Translatable SVG document support
by Andrius Ramanauskas 08 Apr '06

08 Apr '06

Hi, I am currently planning to add support for internationalized (translatable) SVG documents. And I guess it is better to share my thoughts before going deep to implementation, so everyone will be aware of my plans and maybe someone will criticize or adjust my plans. My current plan is to implement this in steps: * 1 step - <switch> support. I already tested prototype of semi-working switch element support, but there still some work to do. Currently switch element works just like <g>, but I will make it work according to SVG standard - to render only first element which conditional properties evaluate to true (I will implement support for "systemLanguage" property for a start, which will evaluate to true if property is not set or contains current document language). I plan to make SPSwitch a subclass of SPGroup, so user can enter switch element (turn it into a temporery layer, which will show all contained items, not just first) * 2 step - bitmap export by language (ability to define language to use for <switch> in command line) * 3 step - export/import of texts. Import will also create <switch> elements if not already created * 4 step - UI support for language. I don't know for sure how it should be implemented, but I guess there should be a menu item to turn text to switch ("Make translatable") and language combo in Text dialog (to be shown only if switch is selected) Anyway, I'm open for there are any suggestions or objections.

Markup in verbs.cpp
by Jon A. Cruz 08 Apr '06

08 Apr '06

I just noticed a problem in verbs.cpp The tooltips in the toolbar show raw escapes instead of the character being represented. That is... I see "Rotate selection 90° clockwise" instead of "Rotate selection 90º clockwise" I noticed that one went in on a checkin for fixing things inside of menus. That seems to work for me. However, it appears to be at the expense of the tooltips. Since GTK+ is all UTF-8 based, I tried changing it to escaped literal UTF-8 values. "Rotate selection 90\xC2\xB0 clockwise" now makes it work in both locations for me. Sooooo..... does anyone else see the problem? And/or does anyone know of a better correction for it?

Announcing InkscapeSVG
by unknown＠example.com 07 Apr '06

07 Apr '06

Greetings fellow Inkscapers, This announcement is a couple of days late due to problems establishing our new project web site.... but as the say, better late than never. Much hard work has gone into developing Inkscape, the world's best free vector drawing program. But times are a-changing. The world is being Googled. Applications must be web based. We, who firmly believe in the open SVG standard, must move on too. Thus it gives us great pleasure to announce that our future efforts will be towards creating InkscapeSVG, a web based vector drawing program written in... ta-daa... SVG itself! Already a prototype exists including several basic shape tools and a swatches pallete. You can check out development at: http://inkscapesvg.free.fr Make sure you check out the nifty text tool too! Sincerely, Your InkscapeSVG team.

Large checkin for sizes
by Jon A. Cruz 07 Apr '06

07 Apr '06

I just did a checkin of 22 files to start cleaning up the icon size issue. Although there were many files touched, the actual line count is fairly low. The main thing is to switch off of use of the GtkIconSize enum. For end programmers out there, the change is only from "GtkIconSize" to "Inkscape::IconSize" and from "GTK_ICON_SIZE..." to "Inkscape::ICON_SIZE...". Thus it should be a very low-impact one. So please give things the once-over to make sure nothing snuck in as far as side-effects go (it did pass 'make check' and all the other smoke tests I ran, but it's always good to check). The thing this checkin should have achieved is isolating use of GtkIconSize to just two main files. That way the work to change some icons smaller can go in easily. For those who care about details... The calls for themeable stock items use GtkIconSize as a base, but then allow for arbitrary string-based sizes to be registered for new int values. Thus we can't simply extend their enum with +1 and use that directly. Instead we need to add in a lookup to translate at run- time from our extended enum to the types registered dynamically. This buys us quite a lot of functionality, and only needs extra work in a single file. First phase was to encapsulate the use of GtkIconSize in those two main locations. The second phase is to add the dynamic mapping of enum/int values. Then the third stage will be to change selected things (like the eye and the lock) to use Inkscape::ICON_SIZE_DECORATION.

Windows XP: Interface very slow
by Michael Gorbach 07 Apr '06

07 Apr '06

I am trying to use inkscape on winxp pro sp2 and the program does not run well at all. The drawing of widgets by gtk is very slow. I can see black rectangles appearing where the menu should be before the menu is drawn. Is this a known issue of some kind? Is there a fix? Michael Gorbach

Do a CVS visualization study, GET CASH
by Eric Gilbert 07 Apr '06

07 Apr '06

Hi, I am a graduate student at the University of Illinois at Urbana- Champaign. I am doing a study soon on the effects of CVS and mail visualization on open source communities. Check out my work here: http://social.cs.uiuc.edu/people/gilbert/research.html (info on the projects) http://social.cs.uiuc.edu/people/gilbert (info on me) If you are a developer, I could use your help. Look at the visualization, do some surveys and we give you a $20 gift certificate to newegg.com. I am not ready quite yet; still waiting on IRB approval (http:// www.irb.uiuc.edu/). Please keep us in mind if you are interested... I will ask again soon, and then that's all the spam. Contact me if you want more information now. Thanks, Eric -- "Tyranny is tyranny, let it come from whom it may." -- Revolutionary conscripts, 1776

svn 11251 dumps core
by inkbottle 07 Apr '06

07 Apr '06

Here is a reproducible crash on svn revision 11251. My 12-year old found this crash running .43 on FC4. I reproduced the problem on FC5 at the tip of svn, rebuilt inkscape debug and produced a stack trace from the core file. The crash is caused reliably in the following way. Enter some text. Zoom in on the text, or make it big enough to work with easily. The text I used was "This is some text". Select the text tool. use that tool to select,say, the initial T. Change the size of the text to something else noticeably different, it doesn't matter what. The T changes size appropriately. Then place a gradient on the text string as a whole. Now select, say, the s in 'some' with the text tool. Change the size of that s to any other size. Poof! inkscape dumps core, and vanishes. Here is the gdb backtrace. It is a bit beyond me at the moment. This has something to do with text, gradients and, from the backtrace, selection and styles. I'm hoping someone can make more sense of the backtrace than I.

Clipping and masking bugs
by Tavmjong Bah 06 Apr '06

06 Apr '06

Hi, I've begun to update my book for 0.44. Should be a great release! But, I have run into a few bugs with a version of Inkscape from SVN a day or two ago. The following file can be used to illustrate the problems: http://tavmjong.free.fr/INKSCAPE/DRAWINGS/ClipMask2.svg The raw objects for clipping and masking are on the left, the clipped and masked objects (blue rectangles) are on the right. In the case of the first two items, the file is displayed correctly in Firefox trunk. 1. Clipping using stroked text without fill doesn't seem to work. 2. The masked object is invisible when the file is saved and reopened. The masked object can be restored by selecting the object, unmasking and remasking. 3. Sometimes the display of the gradient is not updated when the gradient tool is used to adjust it. Try editing the gradient in the above document by dragging a gradient node. 4. Not really a bug... but very confusing. The gradient editor does not switch to the gradient selected with the the gradient tool. This behavior is different from all other dialogs. If needed, I'll file bug reports but I thought I would bring them up here first. Tav

IO::Resource vs. Binreloc
by Aaron Spike 06 Apr '06

06 Apr '06

I was going to build an autopackage this morning for those who would like to play with the new keymaps but the build errored out with the following message. I'm assuming that it is caused by Binreloc because that is something that is different in the autopackage build. I understand some of the words but it is still a little beyond me. mental?
