/potrace cleanup
by Bob Jamison 29 Sep '04

29 Sep '04

The /src/potrace directory needed some cleaning up. Also, as Bulia suggested, I needed make /trace a subdir of /src, so that in the future other implementations might be added (such as maybe something of our own). In addition, it is probably best to not litter Peter's Potrace source files with files of our own. So now it is organized as /src/trace and /src/trace/potrace, and Makefile_insert Makefile.am verbs.cpp dialogs/tracedialog.h dialogs/tracedialog.cpp and several of the items in /trace have been edited to reflect this structure. You will need 'cvs up -P -d' to get this stuff. . -Please- let me know if this breaks the build. I am trying a fresh checkout/build to make sure it is OK. Bob

500th bug is up for grabs!
by bulia byak 29 Sep '04

29 Sep '04

The next bug to be closed will become the 500th closed bug. Want some fame? Go to the tracker, find something you can fix, fix it, and announce to the world! :) Seriously, we're having a bit too many open bugs currently. I know everyone is busy with their own stuff, but if each developer could close at least a few bugs it would be very nice. Many of them may not even need any coding but only verifying, testing, rejecting etc :)

SWF Export
by Anatoly Podlesnuk 28 Sep '04

28 Sep '04

Can you explain how to install external extension in inkscape? I have binary (for example "spalah"). It can receive SVG file through STDIN or file (for example spalah < /path/file.svg spalah /path/file.svg ) and print it to STDOUT The questions. 1. How can it receive filename (file.swf) from ExportDialog? 2. Binary must save file.swf or print it to STDOUT? 3. Where to place spalah.inkmod and spalah? Can I place it to $HOME/.inkscape? <inkscape-extension> <name>Macromedia Flash Export</name> <id>org.inkscape.input.sk</id> <input> <extension>.swf</extension> <mimetype>application/x-shockwave-flash</mimetype> <filetypename>Macromedia Flash (*.swf)</filetypename> <filetypetooltip>Export to Macromedia Flash</filetypetooltip> </input> <script> <command reldir="extensions">spalah</command> <check reldir="extensions">spalah</check> </script> </inkscape-extension> 4. "<id>org.inkscape.input.sk</id>" what I have to write here?

Static C++ libraries
by Bob Jamison 28 Sep '04

28 Sep '04

I am not sure if this has been agreed upon, but we are going to use static linking for all of our C++ dependencies, right? In other words, for all of the libs: libsigc++ gtkmm glibmm gc(cpp) They are ./configured with --enable-static --disable-shared, so that subsequent 'pkg-config --libs' calls will return the info needed for static linking? We need to remove C++ dependencies from the shoulders of our users, -especially- since different C++ compilers and different versions of the same compiler usually do not mix. A way to check such dependencies would be: 'ldd inkscape' The C++ libs should not be listed. Bob

icons attempt
by Nicu Buculei 28 Sep '04

i have made an attempt to redesign the icons for raise/lower object, see image attached. i think this shapes look more like the similar icons on various other application and will be better understood by users. -- nicu

idea: "temporary ungroup"
by MenTaLguY 28 Sep '04

28 Sep '04

Talking with a friend today, we came up with the idea of renaming the "Edit group" feature to "temporary ungroup", since that is closer to what it does (from the visual user's perspective). "Edit parent" would then become "regroup". He also noted that Flash lets you do something comparable by double-clicking on a group. That seems like maybe a good idea here too. Thoughts? -mental

"Canny edge detection" - meaning "clever" or "cautious"?
by Colin Marquardt 27 Sep '04

27 Sep '04

Hi, while updating the de.po, I wondered whether "Canny edge detection" means "Cautious edge detection" or "Clever edge detection"? Maybe a different word should be used unless it's totally unambiguous for native English speakers. Cheers, Colin

Re: [Inkscape-user] units

[ user units (before any transformation) = pixels ] If you try to use "real world" units within a viewBoxed document, they will be distorted by the viewBox depending on the particular UA's notion of the current resolution. Conceivably, you could just avoid using a viewBox and user units altogether, except for one thing -- SVG paths can only be specified in user units. Without a viewBox, of course, the real world -> user unit relationship will still vary depending on the resolution. So that won't work either. In summary: everything but user and relative units (relative units being percent, em, and ex) are useless in SVG, except for the purpose of setting document size. In practice, the only way to do "real world units" in SVG is to set the document dimensions in some absolute real world unit, establish a viewBox, and then use nothing but user and relative units in the document proper. -mental

Re: Minor upgrade to autotracing
by Peter Selinger 25 Sep '04

25 Sep '04

Hi guys, I heard from Bob today that he had integrated my "potrace" into inkscape. That is really great! I checked out the inkscape-devel archives and I noticed that Bob was tinkering with brightness settings to prepare an image for black-and-white tracing. Did you look at the "mkbitmap" program, which comes with the potrace distribution? It is a pretty good pre-processor for potrace for certain types of images, like cartoons or photographs of handwriting. For some examples, see http://potrace.sourceforge.net/mkbitmap.html It does not do too great for Bob's venus example, I have to say. The problem (which is shared by the "canny" edge detector) seems to be that both programs look only at edges in the contrast data, and ignores edges in the hue and saturation. Therefore, there are lots of missing edges in the left part of the image. -- Peter
