toolbar refactoring
by unknown＠example.com 20 Oct '06

20 Oct '06

I've committed the first step in refactoring the toolbars. So far only the calligraphy toolbar has been updated. Andy's given it an initial shakedown, and suggested turning it on by default. If anyone wants to turn it off, adding this under the "options" group in preferences should do the trick: <group id="options"> ... <group id="stocktoolbars" value="0" /> Give it a spin and see how it works with the platforms, themese, etc.

SVG validity wants a few minutes of your coding or SVG expertise time
by Ruud Steltenpool, http://svg.startpagina.nl 20 Oct '06

20 Oct '06

Open ClipArt and Inkscape do a pretty good job in promoting SVG. However quite a bit of content on the web that is called SVG, is actually only something that looks very much like SVG, but is not. "Not valid" breaks the principle of a standard. Therefore activities are started and some first code is hacked together to start changing that: http://openclipart.org/wiki/SVG_Testing#Previous_Tools Next to code detecting errors based on DTDs and later also RNGs there's also code that gives the content coder advice, also to help workaround viewer implementation errors. If you have some expertise in SVG or general XML, please invest a little bit of your valuable time. Thanks

Has anyone done a batch upload script for cchost? We have literally hundreds of lesson plans to put up on TeachForward over the next few months.

Inkscape for OS X on a demo CD in SVM Mac
by jiho 19 Oct '06

19 Oct '06

just a quick message to let you know that the OS X version of Inkscape is included in the demo CD that ships with SVM Mac[1] this month. SVM Mac is a french magazine specialized on the Mac (as the names says... SVM stands for "Science et Vie Micro" by the way). It is presented as "A clone of Illustrator... but free". I hope people trying it will see that is is much more than a clone. http://www.svmmac.fr/ JiHO --- http://jo.irisson.free.fr/

LWN Article on SFC w/ Inkscape mention

LWN is running an article right now about the Software Freedom Conservancy, explaining what it's for and why to join. They mention that Inkscape is a part of it. http://lwn.net/Articles/204870/ Since it is subscriber-only, I've attached the article for those not subscribing to LWN. Bryce

your change to Makefile.mingw.common
by bulia byak 18 Oct '06

Bob, after this change http://svn.sourceforge.net/viewvc/inkscape/inkscape/trunk/Makefile.mingw.co… Inkscape fails to run on Windows 2000, saying "cannot find entry point freeaddrinfo in ws2_32.dll". I tested this on two different builds made by ACSpike and Scislac. Please fix or revert. Thanks! -- bulia byak Inkscape. Draw Freely. http://www.inkscape.org

Structure to store Z-ordered shapes
by Jean Morissette 17 Oct '06

17 Oct '06

Hi all, I would like to know what structure do you use to store shapes in Z-order. It seems to me that a simple linked list would perform poorly for a large number of shapes, since it has a time complexity of O(n) to find the index (the z-value) of a shape. So, I was thinking at two other structures. The first one would be similar to a linked list except that each node would store its own z value. However, since the Z order is only a "less than or equal to" relation, Z values don't need to be equal to their index in the list or even be continuous. So, this class would not waste time to reuse the indices from removed/moved shapes. Operations like add-last, bring-to-front, send-to-back would allocate a new Z-value each time they are called. And operations like remove would not adjust the indices of the other nodes. So, all operations would perform in O(1) time cost! However there is a disavantage of not resuing indice. This class cannot perform an illimited number of some operations (because these operations allocate a new Z value each time they are called). However, this should not be a limitation in real world applications, because that I would be surprised that a user performs more than 2^31 operations (for an integer z value). Another disavantage is that it's not possible to know the real value of the Z order; a Z value makes sence only by comparing it with another. The second structure doesn't have these limitations but it's more complex to implement and a little bit less performant. This structure is a balanced tree where the predicate to insert a node is the in-order index in the tree. The main idea is that the index of a node (thus it's Z value) can be computed by traversing the tree upward to the root, thus in O(log n). So, the nodes don't have to keep its own Z value, and don't need to adjust them. All other operations perform in amortized O(1), since we may need to make some rotations to balance the tree, which should be really fast in practice. Note that these structures assume that a shape *is* a node, i.e. having a reference on a shape means that we have a reference on the node. Thus, we don't need to find the node corresponding to a given shape. What so you think of these structures? What structure InkScape actually uses? Thanks for your comments, Jean

Yep, there are two strategies for this: 1.) there is a commandline script as part of ccHost, which we could use to create an extension that would let inkscape upload to ccHost. 2.) Another approach which isn't so hacky is to help me add webdav support to ccHost so we could simply use webdav in gnome-vfs (which inkscape already supports) for posting up files 3.)
