That's a huge topic :) I will cover some basics now, but the best you can do is join our jabber chat and ask your questions there. Most of the time there are people there who will be able to answer your questions, or at least give some useful pointers. > From > what I understand, some callback from the UI should create the SPFilter, No, it's the other way round. SPObjects are created by the XML tree (which we call "repr" tree) of the document. Each element in source SVG creates a repr (branch in the repr tree, an object of the class Inkscape::XML::Node), and each repr creates a corresponding SPObject. A repr stores information in attributes and their values, so it corresponds 1:1 to the source XML, but SPObject may store its information in any convenient way. The correspondence between repr names and SPObject types is in the file sp-object-repr.cpp. Add your new SPFilter object to it, then load an SVG file with a filter, and that should trigger the creation of an SPFilter object upon load. Most of the time information goes downstream from repr to SPObject. Whenever an attribute of a repr changes, its SPObject's set method gets called with the new data. This method should parse this information and store it in SPObject's fields, and if necessary call display update. > which in turn is responsible for updating the respective XML node, everytime > a change is made to the filter. Most of the time it's the repr that updates the SPObject, not vice versa. However the reverse update is also possible: each SPObject has the write method which updates or creates the repr from the SPObject. But this is used mostly during save to plain SVG when all the repr tree needs to be recreated. > I also presume that this XML component is > not of much use for Niko, since he gets the data to display from the > SPFilter.

As I said repr is created automatically, and at first you can do even without a write method in your SPFilter. The set method is much more important. > (or correct) these thoughts, and define some milestones so that I can make > sure I'm developing things on the right order and that Niko always has the > structures he needs from me. The obvious first step is to have SPObjects created for all filter elements and make sure the information is correctly transferred from SVG into the members of these objects. > Could you also clarify the purpose of the 'flags' argument, found in most > SPObjects' functions (what are they used for, should I worry about > them,...). They are used in update propagation, i.e. affect screen display. For now you may ignore them. -- bulia byak Inkscape. Draw Freely. http://www.inkscape.org

Tooltip bug in pre1...
by Spyros Blanas 02 Jun '06

02 Jun '06

Hi, I am testing pre1 on WinXP SP2. Am I the only one to experience problems with escaped HTML characters in the tooltips? (see attached image for an example) Also, I don't know if it is reproducible on Linux systems. Can anyone else reproduce this, so as to file a bug report? - Spyros Blanas

0.44pre2 distcheck
by Aaron Spike 02 Jun '06

02 Jun '06

I get: ../../src/extension/implementation/script.cpp:30:26: error: registrytool.h: No such file or directory Now, rwst has finally beaten it into my head that this message means I need to add something to a Makefile*something*. First question is which one? Am I correct that autogen.sh uses Makefile.am (including Makefile_insert) to generate Makefile.in which is used by configure to create Makefile? So I should add registrytool.* to Makefile_insert. Next question is where in that file should it go? There are a number of different groups of files. I should also ask. registrytool.h was most recently included in src/extension/implementation/script.cpp by ishmal in revision 12129. But it was originally added to the source in rev 10506 with the comment "new files for win32 only". Is this file now being used on other platforms? Thanks in advance for the education. :-) Aaron Spike

Hey guys! I just build inkscape from svn a few hours ago and no notice, that I don't have icons and dialogues. Any idea, what I'm doing wrong, or how to fix it? Thanx! David

NEW: Native PDF export
by bulia byak 02 Jun '06

02 Jun '06

I have committed the patch by Ulf Erikson that adds native PDF export (based on PS export code). It has many limitations but at least it's better than what we have now, because it does not require Ghostscript and, most importantly, handles transparency. Complex illustrations, such as this one: http://www.inkscape.org/screenshots/gallery/inkscape-0.41-CVS-linux-davinci… are shown quite faithfully by Adobe Acrobat after saving as PDF (though much slower than in Inkscape... and I thought our renderer is the slowest, heh). Current limitations include: no text (check "Convert text to path"), no gradient on stroke, no clipping/masking/patterns, no eccentric elliptic gradients, no bitmaps. I know we're probably going to have at least one SoC student working on PDF export, and I think it will make a perfect sense for that student to work on this existing code to improve it. However, even if the student will choose some other approach (e.g. using Cairo), it will be easy to replace this code. For now, however, it's the best we have, and I want this to be in 0.44. -- bulia byak Inkscape. Draw Freely. http://www.inkscape.org

Layer opacity
by Jon A. Cruz 01 Jun '06

01 Jun '06

This got delayed in order to track down and fix the save as ODG crashing bug, but it's in now. Please give it a good workout to make sure it's solid. It's been pending for a bit, but it gives a lot of benefit to end users. There were no main objects in the Jabber room, and even at least one "the main reason I use layers in gimp". It's gotten a good shakedown with GTK+ 2.6.10, so anyone with 2.8.x would be very welcome to finish running it through it's paces. (Oh, and for translators, it did bring in one change of adding "Opacity:" to that dialog)

PyXML missing - bug on 0.44pre1 on WinXP
by Spyros Blanas 01 Jun '06

01 Jun '06

Hi! I was testing 0.44pre1 build for Win32 and spotted that PyXML issues with extensions (when having installed python seperately on windows) have not yet been resolved. I don't know if there is a way to hack around this (ideas: invoking python with full path, changing PATH variable before execution, installing PyXML on user's machine if not available) but at least there should be a more informative message on what is going on. The current message hardly clarifies anything: "The inkex.py module requires PyXML. Please download the latest version from <http://pyxml.sourceforge.net/>." Average-user questions: What is inkex.py? What is a module? What is PyXML? Why is it required? (Let alone the fact that this installer crashes during installation on my machine and required installation via the command-line) Remember, this is a *release* and there will be plenty non-programmers using it. And I think that such an error will prevent many people from enjoying the work done on extensions. - Spyros Blanas

package problems with ./configure
by tj 01 Jun '06

01 Jun '06

How do you configure and by-pass the package stuff. My system seems to have everything neccassary to build inkscape. But, since I built a lot from source and Slackware packages they are not in a .pc file so ./configure fails. So, can is there a configure option that will build the make files and let me take care of any library problems by hand? My libs are in what is considered the "statndard" dirs. /usr/lib, /lib, /usr/X11/lib, etc... tj
