Hi, Compiling Inkscape r12251 (http://bazaar.launchpad.net/~inkscape.dev/inkscape/trunk/revision/12251) on Windows XP returns the following error message. Alex, could you please take a look? ---- Make error line 301: problem compiling: src/registrytool.cpp: In member function 'bool RegistryTool::setStringValue(cons t Glib::ustring&, const Glib::ustring&, const Glib::ustring&)': src/registrytool.cpp:55:19: error: variable 'Glib::ustring keyName' has initializer but incomplete type src/registrytool.cpp:71:5: error: 'gunichar2' was not declared in this scope src/registrytool.cpp:71:16: error: 'keyw' was not declared in this scope src/registrytool.cpp:71:70: error: 'g_utf8_to_utf16' was not declared in this scope src/registrytool.cpp:72:16: error: 'valuenamew' was not declared in this scope src/registrytool.cpp:72:54: error: invalid use of incomplete type 'const struct Glib::ustring' src/registrytool.h:25:11: error: forward declaration of 'const struct Glib::ustring' src/registrytool.cpp:73:16: error: 'valuew' was not declared in this scope src/registrytool.cpp:73:50: error: invalid use of incomplete type 'const struct Glib::ustring' src/registrytool.h:25:11: error: forward declaration of 'const struct Glib::ustring' src/registrytool.cpp:86:56: error: invalid use of incomplete type 'const struct Glib::ustring' src/registrytool.h:25:11: error: forward declaration of 'const struct Glib::ustring' src/registrytool.cpp:88:77: error: invalid use of incomplete type 'const struct Glib::ustring' src/registrytool.h:25:11: error: forward declaration of 'const struct Glib::ustring' src/registrytool.cpp:98:16: error: 'g_free' was not declared in this scope ....

Oh I see it deleted my attachment... But when my patch is uncompressed it doesn't like it either, as it's too big... Here's a link then: http://dl.dropbox.com/u/37427492/virtual_pads.patch Markus

C++ification of the SPObject tree
by Markus Engel 28 Mar '13

28 Mar '13

Hi, I'm new here ;) . As I really like Inkscape I thought I'd help out programming. In order to gain some insight I started with a janitorial task, I put the virtual function calls in the SPObject tree into C++ classes. I found the procedure of porting the tree to C++ described in the wiki: http://wiki.inkscape.org/wiki/index.php/CPlusPlus This works quite well. In the attached patch you can find those "virtual pads". At the moment I'm turning all the other functions into real member functions and I'm playing around with a new factory that is independent of glib. Tell me what you think about it. Markus

Something special about Cairo glyph draws?
by mathog 27 Mar '13

27 Mar '13

There is something strange going on related to glyph draws through Cairo which I have not been able to figure out. Hopefully fresh eyes will spot the problem. In drawing-text.cpp this is the code that outputs the series of glyphs which put text on the screen, slightly modified to put a line over the glyphs (my changes all start at the first character on the line and end with "//"): Geom::Affine aff; // bool aff_set = false; // for (ChildrenList::iterator i = _children.begin(); i != _children.end(); ++i) { if(!aff_set){ // aff = g->_ctm; // aff_set=true; // } // DrawingGlyphs *g = dynamic_cast<DrawingGlyphs *>(&*i); if (!g) throw InvalidItemException(); Inkscape::DrawingContext::Save save(ct); if (g->_ctm.isSingular()) continue; ct.transform(g->_ctm); ct.path(*g->_font->PathVector(g->_glyph)); } // draw a rectangle over all of the glyphs, tsp_width_adj has the correct value if(aff_set){ // ct.transform(aff); // ct.rectangle( Geom::Rect(Geom::Point(0.0,0.0),Geom::Point(tsp_width_adj, 0.1)) ); // } // The strange thing is that the rectangle draw results in an XOR against the underlying glyphs. (Overlaps are not filled.) The reason this is bizarre is that when the code is modified so that the glyphs overlap each other (easy to do, just change the "g->_ctm" in ct.transform() to "aff") the glyphs do not XOR against each other. Use a string like "XO" to see this. Instead they just draw over each other, as one would expect for all of these draws. I thought the XOR might have something to do with the ct.rectangle() call, so made an alternate version where the rectangle is first converted to a (closed) PathVector "rectpath" and then this is done: ct.transform(aff); // ct.path(rectpath); // Unfortunately, this also had the XOR effect. I am puzzled. Where is the XOR effect coming from? More to the point, what is special about the glyph paths so that if they overlap there is no XOR, but a glyph and a rectangle or another path do XOR? By placing a DEBUG print statement at the top of _renderItem() one can see that this method is called twice for every string (actually <tspan>) in the document which is updated/changed. I suppose the XOR effect might have something to do with that, but it does not really make sense either, since the glyphs are drawn as many times as the overlapping line.

