win32 build working again
by Bob Jamison 08 Apr '24

The win32 build, which was broken for the weekend, is working again. I just made a "manual autobuild" again, so that we can see how it looks on Windows: http://troi.titan-aeu.com/~rjamison/inkscape/builds/ Bob

LPE dropdown box (was : NEW: LPE Interpolate)

>> The LPE choose dropdown box is getting really huge now. Who wants to >> make mockups of what is a better system for applying effects? > > What about just a hierarchical menu with submenus, similar to the Effects menu? I think this is an issue that needs more to be discussed before coding anything (search for filters ?) Here is a first draft for LPE submenus, please comment and modify : =Artistic= // Everything that changes the path style (on a visual point of view) Freehand Shape Interpolate Sub-Paths Pattern Along Path Sketch Stitch Sub-Paths =Create= // create a very different path Gears Spiro spline ?

Smooth transitions in Bézier paths
by Diederik van Lierop 11 Nov '08

11 Nov '08

Hi, I hope you don't mind if I increase the traffic on inkscape-devel even more ;-) At some point an idea popped up to only snap to nodes at discontinuities in paths, and not to nodes at smooth transitions from one Bézier segment to another. This is more intuitive (less "Hey, what it is Inkscape snapping to now?") and might increase performance. Problem is that in the object-snapper I only have access to SPCurve, which is a wrapper for "old-style" NArtBpath. It's easy to find out whether a point is inbetween two Bézier segments, but how do I find out if a transition is smooth? I guess that should be done by comparing the control points, or is there an easier way? With the transition to lib2geom, will the NArtBpath be deprecated in favor of the Path class? (that would make this rather exercise useless in the long run). Any pointers would be appreciated here, Diederik

question regarding wishblade robocraft support...
by stuart 03 Sep '08

03 Sep '08

Sorry for posting here if the user list if better. And sorry about the subject if it has been talked about before. I couldn't get sourceforge to add me to the inkscape user mail list and sourceforge was timing out on all my archive searches with no results. --- I remember reading that there was a patch or something to inkscape to support wishblade and robocraft users. Has that been integrated into the inkscape application? Is that what the DXF is all about? Wishblade users can not use DXF directly (needing the robocraft software to import DXF and change it to some sort of native (and maybe proprietary) GSD). Is there a way to get inkscape to save images in GSD in order to simplify the process? Ideally, I would prefer to skip bringing up the wishblade application. In my set up, I do all my work in linux (GIMP/INKSCAPE) and only the plotting in Windows. If I could do everything in linux it would simplify the flow of work greatly. Has anyone figured out how the craftrobo is communicated to in order to use it with common open source linux plotting software? Better yet, has anyone figured out how the wishblade has been crippled in order to use it with common open source linux plotting software? ...thanks

sorting out PS/EPS/PDF export mess
by bulia byak 03 Sep '08

03 Sep '08

It's always bad when the UI offers two ways to do the same thing without really explaining what's the difference. It's equally bad when UI uses some meaningless techno jargon such as "cairo" :) Unfortunately 0.46 was released still in the middle of a transition period which made both these evils inevitable. Now that we're in 0.47, however, I would like to address this issue by switching all of PS, EPS, and PDF output to cairo, removing the builtin Inkscape exporter, and purging the mentions of "cairo" from the UI. As a matter of fact, this has already partially happened (not sure who did this). Right now both PS export options work via cairo and produce identical output. The Inkscape-native PDF export is nowhere to be seen. The only exporter which still uses native code is EPS. However, since 1.5.2 cairo can produce EPS files too, so this can all be done in one place now (closng several EPS export bugs along the way). The only downside is that it will require cairo >= 1.5.2, is everyone OK with that? By the way, the latest cairo 1.5.12 finally fixes the bug where zooming in too closely in Outline mode produced messy broken lines. Now everything is neat and clean. Upgrade is recommended. -- bulia byak Inkscape. Draw Freely. http://www.inkscape.org

