October 2013 - Inkscape Devel

02 Oct '13

i started a new thread, even though this stems from the same task that made me start the previous thread (hack-tweaking a filter) Is there a way to rasterize an object or a selection in inkscape? That might also accomplish my goal — I could then apply raster color manipulations... currently, that's impossible, if my gold-splatter is in vector form. (AFAICT)

Inkscape 64-bit on Windows
by Partha Bagchi 01 Oct '13

01 Oct '13

I finally managed to build a 64-bit version of Inkscape 0.48.4 on Windows. I am pretty excited about the build. :) My build environment is Windows 7 64-bit, mingw-gcc 4.8.1 building x86_64-w64-mingw32 packages. One big problem I am having is that some of the icons on the application are missing! I checked all the bug reports and only see a similar issue with Ubuntu Unity. I am convinced the problem is with the path that Inkscape is seeing. When I divert all stdout to file, I see the following: ________________________being log_______________________ ** (inkscape.exe:4148): CRITICAL **: Inkscape::XML::Document* sp_repr_read_file(const gchar*, const gchar*): assertion 'Inkscape::IO::f ile_test( filename, G_FILE_TEST_EXISTS )' failed ** (inkscape.exe:4148): WARNING **: Unable to read keys file I:\oss-dev\msys\opt\inkspace\bin\/opt/inkspace/share\share\keys\default.xm l ** (inkscape.exe:4148): WARNING **: Null pixbuf for 00000000037DFA60 [I:\oss-dev\msys\opt\inkspace\bin\/opt/inkspace/share\share\icons\ remove-color.png] (inkscape.exe:4148): GdkPixbuf-CRITICAL **: gdk_pixbuf_get_width: assertion 'GDK_IS_PIXBUF (pixbuf)' failed (inkscape.exe:4148): GdkPixbuf-CRITICAL **: gdk_pixbuf_get_height: assertion 'GDK_IS_PIXBUF (pixbuf)' failed (inkscape.exe:4148): Gtk-WARNING **: Could not find the icon 'object-visible'. The 'hicolor' theme was not found either, perhaps you need to install it.

Can anyone help? If you need more information, please let me know. Everything is working otherwise! Thanks in advance, Partha

VisualBounds for filter effects
by Martin Owens 01 Oct '13

01 Oct '13

Hey Devs, I've just committed a fix for that darn disappearing text and other items. The culprit was a blank _item_bbox, the code for _item_bbox was very sparse and looking back to the history of where it comes from shows that Niko Kiirala introduced it back in r3505 (2007) to improve filter effect handling when transformed. What I've done is stripped it out and replaced it with the _bbox used for all the other operations. This means the bounds for the filtering process won't be different for the bounds during other parts of the process. See revision 12528 for the gory details. What I should be sure of is what Niko was trying to do and if Ted Gould (r6891) or Krzysztof Kosiński (r10347.1.21) spotted anything as they were refactoring the code. Please do test trunk for issues surrounding filters and transforms. I'd like to make sure fixing this issue doesn't introduce another. Best Regards, Martin Owens

Memory Huzzah
by Martin Owens 01 Oct '13

01 Oct '13

Dmitry Kirsanov committed 16 memory fix revisions last night and I wanted to give a hearty huzzah. I know I've not been great at spotting memory problems, so having someone go through code and clean up these issues is really reassuring to me. Thanks Dmitry! I really appreciate your work. Best Regards, Martin Owens

Packaging of bitmap downscaling fix
by Bryce Harrington 01 Oct '13

01 Oct '13

I've posted to my ppa packages (for Ubuntu 12.04) of newer pixman and cairo with the downscaling fix, and a inkscape-trunk package built against these. https://launchpad.net/~bryce/+archive/backports/+packages [Installation for Ubuntu 12.04] 1. sudo apt-add repository ppa:bryce/backports 2. sudo apt-get update 3. sudo apt-get install inkscape-trunk # This will also pull in and install newer cairo and pixman 4. /usr/bin/inkscape [Test Case] I've verified this fixes the bug, using the following test case: 1. Draw some horizontal, vertical, and other angled lines, black stroked, 1 unit wide. 2. Export selection to PNG. 3. Delete the drawn lines from Inkscape 4. Import the PNG we just created, embedded. 5. Drag the upper right corner to resize the embedded PNG Broken Behavior: The lines will blink in and out irregularly as you scale the image down; at a certain small scale the whole image will vanish. Fixed Behavior: The lines shrink in size quite smoothly, becoming fainter and fainter grey until you hit a scale that they fade out completely. The pixman package is simply the current Ubuntu 13.10 package (release 0.30.2), rebuilt for 12.04 with no changes. The cairo package is the current Ubuntu package (release 0.12.16), with the downscaling patch applied via the packaging. The inkscape package is just today's snapshot I took from the Inkscape Trunk ppa, with the cairo version requirement changed in debian/control so that it will pull in Have I missed anything? If no one raises an objection, I will upload the pixman and cairo packages to the Inkscape trunk and stable PPAs for Ubuntu 12.04, 12.10, 13.04, and 13.10, and commit the debian/control dependency version change to trunk. I believe that should appropriately solve this bug for all Ubuntu users. Bryce

It seems to be working with +cnt now. Maybe the settings needed time to sync somehow. Thanks for keeping on it Bryce. I think we got it working. I may still change the web client in use though, I was reviewing the linked and would appreciate your thoughts. Martin,
