[PATCH] Fixing strings when exporting to JavaFX files
by Silveira Neto 13 Nov '08

13 Nov '08

Some exported codes couldn't compile in JavaFX due to spaces and minus signs on id labels. The sanatize function creates a new string with them replaced by underscores, solving the problem. Diff agains revision 20175.

Inkscape book on Floss Manuals
by Joshua Facemyer 13 Nov '08

13 Nov '08

A little PR for the Inkscape Docs team: We recently got our Inkscape Manual (the fruit of our Book Sprint) put on Lulu (http://www.lulu.com/content/4617381). You've probably seen the article by the Russian on the inkscape.org which has a link - if not, check it out! The published book, while being a reasonably finished work of good quality, is not comprehensive. We would like it to be more so. Here are some things that will help us to continue with this work: 1. Sales of the current version (somewhat limited 1st EDITION!!!!) on Lulu will help us afford a future Booksprint. 2. Contributions to the manual on our Floss Manuals workspace are greatly needed. Of course, as this needs some coordination, it's best to start on the inkscape-docs list (signup at lists.sourceforge.net) to find out where to begin. 3. Magical powers to generate whatever good thing we want without much effort. If you can help with any of these things, that would be GREAT! In particular, getting word out and posting the link to the Lulu store would be of great benefit. JF

compiler errors on windows
by pete mcquain 12 Nov '08

12 Nov '08

Hello, I'm trying to get my build environment up and running under Vista and am running into a compiler error: src/display/nr-svgfonts.h:37: error: 'cairo_text_cluster_flags_t' has not been declared I'm using the command-line tools and I'm building against the most recent source from SVN. I got the most recent devlibs zip and mingw from http://inkscape.modevia.com/win32libs/. Does the devlibs archive have the correct cairo includes? Thanks! pete mcquain

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

Rendering test results now with totals
by Jasper van de Gronde 11 Nov '08

11 Nov '08

The rendering test results page now shows totals for each displayed run (in addition to color coding the results and linking bug related tests to their launchpad bugs): http://home.hccnet.nl/th.v.d.gronde/inkscape/ResultViewer.html This makes it a little easier to see the results at a glance. (Currently still 64 out of 164 tests fail...)

Doxygen conventions
by Krzysztof Kosiński 11 Nov '08

11 Nov '08

Somebody undid my changes to the files in src/bind/, so I'd like to discuss the doxygen convention used for files here. I already said about this in another thread but it wasn't too visible. I think the proper template for a source file goes like this: /** @file * @brief Brief description of what this file contains */ /* Authors: * Some Author <author@...2068...> * * Copyright (C) 2008 Authors * Released under GNU GPL, read the file 'COPYING' for more information */ #ifndef INCLUDE_GUARD #define INCLUDE_GUARD // ... code ... #endif /* Local Variables: mode:c++ c-file-style:"stroustrup" c-file-offsets:((innamespace . 0)(inline-open . 0)(case-label . +)) indent-tabs-mode:nil fill-column:99 End: */ // vim: filetype=cpp:expandtab:shiftwidth=4:tabstop=8:softtabstop=4:encoding=utf-8:textwidth=99 : Important points: 1. @file on the first line - it has to be present to document a file, and no point in moving it to the second line since it's boilerplate. When @file isn't present, usually the Inkscape namespace is documented instead of the file. 2. Copyright information not included in the doxygen comment - it's not very useful there 3. Include guard after file description and copyright information - this is the current convention; it makes the placement consistent between headers and .cpp files 4. Completely nothing after vim modeline - otherwise it doesn't work, at least in gedit It seems the main issue of contention was 2, but I don't know what are the arguments for leaving the copyright info in the documentation. I don't think there are any copyright issues with the doxygen comments because the documentation is meant for internal use and not widely useful outside of the Inkscape developer community. Even if that's the case we could put a (C) notice on the main page so that other pages are not cluttered with duplicated information.

A lot random crashes in recent SVN version
by Vladimir Savic 10 Nov '08

10 Nov '08

Note: Subject of this mail is not a complaint. I just wanted to bring this to focus. Here's the backtrace of one that looks like snapping related. I can repeat these crashes, but it happens mostly while dragging objects around and panning using middle mouse button. BTW, Looks like one needs to press middle mouse button absolutely still for some time in order to pan around. Also doesn't happen all the time, but when it does, that's the workaround. At least here. Regards, Vlada inkscape: /usr/include/boost/optional/optional.hpp:578: typename boost::optional_detail::optional_base<T>::reference_type boost::optional<T>::get() [with T = NR::Rect]: Assertion `this->is_initialized()' failed.

LPE on groups with shapes
by unknown＠example.com 09 Nov '08

09 Nov '08

Hi all, Did group LPE ever work on shapes in a group? I.e. I have a group with stars in it, then apply bendpath on the group. The SVG is correct, but Inkscape displays the stars unbent. It's because of this here: static void sp_star_update (SPObject *object, SPCtx *ctx, guint flags) { if (flags & (SP_OBJECT_MODIFIED_FLAG | SP_OBJECT_STYLE_MODIFIED_FLAG | SP_OBJECT_VIEWPORT_MODIFIED_FLAG)) { sp_shape_set_shape ((SPShape *) object); } if (((SPObjectClass *) parent_class)->update) ((SPObjectClass *) parent_class)->update (object, ctx, flags); } during an 'update', sp_shape_set_shape is called again, which resets the shape's curve of the group-lpe calculation... (if i comment that line out, group lpe works fine...) Can someone help me on this one? What's the solution? Cheers, Johan

2geom update: new Rect and OptRect
by unknown＠example.com 08 Nov '08

08 Nov '08

Hi all, I just updated 2geom in our trunk. It contains the 'new' Rect and OptRect (and Interval and OptInterval). Geom::Rect can no longer be empty. It *always* contains a rectangle. Geom::OptRect contains a rect or nothing (which means an empty rect). The same holds for Geom::Interval and Geom::OptInterval. For example, boundingbox functions return an OptRect. You have to check whether it is empty or not, before you use the values in the Rect. If you didn't and turns out the bbox is empty, Inkscape will crash :-) Note that Rect's no longer have the method 'isEmpty'. Rect's do have the 'hasZeroArea' method. If this is true, the Rect contains a single point, like a (0,0)-(0,0) rectangle. It's not empty, it contains one point (0,0). (OptRect and OptInterval have the same usage as boost::optional<Rect>) I made Inkscape compile with this update, and tried to fix cases where there was not an explicit empty check. I may have introduced/uncovered bugs, sorry for that. Let us know about what you've found. Cheers, Johan
