win32 build working again
by Bob Jamison 08 Apr '24

08 Apr '24

The win32 build, which was broken for the weekend, is working again. I just made a "manual autobuild" again, so that we can see how it looks on Windows: http://troi.titan-aeu.com/~rjamison/inkscape/builds/ Bob

Smooth transitions in Bézier paths
by Diederik van Lierop 11 Nov '08

11 Nov '08

Hi, I hope you don't mind if I increase the traffic on inkscape-devel even more ;-) At some point an idea popped up to only snap to nodes at discontinuities in paths, and not to nodes at smooth transitions from one Bézier segment to another. This is more intuitive (less "Hey, what it is Inkscape snapping to now?") and might increase performance. Problem is that in the object-snapper I only have access to SPCurve, which is a wrapper for "old-style" NArtBpath. It's easy to find out whether a point is inbetween two Bézier segments, but how do I find out if a transition is smooth? I guess that should be done by comparing the control points, or is there an easier way? With the transition to lib2geom, will the NArtBpath be deprecated in favor of the Path class? (that would make this rather exercise useless in the long run). Any pointers would be appreciated here, Diederik

question regarding wishblade robocraft support...
by stuart 03 Sep '08

03 Sep '08

Sorry for posting here if the user list if better. And sorry about the subject if it has been talked about before. I couldn't get sourceforge to add me to the inkscape user mail list and sourceforge was timing out on all my archive searches with no results. --- I remember reading that there was a patch or something to inkscape to support wishblade and robocraft users. Has that been integrated into the inkscape application? Is that what the DXF is all about? Wishblade users can not use DXF directly (needing the robocraft software to import DXF and change it to some sort of native (and maybe proprietary) GSD). Is there a way to get inkscape to save images in GSD in order to simplify the process? Ideally, I would prefer to skip bringing up the wishblade application. In my set up, I do all my work in linux (GIMP/INKSCAPE) and only the plotting in Windows. If I could do everything in linux it would simplify the flow of work greatly. Has anyone figured out how the craftrobo is communicated to in order to use it with common open source linux plotting software? Better yet, has anyone figured out how the wishblade has been crippled in order to use it with common open source linux plotting software? ...thanks

inkscape git mirror?
by MenTaLguY 18 Jun '08

18 Jun '08

I'm interested in setting up a git mirror of Inkscape SVN; who's the person in charge of our server currently? We'll need to have a fairly current version of git, libsvn, and the libsvn perl bindings installed to do this. -mental

Fwd: Programming for Inkscape.
by bulia byak 05 Jun '08

05 Jun '08

...forwarding this to the devel list... ---------- Forwarded message ---------- From: Pam B. <pamely@...329...> Date: Thu, Feb 14, 2008 at 2:26 PM Subject: Programming for Inkscape. To: buliabyak@...400... Hi, I have been told to contact you by Bibi Morris. I understand that in the past some wonderful people have made changes in Inkscape that made it an incredibly useful program for owners of Wishblade and CraftRobo personal media cutters. I have now been provided a tip that would allow users of Linux to drive their machines directly from Inkscape. The "tip" suggested that Windows users might be able to do the same if someone was able to do something with the windows binary for Inkscape. As is probably already obvious, I know nothing about Operating Systems, nor do I know anything about coding and software programming. Actually, I no longer even own a Wishblade, (I have moved on to a bigger machine.) but I do run a support group for over 1,000 personal cutter owners. This has the potential of being a very powerful tool to owners of these types of cutters and could save them hundreds of dollars in software upgrades. Would you please check into this and see if it is something that can be done for us? Thank you, Pam Beard and the 1,000+ in the yahoo group: EasyWishbladers The "tip" is pasted below: If the words Linux, RedHat, Debian, Inkscape and / or Python mean anything to you read on (warning, getting technical here...). How would you like to cut from inkscape? all in Linux? I have been lurking in Linux Printer Driver land and was very happy to find an early copy of a Python script designed to provide the necessary "linkage" between Inkscape and a craftrobo cutter. With a little change to the code, we verified it works with a wishblade as well. But you might have to wait until there is support in the down loadable python script. Basically, you print from Inkscape "using PostScript operators" (not as a bitmap). And, instead of sending the output to a printer, you "pipe" it to the python application. This operation is actually described in the Inkscape print popup menu. When you click on print, the python GUI pops up giving you more options. This GUI interface is *much* simpler than the actual graphtec software. Most anything to do with the image needs to be done in Inkscape. The only real control on the GUI are the paper size, the cutting speed and the cutting pressure. I suppose this can also be done in windows. My *assumptions* are that there is a windows binary for inkscape as well as python and python related software. If that's the case, then you may be able to skip setting up a Linux box. I know I am hitting only about 1% of you, but if you want to try the script you can get it here: http://vidar.gimp.org/graphtecprint/ ....I am sure feed back at this stage of development would influence what features are fixed, enhanced and / or added. -- bulia byak Inkscape.

tar-pax option in configure.ac
by John Bintz 25 Mar '08

25 Mar '08

Ted, Myself and others have been having problems building Inkscape since r17648, when you added the option for the tar-pax format in AM_INIT_AUTOMAKE. Ubuntu Gutsy, which I'm running, and Fedora Core 6, according to some mailing list traffic, don't have a new enough version of automake in their standard repositories to run ./autogen.sh successfully with that option enabled. Other distributions may be involved, too. Using automake1.8 and removing the tar-pax option get ./autogen.sh to work, and I'm wondering what you would think about rolling back the tar-pax option for now, to ease the problems that users of those operating systems are having with building Inkscape, and then re-enabling it later, when the repositories for those distributions upgrade to the newer automake1.10. Thanks, John

Snapping to nodes (within same path)
by unknown＠example.com 10 Mar '08

10 Mar '08

Hi all, Mostly to Diederik: can nodes of a path snap to nodes of the same path when nodeediting them? It seems they can't, but perhaps I should switch another toggle somewhere?

Hey, So I think that this patch fixes a bunch of the extensions problems, many of them on win32. Can someone test it on Windows for me? Thanks, Ted
