joint-and-wire-type polylines/fixed length line segments?
by Amy 26 Sep '13

26 Sep '13

Hi, I'm after some functionality in Inkscape but unfortunately I don't know what it's called, but I will try to describe it: 1. I draw a polyline (a path of straight line segments with a few nodes). 2. I use the node tool to grab one of the nodes and reposition it. Currently in Inkscape when I do (2) the line segments either side of the node adjust their lengths to accomodate the new position of the node. What I'm after is where the entire line is treated as if the segments were *rigid* (i.e. fixed length) and think of the nodes as hinges. So I drag one of the nodes to a new position, and by virtue of the fixed length line segments the rest of the line is dragged with the node, to some extent. For example you could imagine if I had a straight line with two segments and nodes A/B/C: (A) --- (B) --- (C) If I grab (B) and drag it upwards, this is what Inkscape does (on the left) compared to what I want (on the right): (B) | (B) / \ | / \ / \ | / \ / \ | (A) (C) / \ | / \ | / \ | / \ | (A) (C) | (it renders OK for me in monospace) On the left, the segments AB and BC are lengthened and A and C remain in their original positions. On the right, AB and BC preserve their length, and as a result the entire line is dragged upwards. The particulars of exactly how (A) and (C) reposition themselves is not important to me, as long as they act in a way consistent with AB and BC having the same length before and after. 1. what is this feature called (so I can ask about it/search for it better)? 2. Does Inkscape support this? (say I can toggle between the fixed-length and variable-length modes)? cheers, Amy

divide overlapping objects
by Maarten van der Velde 24 Sep '13

24 Sep '13

If I have three overlapping objects (closed paths), is there a easy way to 'split them up'/divide them using the borders where they intersect? The 'boolean operations' seem to either divide one object by the other, removing the top-most one, *or* cut the path (outline) of one using the other. Conceptually, if I got three cirlcles, each one overlapping partially all the others, after this operation, I'd like to end up with 7 separated parts. Thanks!

How to have different markers along each node of a polyline?
by Amy 23 Sep '13

23 Sep '13

Hi all, I'm trying to write an Inkscape extension that has the following functionality: 1. I create a polyline in Inkscape and select it. 2. My extension takes in a string of predefined tokens, the same number as there are nodes in the polyline, e.g. "square, circle, triangle, circle, circle". 3. The extension places a square at the first node of the polyline, a circle at the second, triangle at the third, circle at the fourth, circle at the fifth (includes end points). I would like the resulting line-with-pictures to still be a line in that I can go to the node editor and adjust the nodes of my polyline (it's just that the nodes have pictures on them now). How can I achieve this in Inkscape or in SVG? (Is this the appropriate list for this question, or should I send to inkscape-devel?) This makes me think that what I want is to specify *custom* markers along a line. I.e. not just marker-start, marker-end and marker-mid, but more of a marker-sequence (so that the middle markers can be different from each other). Is this possible? If not, is there some other way to do this? Perhaps I can do this with connectors instead so that my sequence of square -- connecter -- circle -- connector -- triangle -- connector -- circle -- connector -- circle still *acts* like a line with markers at each node in inkscape (though in SVG it is not "truly" a polyline with markers). I've been trying to read up on connects, but is there further documentation available? In particular, I think I've worked out how to set "inkscape:connector-(type|curvature)" and "inkscape:connection-(start|end)", but what is "inkscape:connection-(start|end)-point"? On examining the XML of a test connector I drew in Inkscape, it was set to "d4" for all the connectors I drew and I'm not sure what this signifies. Also when I convert my path to connectors in my extension, is it up to me to calculate where the path would intersect with the edge of the node? For example if I connect a star to a rectangle I notice that in Inkscape the connector only starts and ends at the edges of the objects, even though the "true" connection handle is in the centre. Is there some convenience function in the Python modules somewhere for me to work out where the polyline would intersect with my node picture (particularly for more complex shapes, like a star)? cheers, Amy

Help Test a Bug
by Martin Owens 17 Sep '13

17 Sep '13

Hey Users, We're trying to clear blocking bugs and one that is quite hard to test needs your help: https://bugs.launchpad.net/inkscape/+bug/1106031 If you're using trunk builds (i.e. from the inkscape testing ppa or other very recent build) then I'd like your help by following these instructions and letting me know if you can get inkscape to crash or not: 1. Save this file: https://bugs.launchpad.net/inkscape/+bug/1106031/+attachment/3606346/+files… 2. Open in inkscape (trunk) 3. Run Extension > Color > Randomise 4. Close inkscape Repeat a couple of times. If you get a crash let me know, if it doesn't crash. Also let me know. Because the code implicated has changed so much, I believe the bug to be fixed already, let's prove it and knock this blocking bug out the way. Thanks for your help, Best Regards, Martin Owens

Difference operation between group of objects and single object
by Guiu Rocafort 16 Sep '13

16 Sep '13

I have a rectangle, also a group of objects which is the result of creating a small circle and applying scatter extension so it distributes along the rectangle borders. Then I try to apply the difference operation but doesn't seem to work. If I ungroup and I apply the operation selecting each circle and the rectangle one by one it works but not as a group. Does Inscape allow to apply the difference operation between a group and a single object ? If it doesn't, some suggestions about how to do that faster ? PD: I'm trying to achieve something like this: http://howto.nicubunu.ro/inkscape_postage_stamps/ Thanks in advance Guiu Rocafort -- Please avoid sending me Word or PowerPoint attachments.

problem with unit selection drop downs
by "René Staffen" 28 Aug '13

28 Aug '13

Hi, Sorry. i wasn't aware that the webmailer (that i use very rarely) uses html as default. here again in plain text: I hope someone can help me. I have a problem with my inkscapes (i had 0.48.2... and upgraded to 0.48.4.r9939 without success, OS: german WinXP 32bit) unit selection boxes. Especially the ones in the document property dialog (but also in some other dialogs). the "default unit" and "unit" drop down lists are empty. they are very small and the drop down button is inactive (grey). So i cannot change the units. I allready tried removing preference file to reset to defaults. i changed the language from german to english. but the problem does not disapears. The only boxes that i could found that seems to work is the one in the toolbar if an object was selected and the one in the stroke style dialog. document propertys/page, document propertys/grids, transform, inkscape preferences/grid, inkscape preferences/Interface are not working. Any hints? regards René

Inkscape->Illustrator, keep layers intact
by Chris Mohler 27 Aug '13

27 Aug '13

Hi list! I usually lurk on inkscape-devel, and this is my first post here. I'm looking for help with creating multi-layer drawings in Inkscape and opening them in Illustrator while preserving the layer structure, if possible. Any tips? I use both programs all the time, but usually when I'm going back-and-forth between the two it's something simple - a trace, a single layer, etc., not a multi-layer composition. Thanks, Chris
