GTK+ on Native OSX Update
by Derek Hinchliffe 31 Jan '08

31 Jan '08

Hi all, Apologies if this has been posted already, I haven't been keeping up with the list of late. But I thought those of you tracking the progress of the native GTK+ port to OSX might be interested in the following blog post from Mikael Hallendal from Imendio. http://micke.hallendal.net/blog/2008/01/30/happenings-in-gtk/ Quote: "Our aim is to have an easily installable framework for Mac OS X finished within the next couple of weeks to make it very easy to setup your Mac OS X machine for cross platform application development with GTK+." This is good news, as although it looks like the port still has some way to go before it is production ready, getting a framework build out there will greatly simplify testing apps like Inkscape and finding bugs. Cheers Derek

NEW: Corel DRAW X4 and Zoner Draw 5 keyboard profiles
by Alexandre Prokoudine 31 Jan '08

31 Jan '08

Hi, Sorry guys - I couldn't resist adding a new feature during feature freeze :) First shot at keyboard profiles for Corel DRAW and Zoner Draw has landed into trunk. I'll try improving bits here and there in he next days, but current version should be good enough already. Also, Adobe Illustrator profiles has been fixed and improved. If I'm lucky with spare time, I'll try adding another one for ACD Systems Canvas 11 too. P.S. In case you don't know yet, work on Corel DRAW X4 file format support in UniConvertor is ongoing and new release to add this feature is planned *real soon now* ;-) Cheers, Alexandre

filter node parameters UI
by Felipe Sanches 31 Jan '08

31 Jan '08

I have noticed the need for a way to configure x,y,width and height for the filtered area. These are paremeters of the <filter/> node. I am trying to code it but I got some problems that I was not able to solve. Maybe you can help me. Please take a look at this patch. It substitutes the original _settings_box by a Gtk::Notebook with 2 tabs. In the first tab we have the filter primitive settings. In the second tab I have put the filter settings (x,y,width and height) My doubts are: 1) am I coding correctly the setting of filter node parameters? 2) why doesn't the filter node parameters start hidden as it happens with the primitive settings? 3) we have some problem with the labels of the filter node settings. Could you please review this patch? It would be great to see this on pre1 release which seems to be scheduled for tonight. And it is certainly necessary for 0.46! best wishes, Juca PS: I also thought it would be cool to have these being adjustable by handles on canvas maybe, but that's not the case by now. Maybe we can work on this possible enhancement in a future version of inkscape.

As with the past few contests we've had, it is being done on DeviantART ( http://www.deviantart.com/ ). You can find out more about it at: http://inkscapers.deviantart.com/journal/16631247/ If you're interested in finding out more about our presence at the conference, which includes a booth, a birds of a feather session, and four one-hour classes that I will be teaching, you should read that journal entry at the URL above. If you live in the greater Los Angeles area (or elsewhere) and are able to make it, we'd love to see you there! Cheers, Josh

Debugging under OS X
by John Faith 30 Jan '08

30 Jan '08

Hello, I was chasing a startup crash on OS X 10.3.9 and after some difficulty I found a way to get a backtrace from gdb. I hoped this to be simple, but possibly due to the fact that on OS X the Initial launcher app calls a script which calls a script which calls the actual binary, I think gdb got confused. Where is a good place to document this, assuming this or something better is not already written down? This page?: http://wiki.inkscape.org/wiki/index.php/DebuggingTips , John

grid arrange => table?
by bulia byak 30 Jan '08

30 Jan '08

While we're not in a string freeze yet, would anyone complain if I rename Grid Arrange dialog to Table? Grid has another meaning in Inkscape, and I think Table best describes what this dialog does. -- bulia byak Inkscape. Draw Freely. http://www.inkscape.org

Keep path's custom informations after a boolean operation
by Gorse Emmanuel 30 Jan '08

30 Jan '08

hye, (i've already post this in the forum but i think it's more appropriated to post it here) i'm the inksmoto main developper (xmoto level editor which is an inkscape extension look at that to see the different possibilities: http://wiki.xmoto.tuxfamily.org/index.php?title=Inkscape-0.4.0 Xmoto is a gpl game: http://xmoto.tuxfamily.org/ ) some times ago, Ted told me that: "What I would recommend for this is add a custom X-moto namespace on the XML file. Inkscape will honor this, and keep it in the file. So something like this: <path d="M 1 1 M 2 2 M 3 3 z" xmoto:vertex-settings="rrg" /> Where 'r' and 'g' mean something about the vertexes of the path." So i add some path information in my own xmoto namespace: <path ns0:xmoto_label="edge:downtexture=street|edge:texture=street" id="rect2388" d="M 314.29911,415.20982 L 314.29911,98.084821 L 128.58036,98.084821L 128.58036,415.20982 L 314.29911,415.20982 z" style="stroke-linejoin:miter;stroke-opacity:1;fill-opacity:1;stroke:lime;stroke-linecap:butt;stroke-width:1px;fill:#66ddaa" /> with the namespace definition: <svg xmlns:ns0="http://xmoto.tuxfamily.org/" (the name ns0 is automatically choosen by lxml) But, when i do a boolean operation on this path, my ns0:xmoto_label disapeared in the new paths created after the boolean operation... <path style="fill:#66ddaa;fill-opacity:1;stroke:#00ff00;stroke-width:1px;stroke-linecap:butt;stroke-linejoin:miter;stroke-opacity:1" d="M 575.875 242.375 L 390.125 242.375 L 390.125 423.9375 L 575.875 423.9375 L 575.875 242.375 z " id="path3184" /> <path style="fill:#66ddaa;fill-opacity:1;stroke:#00ff00;stroke-width:1px;stroke-linecap:butt;stroke-linejoin:miter;stroke-opacity:1" d="M 390.125 106.8125 L 390.125 242.375 L 575.875 242.375 L 575.875 106.8125 L 390.125 106.8125 z " id="path3179" /> i've tried with both inkscape 0.45.1 and 0.46 svn from yesterday and the behaviour is the same... is there a way to keep my informations after a boolean operation ?? (i've also tried putting my informations into inkscape:label, but it's dropped too after a boolean operation) (and i also confirm the notebook bug, i've having it too with 0.46svn https://bugs.launchpad.net/inkscape/+bug/169017 ) regards.

Pencil tool interpolation
by R M 30 Jan '08

30 Jan '08

Hi all, I've been having trouble getting lines smooth looking when drawing with the pencil tool. Looking at the code, it seems like a reasonable job of interpolation is being done, but it is done while the path is being drawn, so it can't base the interpolation on all the points drawn by the user. I made some changes to do the interpolation of the entire path on button release: Here is an example using identical mouse points and identical tolerances: http://arcsin.org/temp/Screenshot-3.png On the left, is the current way; on the right, is the path interpolated using the entire curve. Deferring interpolation decreases the number of knots created and improves (imo) the result appearance. The tolerance is still adjustable in the same way it is currently. Here's the diff, which is only a demonstration, and in no condition to be actually used: http://arcsin.org/temp/diff In order to make the final patch, i guess the questions are ... is the way i'm saving the points ok (or should i use std::vector, etc), should we forgo interpolating at all during drawing and instead just show the user a line path (which would greatly simplify the pencil-context code)? or do people want to retain the old behavior and create a new setting/tool. regards, rob
