Re: [Inkscape-devel] Accessing individual nodes in a path
by Bob Jamison 22 May '08

If you look at the SVG-DOM spec, instead of defining the nodes, they defines the path segments: http://www.w3.org/TR/SVG11/paths.html#DOMInterfaces SVGElement implements SVGAnimatedPathData, which has getPathSegList() and its variants. And the list holds the segments, each of the subtypes of which has the node data. bob -----Original Message----- >From: Maximilian Albert <Anhalter42@...173...> >Sent: May 21, 2008 9:20 AM >To: inkscape <inkscape-devel(a)lists.sourceforge.net> >Subject: [Inkscape-devel] Accessing individual nodes in a path > >Hi, > >for a couple of applications I have in mind it would be very desirable >if one was able to access and refer to individual nodes in a path in a >way that is unaffected by future insertion/deletion of other nodes (in >much the same way as accessing the members of a linked list is >unaffected by insertion/deletion of other elements). > >How easy would it be to achieve this, especially considering the change >of path representations to 2geom?

Path intersection, union, difference code
by Frederich, Eric P21322 21 May '08

21 May '08

Hey guys, I'm writing a program that generates SVGs. I realized how big of a pain paths are. Right now I am basically just doing straight lines. The curves that I do have are radii and they're all 90 degree semi circles. Those were a pain too, luckily I stumbled upon http://www.whizkidtech.redprince.net/bezier/circle/ and I can create them in my paths. Anyway, I'm at the point where I need to start doing some more complicated things. I can do these things easily in Inkscape but I'm finding it difficult to generate the path data directly. I am wondering where in the source of Inkscape I can find the routines that do the intersection, union, and difference of paths so that I can incorporate it into my code. Thanks, ~Eric

Accessing individual nodes in a path
by Maximilian Albert 21 May '08

21 May '08

Hi, for a couple of applications I have in mind it would be very desirable if one was able to access and refer to individual nodes in a path in a way that is unaffected by future insertion/deletion of other nodes (in much the same way as accessing the members of a linked list is unaffected by insertion/deletion of other elements). How easy would it be to achieve this, especially considering the change of path representations to 2geom? What would be necessary to implement it? Can this be easily integrated into existing path representations? Max

NEW: SVG Output preferences
by unknown＠example.com 20 May '08

20 May '08

Hello all, I have exposed the SVG Output preferences in a new tab in the preference dialog. Because of some of the preferences I am not too sure what they do, the tooltip text might be wrong. I hope someone who does know can fix them. The "allowshorthands" option seems not used anywhere in Inkscape code. Does anybody know what happened with this option? (I have commented it out, so it does not show up in Pref dialog) Thanks, Johan

categorisation of LPE
by Alexandre Prokoudine 20 May '08

20 May '08

Hi, There are 15 LPE in the combobox currently and at least Lattice Deformation LPE is going to hit 0.47. Then pluggable LPE are coming. Should we start thinking about catogerisation of LPE before the poor little combobox is overpopulated? ;-) Alexandre

edit image externally
by Felipe Sanches 20 May '08

20 May '08

JonCruz, this is a really nice idea! One little issue: when xlink:href contain a relatve path, gimp does not find the image. Try to edit externaly the image used in share/icons/feConvolveMatrix-icon.svg Its xlink:href attribute is set to "./ticotico.jpg" cheers, Juca PS: I have seen sodipodi:absref="ticotico.jpg" Doesnt absref stand for "absolute reference"? If so, why isnt it storing an absolute path to the jpg file? Also, I guess, absolute paths in xlink:href are evil, since they often only work on the drawing author computer :-P

No default units in dev build Inkscape0805062005.7z
by worms invasion 20 May '08

20 May '08

I have downloaded http://inkscape.modevia.com/win32/Inkscape0805062005.7z yesterday, and tested it. It has a weird problem : no default units are showing, and nothing is showing when I try to use the drop-down menus to select a unit. I am on Windows 2000 - which is known to have problems with drop-down boxes, but nothing can be done at OS level, I believe. Anyway... Has someone the same problem on other OSs? Also, when I enter 10.00 in the box to transform, it becomes 1000000.00, but I can't select "pix". Same in the document properties.

GSL dependency
by unknown＠example.com 19 May '08

19 May '08

Hi all, I just updated Inkscape's copy to the latest 2geom svn rev. I tried to add the GSL dependency to configure.ac but have no way to check whether it has gone wrong or not. I am very sorry if this breaks your build :-( -Johan

isFinite() problem again
by Maximilian Albert 19 May '08

19 May '08

Hi all, recently there was a discussion about name clashes involving is_finite(). The problem appeared to be solved but now I ran into it (or something similar?) again. Namely, adding the line #include "live_effects/effect.h" to object-edit.cpp yielded the following compile error: object-edit.cpp: In function ‘void sp_spiral_outer_set(SPItem*, const NR::Point&, const NR::Point&, guint)’: object-edit.cpp:1121: error: ‘isFinite’ was not declared in this scope When I additionally changed the line #include "isnan.h" to #include "2geom/isnan.h" and replaced isFinite() with IS_FINITE(), compilation worked fine again. Thus it seems that there is some kind of clashing between isnan.h and 2geom/isnan.h. Has anyone else seen this and what should be done to avoid further difficulties in the future? Max
