I just changed the gzip input stream to remove some of it's limitations. Please give it a shake-down and see if it holds up. (It works on assorted-tiling.svgz now)

Adding CxxTest
by unknown＠example.com 18 Feb '05

18 Feb '05

I just did an initial checkin to add CxxTest. http://cxxtest.sourceforge.net Once you do an update, just run "make check" from the top level and you should get src/libnr/testrunnr built and executed along with all the other tests. Or to get just that one, change to inkscape/src and then run "make libnr/testrunnr" to build it. It runs CxxTest to create the needed .cpp from *-test.h files, then builds it.

----- Forwarded message from Jon Ferraiolo <jon.ferraiolo@...720...> ----- Date: Fri, 18 Feb 2005 09:51:22 -0800 From: Jon Ferraiolo <jon.ferraiolo@...720...> Reply-To: Jon Ferraiolo <jon.ferraiolo@...720...> Subject: Re: COMMENT: Flow Text To: Thomas DeWeese <Thomas.DeWeese@...721...>, www-svg@...157... Thomas, Thanks for the great comments! The SVG Working Group has given me the assignment of responding to one of our comments below. You said: >4.14.2 The progression-align property > > Doesn't it make a _lot_ more sense to have this property >apply to the flow regions? What does it mean to have a center >aligned flowPara bracketed by two un-aligned flowPara elements? > > Also I think a description of how this is applied to content >is in order. I can think of several "reasonable" interpretations >which given 'odd' flow geometry could result in widely variable >results. The SVG WG believes the SVG 1.2 LC specification incorrectly defined a 'progression-align' property when instead it is better to reuse the 'display-align' property from XSL-FO (defined within http://www.w3.org/TR/xsl/slice7.html#area-alignment) , which delivers exactly what is needed. The next public draft of SVG will include the 'display-align' property instead. We agree that the 'display-align' property should apply to regions and not to flow content elements. The next public draft of SVG will say that 'display-align' applies to the text container object and not to elements that are part of the text flow such as <flowPara>. In terms of the last paragraph about odd flow geometries and widely variable results, I believe this issue only applies to non-rectangular regions. At the moment, the SVG WG is first addressing SVG Tiny 1.2 requirements (which only supports rectangular text regions) and is adopting the general policy proposed by others that flowing text layout must allow UA-specific layout algorithms to be deployed so that UA's are not prevented from delivering the best possible results. Although we haven't resolved your last paragraph completely yet, there is a possibility that we will allow layout variability in the general case (per the feedback of others), which might lead us to conclude that it is sufficient to simply provide layout guidelines for flowing text in arbitrary shapes (preserving the great technical work by the incredibly bright people who documented the existing algorithms - do you remember who contributed to that work?) but not *mandate* every possible detail for how layout is performed.

Hi, I've been trying to render the exported pov files from simple svg images but I keep getting errors. I'm using povray 3.6 to render the attached pov file, generated from the attached svg file. I'm also attaching the output ;-) Thanks for your help, -- Lucas Vieites Fariña Dept. Desarrollo <lucas@...212...> Asix Informática <http://www.asixinformatica.com/> Tel/Fax: +34 986 54 26 98

resource leaks on Windows
by bulia byak 18 Feb '05

18 Feb '05

Today we have found and patched a number of GDI resource leaks. This will likely fix the bug where using text tool eventually caused Inkscape to freeze with endless "SaveDC failed" and "RestoreDC failed" messages streaming to the console: http://sourceforge.net/tracker/index.php?func=detail&aid=1070816&group_id=9… Everyone who has ever experienced it (and everyone else using Windows), please test a CVS build dated later than today and report your results.

Setting physical resolution and exporting documents
by unknown＠example.com 17 Feb '05

17 Feb '05

Hello! I would like to set the physical resolution of a document to export it as an EPS file at a given resolution. However, I have not found setting of the resolution anywhere in the program. In the "print" menu there is a physical resolution option for the printed images, but it did not work for the EPS files. Another problem is exporting of the documents. It is possible by renaming the file by "save as", and so to export a document without changing its name a double rename is needed, what might be error prone. Thanks, Artur Rataj

Inkscape status 2005-02-15
by Bryce Harrington 16 Feb '05

16 Feb '05

Project Status Tuesday, Feb 15, 2005 Today at work after our all-hands meeting, one of the marketing guys named Carl grabbed me. He'd just upgraded to SuSE 9.2 but knew that we'd just released 0.41, and SuSE only had 0.39. We downloaded and installed the Autopackage version. I gave him a quick tour of the new features. When we got to the color trace function he slapped me on the shoulder, "My god, that's _exactly_ what I've needed!!" He loaded up one of the OSDL member logos and vectorized it with the color trace tool. We get these logos in every format known to mankind, and scaling them can be a real challenge sometimes. This week I've been showing off all sorts of things to people... The new inkscape.deviantart.com. I showed daj's "Rockin' in the Free World" to a professional musician. ScislaC's 'Gaze' astounds _everyone_ who sees it; this is without a doubt the most advanced piece of art ever done with Inkscape/Sodipodi/Gill (we have *got* to encourage Scislac to teach us all the tricks for how he was able to *do* that!) I also of course have to brag about the KDE 3.4 SVG Wallpaper contest, and that of the top 4, half are known to have been done with Inkscape (including the winner). The thing I point out to people at work is that despite how great Linux is technically, there are many, many people who "judge a book by its cover" and consider only how the thing looks. Like buying a car based on its paint job and leather upholstry instead of its engine. But graphical tools like Inkscape are enabling artists to give Linux that beauty, to make it visually as well as technically attractive. In the stats below, the most obvious thing is the sudden jump in linecount. No surprise there - this is all the new code such as gtkmm that finally got greenlighted to go into the codebase. Hopefully over the next few months we'll see the linecount reduced as this new code replaces the gobs of repetitive old code currently in there. The mailing list numbers show that we've gained a number of new members. (Welcome aboard!) Of course, anyone on Jabber or IRC recently will have already noticed the nice jump in activity, both with usage questions and with development work. Things seem to be going quite well!
