proposed patch for Spiro spline LPE
by Alvin Penner 19 Aug '09

19 Aug '09

this is a follow-up to LP Bug 415079. https://bugs.launchpad.net/inkscape/+bug/415079 I'd like to propose a patch to deal with occasional (multiple) circular loops in the Spiro Spline LPE. The patch consists of a re-application of a common clamp which is normally applied to the angles, but which appears to need to be re-applied at the final stage of the calculation. I've tested this offline in a standalone calculation to confirm that it works. I wonder if someone would be willing to test this directly in Inkscape. http://www.nabble.com/file/p25015469/spiro.diff spiro.diff -- View this message in context: http://www.nabble.com/proposed-patch-for-Spiro-spline-LPE-tp25015469p250154… Sent from the Inkscape - Dev mailing list archive at Nabble.com.

matrix isScale and isRotation do not work
by bulia byak 18 Aug '09

18 Aug '09

This seems to be a cosmetic bug but it's not: https://bugs.launchpad.net/inkscape/+bug/415168 because the undo comment depends on 2geom matrix functions: if (_current_relative_affine.isTranslation()) { sp_document_done(sp_desktop_document(_desktop), SP_VERB_CONTEXT_SELECT, _("Move")); } else if (_current_relative_affine.isScale()) { sp_document_done(sp_desktop_document(_desktop), SP_VERB_CONTEXT_SELECT, _("Scale")); } else if (_current_relative_affine.isRotation()) { sp_document_done(sp_desktop_document(_desktop), SP_VERB_CONTEXT_SELECT, _("Rotate")); } else { sp_document_done(sp_desktop_document(_desktop), SP_VERB_CONTEXT_SELECT, _("Skew")); } and these are quite fundamental to Inkscape operation - if they are broken I'm afraid to think what else might be broken. Can someone with a good grasp of 2geom or just geometry please look into this? I think this must be fixed before the release. -- bulia byak Inkscape. Draw Freely. http://www.inkscape.org

The case of the empty status bar/notification region...
by Tavmjong Bah 18 Aug '09

18 Aug '09

Hi, I just noticed that the status bar, aka notification region is often empty. I click on the Rectangle tool and see the text "Drag to create a r". I then move the cursor over the text, expecting to see a tool tip with the full text of how to use the Rectangle tool but all the text disappears. After doing this a few times I realized that passing over the swatches causes the status bar to show the name of a swatch (new feature in 0.47); when the cursor leaves the swatch area, the Rectangle text doesn't reappear. This makes it impossible to read the full text in the status bar for any tool (except the Tweak tool, where the text is restored) unless one make an end-around the swatches (difficult in full-screen mode). Can this be easily fixed? Tav

Myself I learned a > lot from Niko Kiirala's files which sit in Inkscape Samples directory. Excellent idea. I'm not very familiar with the guidelines for doing so though (I usually just work on the code). Anything I should be aware of? I assume the file should go into share/examples? > Otherwise I could also include them with your comment inside my > experiments repository file on OpenClipart (when I will be able to > upload it again because OpenClipart has some problems at the moment), or > perhaps in a separate dedicated file, or perhaps could you open a page > yourself for this kind of things ? I was thinking of creating a wiki page or something on the general techniques, as I think they can be of broader interest. I'll have a look this weekend if I can write up something.

Nodetool problem?
by Thomas Holder 18 Aug '09

18 Aug '09

Hi, with svn rev 22105 (and 22073) I get unexpected node selecting behavior. So far I can reproduce: * draw first path * draw second path * switch to node tool * click on first path * click on some node Result: two nodes instead of one get selected and the mouse cursor does not switch to normal arrow when hovering to toolbar. Inkscape also froze (100% CPU for some minutes until I killed it) twice after such incident. rev 22044 is fine, so the fix for bug 168780 might have broke this. Thomas

Question about file opening function
by Mat 18 Aug '09

18 Aug '09

Hi, I want to call a funtion to open a file. I find the three function: sp_file_open_dialog(*parent, NULL, NULL); sp_file_new_default(); sp_file_open( path, NULL)； But when I call these funtions in another thread, it crash inkscape. Is there any required initialization before I call these this function? My program block is like to : ==== bool InkDBus::openFile(const string& path){ bool result = true; bool create_new = true; list< SPDesktop* > desktops; list< SPDesktop* >::iterator iter; inkscape_get_all_desktops(desktops); iter = desktops.begin(); SPDesktop* desktop = *iter; Gtk::Window *parent = desktop->getToplevel(); sp_file_open_dialog(*parent, NULL, NULL); return result; } ==== Thanks first for reading this letter :-) sincerely, Mat.

