Persistent Undo update
by Daniel Genrich 19 Oct '07

19 Oct '07

Hello everybody, I just took some time to make the "persistent undo" patch (http://people.csail.mit.edu/sarasu/history/) working with todays SVN and to make it also compile with gcc 4.1.2. It's patch #1816710 in the patch tracker. When applying the patch - don't forget to "./configure" again because of new files. I hope this makes review/work/testing on the "persistent undo" patch easier :) Thanks! Genscher

margins for textframes
by David Christian Berg 19 Oct '07

19 Oct '07

Hey Inkscapers! Just want to draw some attention towards RFE [ 1597125 ] Space between text and frame border again. I'm not a coder, but since all we need is a interface it should be achievable... and I think it would really improve Inkscape for simple task quite a lot. I know, it's not fancy, but well, yeah, useful... Take a look at the attached SVG... it explains what I already tried to state in the RFE report. Take care! David

Effect that modifies the document properties?
by John Bintz 19 Oct '07

19 Oct '07

Hello. I'm trying to write an Effect extension that will allow the creation of cover templates for perfect bound books, which involves changing the document properties and adding guides lines to the current document. I have a Ruby script and an .inx file set up correctly, and when I examine the XML output from the script, the SVG that is returned is correct. When this file is written back to stdout at the end of the script, no changes occur within Inkscape. Can Effects modify the document properties and, if they can't, would it be a good idea to add a new type of extension that could? Thanks, John

Strange behaviour of text flowed into a combined shape
by David Christian Berg 18 Oct '07

18 Oct '07

Hey Inkscapers, After my last mail about text, I played around a little more again and stumbled over a very strange behaviour. I have to boxes which are combined and text is flowed into them. I placed them one below the other... I imagined the text would continue in the second box... but unless its really close, it doesn't. Open the attached fly, mark the below box with the node-selection tool by selecting all nodes and move the box down with the arrow keys... the text will disappear from it. I guess I should file a bug, shouldn't I? But maybe it would be good to know, what causes the problem... Cheers! David

Re: [Inkscape-devel] contribute to graphics research!

Hi bulia, Joshua, and all: I apologize for my delay in replying to your messages. I just got back from the UIST conference, where I met many UI researchers -- and fellow Inkscape users. Thanks for your enthusiasm about the undo-saving feature! We would like to release the code for this for all the reasons you mentioned: to comply with the GPL, to get users across platforms, and ultimately to contribute to the Inkscape project. [We'd also welcome help identifying and fixing bugs. :)] What is the best way to do this? As the number of files touched is small, perhaps the fastest is to post these on our website, then work on adding the changes to the SVN trunk. Thanks for your invitation to do so.

Canvas Rotate - Alternative?
by microUgly 18 Oct '07

18 Oct '07

Is the canvas rotate idea currently being implemented? I found the thread from April which had a lot of great ideas but I didn't know if anyone was working on it of if it's on the list of things to do. I know what was discussed sounded like really clever stuff and I can only guess how difficult the feature may have been to implement. So I was wondering if a simple alternative could be adopted instead - the alternative being that instead of rotating the Inkscape viewport we rotate a SVG layer. I could just rotate a group, but I think rotating a layer instead is bit easier since you won't have to jump in and out of the group everytime you need to adjust the rotation. But there isn't a control for rotating layers currently. The control could be displayed on the layer palette and behave much the same as the Opacity slider. The only catch is, for it to be most useful, it would be best if the centre of rotation could be quickly and easily set where you wanted. Bad idea? -- View this message in context: http://www.nabble.com/Canvas-Rotate---Alternative--tf4645455.html#a13269725 Sent from the Inkscape - Dev mailing list archive at Nabble.com.

Problem compiling with gcc 4.2.2 and libsigc++2.0 v2.1.1
by Martin Schmidt 18 Oct '07

