Proposed gradient editor
by Stathis Sideris 25 May '07

25 May '07

Hello everybody, I am writing to propose an enhancement on the way stops are defined and edited in the gradient editor on Inkscape. Sorry for cross-posting to the user and devel lists, but I would like feedback from both crowds. The idea is that the stops of the gradient are shown as circles on a larger gradient preview area, with the X axis representing the offset of the stop and the Y axis representing the alpha of a particular stop. Also, note that the circles contain the colour that corresponds to the particular stop. Please see the attached diagrams. Despite being a programmer myself, I won't be able to implement this feature right now, mainly due to my limited C++ ability and lack of familiarity with the Inkscape codebase. Hopefully someone will like it enough to give it a go. It would be great to see what people think. Stathis

PDF to SVG conversion with libpoppler and cairo
by Dave Barton 24 May '07

24 May '07

Hi, I noticed that one of the SoC'ers is working on integrating libpoppler with Inkscape for PDF import - I have investigated this briefly and written a quick-and-actually-not-too-dirty PDF to SVG converter with libpoppler and cairo. It is available at <http://seis.bris.ac.uk/~db9052/pdf2svg.tgz>. It is a *very* simple program that opens a PDF file with poppler and renders it to a cairo surface that is connected to an SVG file. Very simple and very effective and you might want to think about integrating it with Inkscape as is. It has worked on everything I've tried it on, though it has the nasty habbit of slicing large bitmaps up into small chunks. It doesn't produce the most streamlined SVG files either... Try it out and let me know. Dave -- =========================================== David Barton Email: davebarton@...1739... Web: www.cityinthesky.co.uk ===========================================

SoC blogging
by Niko Kiirala 24 May '07

24 May '07

I've put up a blog about my summer project. I'm planning to post there frequently about what I've been working on: http://fedev.blogspot.com/ Unlike this Finnish SoC project I'm working in, GSoC doesn't require writing this kind of documentary. Seems like Gail Banaszkiewicz put up a blog already, how about the rest of SoC:ers here? And yes, consolidating these blogs somewhere sounds like a good idea. Planet Inkscape maybe?

inkscape + olpc efforts
by Jon Phillips 23 May '07

23 May '07

Hi all, could anyone who is interested in taking a contract and or in a position to consider working on the OLPC, please email me offlist. I have some leads on funding to get inkscape ported to OLPC asap. Really, it will be some very very cool work. You might send me what you would like to get from this kind of gig...I mean $$$, etc... I also have put in for 2 olpc machines that we can pass around between inkscape developers. I'd like to get a short paragraph from developers who could honestly contribute to OLPC + Inkscape efforts to get one of these machines. So, also, please send this request to the mailing list. Oh, I forgot to mention that OLPC wants to use Inkscape as the default drawing activity on the device...this is like millions of Inkscape users if they ship as many OLPCs as they say... Cheers!

Help on a web svg2png service
by Aurélio A. Heckert 22 May '07

22 May '07

Hi Devels! I'm trying to re-make an svg2png service on the web using the Inkscape 0.45, but it is not working. I'm using the inkscape by the command line in a server without X with this command: inkscape $svg -z -h 160 -e $png If i connect by SSH i can use this command and works! But if my PHP code try this i recive this error: (inkscape:3946): Gtk-CRITICAL **: gtk_main_quit: assertion `main_loops != NULL' failed What is missing? If I run the PHP by the commad line: php index.php 'http://upload.wikimedia.org/wikipedia/commons/1/15/Svg.svg' it works! What is diferent on the apache? Whay the GTK gives error? Se that on debug way: http://www.colivre.coop.br/svg2png/?debug=1&svg=http%3A%2F%2Fupload.wikimed… The ENV by apache is only "SHLVL=2" And on the SSH is only "LESSCLOSE=/usr/bin/lesspipe %s %s" You can see the PHP code hire (if need...): http://www.colivre.coop.br/svg2png/index.phps It works with Inkscape 0.44 I thing there is a bug on the 0.45, because it is trying to do somenting with the GTK main_loops, but i used the "-z" (without gui) Thanks, Aurium -- -===================================================- . .

