Open and import dialogs are "old" style on pre4-2 on winXP. Is that expected?

GSoC 2008: Student Application Deadline
by Aaron Spike 30 Mar '08

30 Mar '08

The deadline for student applications for Google Summer of Code 2008 is steadily approaching. I've seen nothing but fantastic ideas here on the list this year. If you are a student and you haven't posted an app to the list yet, don't be bashful and don't let that discourage you from applying. I encourage all students to finish up your proposals and be careful to submit them before the deadline: March 31: 5:00 PM PDT / 00:00 UTC April 1, 2008 Many students have already submitted their applications. We thank all of you for that. Good luck to all. Aaron Spike P.S. I've attempted to copy this to the email addresses from the list for every student who posted but hasn't yet submitted an application. I sincerely apologize if I missed you. Please be sure to submit your app!

I see that a Leopard dmg package for Inkscape 0.46 is posted, but not a Tiger (OSX 10.4.11) version, and the Leopard package doesn't run on Tiger. I won't be upgrading my Macbook to Leopard for a while, if at all, and would like to upgrade to the latest Inskcape. Is anyone planning to make a Tiger dmg?. If not, and the build system is fairly-well automated, I could try to build a Tiger universal package on my macbook, I have xcode etc installed. Any advice on this? duncan

Speed up the build?
by Maximilian Albert 30 Mar '08

30 Mar '08

Hi all, I'm not sure if I already asked this some time ago (if so, please bear with me). Compiling and linking always takes a considerable amount of time and I regularly run into the need to test the effect of several small changes in quick succession. Is there a way to speed up compiling in any way, for example by deactivating certain things which have nothing to do with the code I'm interested in? Any options for ./configure (I already use --without-inkjar), any compile switches, #ifdefs I'm not aware of, anything? Thanks, Max P.S.: I do use ccache but I still hope that the building (in particular, the linking) time can be reduced by other means, too.

[inkscape-devel] Candidate Proposal for GSoC 2008 Application
by Marco 30 Mar '08

30 Mar '08

I am going to submit the following proposal for GSoC, so if you have some suggestion or some critique, this is the time to tell me your opinions. I'd like thanking Nathan Hurst for his help in getting a more insight into lib2geom codebase and for the support that he provided in making my proposal more complete. After speaking with Maximilian Albert we concluded that our proposal can advance in parallel without having overlaps, moreover I'm glad to provide any further clarification. Please tell me about english language mistakes, too ! Best Regards, Marco Cecchetti =======================PROPOSAL START============================ Name: Marco Cecchetti Project: lib2geom development Abstract Lib2geom will become the core geometric library of Inkscape and it is already an open source project on its own. My project aims to expand the library and give evidence of its skills through the implementation of ad hoc "toys": little interactive applications showing off the power of lib2geom. Goals (1) Provide direct support for basic geometric shapes, so making easier the development of educational and technical geometric tools. (2) Implementation of a new curve type that fulfils the traits of a SVG Elliptical Arc and of an "Elliptic Toy" for testing and playing with this curve type. (3) Deploy a "toy" showing off a deformation effect based on the thin plate spline method. Note: the achievability of this task is subject to the time left after having fulfilled goal 1 and 2 and to the ability of building a stable and computationally feasible algorithm implementation of the thin plate spline method. Details (1) In order to simplify the implementation of technical drawing tools or the development of a geometric educational version of inkscape, I think that it is useful to have direct support in lib2geom for simple geometric objects such as (infinite) line, ray, angle, triangle, regular poligon, circle, ellipse, arcs and the availability of geometric construction methods for such objects: parallel line, perpendicular line, angle bisector, circle by 3 points, circle by 2 points and tangent to a line, circle by a point and tangent to 2 lines, conic by 5 points. This should be considered a minimal set of implementable features. (2) I'll provide the SVGEllipticalArc class with a complete implementation of all methods inherited by the abstract Curve class such as bounds computation, evaluation for a given parameter value, conversion to and from a s-power basis path, make up of a reversed arc, extraction of a sub-arc, derivative, and arc transformations. Finally there will be the ability to modify the characterizing parameters: initial and final point, rays length, x-axis inclination angle, large-arc and sweep flags. The Elliptic-Toy will provide the ability of interactively placing the initial and the final arc points, moreover moving the centre of the ellipse, upon which the arc lays, will cause the modification of the length of the ellipse rays and a further point will be used to increase and decrease the inclination of the x-axis. Finally the Elliptic-Toy will offer the possibility to set and unset the large-arc and sweep flags directly. (3) The thin plate spline (TPS) is the 2D generalization of cubic spline. TSP is a valid tool for making up a continuos warping deformation effect. Its drawback is that it is computationally expensive both to make up the interpolating function and to evaluate such a function on the set of all the input paths. Achieving an implementation computationally affordable requires to utilize ad-hoc algorithms. So there will be the need for: - a phase of analisys based on the study of some articles [1],[2] - one or more pilot-implementations to analize the stability and the computational costs of the designed algorithm - deployment of a toy which allows to play with the developed algorithm in a similar way to the already implemented 2dsb2d toy. About me I am a student in mathematics (University of Pisa, Italy) I am always been keen on computer graphics and I am interested in computational geometry. My main programming language is C++, but in the past I also programmed in pascal, fortran 90, assembler, java, javascript, actionscript, bash script. Moreover I am knowgeable about several Boost libraries, XML APIs and the Scalar Vector Graphics Markup Language. Contributions to open source projects I'm developing an extension of Boost.Function [3] in order to implement a model of function concept supporting multi-signature and so overloading. [4] I contributed in the development of a proof of concept svg import filter for Open Office. This import filter has been developed mainly by Fridrich Strba at Novell, my contribute consists in having added svg text element support to the import filter. [5] After getting in contact with the inkscape community I have browsed a lot of 2geom source codebase and started developing a proof of concept implementation of an SVG Elliptical Arc class and a related toy.

