Mac OS X Build 0.48.4 RC1
by Valerio Aimale 16 Sep '13

This is a good build that is close to being a release: For Mountain Lion http://rapidshare.com/files/4204947016/Inkscape-r0.48.4-r9943-10.8%2B-x86_6… For Lion: http://rapidshare.com/files/3505176415/Inkscape-r0.48.4-r9943-10.7%2B-x86_6… - the menu should be all working but the "Open Recent" submenu. No matter which item is selected, the top open is always opened. This is a bug between gtk/gtk_recent_menu_manager() and gtk-mac-integration. Needs more analysis, not an easy fix. - Quit, About and Preferences menu items moved under the app menu. - python should be fully working now on Lion and Mountain Lion - uniconvertor/sk1libs installed and fixed The sk1libs/utilsfs.py line return ['/'] really should be return ['/System/Library/Fonts', '/Library/Fonts', os.path.expanduser("~/Library/Fonts")] - no more noise on the terminal stderr - bunch of improvements and changes in the build system

Hi, this week I ironed out all crashes I could find and fixed the libavoid routing I recently broke. I fixed loading/saving of documents containing connectors and points (yay!) and back-ported the parts of the code that would need C++11 to compile to pre-C++11. Tomorrow I will test more complicated libavoid routing and make a plan for object inclusion/exclusion selection and make a test build to verify everything works on a clean system followed by a few test runs inside valgrind. Remaining TODOs are icons for the toolbar buttons, undo handling, some more advanced point manipulation functions (mainly putting points in groups/taking them out of groups) and, finally, rebasing everything onto upstream. And there is the mystery of the lost cursor, but I think I'll figure that one out. The current code can be found at [0].

Re: [Inkscape-devel] Post-merge EMF work

For now I'm going to put it in a separate directory, so that it can be easily upgraded from the upstream version. I'll put the symbol font conversion routines in the same directory, since this functionality is closely related to EMF output. I don't know what to do with 'libTERE' yet - I assume you mean the text_reassemble.[hc] files in src/extension/internal. By the way, it seems you haven't added yourself as an author to the EMF output files which you significantly changed. Can I add your name and e-mail there? Regards, Krzysztof

Hi, this week I changed the SPPoint selection to use Inkscape's normal selection mechanics instead of the control-point-selection.cpp. This has the advantage that selecting points and connectors at the same time is not quite as bad a hack as it would be otherwise. Doing this I introduced a new signal for selection/deselection in SPObject. I also changed the UI a lot to make it possible to reconnect connectors. SPPoints are now created by shift-clicking into the document while the selection is empty. If the selection is not empty, shift-click toggles the selection of the object under the cursor. Control-click should work as expected with groups. Connectors are terminated by clicking on the end point or somewhere in empty space (in which case a new SPPoint will be created on the clicked location). Sometimes stray points still appear because I have not yet found out how to delete SPPoints without crashing Inkscape. I am working on that. Connector deletion appears to work now. SPPoint deletion still has its issues. After deleting a SPPoint, Inkscape crashes with ominous memory corruption errors. I was unable to find the cause of that so far. I will push a commit later that allows easy reproduction of this. Sebastian

DialogScript message
by mathog 29 Aug '13

29 Aug '13

Just built branch lp988601 for the first time since Kris merged in changes from Trunk on 8/16. It seems to work fine, but there is a new message at the beginning: Unable to find: DialogScript ** (inkscape:14139): WARNING **: Unknown verb name: DialogScript Is that something old that has been partly removed, or is it something new that has been partly implemented? On the bzr update there was a warning that src/extension/script could not be removed because it was not empty. Related to this message? Thanks, David Mathog mathog@...1176...

