The first thing worth noting is that in galicia.svg (which works) the overall size is provided in unit-less values: width="999.000000" height="666.000000" which, according to the SVG specification means that these values determine the size in "pixels" (i.e., a px unit as defined by CSS2). Meanwhile, in cornwall.svg (which fails), the overall size is specified with real-world units (in this case, millimeters): width="234mm" height="140mm" So, converting those real-world units to pixels requires information about the real-world dimension of a pixel. In libsvg there's definitely a bug that there's no way to set that value, (instead it always assumes 100 pixels per inch). But that's not what's causing the strange behavior you're seeing. In cornwall.svg, after specifying the size as 234x140mm the first thing drawn is the "background" rectangle which has a size specified as: width="829.133850" height="496.062988" These values don't have real-world units, so according to the SVG specification[*] they should be interpreted as pixels. And ~ 829x496 pixels is only equivalent to 234x140mm if the pixels are sized such that there are 90 pixels per inch, (which must be the assumed pixels-per-inch value of the tool used to create this file). Therefore, the overall size of the SVG file changes depending on the pixels-per-inch value, but the actual drawing contents do not. And this is exactly the behavior you're seeing with libsvg-cairo. My recommendation for you is to just alter the top-level width and height attributes to use the same units as the rest of the drawing. That is, use: width="829" height="496" This eliminates the 90 pixels per inch assumption from the file, and also happens to avoid the need for a set_dpi function in libsvg. It would still be nice to have something like svg_set_dpi but it wouldn't be an adequate solution for this file. It would allow correct rendering at 90 DPI but not at any other value. Does that make sense? Is there anything else I'm missing here? -Carl [*] http://www.w3.org/TR/2003/REC-SVG11-20030114/coords.html ----- End forwarded message -----

Google Summer of Code proposals
by Bryce Harrington 24 Jun '05

24 Jun '05

Hi all, Today was the final day for the mentors to give input for the Google Summer of Code projects. Google is funding 400 projects this summer, including four projects for Inkscape. The decision for how many slots to give each project was based on the proportion of submissions sent in for each project. Approximately 50 people submitted proposals for Inkscape. There were over 10,000 proposals submitted in total, for 40 projects. Google will be making the final decision of which projects will be selected, based on our prioritizations. The prioritization was extremely difficult (I wish we could have had 8 or 10 projects), but thanks to the work of the reviewers I think Inkscape will gain four very significant new features over the summer.

Re: [Inkscape-devel] google SOC

Yeah, I have that set to "1". Its really a strange bug in my GTK... the same thing happens with Python plugins in Dia. Anyway, I fixed the working dir prob with the glade file, made it return the original document when closed without clipart selection, made it write the raw clipart to stdout when invoked from the command line, and made it parse the svg to find the title metadata, and display that along with the preview image. The expense of grabbing this stuff (the png preview and actual svg) from the server is definitely starting to show, so implementing caching is next on the agenda. The new version is at http://download.berlios.de/termite/ocal.zip (I'm working on a windows box today, so its a zip this time- sorry). Again, let me know if it doesn't work... I still can't fully test it (because of the GTK prob I mentioned).

CxxTest
by Ted Gould 23 Jun '05

23 Jun '05

Last night I was trying to get 'distcheck' to pass and it is have troubles with the testing. This seems to be related to the cxxtest stuff. The cxxtest directory in the CVS tree is not included in the distribution. Should it be? Should I have cxxtest installed on my machine? I tried just including a bunch of the cxxtest files in the distribution but that didn't help. Thanks, Ted

flowText: skewed
by unknown＠example.com 22 Jun '05

22 Jun '05

I tried to submit a bug report but sourceforge wasn't cooperating. If I create a shape like a triangle from three straight lines and then flow a word of text into it. When I skew the triangle properly the text will dissappear. It could just be that the text doesn't fit, but it really looks like it should. Aaron Spike

Post Effect Selections
by unknown＠example.com 21 Jun '05

21 Jun '05

I missed an interesting discussion about which objects should be selected after an effect. I started of the opinion that the previous selection should be restored in order to make affecting the same objects again simpler. But someone suggested that the effect should be able to control the selection. That sounds very interesting. How would this be done? Would an effect insert some sort of attribute (like inkscape:select-me="1") into each object that should be selected? This attribute would be discarded by Inkscape on load. Any other solution would likely pass a list of selected ids. Id collision was one of the first things I wondered about while writing effects. What would happen if I assign a new object an id that is already taken? Inkscape of course fixes it for me. But I have been assigning no id to new objects and letting Inkscape handle the whole thing. This probably isn't a good behavior. And it wouldn't allow for ids to be passed back to Inkscape. What should an effect do to properly handle id assignments? Aaron Spike

Embed Raster
by unknown＠example.com 21 Jun '05

21 Jun '05

I was looking at this RFE: http://sourceforge.net/tracker/index.php?func=detail&aid=1224283&group_id=9… And I figured I could whip up a quick INX file to make it work as an effect: <inkscape-extension> <name>Embed Raster Images</name> <id>org.inkscape.filter.embedraster</id> <dependency type="executable" location="extensions">embed_raster_in_svg.pl</dependency> <dependency type="executable" location="path">perl</dependency> <effect> <object-type>all</object-type> </effect> <script> <command reldir="extensions" interpreter="perl">embed_raster_in_svg.pl</command> </script> </inkscape-extension> But the embed_raster_in_svg.pl script dies at line 110. My entire knowledge of perl comes from two weeks of playing with it for a project last year. And I am thoroughly confused by the Lord Of The Rings humor embedded in the file. Are there any perl hackers willing to help me make this work? Aaron Spike

Odd issue with copy-cut-paste.
by linux peach 20 Jun '05

20 Jun '05

Hi! I just spoke with bryce on IRC and he told me to go ahead and email the list. I have an issue in inkscape that only happens when I choose an object, copy, cut, and then paste that object back into the same file. Whenever I perform these tasks in a row, the object that I have just pasted disappears in any preview or use mode, such as in nautilus, gimp, gnome-panel, gnome icon themes, etc. but whenever I look at the file in inkscape, the object is still there. I can edit the object, distort it, reshape it, etc. and as long as I do not cut-copy-paste, the object remains visible. And nothing I do after the copy-cut-paste makes the object visible again. I have reviewed the xml files and I cannot see a difference that would make the object invisible. I have included two sample files: the original gnome-fs-directory.svg file, and then the modified gnome-fs-directory-issue.svg file that has a major object that has been copied-cut-pasted, that no longer appears visible. I can repeat this issue on any file with the same results. I've scoured google looking for any hints, and the only thing I could find was regarding Nautilus 2.1.5, and I'm on 2.10.0. Is there anything I can do to repair the object to make it visible again?

xml:space namespace error
by unknown＠example.com 20 Jun '05

20 Jun '05

The attribute xml:space="preserve" as found on Inkscape's flowDiv causes an XML Namespace Error when being parsed by PyXML's SAX2 reader. Any of my python effects should display this error. Is this our problem or PyXML's? Aaron Spike
