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

How to change notification settings in Launchpad?
by Maximilian Albert 26 Feb '08

26 Feb '08

Hi all, sorry if this is a dumb question but how can I change my Launchpad settings so that I do not receive an email each time someone works on one of the bugs? Is this the default behaviour for members of the "Inkscape Bug Team" group? Currently I am sent a notification for each and every change, but I'd prefer not to get my inbox flooded and rather browse the list myself when appropriate. It may be just my infamiliarity with Lauchpad (and lack of time for detailed investigation), but I wasn't able to find out how turn this off. Thanks in advance. Max

New win32 lib bundle with Dwarf2
by Bob Jamison 26 Feb '08

26 Feb '08

Hi, all, I just uploaded a new lib bundle on the server. It has been over a year since I last updated the C++ libs. I also have wanted for months to move from the existing setjump/longjump (sjlj) exception handling to the new (to MinGW) Dwarf2 EH. Gcc has had Dwarf2 for years, but only recently has MinGW started providing it. It should allow better backtraces and slightly smaller binaries. I made a build with it manually this morning: http://inkscape.modevia.com/win32/Inkscape-0710221807-dw2.7z I assembled some MinGW binaries to make this working compiler: http://inkscape.modevia.com/win32libs/mingw-4.2.1-071022-dw2.7z ...and here is the new bundle. http://inkscape.modevia.com/win32libs/gtk210-071022-dw2.7z Note that the C++ compiler, library bundle, and Inkscape build must all be either sjlj or Dwarf2. You can't mix them, else there will be a linking error. I also added a version of build.xml to the trunk to handle this, build-dw2.xml. This should keep from breaking everyone else's build. To use it: ./btool -f build-dw2.xml Of course there is a corresponding cross-compiler: http://inkscape.modevia.com/win32libs/xmingw-4.2.1-dw2.tar.bz2 ...which made this build, which looks ok, but I haven't run yet: http://inkscape.modevia.com/win32/Inkscape0710230156.7z It looks larger, but none of the DLLs have been stripped yet. From now on, all of the "autobuilds" there will be Dwarf2. Probably in a couple of weeks when everyone catches up, it will become the default. Have fun! ishmal(bob)

raster effects
by Alexandre Prokoudine 14 Feb '08

14 Feb '08

Hi, Here are several more notes on current implementation of raster effects. 1. Terminology and hints. In some cases terminology used in effects coming from ImageMagick is not quite obvious. For instance, you might want to reread a course on math to understand what "Sigma" stands for in "Sharpen"/"Unsharp Mask" effects ;-) We might either rename some of the labels (not good for experienced ImageMagick users) or provide hints to explain the meaning of each option. 2. Raster effects are not the only ones to suffer from it, but here goes: effect dialogs inherit caption from menu item name. In several cases the caption is too long and is shrinked. This is not quite visually appealing. Two solutions comes to mind: 1) automatically resize dialog to match caption's length and 2) provide a separate string to dialog's caption which translators could try to make smaller. 3. Cancelling isn't working reliably. I run "Reduce noise" on a 2200x1500 picture and when I click "Cancel" nothing really happens. 4.Should we probbaly implement a "Resize" effect too? Alexandre

I use Gentoo, so my poppler should be "my own" build. Same with Jeff. (Had you figured this out yet, Jeff?) Is it maybe that some switch needs to be passed to poppler when building it? JF

new libraries bundle for windows requested
by bulia byak 28 Jan '08

28 Jan '08

Hi Bob, Here's a summary of recently discovered problems that this new bundle must address: - it must have that gspawn-win32-helper*.exe thing without which effects now crash - it must have at least gtk 2.10.12, because of this bugfix: 392015 Selected menu item invisible on Windows Vista - it must have libgc compiled with LARGE_CONFIG defined, as per the instructions linked from this bug (in mental's comment): https://sourceforge.net/tracker/index.php?func=detail&aid=1803613&group_id=… to remove the 0.5 Gb memory limit. Thanks, and let me know if I forgot something! -- bulia byak Inkscape. Draw Freely. http://www.inkscape.org

Undo looses selection (in Tweak tool)
by jiho 21 Jan '08

21 Jan '08

Hello again, One other glitch which the tweak tool revealed: undoing looses selection. Example: draw a circle, switch to tweak, tweak, CTRL-Z, tweak again = you can't because the circle is not selected anymore. and furthermore: draw a circle, draw another, select all, switch to tweak, tweak circle nb 1, CTRL-Z, switch to select = only circle nb 2 is selected In fact this happens in all tools: draw a circle [-> it is selected], draw another [-> the second one gets selected], CTRL-Z = nothing is selected anymore This is not particularly annoying in all other tools but it is in the tweak tool, because undoing the first tweak deselects and an additional tool switch is necessary before one can tweak again. I already noticed that when the too was in its embryonic stage in the calligraphy tool... but failed to report it :( It would be nice if: - the selection could be kept in Undo history. this would solve the issue for all tools and in addition I found myself bitten by the lack of selection history several times. Ex: you try to select several small objects, it takes a while, you add another object by mistake, the only way to subtract it from the selection is to click on it again... which cool get messy if there are already several other objects selected, or if you added it via a select under or in group or... - there was a way to select objects directly from the tweak tool. this would, in addition, allow to avoid constant switches between the select tool and the tweak tool (not that s and and w are far apart on the keyboard but still). ALT is not already used as a modifier in the Tweak tool ;) Of course the selection behavior won't be as powerful as the select tool (since the select tool modifiers is already very complex and its modifiers are all full) but just ALT+click/drag = selects and SHIFT+ALT+click/drag = adds to selection would be nice.