18 Oct '07

Hi, I have a serious problem getting to inkscape-svn to compile with gcc 4.2.2 and libsigc++2.0 v2.1.1. It used to work with gcc 4.2.1 and v2.0.18. Also, I have been trying to get the beautiful PDF Import to work (and actually got it to work with the above mentioned software). There was a problem with poppler not installing the Cairo headers by default. You might or might not be aware of the fact that this has a reason: the poppler guys do not guarantee a stable API for those functions. I have talked to one of them on IRC and he was disappointed because of the lack of communication between the SOC students and the poppler devs... I just mean to make you aware of the fact that there might be incompatibilities lying ahead, which I would deeply regret, because I have seen the PDF import work, and am totally blown away by it. In my eyes this is a killer app. So keep up the great work, Martin LOG: depbase=`echo select-context.o | sed 's|[^/]*$|.deps/&|;s|\.o$||'`;\ g++ -DHAVE_CONFIG_H -I. -I.. -I../../inkscape/src -I/usr/lib/perl5/5.8.8/i686-linux-thread-multi/CORE -I/usr/include/freetype2 -I/usr/include/libgnomeprint-2.2 -I/usr/include/libart-2.0 -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/include/libxml2 -I/usr/include/pango-1.0 -I/usr/include/libgnomeprintui-2.2 -I/usr/include/libgnomecanvas-2.0 -I/usr/include/freetype2 -I/usr/include/gail-1.0 -I/usr/include/gtk-2.0 -I/usr/include/atk-1.0 -I/usr/lib/gtk-2.0/include -I/usr/include/cairo -I/usr/include/libpng12 -DRELAYTOOL_CRYPTO='static const int libcrypto_is_present = 1; static int __attribute__((unused)) libcrypto_symbol_is_present(char *m) { return 1; }' -DRELAYTOOL_SSL='static const int libssl_is_present = 1; static int __attribute__((unused)) libssl_symbol_is_present(char *m) { return 1; }' -DHAVE_SSL -I/usr/include/freetype2 -I/usr/include/gtk-unix-print-2.0 -I/usr/include/gtk-2.0 -I/usr/include/atk-1.0 -I/usr/include/cairo -I/usr/lib/gtk-2.0/include -I/usr/include/pango-1.0 -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/include/freetype2 -I/usr/include/libpng12 -I/usr/include/poppler -I/usr/include/poppler/glib -I/usr/include/poppler -I/usr/include/gtk-2.0 -I/usr/lib/gtk-2.0/include -I/usr/include/cairo -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/include/pango-1.0 -I/usr/include/freetype2 -I/usr/include/libpng12 -DPOTRACE=\"potrace\" -pthread -I/usr/include/gdkmm-2.4 -I/usr/lib/gdkmm-2.4/include -I/usr/include/glibmm-2.4 -I/usr/lib/glibmm-2.4/include -I/usr/include/pangomm-1.4 -I/usr/include/gtk-2.0 -I/usr/lib/gtk-2.0/include -I/usr/include/cairomm-1.0 -I/usr/include/sigc++-2.0 -I/usr/lib/sigc++-2.0/include -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/include/pango-1.0 -I/usr/include/cairo -I/usr/include/freetype2 -I/usr/include/libpng12 -I/usr/include/gtkmm-2.4 -I/usr/lib/gtkmm-2.4/include -I/usr/include/atkmm-1.6 -I/usr/include/atk-1.0 -I/usr/include/libxml2 -I/usr/include/gtkspell-2.0 -I../../inkscape/cxxtest -Wall -Wformat-security -W -Wpointer-arith -Wcast-align -Wsign-compare -Woverloaded-virtual -Wswitch -D_FORTIFY_SOURCE=2 -Wno-unused-parameter -march=i686 -mtune=generic -O2 -pipe -MT select-context.o -MD -MP -MF $depbase.Tpo -c -o select-context.o ../../inkscape/src/select-context.cpp &&\ mv -f $depbase.Tpo $depbase.Po In file included from ../../inkscape/src/select-context.cpp:26: ../../inkscape/src/pixmaps/cursor-select-m.xpm:38: warning: deprecated conversion from string constant to 'char*' [...] In file included from ../../inkscape/src/select-context.cpp:28: ../../inkscape/src/pixmaps/handles.xpm:19: warning: deprecated conversion from string constant to 'char*' [...] In file included from ../../inkscape/src/select-context.cpp:40: ../../inkscape/src/seltrans.h:153: error: 'SigC' has not been declared ../../inkscape/src/seltrans.h:153: error: ISO C++ forbids declaration of 'Connection' with no type ../../inkscape/src/seltrans.h:153: error: expected ';' before '_sel_changed_connection' ../../inkscape/src/seltrans.h:154: error: 'SigC' has not been declared ../../inkscape/src/seltrans.h:154: error: ISO C++ forbids declaration of 'Connection' with no type ../../inkscape/src/seltrans.h:154: error: expected ';' before '_sel_modified_connection' make[2]: *** [select-context.o] Error 1 make[2]: Leaving directory `/var/abs/local/inkscape-svn/src/inkscape-build/src' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/var/abs/local/inkscape-svn/src/inkscape-build' make: *** [all] Error 2

Which Non-Latin Scripts Do Free Software Fonts Not Cover?
by Dave Crossland 16 Oct '07

16 Oct '07

Hi All, I've just started the Masters degree in Typeface Design at the University of Reading (for which Gentium was a submitted project) and we're expected to do a non-latin script complement to our font, and I'd thought I'd ask around if anyone here has any opinions about the following: Are there non-latin scripts that free software fonts do not cover at all at the moment? Which non-latin script communities are adopting free software and would benefit from more fonts? Does Inkscape have problems with setting any scripts in particular? :-) -- Regards, Dave

Inkscape less strict than Batik
by Colin Marquardt 16 Oct '07

16 Oct '07

Hi, maybe the following post is of some interest - it talks about replacing Inkscape with Batik as the SVG renderer for OpenStreetMap, and the fact that Batik is more strict than Inkscape in some regards (which should be fixed in Inkscape AIUI). The "issues" mentioned there are memory usage (since OSM got some very detailed maps with lots of elements due to the TIGER data import) which makes Inkscape die with an out-of-memory message (sometimes with destroying the preferences.xml file). It seems the memory usage cannot be helped in the short term (I talked to mental on IRC about that some weeks ago), but I wanted to report the Batik comparison. <http://thread.gmane.org/gmane.comp.gis.openstreetmap.tilesathome/417/focus=…> Cheers Colin