PS and EPS input with pstoedit
by jiho 21 May '07

21 May '07

Hi everybody, There were several discussions in the past about dropping the requirement for sketch in PS and EPS input. pstoedit can be used instead, with its plot-svg backend (which is free, don't confuse it with the non-free "svg" backend). I produced a patch to do this, which waited in the tracker for a time. https://sourceforge.net/tracker/? func=detail&atid=604308&aid=1629798&group_id=93438 I just committed it today (r15046) to see what happens. Apparently it has been used in Fedora's Inkscape for a while so it should be quite safe. However it still causes warning messages to appear and some strange zooming behavior depending on the source of the EPS/PS file. I would appreciate feedback and advise on this. Cheers, JiHO --- http://jo.irisson.free.fr/

Debian package of Inkscape and printing with CUPS
by Daniel James 21 May '07

21 May '07

Hello, We ship the Inkscape 0.44 package from Debian Etch in the 64 Studio creative distro, and lately the printing support for local CUPS printers seems to be completely broken. There has also been a Debian bug opened, see: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=423952 Does anyone have Inkscape printing working on Etch, without resorting to lpr or another old-school method? In 64 Studio, even manually pasting the output of lpstat -p into the Print dialogue box makes no difference, printing just fails silently. Any tips would be greatly appreciated :-) Cheers! Daniel

LPE in SVG - defs type 2
by unknown＠example.com 19 May '07

19 May '07

I have added another type to the LivePathEffect discussion on SVG representation. See http://wiki.inkscape.org/wiki/index.php/LivePathEffects_Discussion. FIRST: <inkscape:path-effect xlink:href="x-inkscape-plugin:org.inkscape.effect.skeletal" id="path-effect2"> <inkscape:param name="skeleton" type="path" value="M 0,0 L 2,2 L 4,0" /> </inkscape:path-effect> SECOND: <inkscape:path-effect id="path-effect2" effect="skeletal" skeleton="M 0,0 L 2,2 L 4,0" /> You should be able to infer the type from the specified effect and parameter name. So for the first one, there may be strange bugs when the parametertype is entered wrong! And what if there are two children with name="blah"? While I was coding for some reason I thought there was too much freedom. That's why I came up with the second one. It cleans the SVG up a little aswell. Also, xlink:href="x-inkscape-plugin:org.inkscape.effect.foo" seems overly verbose. The second proposal has a minimal effect specification (probably too minimal). Thanks for all your input and comments. In the meanwhile I will start implementing the second one. If we want to go to the first or some combination or something completely different, at least I have the coding experience of the 2nd one :) Cheers, Johan

Live Path Effects - how to specify in SVG?
by unknown＠example.com 19 May '07

19 May '07

Hi all, I already have live effects working for a bit (see the live-path-effects branch). Now I want to focus on how to write things to SVG. On the following wiki page, I have put some alternatives that I found in a mail discussion a year ago. http://wiki.inkscape.org/wiki/index.php/LivePathEffects_Discussion What do you think is the best solution? The defs and <inkscape:patheffect> ones are my favorites. Feel free to svn checkout the branch and play around! (see \share\examples\live-path-effects.svg) Cheers, Johan

Inkscape Pages on SVG Bug #1657607
by Aurélio A. Heckert 19 May '07

19 May '07

Hi, ther is a proposal for implement pages on Inkscape: http://sourceforge.net/tracker/index.php?func=detail&aid=1657607&group_id=9… I put a comment now extending the proposal to add a master page functionality. I thinck it is very very important for an serious multi-page layout tool. The Milestone 15 - Inkscape 0.49 is seted to implement the multi-page proposal: http://wiki.inkscape.org/wiki/index.php/Roadmap#Milestone_15_-_Inkscape_0.4… Is the bug #1657607 the right place to comment the multi-page behaviour?
