win32 build working again
by Bob Jamison 08 Apr '24

08 Apr '24

The win32 build, which was broken for the weekend, is working again. I just made a "manual autobuild" again, so that we can see how it looks on Windows: http://troi.titan-aeu.com/~rjamison/inkscape/builds/ Bob

Re: [Inkscape-devel] [Inkscape-user] Slow performance on 4.5 MB file [SOLVED]

And please be sure to file a bug/feature request at http://bugs.launchpad.net/inkscape/ In the end there will obviously always be cases where Inkscape is too slow, but Inkscape could most definitely be faster in some cases. And just locking/unlocking the layer should (from an intuitive standpoint) NOT cause such a big pause.

File Export (Save-As) Tests for v0.47
by Tavmjong Bah 18 Nov '09

18 Nov '09

Hi, I've tested all the various file export options under the Save As command. Would the relavent experts for each type please review my comments/questions below? All test were done with Fedora 9 Linux and 0.46+svn updated within the past couple of days. Thanks. Tav General comment: I am having trouble getting Uniconvertor to work from within Inkscape. It won't process files with text (error message about not finding correct font). Files without text produce SVG output (Uniconvertor 1.1.4), independent of which file type is selected. Or error message about not finding SVG file in /tmp (Uniconvertor 1.1.3). I may have screwed something up but Uniconvertor does work when used via the command line (as in "uniconv test.svg test.plt") to directly convert SVG files to other types. Does anybody have it working from within Inkscape under Linux? File Format: .ai: Missing. Failed to load message in extension-errors.log (same error for DXF and ESPI). Works in v0.46. .dfx: Generic AutoCAD export failed to load (see .ai). Plotter version updated. Question: what is the target if the "ROBO-Master output" option is not checked? .emf: Does this still only work on Windows? Uses Uniconvertor. .eps: This is using the same export dialog as PS. Is this appropriate given that the bounding box is handled differently? Speaking of which, while the specifications do say the bounding box should be the smallest rectangle that fully encloses the drawing, it is a common practice (and very useful in scientific work) to define the box to be bigger than the drawing. In reading the specification, it seems to me, that they were more concerned that the bounding box takes into account stroke width, etc. than in prohibiting bounding boxes larger than the drawing size. I think it should be left up to the user to decide this. In the past "Canvas" has been used to refer to the entire drawing area while "Page" has been used to refer to the SVG specified drawing area. The dialogs and command line options should use "Page" wherever "Canvas" is used. .fx I see small bugs in gradients and displaying a pattern. .gpl OK. .hpgl I see bugs in object transformations. Uniconvertor as of 1.1.4 also generates .hpgl files. Uniconvertor doesn't handle Inkscape circles. .odg. Small translation problems. .pdf. Generally OK. Bug in patterns made from a group of objects drawn off the page. Export dialog almost the same as for EPS and PS but small differences in wording and in order of options. Should match with EPS and PS dialog. .plt Uses Uniconvertor. Tool tip etc. state it is AutoCAD plot file... but this is really, as far as I can tell, just HPGL. .png Duplicates "Export Bitmap" menu entry but without handling Filtered objects. .pov Broken in v0.47. Extra lines are added to object descriptions. Works in v0.46 (some paths missing). .ps See EPS and PDF comments. .sk1 Uses Uniconvertor. .svg OK .svgz Broken in v0.47. Works in v0.46 .tex PSTricks OK, PSFrag needs work-around due to Cairo font subsetting. .xcf OK .wmf Uses Uniconvertor. .xaml Objects translated wrong (could be xaml input problem). .zip OK.

