Effect errors
by unknown＠example.com 08 Apr '05

08 Apr '05

I often write effects in Python that raise an exception, and therefore send no output to STDOUT. Inkscape responds with: Extension::Script: Unknown error for pclose : Success /tmp/ink_ext_qL04b1:1: parser error : Document is empty ^ /tmp/ink_ext_qL04b1:1: parser error : Start tag expected, '<' not found ^ ** (inkscape:6769): CRITICAL **: virtual void Inkscape::Extension::Implementation::Script::effect(Inkscape::Extension::Effect*, SPView*): assertion `mydoc != NULL' failed Is that just a healthy warning? I also notice on occasion (though I can not reproduce it on command yet) that I experience a crash soon afterward. So my question: Could stderr generated by scripts be captured into a gui window? This is of course unnecessary because, I can always run inkscape from the command line for debugging. But I thought the information might help users track down dependencies. Aaron Spike

Basepoint of objects
by Craig Bradney 07 Apr '05

07 Apr '05

Hi Just wondering if theres any plans to implement the ability to change the basepoint of an object. I just submitted 1178771 for this. It'd be really nice to be able to change the position or rotation based on all of the corners and centre, and perhaps midpoints of the sides of an object. Please refer to Scribus' Properties Palette for an example if its interesting to Inkscape. Craig Scribus Team

Yes, I see now that the rotation value doesnt seem to be shown anywhere after rotation is done, which is why it may not apply to Inkscape (/SVG) in this instance. Or have I missed where this is stored too? :) > > C) Is there a way to accurately set the rotation centre to the TL, TR, > > BL, BR and C of the bounding box? > > Yes, once snapping is done. > > > Perhaps I've missed an easy way to say, eg, set a frame 100 units from > > the right of a page, or from another object. > > Ah, you mean you want the X/Y values in the selector controls to be > switchable to different corners of bbox? That might make sense, with a > small grid of toggle buttons to choose one of the corners or mid-sides > or the center. Yes.. thats basically it. In Scribus it is also used for the rotation centre.

Scripting
by unknown＠example.com 07 Apr '05

07 Apr '05

Sorry I don't know enough about the subject to formulate more proper questions. I'm interested in learning more about the python scripting support. I realize it is a ways down on the roadmap still, but occasionally I hear a bit about it. Is there anything in CVS that I can try or anything I can read to learn more and watch it develop?

inx files
by unknown＠example.com 07 Apr '05

07 Apr '05

I have read through most of the inx files in the extensions directory and I have created a few myself. I would like to learn whatever else there is to know about inx files. Who should I ask? Where should I look (in which source files)? Today I am wondering specifically about the param elements as seen in grid.inx. When I see the param element I expect two things. That there will be a gui facility for a user to change those values. And that those values will be passed to my script. When I tried neither happened. I think I've heard some chatter about the gui not being finished. But I was surprised that the values weren't passed on the command line. Am I at least in the ballpark with how this will work?

Re: [Inkscape-user] some pdf creation info
by Erik 07 Apr '05

Craig, I have used the pdf printer route with Inkscape numerous times but have always been a bit disappointed. I tried again this evening using a recent cvs with a test file containing a rectangle (+radial gradient) +star (+linear gradient) + spiral +some text. While this is hardly of mind shattering complexity there was an awful lot of huffing and puffing. Saved as svg the file size was 6KB. Saved as pdf the file size was 959KB. then I changed the gradients to uniform grey. Saved as pdf the file size was still 575KB. Some observations. I am using the PrimoPDF driver as downloaded, and saving in Screen mode. Win2000 and PentiumIII933. The saving takes ages - as in a couple of minutes. However, once it gets there the pdf contains the colour and the gradients. I remember trying transparency as well some time ago and that was ok too. The line quality onscreen is pretty bad but improves with magnification up until the jaggies come in. The slow speed and large file sizes are definitely a concern. I have not looked at what a "realistic" file would be like in terms of time. But if a svg file of say 60KB produced a pdf file of 10MB then I would doubt its use! Having said that, I must admit there are lots of issues with PDFs and even a very fast program such as Xarax. There the gradients/transparencies/other special effects are often changed into bitmaps and produce huge files. Interestingly, exchanging gradients for say 20% grey in Xarax brings the file size back down to sensible figures. We do not seem to have quite got there yet. Xarax also does not seem to suffer the time problems that Inkscape does. However, we know there are time problems and have done for some time. Maybe at this stage we should be thankful that we can get pdfs in this way at all. There are also many PDF printer solutions out there. It would be good for someone to look at a few of them and find out which is the most efficient at this stage. Certainly pdf capability is a limiting factor in my use of Inkscape at present.

> My 16x16px icon got scaled down to about 10px in the toolbar. What's the magic here? I would like to be able to tell you why the icons are the size they are, but the icon drawing code we inherited from Sodipodi is scary and nobody quite understands it... :P I'll CC the devel list in case perhaps the gtkmmification team has made any breakthroughs studying and/or rewriting that code. -mental

Re: [Inkscape-user] autosave ?

The one catch is that for crashes due to failed assertions (like this one), it isn't triggered yet. (I'm CCing the development mailing list, if anyone's interested in attacking this right now: At least on Unix, this is relatively easy to fix -- just set up a SIGABRT handler similar to the SIGSEGV handler we have now. The one catch is that the handler will need to disable itself as soon as it is triggered, because the autosave code raises SIGABRT when it is done. Also we should make sure we've got SIGBUS covered if we don't already.) -mental

New dialog/panel junk

I've started a bit of stuff on my "Panels" replacement for subclassing dialogs. It's on the Wiki, linked under "User Interface Discussion" http://www.inkscape.org/cgi-bin/wiki.pl?DialogReplacement Bulia, see? I have a plan. :-)
