Eyedropper for gradients
by Adam Pearson 27 Jul '04

27 Jul '04

Hi all Congratulations to all on the latest version - it's great! Is there a way that I can use the eyedropper for editing/creating gradients? A lot of what I do is illustration work and I am now using Inkscape by default. Often I use a photograph for a model for at least part of a drawing, it would be good to pick up two (or more) colours from the photo to create the gradient that I want. Can I do this? I think I could do it the long way round by picking one colour to an object, noting its RGBA number, then doing the other, then using these RGBA numbers .... but is there a more direct way? Regards Adam in Oz

Most of these are inline functions, so any information about them is normally stripped away by the optimizer. (In general the optimizer may rearrange the code in ways that do not correspond to the source code.) > And the backtrace : > (gdb) backtrace > #0 0x080ede58 in std::list<sigc::slot_base, > std::allocator<sigc::slot_base> >::empty() const (this=0x8) at > stl_list.h:628 > #1 0x080edcb6 in sigc::internal::signal_emit1<void, SPObject*, > sigc::nil>::emit(sigc::internal::signal_impl*, SPObject* const&) > (impl=0x0, _A_a1=@...193...) > at signal.h:616 It would seem that sigc++ is dereferencing a NULL pointer. To the best of my knowledge, emitting an unconnected signal (having a NULL impl) should be harmless (sigc++ should check the pointer). This sounds like a sigc++ bug. > and libsigc-2.0 : 2.0.2 Try upgrading to 2.0.3, which is the version I have. -mental

shift 3 and \ does not work
by Aewyn 26 Jul '04

26 Jul '04

I have some problems, these are not bugs, but makes work difficult. 1., I have got trouble with snapping to grids and snapping to guides. I have hungarian keyboard, so on main keyboard there is "+" above "3". When I try to toggle snapping to grid, it zooms instead of snapping. The "\" is on my "Q" key (with Alt Gr), so it is unusable for snapping. (I can use # and | to hide grids, but it's not a solution) ---- 2., The "open file" dialog forgets his size, what is annoying, because it is very little in default. ---- 3., Inkscape does not handle file names with accent, so this file is invisible for inkscape: azénrajzom.svg Thank you very much for help, Aewyn (and please let the right button on mouse to unzoom when the zoom tool is selected, thanks)

Crash on startup
by Florent 24 Jul '04

24 Jul '04

Hi all, I'm trying to compile the latest inkscape CVS and so I have update some libs : glibmm (to 2.4.3) , gtkmm (to 2.4.4) and libsigc++ (to 2.0.2) on my Linux system. There was no problem with "./configure" or "make" but impossible to launch Inkscape :( I've got the message "Inkscape encountered an internal error and will close now." immediatly at the startup. Does anyone have an idea ? FlorentGabriel

Inkscape 0.39
by Ted Gould 20 Jul '04

20 Jul '04

= Inkscape 0.39 = We are pleased to announce the Inkscape 0.39 release. The most important change in this release is the switch to the Pango library for font handling and Unicode support; a lot of work also went into new SVG features, export/import, UI, and usability. Here are the highlights: * Pango: smoother text display, auto kerning, better i18n (automatic font substitution, right-to-left text, bi-directional text), less platform dependence * New SVG features: markers (aka arrowheads), clones (svg:use), pattern tiles, RDF metadata; many SVG compliance bugfixes * New dialogs: Preferences, Find, Metadata * New and improved import/export file formats: PS, EPS, AI, PNG, JPEG, TIFF, BMP, Sketch, Dia, and more * Pure convenience: usable dropper, scale switches, Commands bar, more tool controls (including rounded stars), more import formats, more paper sizes, Revert command, edit inside group, better selection cues, spell checking, window layout configurable, streamlined Fill & Stroke, snapping improvements, better rounded corners in rects, path reversing, persistent rotation crosshair, per-object export hints, and much more * Internals: speedups, more C++ification, garbage collection, SigC++ signals, wider use of new data structures, extensive cleanup * Plus: new documentation, new translations, lots of assorted bugfixes (the infamous "freeze when dragging outside of window" bug on Windows is gone!) The team has placed a great deal of scrutiny into fixing bugs, and while this was not a primary focus as it had been for 0.38.1, we expect this release will be at least as stable as the last. Many thanks go out to all of the users that took the time to write bug reports, you make Inkscape better. For tons more details, see the Release Notes for 0.39: http://www.inkscape.org/cgi-bin/wiki.pl?ReleaseNotes039 Screenshots: http://www.inkscape.org/screenshots/ Download your packages (Linux, Windows, Mac OSX): http://sourceforge.net/project/showfiles.php?group_id=93438