InkscapeForum.com for offer to Inkscape.org
by microUgly 06 Oct '09

06 Oct '09

If you don't know, I run www.inkscapeforum.com--a relatively successful phpBB forum for Inkscape users. I created the forum because I knew there was demand and at the time I knew I could devote a lot of time to make it successful. But I was never fond of the idea that a single person would have ownership of the data accumulated from the community. I wanted to offer ownership of the forum to Inkscape.org. Ideally this only needs to go as far as knowing that if I were hit by a bus, someone could step in and take over. I don't know how things are ran on the inkscape.org site, but I would be offering the entire setup to be hosted by inkscape.org (if possible). I would happily continue to moderate, and administer the board if appropriate access were given. And I would redirect inkscapeforum.com to the new domain, or change it's name servers. Anyway, discussion open. Would Inkscape.org be interested in adopting the forum? The forum won't be shutdown regardless of the answer. -- View this message in context: http://www.nabble.com/InkscapeForum.com-for-offer-to-Inkscape.org-tp2467341… Sent from the Inkscape - Dev mailing list archive at Nabble.com.

Re: [Inkscape-devel] rotating guides

In my opinion using ctrl should only make the motion constrained, and not change the type of transformation simultaneously. So: A) when dragging with no modifiers we will move the origin to the pointer location (freely, in 2D) B) with ctrl we will have a constrained translation of the origin along the guide C) with shift we will rotate D) with ctrl-shift we will rotate to increments of the absolute angle and with A), B), and C) Inkscape will snap depending on the snapping parameters. It looks like we're converging here, aren't we ;-) ? What do you think? Diederik

Inkscape scripting API (Draft)
by Glimmer Labs 18 Aug '09

18 Aug '09

Here is the first draft of a Dbus based Inkscape scripting API: http://www.cs.grinnell.edu/~bergsore/inkscapeDbusRef.html (Many thanks to the ConsoleKit team for the scripts and build system I used to generate this documentation.) I would welcome any comments or criticisms, the interface is very much still up in the air so any suggestions, from small changes to major issues, would be welcome. I would particularly like to hear if people think that this would potentially support the ways in which they use Inkscape, or whether there are use cases this doesn't address. If there are lots of uses that this interface does not support, additional interfaces geared towards different users could be added. (In fact there was originally one more interface than there is now, see document_new() for details.) If you like the current API (in general) feel free to suggest additional functions or functionality. Finally, how would you like to see this extended? Dbus has proven to be quite responsive and robust for this application. How would you build off the basic platform of the Inkscape application interface? I will keep the posted link updated as I make changes based on peoples feedback. -Soren