[Inskscape-devel] [Recolor] Good News after long
by Arshdeep Singh 29 Aug '13

29 Aug '13

Hi all, I was able to spot the reason for the crashes. It was the type-casting that was causing a pointer nullification. With a few modifications I was able to fix that I got to render the nodes onto the wheel. Its just time to play with signals and xml stuff now. :) Here's a screenshot for interested folks: [image: Inline image 1] -- Arshdeep Singh Third Year, Computer Engineering Delhi Technological University Ph: +91-9654115614 https://sites.google.com/site/adsingh1729/home

Rethinking revision 12471
by mathog 28 Aug '13

28 Aug '13

I recently became aware of revision 12471, and overall, I am afraid that the way in which it was implemented is detrimental to the readability and future maintenance of the Inkscape code. Presumably the underlying function it implements is to allow changes in the ratio PX/IN, and other units of measurement, and I have no issue with that goal. However, prior to 12471 all of the unit relationships were neatly set up in a set of defines in src/unit-constants.h which defined things like PX_PER_IN which were used elsewhere in the code. These evaluated to static values, and the new ones do not, but that does not negate the usefulness of the define. 12471 removes all of these defines and makes substitutions throughout the code where PX_PER_IN is replaced by Inkscape::Util::Quantity::convert(1, "in", "px") My first criticism is that the new quantity is at first glance, indeterminate. Is it converting IN to PX or vice versa, what does "1" do? My second criticism is that eliminating the defines results in hundreds of substitutions in 12471 that are entirely unnecessary. All that was required was to change the defines in src/unit-constants.h, for instance from #define PX_PER_IN (PT_PER_IN / PT_PER_PX) to #define PX_PER_IN Inkscape::Util::Quantity::convert(1, "in", "px") after which virtually no changes elsewhere in the code are required. By doing that, the existing and relatively clear code, like: p0[X] = (p0[X] * IN_PER_PX * dwDPI); need not become the obfuscated (to my mind) form: p0[X] = (p0[X] * Inkscape::Util::Quantity::convert(1, "px", "in") * dwDPI); Before 12471 PX_PER_IN already evaluated to a complex expression, and the whole point of the define was to let the compiler handle that mess and only present to the programmer a short easily understood term. 12471 is a step backwards in this regard.

Fwd: Modifications to RecolorWheelPrivate

2013/8/27 Arshdeep Singh <moduli16@...400...>: > I added: > new (&(priv->nodes)) std::map<std::string,RecolorWheelNode>(); > to recolor_wheel_init (RecolorWheel *wheel) . > > Honestly I have never seen this style of code, so I really don't understand > what it does. The good news is it does get to run the dialog box of 'Recolor > Artwork' i.e. no error while the dialog is loaded, but the moment I draw a > shape (active selection) the application crashes. This 'style of code' is known as 'placement new' and it calls the constructor of an object with an explicit 'this' pointer. It needs to be used when memory for an object is allocated from a different source than operator new. In normal C++, placement new is rarely used, because objects are typically allocated and constructed at the same time with operator new. However, if you allocate memory from a different source (in this case from GObject), you need to call the constructor yourself. http://en.wikipedia.org/wiki/Placement_syntax > Also my init function looks like this (for a quick browse, if needed): > > static void > recolor_wheel_init (RecolorWheel *wheel) > { > > RecolorWheelPrivate *priv; > > priv = G_TYPE_INSTANCE_GET_PRIVATE (wheel, RECOLOR_TYPE_COLOR_WHEEL, > RecolorWheelPrivate); > > wheel->priv = (RecolorWheelPrivate*)priv; > priv = (RecolorWheelPrivate*)wheel->priv ; What is the point of the last line? Why the casts? They are unnecessary. > What I don't undersytnd is how to initilaize a static object. > RecolorWheelPrivate has other static members like : What exactly do you mean by "static members"? The structure you provided does not define any static members. > gdouble h,s,v don't need explicit initializers. Why so ? Is it that the only > map object requires an explicit initilization. If so, why ? 'gdouble' is a primitive type (a typedef of 'double') which doesn't have any constructors. GObject zeroes memory by default, so if you don't assign to h, s, v they are left as all zeroes, which corresponds to the double value of 0.0. Regards, Krzysztof

XDG Templates
by Martin Owens 28 Aug '13

28 Aug '13

I was reviewing the templates work by Jan Darowski and it got me thinking about the FreeDesktop.org XDG spec; it has a provision for a templates directory that we should be using instead of (or as well as) ~/.config/inkscape/ which is hidden from the user. This only applies to FreeDesktops/XDG complient desktops. But it would be useful. http://freedesktop.org/wiki/Software/xdg-user-dirs/ Example: XDG_TEMPLATES_DIR="$HOME/Templates" Thoughts?
