Rationale for typography canvas defaults?
by Matt Gushee 05 Jul '12

05 Jul '12

Hi, all-- First of all, if this is not the right list for this question, please direct me to a better one. Anyway, I am interested in using Inkscape (together with FontForge) for font design, and thus I am trying out the more-or-less latest development version from Bazaar, with the typography extensions. And I'd like to thank the folks developing these extensions; I know good typography tools are not easy. I am curious, though, about why the default and maximum em sizes are what they are: 1000 and 2000, respectively. I've been Googling hard for info on the "right way" to design glyphs for Freetype or Opentype fonts. I'm sure noone will be surprised to hear that it's hard to find definitive info, but so far I have found: * There doesn't seem to be any universal agreement on the best design size, BUT * An 1000-unit em square is seen as an old-school measurement, associated with Type 1 ("Postscript") fonts, and * Apple uses a 2048-unit em square, and of course Apple is right about everything (just kidding!), and * A size that is a power of 2 is thought to make scaling more efficient and/or accurate, leading many designers to favor 2048 or 1024 units. At any rate, to the extent there is consensus, people seem to prefer 1024 or 2048 these days. So I'd like to know why 1000 is the default, and if there is a technical reason for setting a maximum size of 2000. Meanwhile, I'm going to go with 2048, and will tweak the code in my installation to allow that size, and see how it works. I'll report back if I notice anything interesting. -- Matt Gushee

GTK+ 2.20 support status
by Alex Valavanis 03 Jul '12

03 Jul '12

Hi All, I wondered what people's thoughts are on our support for GTK+ 2.20... A quick check reveals that we now have 100 conditional code blocks to support the obsolete symbols provided by GTK+ 2.20, so it adds a bit of a burden on developers and it makes the code horrible to read in places. Most stable/LTS releases of major linux distros provide newer versions of GTK+/gtkmm than 2.20. The exception is Debian Stable, but that's a pretty special case (i.e., ancient versions of everything!) If we were to drop our support for gtk+ 2.20, the main casualty would be Ubuntu Lucid. However, (a) there are two newer stable versions of Ubuntu and a newer LTS release available, (b) we have already bumped our Cairo dependency to a version that is not in Lucid, and (c) I guess that trunk will inevitably reach the point where we leave some older distro versions behind. So... the question is whether we continue supporting a big chunk of conditional code or whether we drop support for gtk+ 2.20. Any thoughts? AV

Text in SVGs exported from Sibelius
by Daniel Spreadbury 01 Jul '12

01 Jul '12

Dear Inkscape developers, Sibelius is a Qt-based application that uses Qt's built-in SVG support to export SVG graphics. These SVGs open fine in various web browsers (e.g. Safari, Chrome, Firefox, Internet Explorer), but the text does not appear correctly in Inkscape. Please see the attached example. Does this problem lie on Inkscape's side, or on Qt's side?

Polar Arrangement - Review
by Denis 29 Jun '12

29 Jun '12

Hello all, I've recently finished implementing my feature, that is, arrange objects in a circular shape. Here you can find the proposal I wrote before implementing: http://issuu.com/ddeclara/docs/inkscape_radial_arrangement My source code is available on launchpad at: https://code.launchpad.net/~declara91/+junk/inkscape-denis And for all ubuntu users out there, there is a ppa called: ppa:declara91/inkscape Where I have compiled packages of my branch. The package name is: inkscape-denis I would be great if someone could check my branch out! (And maybe one day, it could be pulled in trunk :D) Thank you in advance, Denis

How to return an error from an extension
by Gerrit Karius 28 Jun '12

28 Jun '12

Hi everybody, After calling an Inkscape extension which generates output on stderr, a little info box pops up that says: "Inkscape has received additional data from the script executed. The script did not return an error, but this may indicate the results will not be as expected." That's all fine, but how do you actually return an error code from a script? I tried "sys.exit(1)", but that didn't work. Is there an example script shipped with Inkscape that returns an error? Many thanks for an answer, Gerrit