Re: [Inkscape-devel] Tiger packages
by unknown＠example.com 30 Mar '08

(trying to build a Tiger osx package) I followed the instructions in http://wiki.inkscape.org/wiki/index.php/CompilingMacOsX and also installed gtk-clearlooks I used ./configure --disable-static --enable-shared --prefix=/path/to/build/product --enable-osxap --enable-inkboard. I produced an Inkscape.app but it does not run. Loading it manually from an xterm gives macbook:~/inkscape-0.46/packaging/macosx/Inkscape.app/Contents/MacOS duncan$ ./I nkscape 2008-03-29 10:52:34.418 defaults[9262] The domain/default pair of (kCFPreferencesAnyApplication, AppleAquaColorVariant) does not exist 2008-03-29 10:52:34.435 defaults[9263] The domain/default pair of (kCFPreferencesAnyApplication, AppleHighlightColor) d oes not exist Then it hangs. Its not clear how to diagnose what the problem is. Also, the Wiki is written assuming one is using svn. I am using the official 0.46 release tarball, and have no idea whether what I would get by using svn is that or some slightly different version. I would like to produce an EXACT copy of whatever the "official" release for LEOPARD is (exactly the same options, library dependencies, etc) except built on TIGER. Is it possible to get the precise build instructions that were used for the Leopard Inskcape.app so I can run them on tiger. (I dont want to make decisions about whether to use e.g. --enable-inkboard )? One issue I saw when building the .app was cp: /opt/local/lib/gtk-2.0/2.10.0/loaders/*.so: No such file or directory I'd try to produce a Tiger universal Inkscape-0.46 dmg for general distribution if the OS X packager no longer has a Tiger/Intel installation to work with, but I need an authoritative recipe for doing it using the official release tarball. I assume using MacPorts is the the way to get the various gtk libraries, so I installed it and the recommended packages, but want to make sure I also produce a dependency-free Inkscape.app that doesnt relay on any external libraries except those that come with Tiger and Tiger/X11 (I will remove Macports as soon as the compilation is successful, as I use Fink). duncan -------------- Original message from Bryce Harrington <bryce@...1798...>: -------------- > On Wed, Mar 26, 2008 at 03:24:38PM -0400, Jamie Kimberley wrote: > > I was building on tiger until a few weeks ago (just got a new macbook). > > I'll see if I can compile and package the 0.46 code tonight. > > > > If you want to try it yourself the instructions on the wiki using > > macports are pretty easy to follow.
