Windows packaging for 0.49
by Josh Andler 31 Jul '11

31 Jul '11

Hey All, I have a couple things I'm going to look into for 0.49. One thing is offering msi installers. The other is potentially providing a native 64bit version as well. There was recently a discussion, I believe on the gtk list, about using OpenSuse's build service to compile windows binaries. I checked, and indeed there is a 64bit version of Inkscape compiled for Windows as well as all necessary 64bit libs (I have yet to test them, but it's planned for this weekend). It's a little different since they're packed in RPMs and use an "interesting" directory structure. However, I bet with a little bit of scripting we could automate all aspects of this and possibly add in re-packaging it and pushing automated nightly builds to modevia. Thoughts? Cheers, Josh

Rendering bug with some filters (Cairo?)
by Ivan Louette 30 Jul '11

30 Jul '11

I found a rendering bug in The two Inkscape Cairo versions I use (10404 and 10514) with the "Non realistic 3D shaders" filter effect. It's linked with the first "Composite" in the tree and particularly visible when it's set on "XOR" (which is often used in thsi kind of filter). Inkscape 0.48.1 render them correctly. I send some examples and the filters file to test. Thanks to take a look at. ivan

occasional artifacts on Zoom In (inkscape-trunk)
by SorinN 30 Jul '11

30 Jul '11

Ubuntu 11.4 ( with cairo-1.11.2 ) radeonHD 5570 with catalyst 11.6 steps to reproduce : 1) open a new file 2) draw a rectangle or another figure 3) zoom-in - before the mouse release the artifacts occasionally will occur - probably is just because of ATI / AMD drivers http://www.cstefu.com/img/artifacts.png -- Nemes Ioan Sorin

Adding node with ctrl+alt
by Johan Engelen 28 Jul '11

28 Jul '11

Hi all, When you add a node to a path using the nodetool with ctrl+alt, it maintains the selection of previously selected nodes. This is extremely annoying: consider adding a node, moving it a bit, adding a new one, wanting to move it but then the old one also moves... (thanks Alessandro for pointing this out to me). Is this desired behavior? If so, is it ok to add an option to reset selection to only the newly added node? Ciao, Johan

Raw penstroke handling
by John Allsup 28 Jul '11

28 Jul '11

Hi, I'm new to this list and haven't been using Inkscape for long, but I think this one belongs on this list. I asked elsewhere whether it was possible for Inkscape to record, edit and playback penstrokes through the calligraphic tool, and the answer was a negative one. So I went away and thought about it. I wrote a quick C header (at http://chalisque.com/c/penstroke/stroke.h) to illustrate the idea. It's quite short at present, just capturing the abstract idea, so I've included it at the bottom. (I'm not interested in compiling it yet, so don't comment about the //comments if these are not legal in C yet.) The thinking took me beyond Inkscape, but its use in Inkscape (and possibly GIMP) was its raison d'etre, so I think Inkscape developers are probably worth talking to, but consider this. Suppose there was a generic (at the level of GNOME or Unity or whatever) method to capture and manipulate raw penstrokes which could be analysed to produce other slightly different penstroke objects and which could be saved, loaded and passed from application to application. I could draw something in Inkscape, take the raw penstrokes that were used as input, pass them to GIMP and run it through one of GIMP's brushes to produce a bitmap image that could then be re-imported into an Inkscape document (so as to be able to efficiently use GIMP's filters and brushes) etc. For now I am just asking some of you to consider the possibilties and think ahead to the possibility of these facilities being available (whether Linux only or everywhere Inkscape runs I'll leave to other discussions.) Have a think, Cheers, John -----[ stroke.h ]----- // value typedefs typedef float penstroke_real; typedef int penstroke_index; typedef int penstroke_dim; // function pointer typedefs typedef (penstroke_real *)(*penstroke_position_function)( void *data_ptr, penstroke_real t); typedef (penstroke_real *)(*penstroke_parameter_function)( void *data_ptr, penstroke_real t, penstroke_index i); typedef (penstroke_index *)(*penstroke_indexed_parameter_function)( void *data_ptr, penstroke_real t, penstroke_index i); // shorthand typedefs typedef penstroke_position_function pst_posf; typedef penstroke_parameter_function pst_paramf; typedef penstroke_indexed_parameter_function pst_iparamf; typedef penstroke_dim pst_d; typedef penstroke_index pst_i; // struct typedefs typedef struct penstroke { penstroke_dim dimension; penstroke_position_function position; penstroke_dim paramter_dimension; penstroke_parameter_function parameter; penstroke_dim indexed_parameter_dimension; penstroke_indexed_paramter_function indexed_parameter; void *data; // arbitrary data for the functions to handle.) } penstroke; // Note that the number of dimensions through which the penstroke runs is not specified. // this allows for a (time,x,y) and (time,x,y,z) type dynamic strokes to be expressed. penstroke *penstroke_create( pst_d ptd, pst_posf pt, pst_d pad, pst_paramf pa, pst_d ipad, pst_iparamf ipa, void *data_ptr); penstroke_real *penstroke_get_position(penstroke *p, penstroke_real t); penstroke_real *penstroke_get_param(penstroke *p, penstroke_real t, penstroke_index i); penstroke_index *penstroke_get_iparam(penstroke *p, penstroke_real t, penstroke_index i); -- [::- John Allsup -::=::- http://chalisque.com -::]

libgdl again: opinions please!
by Alex Valavanis 25 Jul '11

25 Jul '11

Hi all, To follow up our recent discussions about building against an external copy of libgdl (https://launchpad.net/bugs/792115)... I have played with the code, and here is a summary of my findings: The Inkscape fork of GDL is branched from gdl-0.7.7, which was released a loooong time ago. There have been very substantial upstream changes/bug-fixes since then. In particular, our version uses lots of deprecated/obsolete GTK calls, meaning that Inkscape will fail to build against GTK 3. We therefore need to fix this issue fairly quickly. Our fork of GDL introduces a couple of new features. Here are the main ones I can see: * Focus switching between docked dialogs, with tab/arrow-key bindings * Ability to create a docked dialog using a pixbuf icon. I have forwarded a patch upstream to GDL (https://bugzilla.gnome.org/show_bug.cgi?id=652248) asking if they would be able to merge any of our changes. The upstream developer was very supportive and helpful, and had a few queries. However, I'm not an expert on GDL/GTK and I'm not in the best position to comment. I see three options for fixing the problem: 1) Build against external GDL right away --- This should be easy to do, but we'd lose our changes for a while. However, I'm not sure any of the changes represent essential Inkscape design features and we'd be able to reimplement them when they appear in the upstream API. 2) Merge our changes into upstream GDL 2.30 and copy this into the Inkscape code --- This will take a bit of fiddling around, and it still relies upon us working with forked code. I have managed to make a branch of inkscape with gdl-2.3.0+changes that compiles and runs, but it is buggy (no colour switching and some graphics glitches). Unfortunately, my GTK knowledge is not good enough for me to do this by myself. If anyone is able & willing to help, I can push the new branch. 3) Don't fix it yet! --- Wait until upstream have implemented all the changes (in GDL >=3.1.1) and then switch over. However, we have no guarantee of how long this will take, and we will be unable to support GDK+ 3 builds until we switch! Please let me know what you think! AV

Page border display uncomplete
by Ivan Louette 25 Jul '11

Rev 10495 on kubuntu When page shadow is disabled the horizontal line at the bottom of the page border disappears at launching. If you disable and reactivate page border it comes back. But if you scroll this line ouside the document window (up or down) it disappears again when you scroll back. ivan
