>I noticed that it seems to take a variable time to bring up the Tutorial >file and the Keys and Mouse file. Chasing it a bit further I got into "low >on virtual memory" messages from windows and then crashes. Looks like we need boehm, and we need it NOW. I guess Linux does its memory cleanup properly, so there's no garbage left when the program exits. I work in Inkscape for hours when drawing, and I run it literally hundreds of times when doing development, with no slowdown. I guess Windows is another matter entirely... >After a couple of calls of the Tutorial file, but before crash, I tried to >use the Freehand tool and it gave very erratic performance indeed. >Sometimes >no curves, sometimes small straight sections instead of curves etc. Not a >good scene.

simplify command
by bulia byak 09 Mar '04

>while on the topic of simplification: the rotate/grow >behavior is mostly due to the fact that you set the >treshhold of simplification according to the size of >the object. if the treshhold is fixed, the shape won't >grow. the rotation is extremely odd, i have no >explanation for that. I think it's intuitively correct for the threshold to depend on the size of objects; if this causes rotation&growth, I think we can live with that, because this only affects a closed shape and only after it's been simplified to the extreme already. >also, you set a default >treshhold of 0.02, which is very small. the meaning of >the treshhold is sort of the max deviation between >original and approximated. you need at least 1.0 to >make simplification useful. It's not 0.02, it's 0.02 multiplied by the size of the object. While this value is small, it still does some simplification for some shapes, and it's set intentionally low because it's supposed to be accelerated by repeating the command fast (press and hold Ctrl+L). I found that when acceleration ups the value to 0.1 or more, this cracks almost any shape, and with 0.2 or more, the shape degrades to a one- or two-node path quickly. >anyway, i just understood why the splotchs were >appearing in the offsets, but don't know how to solve >that. probably going to need a big rewrite of its code... Do you mean only splotches (bug 866838) or general distortions (877019), or are they the same problem? Anyway, consider that the relative size of the distortions lessens when applied to a larger object. So a workaround I use when I need to offset a small object is this: scale the object up 10x, do the offset, scale it back. This suggests that the severity of the problem can be reduced if you make the algorithm somehow use a finer scale so it would "think" that the object is larger than it is, and then scale the result back to original size. Do you think it's feasible? While not eliminating distortions completely, this could reduce them so that the command will be usable in all scales, and it does not require a major rewrite (I think). _________________________________________________________________ Store more e-mails with MSN Hotmail Extra Storage � 4 plans to choose from! http://click.atdmt.com/AVE/go/onm00200362ave/direct/01/

Line skewing bug (851008)
by Bryce Harrington 09 Mar '04

09 Mar '04

Summary: line of skewed object not displayed skewed Bug ID: 851008 ------------------------------------------------------------------------ Hi I skewed an arrow in Sodipodi and the line was displayed with constant width; that's what I wanted. But unfortunately the line's nodes were not moved but the arrow was skewed (transform="matrix...). It would be great to have an option where I skew the shape but the line stays constant-width: no transformation is applied, but instead the coordinates of the path are changed. Anyways, the display is incorrect AFAICS, check http://www.pinkjuice.com/temp/sodipodi/skewed_arrow.png In Squiggle, some edges of the arrow are thinner than other edges (correct AFAICS), but not in Sodipodi. source: http://www.pinkjuice.com/temp/sodipodi/old_note.svg Tobi -- Tobias Reif (tobi__r) tobiasreif pinkjuice com ------------------------------------------------------------------------ I've also found the current behavior to be a bit wacky, especially for technical drawings, where you want to maintain constant line width for all the shapes in the chart. However, I'm not really sure this is is a bug - perhaps this is a feature request? Would it be very difficult to implement a capability such as described above? Bryce

Cumulative Include Dependency Check
by Bryce Harrington 09 Mar '04

09 Mar '04

We've been noticing some excessive rebuilding of the tree when certain header files are modified, due probably to too many header includes (either direct or indirect). This causes two problems: A) Files take longer to pre-process, and B) files get recompiled even when they don't really need to. The following report quantifies the problem on a per-file basis. IDC (Include Dependency Count) - the number of source files that have to be recompiled if this file changes. IC (Include Count) - the number of files that could trigger a rebuild of any files that include this file. IDP (Include Dependency Product) - is the product of IDC and IC, and is used to indicate files where the problems are worst.

The way that SVG does markers is via the 'marker-start', 'marker-end', etc. style tags. Unlike most other style tags, like line caps, the markers use uri's that point elsewhere in the document for the definition of what to be drawn. I.e.: "marker-start:url(#mArrow);" The place that the mArrow item is defined is in the <defs></defs> section of the SVG document. If you look on the screenshots page down at the bottom, there's an example I made of some markers, and you can download the svg document by clicking on the screenshot to see how the SVG is laid out. The code in the codebase currently has some buttons that will put the marker-start style tag on the lines, which is fine if mArrow is already present in the <defs> section (i.e., if you manually write it into the doc). So the next step is to figure out how to make it automatically insert it when the user clicks that button and adds an arrowhead to a line in the drawing. Ideally, we should also remove the def when there are no longer any lines using it. The gradients work in a very analogous way, so it's possible that code can be stolen from there. I haven't looked at the gradient code at all so am not sure what's there. Would you like to take a look at it and see if you can understand how it handles adding/removing its defs items, and if the code could be reused in some fashion? If we can get this defs insert capability done, I *think* that'll be enough to get the feature officially included. Beyond that, then things get fun. ;-) Ultimately I think we want some way to let users define their own markers. Bryce