more about two problems with lines and polygons

I apologize for opening a new thread, but I guess I should asked first how to subscribe to this list before sending questions!. I think I subscribed correctly this time. > Sounds like you want to first use the Combine operator (Path>Combine > or Ctrl+k) on several selected objects using the select tool (F1). > Then, using the node editing tool (F2), select a pair of endpoints > that you want to join and use the third and fourth buttons from the > Tool Controls bar (they have a green downward arrow). Yes it worked, but I think I will do for the difficult part most of the time I have about 500-1000 nodes to connect. Is not efficient at all to do by hand. >Ouch. That is difficult, but here are some ideas: > > * Work out what all the paths you want to join have in common (e.g. > they all have a "stroke:#00FFFF" string in the style attribute). > * Sort the objects so all the <path>s to combine are in one spot. > * If the endpoints of two separate parts of the path are at the same > co-ordinate, you may be able to join them.

I have to do this for 500 objects, this wouldn't be so bad if duplicating objects woudln't give me an offset (when I duplicare and objec it always have a different position than the original). But your answer gave me a very interesting challenge, (that I havent seen in any other graphics editor). Is there a posibility to implement a scripting language for this editor?. Has somebody asked for something like that?. I mean, instead of doing single operations. Is there any posibility to do complicated boolean operations in one single step, defining the operators and variables (suppose that the selected objects are A and B), and then just running: C=A; D= A U C; R= D - A; print; probably the best way to implement such a scrpting language would be in a lisp style. Anyway, and sorry for the disgression.

HELP WANTED: OSX packager for 0.39
by Bryce Harrington 17 Jul '04

17 Jul '04

Hi all, We have not had Mac OSX packages to provide in the past, but we'd certainly like to! OSX is an important platform for artists, and it would make sense for Inkscape to have a good presence there, as it does on Windows and Linux. Kees and others have verified that it builds and can be run on OSX, so the hardest part is done. The notes are available here: http://inkscape.org/cgi-bin/wiki.pl?CompilingInkscape What we need is someone who can create a package that other OSX users can easily download and install. This probably doesn't require any coding know-how, but does require someone knowledgeable of fink and in compiling under OSX. If you're interested, please go ahead, and when you've got a working package, announce it here, and we'll add it to the Download area. :-) Bryce

need help to compile inkscape 0.39 in macosx
by Albert 17 Jul '04

17 Jul '04

Hi all I'm trying to compile inkscape-039pre4 in macosx and I'm running into this problem: No package 'gtkmm-2.0' found configure: error: Library requirements (gtk+-2.0 >= 2.0.0 libxml-2.0 >= 2-2.4.24 sigc++-1.2 gtkmm-2.0 ) not met; consider adjusting the PKG_CONFIG_PATH environment variable if your libraries are in a nonstandard prefix so pkg-config can find them. I know I have gtkmm1.2 installed and than I need then to install 2.0, but the question is: inkscape 0.38 did NOT require neither gtkmm1.2 nor 2.0. I thought this would be necessary from 0.40 and onward, not before. When was this changed, or what did I miss? Also, which gtkmm should I install: 2.0-2.2, or 2.4 ? Does anyone know if any of this 2 libs have any problems in macosx ? Thank you for any help. Albert

two problems with lines and polygons.
by Roberto Ortega 16 Jul '04

16 Jul '04

I work with maps in a regular basis and I have two problems. Dealing with maps always needs some tools to prepare the base of the projection, contour lines, state borders, and then to convert to the appropiate design tool. These are the two problems: 1) When I convert to SVG the map looks ready to work, but all the lines are discontinuos even that they look continuos in appearence. In other words, they are segment of lines overlapping to each other. Therefore when I select a contour line or a state border, I can not work with it unless I join all the line segments. I tried all the possible options to join to separate lines into one, but I didn't succeded. It seems that the node tool is only for the same object. Can you give me a hint how to tackle this problem?. I also want to fix the problem since the begining, I want to write a small program to fix the SVG file and convert it directly to single lines. I need your advice to do it. 2) Many times I have a closed polygon, therefore I can fill with color, put patterns, etc. (for examlpe a State line). And sometimes I have an open line that is not closed but the two end-nodes touch closed polygons (in this case the border state). I want to convert the open line to a closed polygon using boolean operators. The problem is that I have to preserve both polygons. At the end I need two closed polygons. ( I guess my boolean arithmetic is not good enough). I need some hints. Thank you... Roberto
