LPE plugin framework
by unknown＠example.com 01 Feb '08

01 Feb '08

Hi all, I'd like to start working on building a *plugin* framework for the LPEs (for example, but maybe tools too? dunno, let's try with LPE 1st). My motivation is two-fold: 1. I'd like people to be able to create new LPEs without requiring a new Inkscape release, like the current python extensions 2. it seems a challenging task! :) I'd like to hear opinions, tips, critique, everything about this from you. Dr Dobb's has very recently published articles about building such a framework which I am intending to follow (haven't read any of it, except the title). Again what do you think of this? Regards, Johan

Considering the set that you're missing you probably only need to install something like "gtkmm-2.4-dev" or "gtkmm-2.4-devel". It's not a bug, it's a very apt warning :) > Any chance of someone producing a F8 rpm? The previous Fedora packager left the project, I'm unsure if someone from the Fedora project has decided to replace him. I hope so. --Ted

Inkscape 0.46 pre 1 tarball created
by Ted Gould 01 Feb '08

Howdy Inkscapers! While we're not quite to the point of a release, we're getting close enough to see the second pre-release of the much-awaited 0.46 release of Inkscape. The files can be found here: http://sourceforge.net/project/showfiles.php?group_id=93438&package_id=9911… With these MD5 sums: 2b3b31cb92c558a68534f190d31b0d72 inkscape-0.45.1+0.46pre1.tar.bz2 90c77e005d0e3d845f0c196e7843a6da inkscape-0.45.1+0.46pre1.tar.bz2.sig 83c8653d3ca4d9cd46e730d9adf8c669 inkscape-0.45.1+0.46pre1.tar.gz e4f7f4b9ef24925cee7a8964e7e671e6 inkscape-0.45.1+0.46pre1.tar.gz.sig cff35c0f01671837f33f4bc19675decd inkscape-0.45.1+0.46pre1.zip 7b55ec81c1824f503fc4c8b6acb90f9f inkscape-0.45.1+0.46pre1.zip.sig Packages will hopefully start appearing shortly. --Ted

Updating the win32 library bundle
by Bob Jamison 01 Feb '08

01 Feb '08

Hi, all, Several people have been asking me to make additions and changes to the library bundle before the release. Since there are so many, I would like to try it incrementally rather than everything at once. This would make it easier to pinpoint a problem. So first I've added Cairo 1.5.6 and Poppler 0.6.4. Here is the lib bundle: http://inkscape.modevia.com/win32libs/devlibs-2.12-080131.7z and a "full debug" build made with it is here: http://inkscape.modevia.com/win32/Inkscape0801311945-fulldbg.7z and a regular build: http://inkscape.modevia.com/win32/Inkscape0801312227.7z People who have had problems with PDF import recently might want to try these. Gtk 2.12 and the "C++ exceptions not crossing DLL boundaries" thing are next, I guess. And probably that libxml2 security fix, too (bug in parsing unicode escapes). bob

The interaction between anti-aliasing, transparency, and gamma-correction
by Lambisgoia 01 Feb '08

01 Feb '08

Hi All, This is my first post to this list, so I will keep things brief. First of all, I love Inkscape, and this is the reason for the message. My tests indicate that, when rendering, Inkscape implements anti-aliasing and transparency directly in a gamma-corrected color-space. Am I right? It is my opinion that these operations should instead be performed in a linear color-space. Although it is now probably too late to change the default behavior of transparency (given that the artists used gamma-corrected blends as reference while creating their content), it is not too late to modify the behavior of anti-aliasing. Also, perhaps a tag could be used on future files to identify that they were created under the assumption of linear-blends. Jim Blinn has a very good article on the subject: Jim Blinn, 2003 "A Ghost in a Snow Storm", Jim Blinn's Corner: Notation, Notation, Notation, Chapter 9, pages 133--146, Morgan Kaufmann There, he explains the problems that arise from performing blends in a non-linear space, in better words than I ever could. At any rate, I'd be happy to give examples and to elaborate on the topic once I receive a message that reassures me I am posting on the correct alias. Kind regards and thank you for such a great tool, Diego

Fwd: Stupid question - object's dimensions
by Rob Antonishen 01 Feb '08

01 Feb '08

Is this using a python extension to inkscape, or in an external application? If an extension, you can call another instance of inkscape passing the --query-all parameter and get a list of all the bounding boxes for every object in the svg file. -Rob A> On Jan 31, 2008 12:37 AM, M.

Accessing Resource Data in Python Scripts
by Joel Holdsworth 31 Jan '08

31 Jan '08

Hi All, I'm just working on a rendering extension, which needs to access a collection of source data files. Really I'd like to add a sub-directory to the extension scripts directory, but I'm having difficulty accessing the sub-directory, because when my script starts, it's working directory seems to be my home directory not the extension directory. So if I call the line inkex.etree.parse( "my-sub-dir/data.svg" ) it only returns successfully if my-sub-dir is in my home directory. Does anyone have any suggestions how to access my data files from their installation directory? Thanks Joel
