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

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

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.

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

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?

GUI For Insckape Script Extensions
by Redefined Horizons 05 Oct '07

05 Oct '07

I noticed the attached slide on Ted's presentation on Inkscape extensions. In the python example available online I see how to use the automatic GUI for scripts to collect text or String data. Can someone point out some examples or documentation that explains how to set up an automatic GUI for a script that uses enumerations or radio buttons? Would it be possible to use PyGTK from within an Inkscape extension script? Thanks for the help. Scott Huey

Composite Filter, arithmetic mode
by Tavmjong Bah 04 Oct '07

04 Oct '07

Hi, I've been studying the filter primitives. While the work that has been done is quite impressive, there seems to be quite a bit of polishing to do. I am currently having trouble with the Composite filter primitive. As I read the standard, the K values in the Arithmetic mode can be negative. This leads to the case where one or more of the calculated RGBA values can be negative. Of course these must eventually be clamped at zero. However, the calculation is done by using integers with the K values multiplied by a power of 255. The resulting integer is then normalized to be between 0 and 255 by the NR_NORMALIZE_31 function located in nr-pixops.h. This function uses the FAST_DIV_ROUND routine (also in nr-pixops.h) which is only valid for non-negative numbers.... thus it gives the wrong result (a positive value instead of zero). Can an expert suggest a fix? Tav

Re: [Inkscape-devel] Color Tweak - Option to not create new gradient
by rosros-3＠...112... 04 Oct '07

04 Oct '07

Xara's designers think that "named colors" is a great feature of their program and I agree with them. Changing the color of 100 objects without affecting 100 other objects that have the same current color on the canvas can be achieved easily with named colors (complicated selections may be needed otherwise). With two-stop gradients one must edit two stoppoints, with one-stop gradients just one ... of course. Linked gradients (and colors), that is unforked ones, can save SVG code and improve loading (and perhaps rendering) speed. Moreover, this feature is already there! So, why removing it? It just needs to be made more perspicuous ... and perhaps enhanced with "shades" of the same color, another great feature of Xara, for which the code in Inkscape is already there according to Jon Cruz!! Shouldn't Inkscape be made SVG-1.1-compliant (see the opensource Batik 1.7 [http://xmlgraphics.apache.org/batik/], which - for instance - renders SVG 1.1 feColorMatrix very well; try opening http://sourceforge.net/tracker/download.php?group_id=93438&atid=604306&file… in Inkscape)? rosros -- Email.it, the professional e-mail, gratis per te: http://www.email.it/f Sponsor: Scegli ciò che stai cercando tra migliaia di annunci, prova con Email.it Annunci, linserzione è gratuita!

CMS display adjustment change
by Jon A. Cruz 04 Oct '07

04 Oct '07

Hi, I just checked in an update with icc color profiles and setting display calibration. Now upon startup latest SVN Inkscape will search the standard locations for profiles ~/.color/icc /usr/local/share/color/icc /usr/share/color/icc Then under the misc preferences you'll have a checkbox for enabling display calibration, along with a drop-down combo box that allows you to pick between all RGB display profiles found. Give it a rundown and let me know how it's behaving. Thanks.

Getting the ID of the selection in a Python script for Inkscape.
by Redefined Horizons 04 Oct '07

04 Oct '07

I was wondering how to obtain the current selection from within an Inkscape script written in Python. I note that the getselected method in the inkex.py file contains a comment that says it "Collect selected nodes". Does this mean that it only returns the nodes from the selection? Does it return the DOM representation of the selection? What is the quickest way, if it is even possible, to obtain the current selection in Inkscape from a python script? I'm thinking maybe I can get an id of the selection with a helper method an then use some methods in to get the DOM element of the selection using the "id" attribute. I hope my question makes sense. I've been trying to read through some of the material online about writing scripts and/or extensions for Inkscape, but I must admit it is a little confusing for me. I appreciate your patient assistance. I will do my best to post a summary of any responses to this question on the Inkscape wiki if that would help other future script writers. :] Scott Huey

NEW: CDR (CorelDraw) import via UniConvertor
by bulia byak 29 Sep '07

29 Sep '07

Inkscape can use UniConvertor (http://www.sk1project.org/modules.php?name=Products&product=uniconvertor) if it's installed on your system to import documents in CDR format (CorelDraw). This feature is Unix-only at this time (since UniConvertor is Unix-only) and requires that you have Python and UniConvertor installed. As of UniConvertor 1.0rc2, only versions from 7 to X3 of the CDR format are supported, and text objects are not converted. -- bulia byak Inkscape. Draw Freely. http://www.inkscape.org

In other cases the new tool seems to work fine and I wonder why it's not enabled in the toolbox yet ;-) Kudos to Maximilian! Alexandre

I am thinking about an 'Enveloppe' path effect (LPE), something similar to the path-along-path LPE: http://www.inkscape.org/screenshots/gallery/inkscape-0.46-lpe-pathalongpath… You'll need to draw two paths, one for the upper bound (ellipse in your case) and one for the lower bound. You apply the effect to your 'Text > Object to Path' and then your text or path will be stretched from upper bound to lower bound. You'll then be able to edit the bounds live on-canvas, so you can quickly change things around :) I am not sure whether this will make 0.46, probably not unless some other developer is interested in implementing this. I can give a lot of help if someone is interested in making this! Regards, Johan

empty directories
by Alexandre Prokoudine 27 Sep '07

27 Sep '07

Hi, To the best of my knowledge, by default several empty directories are created by Inkscape installations: $PREFIX/share/gradients, fonts and patterns. I've already seen several times people asking, where they can find patterns or gradients for Inkscape, because they think that something is supposed to be put there :) Should we get rid of them until we properly support that functionality? And do we have some kind of vision for patterns/gradients libraries? Alexandre
