. Brian Vanderburg II