Hi Inkscape devs, In the current Ubuntu 12.04 LTS release, when printing without print preview, Inkscape submits print jobs with zero sized media, causing print failure [1]. I have just subscribed the "Inkscape Bug Team"; is there anything else that needs doing to get the bug report into suitable shape? Many thanks!

wiki administration
by John Cliff 27 Jun '12

27 Jun '12

Hi Guys, We really need to do something with regards to the wiki making it harder to sign up spam accounts, we seem to be getting a couple of dozen of junk accounts a day, with most days having no new legit accounts. I dont want to stop people being able to sign up easily, but at the same time, the way we currently has it seems to be balanced all wrong. Who is it that has admin rights for stuff like wiki extensions and the base settings? Cheers John

layer styles?
by Michael Grosberg 26 Jun '12

26 Jun '12

I'm working on a technical drawing which is made up of a large number of objects, with a rather limited number of basic styles (this is common in engineering - drawings have layers with a different line style for each layer). So, I created a layer for each style: one layer for dashed lines, one layer for shapes with white fill and no stroke, etc. As it turned out, it was difficult to just draw all of the shapes of one style and then move to another, as they had to interact. So, as I was moving across the drawing and adding shapes, I had to continually set the style to match the current layer I was drawing in. What I really wanted was something like Photoshop's "layer style", Or layers in CAD drawings, where whatever you draw on a layer receives the same style. I was able to do this using the XML editor by copying and pasting the style attributes of existing shapes into the layer nodes, and unsetting the fill and stroke for new shapes. Whatever I drew after that received the layer style. Now my question is this: Is there a mechanism in place to do this without editing the XML? If not, do you think there should be? I think it would be useful.

pdf import again: poppler native vs. poppler cairo
by the Adib 24 Jun '12

24 Jun '12

Hello All, as the problem is still there I would propose following intermediate solution: currently in the codebasis there is also an pdf import via poppler-cairo. This one is disabled. I would like to enable this as an additional pdf import possibility. We have to decide later when it comes to the release which one to integrate into the release. so we can test in parallel the two options. we have a big tester basis (compared to separate launchpad branch) we get the possibility to switch to an tested poppler-internals independent solution (while using poppler) I there is no big NONO I will go forward and enable this within the next days. attached the patch that is needed for this (tested on windows, should work on Linux) regards, Adib.

0.47 support status
by Alex Valavanis 24 Jun '12

24 Jun '12

Just wondering what the official position is on the 0.47.x branch. A number of bug reports have been filed recently about build failures with recent versions of Glib, Poppler etc. At the moment, we list 0.47.x as being supported [1], but as far as I know, we have no plans to backport any fixes for the build failures, so it isn't actually usable on current linux distros. As such, would it be appropriate to "retire" the branch and encourage users to upgrade to 0.48.x? Cheers, AV [1] https://launchpad.net/inkscape/0.47.x

Is there a more user friendly way to describe the 'Vacuum defs' function ? How about we rename something like 'Document Cleanup' ? Maybe even a dialog with checkboxes and explanations of the various options: Cleanup and remove the following unused definitions from this document * Unused gradients * Unused color profiles * Unused patterns * Unused markers * Unused scripts * Unused clipping paths * Unused filters etc

libvisio is available
by Alexandre Prokoudine 20 Jun '12

20 Jun '12

Hi, During this GSoC a LibreOffice student and her mentor implemented support for VSD, binary Microsoft Visio documents, that Microsoft never bothered to publish a specification on. The student managed to do far more that she expected and ended up with a nice C++ library for parsing VSD called libvisio that supports all geometric primitives, formatted text, embedded stencils, all kinds of fills and strokes etc. The long story is here: http://libregraphicsworld.org/articles.php?article_id=41 Now, the short story is that the libvisio library (currently at v0.0.7) has a tool called vsd2xhtml which converts VSD to SVG documents and embeds them into XHTML documents. So it looks like it's possible to write an extension for loading VSD directly to Inkscape. Otherwise you have to do some text editing to get an SVG out of that XHTML. Howevere there is a party trick involved. Since VSD files are often multipage, the convertor dumps every page into same XHTML file one by one. So if someone decides to have a go at it, I think it would rather be loader similar to our PDF loader which provides preview for letting a user to choose a page for importing.