python: example in wiki
by Daniel Hornung 07 Aug '08

07 Aug '08

Hello, I hope this list is the correct one for this kind of question: Has anyone managed to get http://wiki.inkscape.org/wiki/index.php/PythonEffectTutorial to work without major changes? It failed for me both on a gentoo system and on a pretty vanilla Ubuntu 8.04 box. I don't know if I will find the time to edit the wiki page according to the current lxml behaviour, but I might give it a try. Additionally Ishmal(I think) said on irc/jabber that lxml might not be used in the future anymore anyway. Now for the list of problems I encountered: * Simply making the file executable and putting it into ~/.inkscape/extensions/ is not sufficient, it won't find inkex there, but no problem, simply add import sys sys.path.append('/usr/share/inkscape/extensions') # or another path, as appropriate for your installation to the top of it. A minor problem. * All the getElementsByTagName, getAttribute, createElement,... methods are unknown to lxml, at least in the versions here (1.3.6). Inkscape returns the python error message ending with: File "/home/dhornun/.inkscape/extensions/helloworld.py", line 32, in effect svg = self.document.getElementsByTagName('svg')[0] AttributeError: 'etree._ElementTree' object has no attribute 'getElementsByTagName' If this is not a problem on the distributions' side, those can probably be fixed by adapting the code to reflect lxml's current API. Thank you very much for any useful advice! Daniel -- GMX startet ShortView.de. Hier findest Du Leute mit Deinen Interessen!

cutter control discussion
by Patrick 06 Aug '08

06 Aug '08

I have not seen any posts on this topic for a week or so. I would like to help but I am terribly slow to get things done. I am just wondering if we could hammer out what needs to be done so I can add it to my "to-do list" volume 3 I could buy a cutter in July or August and I should be able to finish reverse engineering the command protocol sometime in the fall. I know there are different formats used to send information to the cutters, would it be good to work on a more robust DXF export option too? I don't know the first thing out GSD, does does someone want to work on this ? I am unfamiliar with Inkscape internals, if I provided the commands could someone integrate this into Inkscape? Or do we even want to do this? Is there a better way? Thanks-Patrick

PS and PDF: Print/Save As
by Tavmjong Bah 04 Aug '08

04 Aug '08

Hi, I have been trying to understand Inkscape's PS and PDF output with v0.46. It is very confusing so I thought I would summarize what I have found in a table. I tested the various ways to get PS and PDF output with: http://tavmjong.free.fr/INKSCAPE/MANUAL/images/SVG_TESTS/svg_test.svg . Save As Print Cairo Vector Raster# PS PS% PDF PS PDF PS PDF Patterns No Wrong No Wrong Wrong Yes Yes Clipping No Wrong No Wrong Wrong Yes Yes Masking No No No No No Yes Yes Transparency No Yes Yes* Yes Yes Yes Yes Dashed Lines Yes Wrong Yes Wrong Wrong Yes Yes Gradient on Stroke No Yes Yes* Yes Yes Yes Yes # Only at 72 dpi regardless of DPI setting. % Crashes when run from window manager but not command line. * Displays OK in Acroread, not with Evince 0.8.2. The "Save As" and "Print" PDF use two different Cairo routines. What is the history of this? It seems to be a bit of a waste of effort. Tav

Re: [Inkscape-devel] [Inkscape-user] Snap to grid when pasting

I might just as well create something similar again, but I'm not sure how it should work. Given an object with lots of nodes, which node should snap to the grid? If all nodes were already aligned to the grid when copying, then while pasting snapping any node to the grid will do. But this will not be true in general and there will be nodes both on- and off-grid. Besides, we can now have multiple grids simultaneously, which one should we use? If we know where the clipboard data was originally located (I don't know if that information is stored), then we might paste at a multiple of the grid pitch (strictly spoken: that is not snapping, but it will achieve what you're looking for). Comments anyone? Diederik
