Window to Gif script

Here are the script we speack at hackfest I use to record the gifs on 0.92 release page: Need beep and byzanz-record use as : ./recordToGif.sh 60 /path/to/file.gif where 60 is 60 seconds select the window to record... --------------------------------------------------------------------- #!/bin/bash # Delay before starting DELAY=3 # Sound notification to let one know when recording is about to start (and ends) beep() { /usr/bin/beep } # Duration and output file if [ $# -gt 0 ]; then D="--duration=$@" else echo Default recording duration 10s to /tmp/recorded.gif D="--duration=10 /tmp/recorded.gif" fi XWININFO=$(xwininfo) read X < <(awk -F: '/Absolute upper-left X/{print $2}' <<< "$XWININFO") read Y < <(awk -F: '/Absolute upper-left Y/{print $2}' <<< "$XWININFO") read W < <(awk -F: '/Width/{print $2}' <<< "$XWININFO") read H < <(awk -F: '/Height/{print $2}' <<< "$XWININFO") echo Delaying $DELAY seconds. After that, byzanz will start for (( i=$DELAY; i>0; --i )) ; do echo $i sleep 1 done echo ":::::::::::::::::::::::::::::::::::::::::::::::::::::::" beep byzanz-record --verbose --delay=0 --x=$X --y=$Y --width=$W --height=$H $D & read FULLDURATION FAKE <<<$(IFS=";"; echo $D) read FAKE DURATION <<<$(IFS="="; echo $FULLDURATION) for (( i=$DURATION; i>0; --i )) ; do if [ $i -ne $DURATION ]; then echo $i Segundos fi sleep 1 done beep

[Fwd: OpenSource library for Biharmonic Diffusion Curves]
by Bryce Harrington 06 Jul '15

06 Jul '15

----- Forwarded message from barla <pascal.barla@...3252...> ----- Date: Mon, 06 Jul 2015 17:18:51 +0200 From: barla <pascal.barla@...3252...> To: tavmjong@...8..., th.v.d.gronde@...528..., j.b.c.engelen@...3066..., bryce@...961... CC: Gael Guennebaud <gael.guennebaud@...3253...>, Simon Boyé <sim.boye@...1761....400...> Subject: OpenSource library for Biharmonic Diffusion Curves Hello, We had discussed by email quite a long time ago about a library we were working on that implements Biharmonic Diffusion Curves. We eventually released a first version a few weeks ago, as part of our Patate Library : http://patate.gforge.inria.fr/html/vitelotte_user_manual_page.html It implements the paper "A vectorial solver for free-form vector gradients <http://dl.acm.org/citation.cfm?doid=2366145.2366192>" (I've put my co-authors in CC). Starting from a mesh with constrained curves or points, it provides routines for harmonic and biharmonic diffusion using FEM. Do not hesitate to give us feedback on the library module ! In particular, we wonder how it could fit in (or be converted to) the SVG format. A new version of the library with a few new features (color spaces, Bezier curves) should be out during the summer. Best regards, Pascal Barla. ----- End forwarded message -----

Inkscape in the wild - seen in Tel aviv
by MichaelGrosberg 06 Jul '15

06 Jul '15

So I was walking near the Tel Aviv municipality building yesterday and noticed that the entire side of the ground floor was covered with a large abstract mural composed of multiple shapes. Started looking at the shapes and noticed: spirals, 3D boxes, shapes filled with a vertical stripe patterns, pie slices... And it dawned on me that it MUST have been created in Inkscape! You can see photos of the mural here: http://bit.ly/1euwWvS (I had to shorten the link - the original link has hebrew characters in it and I can't paste it correctly) The page is in hebrew but you can see the photos. The text next to the mural says the artist's name is Nurit David, that the mural has somethign to do with Peter Bruegel's "The Triumph of Death" and that the digital nature of the work has something to do with the transience of time (I'm heavily paraphrasing, translating art-speak between two languages is nearly impossible).

Inkscape_trunk_scan-build - Build # 120 - Unstable!
by Jenkins (build tester) 05 Jul '15

05 Jul '15

Hi developers, Clang scanbuild found a potential bug in recently committed code. Inkscape_trunk_scan-build - Build # 120 - Unstable. See here which bugs were found (new in red): http://jenkins.inkscape.org/job/Inkscape_trunk_scan-build/120/clangScanBuil… It is paramount to keep our codebase clean with as little compiler warnings as possible, so we can swiftly eradicate newly introduced bugs, to keep Inkscape stable and prevent lengthy dragging bug hunts before releases. Your friend, Jenkins http://jenkins.inkscape.org

About hidpi support
by Pengfei Hao 05 Jul '15

05 Jul '15

I am using Lenovo Yoga 2 Pro with resolution 3200x1800, gnome 3, the icons, axis fonts, look so small. Some buttons, texts, have overlapping. I noticed that this already reported on bug tracker on launchpad a long time ago. https://bugs.launchpad.net/inkscape/+bug/1285887 I just want to know if there is any update of the hidpi support? Is it on the going or no buddy even care about it?

gears Path effect
by Mark Schafer 05 Jul '15

05 Jul '15

I just saw this in this video. Somehow I did not notice it before :( - https://www.youtube.com/watch?v=DTbYHmQkY9w - generates a meshing gear at each point on the path and remains editable (of course) Is it possible for me to redirect its "gear" call to the new gears plugin here: https://github.com/jnweiger/inkscape-gears-dev Is it envisaged in the future to allow this to be python scriptable (I assume its all embedded c at the moment) ?

Boolops progress
by Krzysztof Kosiński 04 Jul '15

04 Jul '15

There is a new toy "boolops-new" in 2Geom's source repository - it computes an union of two paths using my new boolops code based on the Greiner-Hormann algorithm. What works: - Union - Intersection - Adding difference and XOR is trivial - Linear and Bezier segments of arbitrary degree - Code is fairly clean and understandable - Reasonably good performance, even though there are very few optimizations What remains to be done: - Could be simplified a bit and better documented. - Intersection procedures for arc-arc and arc-Bezier cases. Currently they throw UnimplementedError. - Handling of degeneracies and second-order intersections. I have this mostly planned out, except for a few nasty cases with overlapping Bezier segments. - Add &, |, / operators to PathVector. I think / will be better than minus for set subtraction. - Function that converts a nonzero winding pathvector to even-odd winding pathvector with the same filled areas. It's a lot easier to do this conversion than it is to do Booleans on nonzero winding fills. I observed no crashes or hangs, though when two pathvectors overlap exactly, some paths can be skipped in the output. Since this code is already a lot better than the old attempts present in 2Geom (path-intersection.h, shape.h, region.h and the like), I'm going to remove them to reduce cruft. Regards, Krzysztof
