Just letting the list know: I couldn't have gotten through last week had it not been for PDF import. I want to sincerely thank everyone who contributed in making it this easy to import and work with PDF assets. You are my heros. Andy

This may be a good idea for later, but for now I was interested in "the right"(TM) behavior. What Inkscape used to be doing. :) Johan

Crash in 2geom ellipse parsing
by Jon A. Cruz 30 Jun '08

30 Jun '08

We've gotten bug #243232 that is due to an assertion in 2geom being triggered. terminate called after throwing an instance of 'Geom::RangeError' what(): lib2geom exception: there is no ellipse that satisfies the given constraints (2geom/elliptical-arc.cpp:616) https://bugs.launchpad.net/inkscape/+bug/243232 Can someone familiar with that area take a look? Thanks.

path parsing - nartbpath optimization?
by unknown＠example.com 30 Jun '08

30 Jun '08

Hi all, When parsing "M 0,0 1,0 1,1 0,1 0,0 z", the old nartbpath optimizes it and stores it like: "M 0,0 1,0 1,1 0,1 z". The 2geom path parser does not. So when writing the path back to svg, nartbpath and 2geom don't match up. What to do? Should 2geom optimize the path as well? Or should the svg writer optimize it? Or keep it the way the input was? Thanks for thoughts, Johan

SVGFonts: lot's of questions
by Felipe Sanches 28 Jun '08

28 Jun '08

1. "all text is output to libnr using livarot types, not using cairo" Can you explain that in more detail? I'd like to know: * what livarot types are. * how does livarot distinguish from cairo * does that mean we need to replace livarot? How to proceed? 2. "Getting text layout to use Cairo for output rather than libnr." Can you show me where does that output reside in the code? 3. [09:51:42] <^-> [JucaBlues] so, I guess, we should have in the API a way to provide pango with the metrics specified on svgfonts xml attributes [09:52:03] <^-> [JucaBlues] i mean kerning and stuff like that [09:52:15] <cyreve> yeah which, now I think of it, is exactly what gail is looking at "Finding a way to get the user font through Pango. One (ugly) possibility which comes to mind is to pretend to be sans-serif while going through Pango and then do a fudge afterwards. Gail asked to be a part of this discussion and she's more knowledgable than I am about cleaner approaches which could be taken here, so I've CCed her" I'm still feeling completely lost Juca

In any case, bad data should be handled gracefully, not with a killer assertion. The general rule is to be forgiving on input, strict on output. bob -----Original Message----- >From: Marco <mrcekets@...400...> >Sent: Jun 26, 2008 11:12 AM >To: Marco <mrcekets@...400...>, "Jon A.

more on extensions
by Alexandre Prokoudine 27 Jun '08

27 Jun '08

Hi, A recently added "3D polyhedron" extension is actually more useful than it seems at first site, because it can load arbitrary OBJ files which are basically 3D model objects. Nifty, eh? ;-) What is not so cool is that users are supposed to provide full path to an OBJ file in a text input box. Is it actually possible to hook an Open File dialog to extensions? Alexandre

Support for other than English on OS X
by Jon A. Cruz 27 Jun '08

27 Jun '08

Hi, I finally got time to test a few things about Inkscape.app building on OS X to enable languages other than English. The secret turns out that the Resources folder inside just needs an empty folder with the name of the local and ".lproj" added. For example, to add Spanish it just needs "Spanish.lproj" to be added as an empty directory. And adding an empty "sv.jproj" folder enables Swedish (as "Svenska" in the OS X International control panel). I've attached a simple hack to osx-app.sh for testing. If anyone who's successfully built an Inkscape.app for OSX could test this, that would be a big help. thanks. It's on bug 242105 https://bugs.launchpad.net/inkscape/+bug/242105

OSX native compile error
by Matt Peterson 27 Jun '08

27 Jun '08

Inkscape wants to use Bitstream Vera Sans as the default font, but I don't have that installed on my system so every character becomes ugly rectangles. I cannot figure out how to change the font to something else. I noticed that there is a Resources folder when embedding Inkscape inside a bundle, but it doesn't seem to work for the native version. Does anyone have any suggestions for putting inkscape native into an application bundle? -- Matthew Peterson Programmer Christa McAuliffe Space Education Center On Fri, Jun 20, 2008 at 3:39 PM, Matt Peterson <revcompgeek@...400...> wrote: > Looks like both were problems.

quick note on "using"
by Jon A. Cruz 26 Jun '08

26 Jun '08

Hi, Just a quick little note on the use of "using namespace" and such in .h files. Please don't have "using" in .h files, since that ends up contaminating any .cpp files that include the .h. Also any that include .h's that in turn include .h's that do... ... but then we get into my personal preference to avoid #include inside of .h's when possible.
