Suggestion: Calligraphic presets - save and edit
by microUgly 26 May '08

26 May '08

Sorry if I'm raising a suggestion that has already be discussed. I've just tried out the calligraphic preset option in the May 22 Win32 snapshot. When you select a preset and make a change, instead of the preset selection jumping to "No preset" can the preset selection remain except with a "*" beside the name (i.e. Marker*)? This will make it easier to identify which preset you had been using before making a change. When you choose to save the changes, populate the "Profile name" (should that be changed to "preset name"?) with the select preset name so you can easily save over it. With these changes you could change "No preset" to "Default" and allow users to easily define their own default. In my work I'll probably create a few presets combinations such as "Slow thin" and "Fast fat" etc. But every drawing will be slightly different, and in some cases the same part of the same drawing might require tweaking of the settings. So being able to quickly tweak and save my presets would be an useful feature. -- View this message in context: http://www.nabble.com/Suggestion%3A-Calligraphic-presets---save-and-edit-tp… Sent from the Inkscape - Dev mailing list archive at Nabble.com.

crash when using ellipse for pattern on path LPE
by bulia byak 26 May '08

26 May '08

terminate called after throwing an instance of 'Geom::RangeError' what(): lib2geom exception: there is no ellipse that satisfies the given constraints: ray(X) == 0 && ray(Y) == 0 but initialPoint != finalPoint (2geom/elliptical-arc.cpp:468) This didn't work before, but at least it didn't crash :) -- bulia byak Inkscape.

on palettes
by Alexandre Prokoudine 26 May '08

Hi, Apparently Fedora has a new design style: https://fedorahosted.org/echo-icon-theme/wiki/Guidelines Should we, Inkscape guys and gals, include the echo-palette.gpl to the bundle (like we do with Ubuntu), or should we, CREATE guys, bundle it with CREATE resources package? :) Alexandre

SVG Fonts: current status
by Felipe Sanches 26 May '08

26 May '08

------ If you just wanted to see some SVGFonts rendering, stop reading, this is not ready yet... ------ I have been working on SVG Fonts and I have recently created a coupe of files (src/display/nr-svgfonts.{cpp,h}) to deal with cairo userfont feature (rendering). It is still incomplete code, of course. I am sending a patch attached to this email. It has several issues: * Still doesnt render at all :-P (but the cairo userfont callbacks seem to be called properly, so it is a matter of time&pacience to get it working) * The userfont callbacks are called only once for each glyph. It means cairo is caching my glyphs, which will be a problem when the user modifies them. * It deals with only one <font> declaration (should be extended to various svgfonts in a single document). * Currently I have been trying to test this code by calling cairo_set_font_face (ct, nr_svgfonts_get_user_font_face()); cairo_show_text (ct, "A!@A"); But I do not have a proper place to put this call. I have tried to call if from within nr-arena-render-glyphs.cpp, but it is probably wrong. * Our SVG fonts are not registered to the fontlister nor managed by pango yet. * We still depend on pango integration so that we can fed pango with our cairo_font_face_t* created by nr_svgfonts_get_user_font_face(). This would be integrated with the current pango code that exists in inkscape. * I also admit that I need to study a bit more about how inkscape handles units and how these are fed to cairo. Some units&coordinates in this patch are arbirary guesses. Also, this patch depends on linking inkscape to cairo development branch (git master) which has support for userfonts. That's one of the reasons why this has not been commited to svn yet. I don't want to branch, but I will do it if there's no other option. I would rather prefer to have --enable-svgfonts option in ./configure Can anybody help me with that? I have never done this kind of thing. cheers, Juca

Serious regression!
by Diederik van Lierop 26 May '08

26 May '08

Hi all, In current SVN I cannot do anything useful with paths! For example, when I draw a simple line then I notice things like this in the XML editor d = m 140,6.21105e+184 308.6,0 Similar things happen when trying to translate a node or a line. Things worked perfectly until maybe a few days ago. I just tested a previous build of may 15th, but that one works just fine. Is anyone else seeing this? Does this ring a bell for someone? BTW, I tested this at work on a XP machine. Diederik

Calligraphy Tool
by Fela Winkelmolen 25 May '08

25 May '08

Hi! I'm currently implementing a calligraphy tool, much like the one present in Inkscape, for Karbon as a Google Summer of Code project. I've heard rumors that there is a plan to rewrite the calligraphy tool of Inkscape, but I couldn't find anything in the ml archives about it. If I understood it correctly the main reason is to make it possible to edit the path in an easier way--actually making it possible to edit the path drawn instead of the final shape created by the tool. I've heard the idea seem to be to use pattern on path, but that doesn't seem to me to be very easy to get right, particularly becase in this case the "pattern" depends on the path. I would like to hear more about this, is there any concrete idea about how it would be implemented, or is it only a vague idea? Also, if you have any other kind of advice, please share! =) Thanks, - fela

memory usage
by Florian Lohoff 25 May '08

25 May '08

Hi, i am thinking of digging a bit into inkscape code concerning the memory usage. As some might know inkscape is used for rendering tiles for OpenStreetmap (Osmarender) or better InformationFreeway. I have seen inkscape regularly consuming up to 12GB (yes - twelve GIGABYTE) of memory to render a tile. Less complex tiles get away with 300-1200MByte of memory which also is a huge amount of memory. This memory issues reduces the number of machines capable of hosting the "tilesat home" client quite drastically (64bit Linux with 16GByte of ram). I have seen that there way a Memory track for the Google SOC 2006 to reduce the inkscapes memory - What has been the outcome to this? My first imagination is that probably the garbage collector does not kick in because of using inkscape in batch mode or somethin. I ran inscape with GC_LEAK set and found the GC running so its not an issue of not reclaimed memory.

<title> and <desc>
by Stephen Silver 25 May '08

25 May '08

I'm currently working on making the title and description fields in the Object Properties dialog work (bug 171024). SPObject already had some dummy member functions to get and set titles and descriptions, so I've turned these into working functions. But I see that there are also dummy non-member functions that are supposed to do the same thing. I could easily implement these using the member functions, but it seems like pointless clutter to have both member functions and non-member functions doing the same thing, so I'm tempted just to delete them (they are not used anywhere, except in the macros SP_OBJECT_DESCRIPTION and SP_OBJECT_TITLE, which are themselves unused). Is there any reason to keep the non-member functions? -- Stephen Silver

Bezier crash in SVN
by Josh Andler 24 May '08

24 May '08

On two different linux boxes, if I compile from current svn, any use of the pen/bezier tool crashes inkscape. Unfortunately, it seems like there may be stack corruption as the backtraces don't look very useful. Both boxes in question are running Ubuntu 8.04. Would someone else on linux confirm if they're having this problem? (yes, I have two separate boxes exhibiting it, but they're the same distro). Thanks, Josh