Win32 NSIS installer
by Chris Morgan 03 Aug '09

03 Aug '09

Hi all, Today I decided to take a look at the NSIS installer for Win32, and decided to optimise it. It currently uses a macro and function for reading options from the command line. Since then, FileFunc.nsh has had added to it the GetParameters and GetOptions macros, which make the code inside the installer obsolete. I was amused to see that the option-reading code was made by (a different) Chris Morgan in 2004! For your assurance that I hopefully know what I'm doing, I have had lots of NSIS experience, mainly at PortableApps.com, where our launchers and installer are in NSIS. NSIS is an area I can help in, unlike the one I wanted to do more, https://bugs.launchpad.net/inkscape/+bug/398603, which I'd like to fix but can't really. I also optimised readability and similar through the use of LogicLib's logical code structures. I cleaned up the language sections significantly, using a single macro rather than a section for each, containing a macro. In all of them, polng was equal to lng, with the exception of Japanese which had, incorrectly, jp rather than ja for lng. lng was only used for "..\..\inkscape\*.${lng}.txt" anyway - a mask which matches no files for any language. I'd propose that that line be vanquished as it's not used (historical?). In the meantime, I simplified it into one argument for the two. More on languages later. While doing this I found about half a dozen minor bugs, all of which I've fixed. Starting at line 1382 (old), that set of things had the conditions the wrong way around, so it would only print the detail if it was *empty*, rather than if it was something... utterly insignificant, but a bug :D More importantly, all the code around that section was inefficient, I rearranged it to make it more efficient. Also the deleting HKCU\.svg[z] thing was looking for the wrong thing, fixed that. The biggest bug I found was that single-user installations didn't work (at least judging by the code). The shell var context had been formerly set to "all", and the all users section set it to "all" and had a bit of code which wouldn't ever get executed. I got around this the easiest way, which was just to create an unshown section before it to SetShellVarContext current. All in all, I took it down from 1559 lines (47,874 bytes) to 930 lines (34,534 bytes) (60% of the lines, 72% of the filesize), shrunk the installer output by about 25KB (0.07% :P), fixed some bugs and made it more readable in the process. Now for some discussion on what I reckon having looked at it. Languages: I can optimise those still further, just thought I'd send round what I'd got so far. In particular, I want to change it so that no languages are installed by default; this would speed up installation on Windows exponentially - due to the LZMA solid compression used, each language takes an inordinate time to install. I think I can fix that up too, but I'll need to experiment on it a bit. Moving the files first should help in the technique... I'll try it out and report back. However, back on the main topic, I want to change it so English is not shown on the list (it's really pretty meaningless, it's an empty section... and the SectionGroup is "Translations" of the interface, English is pretty much a given), and so that the only language which is installed is that which the installer is running in. I can do that easily enough. Possibly also the MUI LANGDLL should be displayed to let the user choose the initial language. Presets: we've got the SectionIn 1 2 3 bits all over the place, but aren't using the presets at all (any more I guess from commented out code). I think they should be added back, that way you can have all languages in full, the suggested one in optimal and none in minimal. Also I think that quick launch and desktop icons should be on by default. Start menu: currently this is forced on, in a set location, which isn't very nice. We should use the MUI STARTMENU stuff. I also think that a lot of the DetailPrint bits should be cleaned up to either be removed or so they can be more useful. The welcome and finish pages should get their own images, I'll make a proposal for it. Also the header image should get the new logo; likewise I can do that. Right, I think that's enough for now, though I've probably forgotten something I was going to say, and missed a bug or two I fixed. -- Chris Morgan <chris.morganiser@...400...> I don't need a quote in my signature. It's hard enough surviving as it is without having to find a meaningful quote. Will you forgive me? Or don't you read this bit?

Boost.Intrusive
by Krzysztof Kosiński 02 Aug '09

02 Aug '09

Hello all In my GSoC project I need to represent nodes in a linked list. The requirements are: 1. Obtaining an iterator from the value should be a constant time operation 2. Ownership semantics should be similar to boost::ptr_list - that is, objects are owned by only one container and deleted when erased, though there are special functions that allow transfer between containers and releasing an object from a container 3. The list must have a 'closed' flag that determines the behavior of 2 functions that retrieve an iterator to the next and previous node: If it's true, they wrap around, and if it's not they behave like regular ++ and -- on iterators. Initially I thought about std::list + std::tr1::unordered_map of pointer to node -> iterator, but this is absurd. Then I created my own NodeList class, which worked well enough, but I feel that implementing all the operations is reinventing the wheel. I could use Boost.Intrusive (specifically boost::intrusive::list) to satisfy 1 and 2 out of the box and 3 with a small amount of work. However, I can't find what version of Boost we currently depend on. Boost.Intrusive is a header only library that was released as part of Boost 1.35 in April 2008 (there are no runtime dependencies, so the only possible issue is whether developers run recent enough systems to have it available). It is available in Debian Lenny, as a backport for Etch, and in Ubuntu Hardy LTS. Is it OK to use it? Regards, Krzysztof Kosiński

Extracting a saturation map with SVG filters ?
by Ivan Louette 01 Aug '09

01 Aug '09

I can't figure how I could extract a saturation map (as a greyscale image) with SVG filters. My idea is using it to replace any hue of an image with only one like it's done with cyan in the joined png created with Xara Xtreme Linux Edition. I am searching for a long time already but without success. Perhaps not possible. In Xara I only put a cyan rectangle above the image and apply the "Hue" transparency type. I was able to synthezize all Xara's color effects but this one. ivan