Crediting Tango icons for Inkscape
by Peter Uithoven 27 Mar '13

27 Mar '13

Hi Inkscape Developers and Designers, I'm involved with the application VisiCut, an opensource and more userfriendly application to talk to Lasercutters. http://visicut.org/ One of the things I'd like to do is introduce better icons. I really like you guys work on the Tango icons for Inkscape. So I'd like to properly credit the authors / designers. Could you guys help me out on how to do that? At the moment I would use: Tango Icon Library 0.8.90 (tango) link: http://tango.freedesktop.org/Tango_Icon_Library license: Public Domain Inkscape (inkscape) link: http://www.inkscape.org/ license: GPLv2 I found the icons in the Open Icon Library<http://openiconlibrary.sourceforge.net/>, but it's a bit unclear which icon is from which source. Great work on Inkscape btw, I'm involved with Fablab Amersfoort<http://www.fablabamersfoort.nl/nl> and it's one of the tools we advocate. Thanks in advance, Best regards, Peter Uithoven

Gtk+ backend target
by Alex Valavanis 26 Mar '13

26 Mar '13

Hi All, Why do we explicitly check for the Gtk+ backend target in configure.ac? The resulting $gtk_backend_target variable isn't used anywhere except for deciding whether to link the -lX11 library or not. In fact, this seems unnecessary too, because gtk+ reports whether it needs -lX11 via pkg-config so we should pick up the dependency automatically. Our method of checking the backend target isn't supported by gtk+ 3 in any case, so can we get rid of the test? AV

Suggestion of Recolor-Artwork Tool.
by Arshdeep Singh 26 Mar '13

26 Mar '13

Dear devs, Need some advice on my suggestion of recolor-artwork tool based on Illustrator's similar tool. *Advantages of the tool: *1.) Lets you manage interdependence of colors. For example, you select a circle and a rectangle respectively colored RED and ORANGE. For some reason you want to port the whole 'tone' to something cooler. You select the two objects on the canvas, lock their nodes on the color wheel and rotate the rays of the objects to the blue wedge area of the wheel. Now with a single step you can manage the color tones and relationship of different objects. This should prove very beneficial for designers/artists. *My Blueprint: *[image: Inline image 1] *Steps:* 1.) Get the colorwheel drawn using the source files "gimpcolorwheel.c" as reference. 2.) Get the GUI for selected objects (based on the XML Tree) [First prototype will only handles solid colors] 3.) Functions for locking the nodes, rotation, dragging etc. Any inputs / advice / suggestions are heartily welcome. -- demicoder

documentation on the Perl component?
by Bric 26 Mar '13

I can't find any documentation on the Perl component. When I compiled 0.48.4 I used --with-perl, which looked promising. How do I use this component? thanks

units (revisited)
by Bric 25 Mar '13

25 Mar '13

Hi Not sure if this belongs to the "devel" mailing list (maybe tangentially, if it leads to enhancements?) I know this has been addressed before, but I couldn't find the final resolution to all the questions (here's a related post that doesn't seem to clinch it: http://www.inkscapeforum.com/viewtopic.php?f=5&t=10646) I have the same problem: via the command line I'm getting one type of value, but in the SVG document a different value is listed. COMMAND LINE: inkscape -f doc.svg --query-x --query-id=rect4487-1-7 139.43438 inkscape -f doc.svg --query-y --query-id=rect4487-1-7 128.13251 WITHIN THE SVG DOCUMENT: <rect id="rect4487-1-7" ry="0.53296167" height="1.0654094" width="10.142718" y="72.914459" x="79.345848" style="fill:currentColor" /> Also, within the svg doc, the dimensions are: width="315" height="206" And thus the above can't seem to account for the discrepancy, by means of origin position adjustment (width - x, height - y) So far, it looks like different units are used. thanks
