Assigning bugs to me in Launchpad

Hello I noticed that a few bugs were assigned to somebody with an account called "krzysztof kosinski (krzy-kos)". I would like to point out that it's not me, and I'm not receiving notifications about this. My account is called "Krzysztof Kosiński (tweenk)". Maybe we could put such information here? http://wiki.inkscape.org/wiki/index.php/Contact_information Regards, Krzysztof

Failed building
by unknown＠example.com 31 Jan '10

Trunk doesn't build anymore after the latest changes concerning updated devlibs. Where should we find these updated devlibs? Apparently not in the usual SVN. Reverting 9036 and 9037 soon... -johan

[PATCH/RFC] New feature: Enclose objects in groups when applying mask
by Martin Sucha 30 Jan '10

30 Jan '10

Hi all, I prefer adding objects into a group before applying a mask, because it allows me to manipulate masked content easily without unsetting mask. But I often forget to group objects before I apply a clip/mask. So I decided to take a look at inkscape source code and made this little feature that does it automatically for me. It needs one more thing to work properly though - when automatically enclosing each object in a group it should mark that group as made by that feature so when unsetting mask it ungroups only those automatically added groups. So where should be stored some info about whether this group should be automatically removed? There are two possibilities that I think of: either inkscape:groupmode attribute or custom attribute for this purpose Also, is it sufficient to manipulate those attributes directly or is there any class that takes responsibility for this? At least there is some code managing inkscape:groupmode attribute, right? I've added a new checkbox in Inkscape Preferences/Clippaths and masks called "Enclose masked objects in groups" to activate this feature (disabled by default to be consistent with previous behavior), so don't forget to check it before testing ;) As I'm not very familar with C++ or Inkscape source code I hope I've not introduced any memory leaks or crashes. Also if you find any coding style violations, please notify me. Patch attached. Any comments are welcome ;) Best regards, Martin Sucha

pdf-parser.cpp:812: error: no matching function for call to 'GfxColorSpace::parse(Object*)'

I'm seeing a compile error in my Gentoo Linux ebuild tracking inkscape trunk.

Inkscape & Dbus
by Bryan Hoyt | Brush Technology 28 Jan '10

28 Jan '10

Could somebody bring me up-to-date on the state of the new Dbus interactive stuff in Inkscape? I remember seeing a news post or wiki page about it, and I was quite excited. It looks like the best (only) way to make interactive, real-time plugins for Inkscape -- and lots of other fun stuff. But I can't find much on it now. Nothing turns up on a news search or a wiki search. One thing I'm thinking of is trying to write the PixelSnap plugin to be more real-time. - Bryan

Hey All, Google announced that they will be doing Summer of Code again this year. We can apply to be a mentoring organization again on March 8th. I'm willing to be the Administrator again if no one else is interested. Cheers, Josh

Missing file on make command
by Karlisson 27 Jan '10

27 Jan '10

Hi everyone, on revision 9020, before 'make' or 'make clean' can run, it stops and says it need the file 'm4/ink_svn_snapshot_build.m4' (with the 'SVN' on the filename). If I switch the 'svn' to 'bzr', it gives me the same error, saying it needs the 'm4/ink_bzr_snapshot_build.m4'. I could fix the problem and run 'make' by copying the file and renaming it to m4/ink_bzr_snapshot_build.m4, so, there's a file somewhere needing an update :) Thanks! -- Karlisson M.

Fwd: Set new coordinates for points in thePiecewise<D2<SBasis> > array
by Anton Moiseev 26 Jan '10

26 Jan '10

Hello, > I haven't read your mail in much detail, but generally it is a very bad idea to directly modify nodes of a path. > Could you exp > Actually, the effect is live version of "perspective" extension. The input is rectangle with modifiable by user nodes (which is originally generated from the object bounding box), the result - the object would be inscribed into modified rectangle, so it would look like in perspective. I am not aware if this problem has a solution based on some kind of generic coordinate transform formula, which could be applied to the whole Piecewise object, so I use my own solution of the problem based on straight-forward linear geometry, which calculates new position for each object's point and then tries to apply this value to the original point - as if the user used "node editor" tool to move points to the places where he wants to. I can try to describe the algorithm in more details if that makes sense. I know there is experimental perspective_path live effect which also works with perspective, but when I tried it, it appeared that it works in some different way - it does not use bounding rectangle to setup perspective, but relies on object resize/movements instead, so this is not what I need exactly. I also looked at the perspective.py code, but it seems that python extensions work in a bit different way than live effects, so I could not neither reuse it as is, nor understand its formula basing on source code without comments. thank's Anton

Set new coordinates for points in the Piecewise<D2<SBasis> > array
by Anton Moiseev 26 Jan '10

26 Jan '10

Hello, I'm trying to write a new live effect which would move original path points to new locations. I have taken lpe-envelope.cpp for the base and write my code inside Geom::Piecewise<Geom::D2<Geom::SBasis> > LPEPerspective::doEffect_pwd2 (Geom::Piecewise<Geom::D2<Geom::SBasis> > const & pwd2_in) so, I receive Piecewise<D2<SBasis> > at the input and want to return generated object Piecewise<D2<SBasis> > at the output, which would contain all orinal pwd2_in points, but with new coordinates. Generally I did not have problems with my algorithm and I have an array of Point objects, but now when I want to put them back to Piecewise<D2<SBasis> > array, the result does not have the required quality: It is hard to explain in more details, so would try to put some code I have. Piecewise<D2<SBasis> > output = pwd2_in; // this gives me a path with same number of nodes as the original one then I go though all points in the path and try to set new location for each point for (unsigned i = 0; i < pwd2_in.segs.size(); i++){ Point target_point = XXX; // calc new value for current point output[i][0][0][0] = target_point[0]; // set value for x output[i][1][0][0] = target_point[1]; // set value for y } return output; With code which works in this way the transformation converted any the object to invisible phantome (the selection showed its area with nothing inside, but when remove the selection it is not possible to select object again, also the "edit points" did not show any objects) - in short, the result was broken. Then I played a bit with printing values for pwd2_in path, understood that I must somehow play with SBasis object values (set values to SBasis[0][0] and SBasis[0][1]) and added the following to the code: for (unsigned i = 0; i < pwd2_in.segs.size(); i++){ Point target_point = XXX; // calc new value for current point output[i][0][0][0] = target_point[0]; // set value for x output[i][1][0][0] = target_point[1]; // set value for y if(i > 0) { // setup previous point target value output[i - 1][0][0][1] = target_point[0]; output[i - 1][1][0][1] = target_point[1]; } else { output[i][0][0][1] = target_point[0]; output[i][1][0][1] = target_point[1]; } } return output; That was much better - I was able to see the deformed objects which looked much like originals, but still had some issues: 1. Bended curves became straight lines 2. I have problems with objects consisting of multiple paths Actually, the 1st point only shows itself when I try to deform such object as symbol '3' (converted to path) - after deforming its shape looks like original, but consists of straight lines; though when I deform a simple triangle with one rib curved,the curve does not disappear, but did not test much though with this deffect. The 2nd problem for now is more important - it is visible after deforming symbol '4' - when it is converted to path, it consists of 2 unconnected path objects, and after my deforming, those 2 paths become connected at some point. This is definitely happens because I set incorrect values to SBasis[0][1] and actually I would prefer not to play with SBasis object by hands and to do my task in some other more reliable way, but for now I could not find anything relevant in the documentation. thank's
