Impossible to correctly scale LPE stitch subcurves?
by unknown＠example.com 17 Jan '08

17 Jan '08

Hello all, I am trying to fix transformation behavior for LPE (translation, scaling, rotation). I think I found a fundamental problem. Take Stitch Subcurves. Let's say we are stitching between a straight horizontal line, and a line in the shape of: _________________ / / / For equidistance stitch spacing, the stitch start points would be: ____o_____________o / / / o o__________o___________o Note that the distance is taken *along* the length of the line, not just the distance in the x-direction as this would not work in general Now, after scaling in the Y direction: ____o_____________o / | | | | | | / / o o__________o___________o

Fixed size Export Bitmap dialog
by Tavmjong Bah 17 Jan '08

17 Jan '08

Hi, I just noticed that the Export dialog is now fixed in width. This, in my opinion, is a not a good change as one cannot now expand the dialog to show the entire file name path. This means having to click on the file name and use the arrow keys to get to then end to customize the file name, a real pain if doing lots of exporting from one file. Tav

I rewrote all widgets that LPE uses at this moment. This fixes the LPE dialog. The document properties window seem fixed (with a low prio bug still lingering), but there is a memory leak now until all registeredwidgets have been recoded. It is a very straightforward simple task to fix them, volunteers? (A nice way to get more familiar with the widgets!) Regards, Johan

Valgrind Inkscape
by Joel Holdsworth 17 Jan '08

17 Jan '08

Hi Again, I just tried running inkscape in linux with valgrind for the first time ever, and it reveals some interesting results (attached). It seems that libgc's malloc function has a bug where the library will operate using uninitialised data. "Conditional jump or move depends on uninitialised value(s)" It might be quite cool to have a bit of a proper play with valgrind. It seems really quite hi-tech, and I'm hopeful it will be able to reveal quite a few memory related bugs. Joel

Function plotter and notebooks

Attached I have a Function plotter INX file without the notebooks. The dialog is ugly, very ugly. But can someone check to see if it works on Win32 without the notebooks? Thanks, Ted

strange behaviour on feTile
by Felipe Sanches 16 Jan '08

16 Jan '08

Today I have tried to implement the feTile filter primitive renderer. What surprises me is that the renderer class does not seem to be even instantiated when I try to render the filters-tile-01-b.svg test from the W3C SVG 1.1 test suite. ( http://tavmjong.free.fr/INKSCAPE/W3C_SVG/htmlInkscapeHarness/full-filters-t… ) in this SVG test, the filter effect is applied to an empty <g> node. There is a comment about it:  <g filter="url(#feTileFilter)"/> I think that this is causing the problem: a void node would not invoke the renderer requiring an area to be rendered. Anyone can give me some hint? my current feTile implementation is attached to this message Juca

Add to a blueprint?

How can I add comments to this blueprint at launchpad: https://blueprints.launchpad.net/inkscape/+spec/richer-extension-parameters I wanted to add a suggestion for an angle selector widget, like the one proposed for GIMP here: http://gimp-brainstorm.blogspot.com/2007/12/angle-widget-for-motion-blur.ht… -Rob A>

Adding patterns to patterns.svg
by Rob Antonishen 16 Jan '08

16 Jan '08

Is there a trick to adding new patterns to the patterns.svg file? I created a new user pattern in an image using the objects to pattern option and saved the file. I then cut out the <pattern></pattern> in a text editor and added it into patterns.svg. It shows up in the pattern drop list, but does not actually work. Here is the pattern I created: <pattern patternUnits="userSpaceOnUse" width="40" height="40" patternTransform="translate(0,0)" id="pattern6158"> <path sodipodi:nodetypes="cccccccccccccccccccc" id="path6099" d="M 20.5,0.5 C 20.5,13.531254 40.5,13.531255 40.5,0.5 M 0.5,0.5 C 0.5,13.531254 20.5,13.531255 20.5,0.5 M 30.5,10.5 C 30.5,17.015628 35.5,20.25 40.5,20.25 M 10.5,10.5 C 10.5,23.531255 30.5,23.531255 30.5,10.5 M 0.5,20.25 C 5.5,20.25 10.5,17.015628 10.5,10.5 M 0.5,20.5 C 0.5,33.531255 20.5,33.531255 20.5,20.5 M 20.5,20.5 C 20.5,33.531255 40.5,33.531255 40.5,20.5 M 30.5,30.40625 C 30.5,36.921878 35.5,40.1875 40.5,40.1875 M 0.5,40.1875 C 5.5,40.1875 10.5,36.921878 10.5,30.40625 M 10.5,30.40625 C 10.5,43.437506 30.5,43.437505 30.5,30.40625" style="opacity:0.9;fill:#ffffff;fill-opacity:1;fill-rule:nonzero;stroke:#000000;stroke-width:1;stroke-linecap:butt;stroke-linejoin:miter;marker:none;marker-start:none;marker-mid:none;marker-end:none;stroke-miterlimit:4;stroke-dasharray:none;stroke-dashoffset:0;stroke-opacity:1;visibility:visible;display:inline;overflow:visible;enable-background:accumulate" /> </pattern> Suggestions (or pointers) on what is wrong with this pattern? In the original file it works file as a pattern. One note is that I edited the width and height to allow the strokes to overlap without gaps, but again, it works well as a pattern in the svg document. -Rob A>
