Re: [Inkscape-devel] Creating guidelines from objects

Hi Max, Op Vr, 11 januari, 2008 20:04, schreef Maximilian Albert: > I just committed a change to SVN (rev. #17022) which allows the user to > convert rectangles and 3D boxes to a collection of guidelines that are > aligned along these objects' edges. That's indeed a very cool feature! I could have used that today at work :-) I have not checked it out yet though, but I wonder: are the guides aligned with the nodes or with the bounding box? Or is there a way to specify this? I ask this because there are essentially two ways of working: either aligning objects at their visual boundingbox, or at their geometrical bbox (or nodes or stroke center). This distinction is being used in the preferences for the selector tool, and also when snapping. So we need it here also IMO. Diederik

Dockable dialog bugs
by unknown＠example.com 16 Jan '08

16 Jan '08

Hello all, Because an (what I thought) important Inkscape-devel 'paradigm' is no longer valid, there are a lot of bugs concerning dockable dialogs: I am talking about having only a single instance of dialogs. Most widgets that I use (the Registered* widgets) are not designed to be managed by others than the creator I think. (like Gtk::Widget is, by using Gtk::manage) It causes for example this bug: https://bugs.launchpad.net/inkscape/+bug/179982 How are we going to solve this for 0.46? Regards, Johan

Frost exceptions status?
by Bryce Harrington 16 Jan '08

16 Jan '08

Hi all, I believe all frost exception development work should now be done, but would like to doublecheck. If you're on the following list, please reply with a status update: 1. Angled guidelines, by J.B.C.Engelen (DONE): Underlying code is complete, and guidelines are rendering, but it needs a UI to allow manipulating them. 2. Python module packaging (lxml, numpy) for OSX, by jiho (ETA ___): Needs wider testing. Needs someone to build PPC packages. 3. Compilation of lib2geom on OS X 10.3 (Panther), by John Faith (ETA ___): An error is preventing builds for Panther versions of Inkscape. If this can't be resolved before release, the alternative is to drop support for this OS version. 4. Font Spec Implementation, by Gail Carmichael (ETA Dec 27). Refactor patch to include some code review changes by Bulia. Also, the patch needs wider testing. 5. Win32 Uninstaller improvement, by Adib (ETA Jan 3). Fix current installer to not bug user for each changed file. 6. PDF, PS export improvements, by Adib (ETA Jan 3). Implement blur as bitmap, and display a dialog with options for text-to-path, blur-as-bitmap, alpha-as-bitmap. UPDATE: Option dialog for PDF/PS exports using cairo are implemented (PDF1.4 and PS3 only). Text-to-path works, for blur as bitmap need help with converting SPItem from vector to image, alpha as bitmap being done implicitly by Cairo 7. Clone Tiling dialog, by Tavmjong Bah (DONE): Add a few options to Shift, Scaling, and Rotation tabs. (TBD: Bug updating blur via Blur/Opacity tab.) (Also, TBD later: some small changes for default values for turbulence and composite filters.) I'd love to hear that all this work is either done, or being safely postponed for the release. If not, let me know, because we need to close all such work ASAP. Bryce

Coding review requested
by unknown＠example.com 15 Jan '08

15 Jan '08

Hi all, Today I restructured/recoded some of the 'registered' widget classes. I'd like someone with C++ knowledge to review svnrev. 17065 and perhaps also svnrev. 17069. I understand it might be difficult because knowledge of how Inkscape uses those widgets is required, but still thanks a lot for just the slightest of critical comment. Thanks, Johan

Hello, I'm a 3rd year computing science student and I would like to help out with your project because I think it's really cool, and your 'project of the month' page seems to suggest that newcomers are welcome. I've never worked on an open source project before; could someone please tell me how I can get started? Maybe I could try to do some small bug fixes. Thanks. Timothy

Printing on XP
by Diederik van Lierop 15 Jan '08

15 Jan '08

Hi all, So far I haven't been able to print anything useful on Windows XP using recent Inkscape versions. My prints (both at work and at home) are 8.3x to small (=600/72 dpi) and have often large black fills or fully black pages. See for example https://bugs.launchpad.net/inkscape/+bug/166561. Is anyone else experiencing this? I think this is pretty serious and should be milestoned, unless ofcourse I'm the only one experiencing this. This appears to be a Windows-only issue, but I'm coding on Linux so I'm not of much help here. Could someone confirm this and maybe even give Kees a hand? Diederik

