docking for extensions
by Alexandre Prokoudine 09 Oct '07

09 Oct '07

Hi, What do you think about docking floating extensions dialogs (i.e. dialogs with "Floating" option enabled)? When you have several of them around and you need them all the time, docking them would make sense. Alexandre

BIg slowdown using Tweak tool -- sp-item.cpp
by John Bintz 09 Oct '07

09 Oct '07

Hi, all. It looks like a change that occurred in rev. 15821 has caused some big performance issues when using the Tweak tool. In sp_item_update, this block of code is called with every update: if (item->display && item->display->arenaitem) { NRRect item_bbox; sp_item_invoke_bbox(item, &item_bbox, NR::identity(), TRUE, SPItem::GEOMETRIC_BBOX); NR::Maybe<NR::Rect> i_bbox = item_bbox; nr_arena_item_set_item_bbox(item->display->arenaitem, i_bbox); } and this is making the Tweak tool very slow to respond. Is there a better way of computing the SVG bounding box for the Arena item on an as-needed basis, rather than with every update? Also, I looked at other places that used item->display and that seems to be a linked list instead of just a single item. Thanks, John

PDF import extension
by Miklós Erdélyi 08 Oct '07

08 Oct '07

Hi, the cairo-based simple PDF import extension has been in trunk for a while (well, for a week or so :) ). Now I have committed a preliminary version of the native libpoppler-based one to trunk (you can activate it by uncommenting the line Internal::PdfInput::init() in src/extension/init.cpp). I did commit this unstable version because I need your help regarding a strange bug. When a PDF document is opened Inkscape crashes with segmentation fault, giving the following backtrace: #0 0xb6ebeb46 in malloc_usable_size () from /lib/tls/i686/cmov/libc.so.6 #1 0xb6ec0ecd in free () from /lib/tls/i686/cmov/libc.so.6 #2 0xb6ec283f in malloc () from /lib/tls/i686/cmov/libc.so.6 #3 0xb70844b7 in operator new () from /usr/lib/libstdc++.so.6 #4 0xb70845ed in operator new[] () from /usr/lib/libstdc++.so.6 #5 0xb71719d2 in PDFDoc::checkFooter (this=0xa6c5700) at PDFDoc.cc:248 #6 0xb7171e90 in PDFDoc::setup (this=0xa6c5700, ownerPassword=0x0, userPassword=0x0) at PDFDoc.cc:185 #7 0xb71721c5 in PDFDoc (this=0xa6c5700, fileNameA=0xa6c56c8, ownerPassword=0x0, userPassword=0x0, guiDataA=0x0) at PDFDoc.cc:102 #8 0x08594ec7 in Inkscape::Extension::Internal::PdfInput::open ( this=0x8857030, mod=0x8861350, uri=0xab497e4 "/home/shudo/tiger.pdf") at extension/internal/pdfinput/pdf-input.cpp:51 Please test whether the same thing happens on your system also (note: PDF import is not yet available on Windows) and tell us if you have any ideas regarding the solution to this problem which sets back the further development of the import extension. Thank you, miklos

Re: [Inkscape-devel] [Inkscape-user] contribute to graphics research!
by bulia byak 08 Oct '07

(forwarding this to devel list as well) This sounds like a very nice addition. We (developers) actually were thinking about adding something like that, as an option. Would you consider adding your patch to the SVN trunk so it becomes part of the official Inkscape releases? For users, persistent undo is an important enough feature by itself, with or without helping your graphics research :) And if you keep working on it to add more features like selective undo, this is much better to do in the main trunk.

Tabbing in Docked Dialogs (0.45+Dev, Sept 6 Release)
by Tony Vigil 07 Oct '07

07 Oct '07

Using the tab key while editing parameters inside docked dialogs in the development version doesn't work as expected. Tabbing still cycles the object selection as though the canvas has focus. This can lead to very unwanted results if you enter data, tab to the next parameter, enter more data, then hit return. Is this tabbing behavior while in the docked dialogs intentional? - Tony

Hi, An issue was raised in #inkscape today about donations. Some people would like to donate money to the project, but 1) We have no PayPal link on main page, and SourceForge page is not obvious enough. 2) Not everyone wnats to register at SF to be able to donate. What shall we do? Alexandre

I find it useful to grep for things I'm looking for in that directory.

You don't need to specify the modules in your INX file. The dependency checking that Inkscape has isn't very smart, it is only the basically looking to see if a file exists in the path or in the extensions directory. It doesn't know about how to load Python modules or anything like that. > Also, what version of the Python interpreter is used by Inkscape?

On Linux, Inkscape will use the python interpreter from your system first. You can overwrite that in your settings if you like. On Windows, it will use the version of Python that is packaged with Inkscape, which I believe is 2.5. > Thanks for all the support guys. This is really great and unexpected! No problem Scott. In the Inkscape project we believe that success is determined by the number and quality of contributions. We want everyone to be able to contribute what they can. --Ted

nodepath.cpp compile failure with gcc3; which isnan.h?
by John Faith 05 Oct '07

05 Oct '07

Hello, I did 'svn up' to version 16183 and hit trouble in nodepath.cpp when building with gcc 3.3 under OS X 10.3.: ... g++ ... nodepath.cpp ... 2geom/linear.h:90: error: `isfinite' undeclared in namespace `std' I noticed that src/2geom/linear.h includes src/2geom/isnan.h, which is a bit different from src/isnan.h. The former does not have gcc3/apple ifdefs. Was isnan.h copied into 2geom at some point, and if it should be the same file, why not just let the include path find the one in src/? By the way, replacing src/2geom/isnan.h with src/isnan.h (which has the ifdef gcc3 stuff) does not fix this. Thanks, John

Little enhancement for font toolbox dropdown
by Daniel Genrich 05 Oct '07

05 Oct '07

Heym some guys on irc forced me to write this on the mailinglist :) I had to test 200 fonts if they fit for my text. Everytime I selected some font from the list, the dropdown menu closed. Quite annoying for me. This little patch prevents automatic closing, enables browsing via arrow-up and arrow-down, and closing of the dropdown menu via return/enter. Already tested by some irc guys :) you'll find the diff against today's svn here: http://pastebin.ca/725982 It's a 4-liner :) Greetings and good work, Daniel

Re: [Inkscape-devel] Color Tweak - Option to not create new gradient
by rosros-3＠...112... 05 Oct '07

05 Oct '07

Things that could be done in a future enhanced gradient editor: 1) Chosing the interpolation between stoppoints (for instance linear, cubic spline, other functions...) [of course this is the abstract viewpoint, since finally all SVG gradients will be a set of stoppoints with linear interpolation of colors and alpha between them]. 2) Inserting formulae for the generation of RGBA values AND of the positions of stoppoints see http://rosros-3.blogspot.com/ 3) ... rosros -- Email.it, the professional e-mail, gratis per te: http://www.email.it/f Sponsor: Vuoi un prestito fino a 30.000 Euro?