GtkObject stuff
by Alex Valavanis 08 Jun '12

08 Jun '12

Hi All, I've created a branch at lp:~inkscape.dev/inkscape/gtk_object_removal [1] in which I have started trying to rebase SPCanvasItem on GObject rather than GtkObject. I don't really know what I'm doing with Glib/GObject so I have made some (un)educated guesses about how to replace bits of the functionality! The code compiles and gets rid of a huge number of the remaining GTK+3 build errors, but there are major runtime issues (lots of crashes & Glib warnings). Please could someone who knows about Glib memory management take a look at this and give me a couple of pointers about what I'm doing wrong? Am I completely on the wrong track here? Thanks, Alex [1] http://bazaar.launchpad.net/~inkscape.dev/inkscape/gtk_object_removal/chang…

Regarding variable thickness lines
by Sharad Dixit 06 Jun '12

06 Jun '12

hi, I am new to inkscape development . I'm not sure I have all the definitions perfectly clear, but I'll try to explain my query as well as I can. Is this functionality already exist in inkspace i.e to create a line of variable width which would allow us drawing curves but where each node could have its width set so that the line width changed from node to node. I've also tried a couple of other vector graphics programs, such as Illustrator and Xara but this functionality doesn't exist. Thanks a lot -- Sharad

Pass original file path to script extension
by Gerrit Karius 06 Jun '12

06 Jun '12

Hello everyone, I'd like to reference external svg files in my document and process them via an extension. I know that Inkscape will not render them, but I am using an external call to the Apache Batik framework which can resolve external dependencies. The problem is, extensions are called on a temporary copy of the current document (usually in some temp folder), so all relative path references are broken. Is there any way to make an extension call on the original file, or somehow pass that file reference to the extension as a parameter? I only found this forum thread where people are guessing that this is not possible:http://www.inkscapeforum.com/viewtopic.php?f=5&t=1156 Does anyone of you devs know a workaround? Many thanks in advance,Gerrit

Verb for swap fill and stroke?

Hi there. I thought it would be nice to add a verb to swap fill and stroke, but alas - I can't figure it out. I've pasted my feeble attempts below in case anyone has pointers. I barely dabble in C/C++ so I might be barking up the wrong tree entirely... Thanks, Chris Tried adding something like this to verbs: case SP_VERB_SELECTION_SWAP_FILL_STROKE: Inkscape::UI::Widget::SelectedStyle *ss; ss->on_fillstroke_swap(); break; But get this: ui/widget/selected-style.h:223:10: error: ‘void Inkscape::UI::Widget::SelectedStyle::on_fillstroke_swap()’ is protected verbs.cpp:1136:27: error: within this context

New snap modes proposals
by Valerie 01 Jun '12

01 Jun '12

Here's a few snap modes that could be useful: 1. Snap to parallel If there are one or several angled guides around, any straight line you're drawing will snap to a direction parallel to the direction of those guides. It's like drawing paraxial lines, except not just constrained to horizontal and vertical lines. Useful if you need to draw a lot of diagonal lines for example. (by snapping, it means it will snap when the angle you're drawing approaches that angle. You won't be constrained to just drawing towards those directions) 2. Snap to orthogonal Same principle as the above, except in a direction orthogonal to existing guides. 3. Snap to node alignment When you're drawing an object with straight lines, any new point will snap to align to existing points of that line. I'm asking this because creating open-ended rectangles and more complicated straight-line shapes (examples: folder-like shape, thick U shape etc.) are a pain. Right now I have to either: - create several rectangles - align - combine - open up any extra segments Or: create nearly as many guides for snapping as the number of lines I want to draw (and then I have to delete them) Or: do a so-so job, open up the align dialogue and tediously align each group of nodes In fact, this snapping is the default behaviour I wish I'd have for paraxial drawing mode, but a snap mode should make a decent compromise for everyone. 4. Snap to guide point direction This one requires a guide point object first. When you're drawing a straight line, the line will snap in the direction of that point. Useful for perspective drawing, especially if the vanishing points are very far off from the drawing area.