Inkscape scripting API (Draft)
by Glimmer Labs 18 Aug '09

18 Aug '09

Here is the first draft of a Dbus based Inkscape scripting API: http://www.cs.grinnell.edu/~bergsore/inkscapeDbusRef.html (Many thanks to the ConsoleKit team for the scripts and build system I used to generate this documentation.) I would welcome any comments or criticisms, the interface is very much still up in the air so any suggestions, from small changes to major issues, would be welcome. I would particularly like to hear if people think that this would potentially support the ways in which they use Inkscape, or whether there are use cases this doesn't address. If there are lots of uses that this interface does not support, additional interfaces geared towards different users could be added. (In fact there was originally one more interface than there is now, see document_new() for details.) If you like the current API (in general) feel free to suggest additional functions or functionality. Finally, how would you like to see this extended? Dbus has proven to be quite responsive and robust for this application. How would you build off the basic platform of the Inkscape application interface? I will keep the posted link updated as I make changes based on peoples feedback. -Soren

Cross software User Interface
by Brian Vidal 17 Aug '09

17 Aug '09

Hi there, we are starting a huge project in order to take advantage of some applications UI re-design: we want to make a huge UI redesign in the best opensource design, authoring and media creation/edition software. The need to do this is essentially, to provide a cross UI between all major media-related software. This way we can make all media-related software in the open source world to have the same and effective User Interface, so the user can work more tightly between applications and we can collaborate to each other. The project is just starting, and we want to put all of our effort to design, develop and migrate to a efficient, fast and beautiful User Interface. Please, think on it. As a starting point https://launchpad.net/linux+design+studio<http://www.launchpad.com/linux+design+studio> Hoping to make the big jump in the community. Best regards. dael99 (Brian Vidal) -- Brian Vidal

GSoC 2009 - Time to wrap things up
by Joshua A. Andler 17 Aug '09

17 Aug '09

Hey GSoC students and mentors, I just wanted to give a reminder of the schedule for GSoC. Students, today is the pencils down date. Please make sure that your mentor has access to your work today. You do have one week (until the 24th) to do any tweaks or code cleanup, but you should effectively be done at this point. Please be respectful of your mentors and don't force them into doing a last second evaluation. Also, if you are planning to use the additional time for more work, please do communicate that with your mentor. Mentors, evaluations can begin starting today and are due on August 24th. No need to rush as I'm sure we'll see some changes trickling in still. That's all for now. Cheers, Josh CCing dev list so everyone know where we're at.

SPEventContext stops receiving button1 press/release events
by Arcadie M. Cracan 17 Aug '09

17 Aug '09

Hello, I don't really understand what I am doing wrong. I have a button on the toolbar of the connector tool (InkAction) that, when gets pressed, basically creates a new knot that follows the mouse pointer. At this point (after the button is pressed) SPEventContext (for the connector tool) stops receiving any button1 press/release events. Other buttons press/release, pointer motion events are received. I don't even have a clue for where to start debugging, please help. Thank you. Following are some code exerpts: from toolbox.cpp: =========== ... g_signal_connect_after( G_OBJECT(inky), "activate", G_CALLBACK(sp_connector_new_connection_point), holder ); ... static void sp_connector_new_connection_point(GtkWidget *widget, GObject *tbl) { SPDesktop *desktop = (SPDesktop *) g_object_get_data( tbl, "desktop" ); SPConnectorContext* cc = SP_CONNECTOR_CONTEXT(desktop->event_context); if (cc->mode == SP_CONNECTOR_CONTEXT_EDITING_MODE) cc_create_connection_point(cc); std::cout<<"Done new connection point."<<std::endl; } ... from connector-context.cpp ================== ... void cc_create_connection_point(SPConnectorContext* cc) { if (cc->active_shape && cc->state == SP_CONNECTOR_CONTEXT_IDLE) { if (cc->selected_handle) { cc_deselect_handle( cc->selected_handle ); } SPKnot *knot = sp_knot_new(cc->desktop, 0); cc_select_handle( knot ); cc->selected_handle = knot; cc->state = SP_CONNECTOR_CONTEXT_NEWCONNPOINT; } } ... Regards, Arcadie Cracan