Re: [Inkscape-devel] Function Plotter Effect

It seems to me that all the parameters on the Range > and Sampling tab are not working. It appears to be a problem the command line parsing. The command line passed to the script looks sorta like like (from ' '.join(sys.argv)): share\extensions\funcplot.py C:\DOCUME~1\NS\LOCALS~1\Temp\ink_ext_XXXXXX.svgVNX14T --id=rect2363 --tab="sampling" --xstart=-50 --xend=20 --times2pi=true --ybottom=-11.600000381469727 --ytop=24.600000381469727 --samples=180 --isoscale=false --polar=false --funcplotuse= --pythonfunctions= --fofx=sin(-x) --fponum=true --fpofx=x --remove=true --drawaxis=false But Python parses it as: ['share\\extensions\\funcplot.py', 'C:\\DOCUME~1\\NS\\LOCALS~1\\Temp\\ink_ext_XXXXXX.svgVNX14T', '--id=rect2363', '--tab="sampling" --xstart=-50 --xend=20 --times2pi=true --ybottom=-11.600000381469727 --ytop=24.600000381469727 --samples=180 --isoscale=false --polar=false --funcplotuse= --pythonfunctions=', '--fofx=sin(-x)', '--fponum=true', '--fpofx=x', '--remove=true', '--drawaxis=false'] And then optparse gets: {'polar': False, 'ytop': 1.0, 'funcplotuse': '', 'drawaxis': False, 'fpofx': 'x', 'ybottom': -1.0, 'ids': ['rect2363'], 'remove': True, 'fofx': 'sin(-x)', 'pythonfunctions': '', 'isoscale': True, 'fponum': True, 'tab': '"sampling" --xstart=-50 --xend=20 --times2pi=true --ybottom=-11.600000381469727 --ytop=24.600000381469727 --samples=180 --isoscale=false --polar=false --funcplotuse= --pythonfunctions=', 'xstart': 0.0, 'xend': 1.0, 'times2pi': True, 'samples': 8} But I think we need to put debug prints in Inkscape to see what the actual command line is that inkscape generates because when I give the same command line options to a simple python script like: import sys print sys.argv I get a properly parsed command line: C:\Documents and Settings\NS\Desktop>cmd_parsing_test.py C:\DOCUME~1\NS\LOCALS~1\Temp\ink_ext_XXXXXX.svgVNX14T --id=rect2363 --tab="sampling" --xstart=-50 --xend=20 --times2pi=true --ybottom=-11.600000381469727 --ytop=24.600000381469727 --samples=180 --isoscale=false --polar=false --funcplotuse= --pythonfunctions= --fofx=sin(-x) --fponum=true --fpofx=x --remove=true --drawaxis=false ['C:\\Documents and Settings\\NS\\Desktop\\cmd_parsing_test.py', 'C:\\DOCUME~1\\NS\\LOCALS~1\\Temp\\ink_ext_XXXXXX.svgVNX14T', '--id=rect2363 ', '--tab=sampling', '--xstart=-50', '--xend=20', '--times2pi=true', '--ybottom=-11.600000381469727', '--ytop=24.600000381469727', '--samples =180', '--isoscale=false', '--polar=false', '--funcplotuse=', '--pythonfunctions=', '--fofx=sin(-x)', '--fponum=true', '--fpofx=x', '--remove =true', '--drawaxis=false'] There must be some stray quotes somewhere. I also wonder why the temporary file is no longer the final argument to the script. I think this could screw up scripts with more primitive option parsing. It looks like the revision that I compiled here includes the .svg extension on the temp files. I never noticed that change. And lastly, can anyone tell me why "sampling" is quoted when it is passed to the script? I thought we had done something to address that. Aaron Spike

Function Plotter
by unknown＠example.com 15 Jan '08

Not sure if this is relevant, but the Function Plotter uses a tabbed display, a "notebook" parameter, which could be causing a problem. I have yet to see a successful implementation of a "notebook" parameter Just submitted a bug on this about 30 seconds ago, Bug # https://bugs.launchpad.net/inkscape/+bug/183030 Alvin Penner ------[ This message was sent using Vaxxine Webmail ]------ www.vaxxine.com - Niagara's Premier Internet Service Provider
