i'm also interested on this about using Python as scripting language - specially after what i saw about Scriptographer on Adobe Illustrator, and how can Inkscape do the same with Python maybe the less worse idea is trying to learn from what were made up to now? i'm as well having difficulties on coding picture filters with Python-Fu (Gimp) -------------------- On Mon, Jul 28, 2008 at 11:14 PM, <inkscape-user-request(a)lists.sourceforge.net> wrote: > Send Inkscape-user mailing list submissions to > inkscape-user(a)lists.sourceforge.net > > To subscribe or unsubscribe via the World Wide Web, visit > https://lists.sourceforge.net/lists/listinfo/inkscape-user > or, via email, send a message with subject or body 'help' to > inkscape-user-request(a)lists.sourceforge.net > > You can reach the person managing the list at > inkscape-user-owner(a)lists.sourceforge.net > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Inkscape-user digest..." > > > Today's Topics: > > 1.

Fix for latency warnings
by Jon A. Cruz 26 Jul '08

26 Jul '08

For those seeing the recent event latency warnings, I've just put in a fix ** (inkscape:27965): WARNING **: Event latency reached 3.290566 sec The main cause of extraneous warnings is a slight difference between the clock used for the GDK event marking and the real time. On my Mac, I observed that the skew was of a constant factor, so I added in an option to compensate for that. On my system the value was 0.9766 (and thus on my system after running for 85 seconds Inkscape would believe a latency of over 2 seconds had crept in). We'll probably need to investigate this a bit more, but getting that factor in should let people with false warnings get things calibrated and see only good ones. If you need it, look for the new setting under the misc pane.

tablet stuff
by Alexander Roalter 23 Jul '08

23 Jul '08

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Since upgrading to OpenSUSE 11, I got the following problem with inkscape, both 0.46 and SVN: If I set the extended input preferences of the Stylus to 'Disabled', I can use the pen as a mouse, draw etc. and move things around, but I don't get any pressure sensibility. It I set the extended input preferences to 'Screen' or 'Window' (preferrably to 'Screen'), I get pressure sensibility, but I cannot select any object by simply clicking on it. I have to tap multiple times on it in order for it to have the normal handles appear, and only then I can move the object around. If I tap too often, I get the node selection, which isn't what I want (at that moment). Any Ideas on why? Is this something the X input does differently when XInput is set to screen so Inkscape does not register a press (or doesn't register it in the right way?) or is the code in inkscape for disabled and screen mode that much different so that selecting with screen mode won't work as expected? - -- Cheers, Alex -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (GNU/Linux) Comment: Using GnuPG with SUSE - http://enigmail.mozdev.org iEYEARECAAYFAkh+hGkACgkQ1J0MF2u394w5rQCgs22t2U1MLYZtlo9E6RxNL2B/ FtoAoIKLqZvS6W7l3RoYYv1pEnQs9t+h =EkZv -----END PGP SIGNATURE-----

Re: [Inkscape-user] INkscape on windows XP

John, Installing on Slackware 12.1 worked ok for me. I needed to install the GC garbage collector from here: http://www.hpl.hp.com/personal/Hans_Boehm/gc/gc_source/gc.tar.gz Then I ran the Inkscape configure script: ./configure without any additional options. Then make, and make install. I did that after installing Gnumeric which needed 2 preliminary items installing. goffice-0.6.4.tar.bz2 intltool-0.40.0.tar.bz2 gnumeric-1.8.3.tar.bz2 - install with ./configure, no additional options. I wonder if these Gnumeric things supplied anything needed by Inkscape? I'm not sure. Inkscape and Gnumeric are essentials that I really miss now Slackware has dropped Gnome - fortunately it wasn't too difficult to install them.

HSL colour picker
by Roger Keays 21 Jul '08

21 Jul '08

Hi, I noticed Inkscape has a HSL colour picker, which is great. Is there any way to change the scale of the components though? i.e: H: 0 - 360 S: 0 - 100% L: 0 - 100% The default setup has values from 0-255 for all three components. /me is no good at 8-bit mental calculations ;) Roger -- Sunburnt Software www.sunburnt.com.au +61 7 3117 9661

INkscape on windows XP
by John Culleton 18 Jul '08

18 Jul '08

I know I can put up a Debian or derivative partition (Ubuntu, Kubuntu, Mbotu etc.) and get to Inkscape 46 fairly painlessly. I also have already an unused Win XP partition. My question is, does Inkscape 46 download painlessly to Win XP or is it one of those kludges where you have to download this to compile that to support something else? I am looking for the easiest path to a fully functioning IS 46. My main partition is of course Slackware 12 but you really don't want to know what I have been through already trying to install IS 46. -- John Culleton Resources for every author and publisher: http://wexfordpress.com/tex/shortlist.pdf http://wexfordpress.com/tex/packagers.pdf http://www.creativemindspress.com/newbiefaq.htm http://www.gropenassoc.com/TopLevelPages/reference%20desk.htm

SVG web programming OT?
by Patrick 17 Jul '08

17 Jul '08

I hope I am not too far off topic here...... There are quite a few resources out these concerning programming SVG graphics but I have not found much of anything concerning SVG web programming. What I mean to say is, how do I take an SVG document and add hyperlinks, css, javascript, etc , to make that document a rich full fledged web site?-Patrick

INKSCAPE GALLERY RC2 ------draw freely...then publish!-------
by davide|inkscapegallery 15 Jul '08

15 Jul '08

There's a lot to say about this new release...you might prefer to see it immediately..so, start from here: http://inkscapegallery.net/home I worked hard for three months to build gimpgallery (http://gimpgallery.net)and it has been recently released... So i had many ideas about how to improve inkscape gallery, i was tired and anxious at the same time... The second feeling won and i'm here to list what i've done in the last days: *The home page* It is a complete section with 4 subsections, "from the inkscape's world", "highlight on", "special sections" and "a little taste of inkscpae gallery". *4 new sections called:* fresh, mostvoted, older and popular *The "inkscape galleria"* it is a slideshow made with a jquery plugin labeled "galleria",indeed. It is quite smart and fast, just to give you another way to see what is best in inkscape gallery: images! *The user's "inkscape galleria"* Every user has his own "galleria" , just click on the link in the title block of each image content *Some layout improvements* In a big website you will always have something you fixed with a workaround, not in the best way, in other words... I've found better solutions now *The "from the inkscape world" section* It is the upper section in the home page. This was not an hard work but is important i mean, just because i'd like to work together with other inkscape based website. *The wysiwyg editor* we have a simple wysiwyg editor now. It works only for logged in users, anyway *The antispam framework* we've never had critical spam problems, you can directly publish in inkscape gallery only when logged in, indeed. we have user profiles, with an email field and i wanted to keep it safe from spam even if you need to be logged in to view the user profiles... (maybe not anymore in the future...) Anyway, the email field is protected from spam, now *The gimpgallery promo* I wanted to make you know about gimp gallery. It is another image gallery website for a free image editor and it is even more advanced compared to inkscape gallery, actually. It is freshly born and quite empty, i had to borrow some images from inkscape gallery so, if you're a gimper, go there to publish your images! This is what, i hope you to like it, there's always something to fix, to improve but that's inevitable (especially on IE) :-) i'm planning the next steps to bring inkscape gallery to the next release! See you, and keep drawing! Da. http://inkscapegallery.net
