Crash when applying patterns
by Maximilian Albert 30 Jun '08

30 Jun '08

Hi, since a short while ago, applying a pattern to a path in the fill/stroke dialog has led to a crash. I have found out that this is caused by invalid path data in share/patterns/patterns.svg which was introduced in revision 16619. Namely, there are stray minus signs (without a number following them) at two places in the code, like this: C -152.421,-34.897 -132.804,-34.567 -147.875,- L -150,-46.156 z (notice the isolated minus sign in front of the L). I committed a temporary "fix" by just inserting the value 999.999 for the missing coordinates (this makes it easy to find them in the file). Of course this messes up the patterns but I don't know the correct values for the missing coordinates. Bulia, since you committed the new patterns, could you have a look and properly correct them? BTW, were the paths created using Inkscape? In this case we should also find out why the invalid path data was produced in the first place. Max P.S.: Note that there still is another bug related to patterns which leads to a crash when you want to edit patterns using their knotholder handles. I wanted to fix it but it was shadowed by the new crash so I couldn't work on it. I hope to resolve it as soon as possible.

Import form openclipart
by Jakub Klawiter 30 Jun '08

30 Jun '08

Hello! Inkscape has great feature to import clipart from openclipart.org, but if there is more than one picture inkscape will import the first one. Same time openclipart will show thumbnail of an image only if first uploaded picture will be raster one (eg. PNG). You can check it here: http://openclipart.org/media/files/wariat/8984 there is no thumbnail but inkscape will import SVG file http://openclipart.org/media/files/jean_victor_balin/8735 there is a thumbnail of a picture but inkscape will import PNG file, while svg is still available. IMO there is a bug on both sides. Openclipart should show thumbnail if there is a raster image on any position of a set. User should not think about this. Inkscape should import any file from gallery, so if there is more than one file in set, it should: - ask which one user want's to download (IMO better) or - show all images in import window. What do you think? -- Pozdrawiam, Jakub. Milion osób dziennie pobiera Firefoksa... pobierz i Ty! www.firefox.pl

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
