Question about SPItemCtx
by Alex Valavanis 18 Mar '13

18 Mar '13

Hi All, I'm a bit confused about the way that SPItemCtx is implemented. I have a few questions: SPItemCtx is defined in src/sp-item.h as follows: /// Contains transformations to document/viewport and the viewport size. class SPItemCtx { public: SPCtx ctx; /** Item to document transformation */ Geom::Affine i2doc; /** Viewport size */ Geom::Rect viewport; /** Item to viewport transformation */ Geom::Affine i2vp; }; As far as I can tell, the only place where an SPItemCtx object is created is in the SPDocument::_updateDocument() function. It is then cast to SPCtx object and sent to the updateDisplay function. Various "update" handlers then retrieve the SPItemCtx data by casting back: SPItemCtx *ictx = (SPItemCtx *) ctx; double const aw = 1.0 / ictx->i2vp.descrim(); This seems a bit weird to me... why not make SPItemCtx a subclass of SPCtx? That way, we wouldn't need to do risky reinterpret_cast<> operations. Any thoughts? AV

Seems like nothing includes the dom/svg2.h header. Can I kill it? AV

Hi I would like to update this page: Compiling_Inkscape_on_Windows I meet some error when install the TDM's GCC and compile btool. TDM's GCC needs 'Uncheck' the [Check for updated files on the TDM-GCC server] or it will always install the latest gcc Compile btool also can be done by only g++ buildtool.cpp -o tool Make sure you have correct DEVLIB_PATH and MINGW_PATH Thanks Xiangfu

What is the difficulty in adding text decorations, especially underline?
by mathog 14 Mar '13

14 Mar '13

There have been user requests for underline (a text decoration) going back years and years. Since it has not shown up I assume this means that some library Inkscape depends on cannot do this. I checked the most obvious suspects and did not find a definitive smoking gun: 1. Freetype does support underlining (both location and thickness). http://www.cs.sunysb.edu/documentation/freetype-2.1.9/docs/tutorial/step2.h… 2. SVG supports it with "text-decoration:underline". 3 Pango supports it: https://developer.gnome.org/pango/stable/PangoMarkupFormat.html 4. Cairo - not sure. (Maybe this is the guilty party?) So, is there a document somewhere which explains why Inkscape cannot underline? I looked for a while but all Google turned up were lots of threads about how Inkscape does not have underline, but not _why_ it does not. Thanks, David Mathog mathog@...1176...

GCC version checking
by Alex Valavanis 13 Mar '13

13 Mar '13

Further to bug #992124 <RFE: clang support> [1], is there any reason why we still have a hardcoded check for gcc >= 3.0 in the configure script? 1. It prevents easy use of non-gcc compilers (clang) 2. Version 3.0 is archaic, and is presumably available on every platform that could feasibly build Inkscape (i.e., other infrastructure checks in the configure script would fail, so the test is redundant) 3. Why are we specifically looking for version 3.0? If we're wanting to check for a compiler feature, there are more elegant ways of checking for this than just looking for the version number. If no one objects, I'll remove the version check. Best wishes, Alex [1] https://bugs.launchpad.net/inkscape/+bug/992124

transform inkscape:original-d into a defs + LPE
by pennec victor 13 Mar '13

13 Mar '13

Hi, Why original path are stored directly into the shape as an inkscape:original-d attribute rather than in a defs (like path-effect) ? Why is there no "simplify/smooth" LPE ? When you draw line (F6), a smooth factor is applied and a certain shape (ellipse, growing triangle) is used. If you'd like to replay different settings on the same input then you're out of luck : the original output is gone forever because the nodes are already discarded. Some we'll be able to remove the pattern along a path by going into the LPE, most will clik/drag the tool controls and ask why they can't modify settings AFTER the shape has been drawn How to submit a blue print ? Thank you for reading
