Re: [Inkscape-devel] 0.91 performance when zoomed in (Saar Drimer)

Hello Saar, Indeed you found your culprit, but added to that I see a lot of transparency objects in your design. If you have many layers as your design does and each of those has transparent objects in them I can imagine that things got a tad slow. Instead of a simple integer being used to display a single colour every layer of transparency needs to get calculated, added to the the previous one using floating point calculations. I imagine that this is handled on a logarithmic scale 1,2,4,8 etc. per layer used or per overlapping object. If your bottom layers were masked stacks of the same type of objects, I can imagine that the calculations of the masks are applied after going through the whole object stack calculation. Maybe using clips instead would make the result faster as well as those are simpler calculations to my knowledge. In any regard using lots of floating points explains the delay in screen refresh as well. It certainly isn't the amount of nodes. Cheers, Jelle

Escher Sketch and interactive tiled cloning.
by Mark Schafer 06 Apr '16

06 Apr '16

Anyone seen this: - https://levskaya.github.io/eschersketch/ Works quite well as a live sketch tiling tool. Possibly misnamed. I see we have many of these reflection modes which can only be reached via Edit/Clone/CreateTiledClones... The modes for which are explained here: - http://wiki.inkscape.org/wiki/images/WallpaperTransformations.png linked from here: - http://wiki.inkscape.org/wiki/index.php/OnCanvasSymmetryTool I can see several pages here and there on proposals for an interactive UI. E.g. the one above, http://wiki.inkscape.org/wiki/index.php/Tiled-Clones It seems the paths can't be edited after tiling. I may be wrong about this but I can't work it out. (Only one shape can be selected at a time when hitting Create. I guess you have to group them first) I found this tutorial - http://tavmjong.free.fr/INKSCAPE/MANUAL/html/Tiles.html I seem to recall a lot of UI work was done on a way to make his work - maybe a year or more ago. I'm clearly using the wrong google search terms :( Did any of it make it into a release ? GSOC ?

0.91 performance when zoomed in (Saar Drimer)

Saar, Can you take a look at the objects using the XML editor and see what that tells you? To me it sounds like you may have some opacity or blur filters still going on. Also when you use the no filter display, is it still the same? That should give a decent clue as to what is going on. Cheers, Jelle

Hackfest catering and venue information
by Alex Valavanis 04 Apr '16

[Can ignore if you're not attending the Hackfest!] Hi All, Some information about the Hackfest venue, and a request for your dietary requirements... == Venue == The Hackfest venue will be in the Evans Room at Devonshire Hall in the Hyde Park area of Leeds [1]. It is a traditional "Oxbridge style" stone-built hall. Our meeting room will accommodate 10 delegates. == Catering == A buffet lunch will be provided each day. I will suggest that we break for lunch at 1300 each day, unless there are any objections. Please let me know by tomorrow if you have any special dietary requirements. There will also be an unlimited supply of tea, coffee and biscuits. Sugar, milk and soy milk will be provided. == Facilities == * Wireless networking * UK mains power (remember to bring your own socket adapters if you're coming from outside the UK!!) * Data projector & screen * Flipchart and pens == Nearby amenities == There are a few pubs, bars, cafes and coffee shops 5 minutes walk away from the venue if we want a change of scenery. There is also a small convenience store. The venue is located on the Woodhouse Ridge nature trail if you want to step out for some fresh air [2]. == Local contact == I live within walking distance of the venue. Send me a message if you get stuck! I'll also be free on the Sunday evening before the Hackfest if anyone would like to meet for food/drink in Leeds City Centre. Best wishes, Alex [1] http://www.meetinleeds.co.uk/devonshire-hall [2] http://www.woodhouseridge.org.uk/

Re: [Inkscape-devel] Proposal for building Windows devlibs and for windows build environment setup
by Michael Soegtrop 02 Apr '16

Dear LRN, > 1) I would suggest MSYS2 to be used (instead of Cygwin), as a shortcut, as > it cuts down the number of packages that need to be built. Using MSYS2 > might also be faster (because compatibility layer will be thinner than Cygwin). I made quite extensive tests of cygwin with MinGW cross vs MSys2 and came to the conclusion that cygwin requires much less patching and messing around than MinGW for building most libs. The only advantage of MSys2 is that GTK and all its dependencies are available pre-built, but the MinGW GTK build on cygwin is fairly straight forward, it just takes build time. On cygwin I mostly use a generic download / configure / make / install shell function for building. Some libraries need a patch or two, but with cygwin this is the exception, not the rule. I think that maintainability and cleanliness is more important than build time, since most people won't touch the libs and build them at most once a quarter. As long as it is fully automated, I don't care if it takes 3 hours. Another reason I finally settled with cygwin is that the scripts are 99% identical to what is needed for a cross build on Linux. The deviations with MSys2 tend to be larger. But I guess this is a topic one can argue about forever. How about we share our scripts, experience and ideas and work on both MSys2 and cygwin+MinGW in parallel and see what is easier in the end? Most of the work is solving specific build issues and it would be great to have someone to discuss this. I would suggest that we take this off list. I send you my scripts stripped down to what is shared between inkscape and my original project later today via private mail. Best regards, Michael

Git
by Krzysztof Kosiński 02 Apr '16

Eventually we probably need to move to Git. The user interface is completely atrocious, but the fact it works from a single directory by default is very convenient when using Eclipse, and Eclipse is an elephantine monstrosity but has good code navigation. This could also encourage more people to contribute, since almost all OSS developers know Git, while a very limited number know Bazaar at this point. The bug tracker and answer tracker should definitely stay on Launchpad, but what about the code? Should we use Launchpad's nascent Git support, or some other site like Github? What people think? We can convert lib2geom first and apply the lessons learned to Inkscape. Best regards, Krzysztof

Proposal for building Windows devlibs and for windows build environment setup
by Michael Soegtrop 02 Apr '16

02 Apr '16

Dear Inkscape Team, I have a proposal for improving the delivery for the windows libs and for setting up a build environment. The current method of delivering binary libs has two disadvantages: 1.) it restricts the user to a very specific binary gcc build (at least the docs say so). 2.) it is tricky to check if this delivery method is GPL compliant. According to GPL if you deliver binaries you also have to deliver sources, and it is a lot of work to check all libs licenses and to check if all required sources are in the delivery. Please note that it is NOT sufficient to say "this is standard GPL software and you can download the sources from the official sources". If you delivery binaries, you have to deliver the sources. Now to my proposal: for another open source project I created 2 scripts: one which automatically sets up a fresh cygwin with MinGW cross support and whatever else is needed and another one which downloads and builds a bunch of libraries and apps from sources, including GTK, cairo and pango. About 70% of the libs inkscape requires are built by this script, so it wouldn't be that much work to add the remaining 30%. This does not just setup a build environment and builds everything automatically, it also documents exactly what was used and how it was built (and possibly patched). So my proposal would be to instead of delivering the libs as binaries and lengthy instructions just deliver these two scripts. The scripts are fairly simple and well documented. The build for inkscape and all its libs from scratch would likely be 2..3 hours on a decent machine. Would others appreciate such a mechanism to build inkscape on windows? Usually it would be a single call to a DOS batch file to setup cygwin and start the download and build process. Best regards, Michael
