Anyway since I've realised it's only 2.5K, the entire list can now see what a mess it is. All my work was done with version 12 files, but since the UI of CorelDraw hasn't changed fundamentally since version 9 at least (and in fact I can name some bugs that have been around since then too) I'd be surprised if the file format has changed. The large differences you're seeing are almost certainly due to the compression (zlib) which will have the effect of magnifying even a one byte change (eg a creation timestamp). Richard.

Scribus cmdline import/export (patch)
by Bryce Harrington 25 Sep '05

25 Sep '05

Hi Peter and Craig, A while back we discussed an idea of packaging the scribus pdf/ps import/export code for use with Inkscape, since Inkscape's pdf/ps (esp. EPS import) support is so poor. However it occurs to me that another solution would be to simply give scribus some commandline options for doing import/export. E.g. scribus -i filename.eps -e filename.svg Inkscape would then be able to make use of scribus' import/export capabilities via its extension mechanism. Since for all practical intents and purposes, people would need to use scribus for getting eps/pdf converted to svg for use in inkscape already anyway, I don't think this imposes much additional dependency hassle for them. I looked into the scribus code a bit to see how this could be implemented. I wasn't sure how to call the import/export plugins, but I sketched out the code for handling the -i/-e commandline options as a start... See the attached patch. I put TODO's where the code to invoke the import/export plugins would go. I think that if it supported command line options for your input/output operators, scribus would become more widely useful, especially for commercial users (look at http://www.pdftron.com/store.html).

Inkscape 0.43 Hard Freeze
by Bryce Harrington 25 Sep '05

25 Sep '05

With the completion of the bug party today, it is time to move into the hard freeze for Inkscape 0.43, under the watch of our release wardens pjrm and joncruz. Today's testing unfortunately did not cover all of the new features, but we did manage to bang on the connector code really hard, and scared up a number of bugs in it (no showstoppers, but a couple crashes and a lot of odd behaviors.) We attempted to get the inkboard feature working, but did not succeed in establishing a working connection, so there's at least one bug there... We closed about 10 bugs today, mostly invalid/dupe/outdated, but there were a few fixes. pjrm and joncruz will be the release wardens for this release. All changes to the codebase must go through them. Do not commit to CVS; instead post your changes as patches to the tracker with your rationale for why to include them before or after the 0.43 release. Peter and Jon will decide when the codebase is ready for release. This may include requiring specific bugs be fixed, or tasks to be done. When they feel it is ready, the codebase will be tagged and branched, and we will enter the release phase. I will continue to track tasks for the 0.43 release, but it will be up to them whether to wait until all those tasks are complete or to decide we are ready to release with some tasks still unfinished.

Okay, I made a couple changes to the Makefile.PL and moved the .pm's into the lib dir and the script into the scripts/ dir, where they should go. Also I fixed up the authors list (good of you to include all of them!) This package installs ok on my machine. I had installed all my prerequisites like this: # cpan -i Math::Matrix # cpan -i Text::PDF::File # cpan -i PDF::API2 Then I could run pdf2svg. Again though, my results with it were not very good. Probably these issues could be fixed, however it would require knowledge of Perl to do so. I think it may be better to focus on using Scribus for PDF import instead though. What do you think?

Has anyone tried this for producing swf files from svg? http://robla.net/1996/svg2swf/ Looks pretty old, but if it works it might be interesting as a plugin. Bryce

inkscape crashes and freezes gdb when clicking on a square that is rotating
by unknown＠example.com 24 Sep '05

24 Sep '05

Hi in inkscape cvs when I create a square and start rotating it with ] and while it is rotating i click on it, 50% of the time inkscape segfaults. As it does it also freezes my terminal. Because of that I couldn't really make a bug report since I have to switch to ctrl+alt+f1 and kill gdb from it and all my output disappears.

I hope to make time to read the SVG Tiny specification soon but I have a feeling it is also a fairly large task too because it includes some basic animation. It also has the advantage of effectively targeting a very specific commercial market allowing inkscap to potentially dominate a particular niche (with total world domination to follow, mwuhahahah!). > maybe import filters could also be a goal. Thing about import export filters is that they could be done in parallel to other work and are a relatively good way to draw in external developers. File filters a discrete seperable part and are exactly the kind of feature which can be postponed indefinately. The trick is to have a stable enough API to allow external developers to come in and work on filters without needing to worry about keeping up with other other changes in the codebase. While I'm talking about file formats I may as well suggest how great it would to make sure that when gradient support is implemented in a file format we should have a generic way to exploit that and make those gradient loaders directly available to the gradient tools without needing to write additional code. (Please remind me to file an RFE for this infrastructure change if I haven't done it within a few day.) Sincerely Alan Horkan http://advogato.org/person/AlanHorkan/
