But we haven't had much in the way of concrete API proposals (nor implementations to go along with them!). And it seems that the current set of cairo maintainers do not have the expertise to come up with either of these on their own. So I think we're going to need some further input from *somebody* before we'll see concrete progress on this front. Do you know of anyone (perhaps yourself) that could provide some or all of the following: * Concrete use case to describe what is missing at the application<->cairo boundary. * A concrete API proposal to satisfy that use case, (and a minimal API that doesn't multiply existing cairo entry points exponentially). * An implementation of that API. I'm looking forward to further input here, since I'd love to be able to say that cairo has a good answer for people needing whatever is missing here. -Carl -- cairo mailing list cairo@...278... http://lists.cairographics.org/mailman/listinfo/cairo

Inkscape 0.48 status and proposed release plan
by Joshua A. Andler 12 Jan '10

12 Jan '10

Hey All! Are there any larger features people are planning on still for this cycle that aren't well known? I know of the following still outstanding: *Krzysztof's new Node Tool *Soren's DBUS work (provided Ted is able to do his magic on it) *JonCruz's Adaptive UI work I assume all kinds of smaller, less intrusive things are still on their way. However, I just want to make sure we keep track of the big things to keep this cycle tight and under control. Proposed release plan: Mid-February for Chill Beginning of March Frost (Bug Hunt begins) End of March for Feature Freeze End of April for Hard Freeze Sometime in May for Branch & Release I am planning on maintaining branches to patch in bug fixes for point releases this time. So we most likely will not do a bug hunt goal of 500 this time if things don't break badly (perhaps 300 if we're in decent shape, which makes the proposed plan feasible). Cheers, Josh

Objects ("patterns") along path - pathscatter extension
by Hans Meine 11 Jan '10

11 Jan '10

Hi, background: I want to model some room with rows of chairs, not necessarily along straight lines however. Furthermore, I want to be able to access each chair from python, in order to change appearance depending on status in a reservation system. Thus, I have been looking into an "create objects along path" functionality, and found the pathscatter ("Generate from Path/Pattern along Path") extension, plus some "path effect" which I could not get to work and did not find any documentation on. I also had a lot of problems with the pathscatter extension, which I would like to discuss with you and possibly provide fixes for at least some of them. (I am an experienced programmer, in particular with python, but not very familiar with inkscapes code or even GUI yet.) First, my impression was that the extension is slow (I think there's a lot of potential for improvements, since it looks like a straightforward but not very efficient python implementation) and not very well integrated into the GUI, which is probably a typical problem with scripted extensions (I have experience with Gimp's script-fu stuff). For instance: 1. The menu has no accelerators, which makes it inconvenient to start without using the mouse. 2. It has an apply and a close button, but the apply button does not close the dialog, although the only sensible (actually: possible) action after it is close, since it modifies the selection, and the dialog is modal. 3. The dialog is modal, but does not check whether its preconditions (two objects selected) are fulfilled, so you end up making settings, getting an error message on "apply", need to close, fix the selection, and re-open it again (suffering from 1 again). 4. Also, there does not seem to be any good documentation or even help within the program (for instance: icons, tooltips or "whats this" texts, ...); the best information I found was the python comments at the top of pathscatter.py, which should probably be at least put up on some wiki page. Speaking of preconditions, it took me more than an hour to understand how to use the extension, simply because I tried it only with a rectangle as pattern. The results were incredibly... wrong. That's because the extension seems to work only with paths (that is - circles seem to work) - this could surely be improved either by a) allowing rectangles, which should be possible at least in the "snake" mode, or by b) automatically converting other objects into paths. Actually, my plan would be to implement both a+b, since I then realized that with just b) (which is probably the easiest to implement) I have yet another problem: in the "repeated" mode, I am still getting only a single path as result, which contains several path components. For my use case, I really need separate objects, in order to be able to differently style the chairs. I have some basic coding questions, which I will put into a separate posting. -- Ciao, / / .o. /--/ ..o / / ANS ooo

Shifting UI
by Jon Cruz 11 Jan '10

11 Jan '10

I've gotten a first part of the shifting UI done. Toolbars can now be somewhat repositioned. The alternatives are hardcoded at the moment, but to see that just hit widgets/toolbox.cpp and uncomment: //#define ENABLE_TASK_SUPPORT 1 I've left that defined out for the moment in case the other cleanup did not fix the 64-bit issues. If someone can check that, it would be very helpful.

Geom::OptRect and "warning: dereferencing pointer ‘<anonymous>’ does break strict-aliasing rules"
by Alex Leone 10 Jan '10

10 Jan '10

I get this warning everywhere an OptRect is used. For example: SPItem *item; Geom::OptRect r = item->getBounds(sp_item_i2doc_affine(item)); if (r) { Geom::Point p = r->min(); //... will give the warning "./2geom/interval.h:82: warning: dereferencing pointer ‘<anonymous>’ does break strict-aliasing rules". To fix this, shouldn't getBounds return optional<Geom::Rect>? Making an OptRect class seems the wrong use of boost::optional. To remove OptRect: isEmpty() becomes "if (optional<Rect> r)". unionWith(OptRect const &b) becomes another method in Geom::Rect, unionWith(optional<Rect> b). See http://www.boost.org/doc/libs/1_41_0/libs/optional/doc/html/boost_optional/… I'm willing to refactor to remove OptRect. Any objections? - Alex

Getting an Inkscape generated PDF in CMYK
by JiHO 10 Jan '10

10 Jan '10

Hello everyone, I have a colour document I want to get printed by a print shop. It is a monochrome (shades of the same hue with different lightness/saturation, basically all brown) fully vector document. Currently I have the SVG exported in PDF. The print shops want a CMYK PDF, as expected. They don't seem too smart (insist on using photoshop on the PDF, don't pay much attention to the superposition of recto and verso, etc.) so I would like to do as much as possible myself. However, even with a CMYK document I guess they would still need to do a CMYK to CMYK conversion between my CMYK profile and the one of their printer. Would this be any better than going straight from my RGB to their CMYK? If I do need to convert in CMYK, I explored the possibilities. The SVG does not import correctly in Scribus so this is out of the question. I have Adobe Acrobat, which looks like it can do the conversion on the PDF. I am just not sure what it assumes as a starting colour space, if any. What would the knowledgeable people on this list advise as a workflow to get an Inkscape generated PDF in CMYK? As a related note, what is the advised workflow within Inkscape? I have a display and proofing profiles set in the preferences (NB: Jon, does the "Retrieve profile from display" works on Mac? It does not inactivate the drop down menu when checked at least, while it looks like it should.). My understanding of the 0.46 release notes is that as soon as a display profile is set, it is used, and clicking the indicator at the bottom-right corner turns soft proofing on, using the specified proofing profile. Am I right? What part of all this is currently retained in the SVG? in the PDF? Sorry for the numerous questions. I would like to get this one right. Thanks in advance, JiHO --- http://maururu.net
