Warnings: compiler flags
by Johan Engelen 20 Mar '14

20 Mar '14

Hi all, Can someone tell me where to add compiler warning/error flags for Makefile users? (On Windows, I know) Am going to slowly activate erroring on specific warnings. Thanks, Johan

It happens that when libUEMF is used in Inkscape glib is available, but that is not the case in other situations. Regards, David Mathog mathog@...1176...

Status of Inkscape 0.91 Release
by Bryce Harrington 20 Mar '14

20 Mar '14

2. Chill. DONE Development focuses on wrapping up DONE Disable features that aren't finished Identify 'make distcheck' issues Identify any critical OSX/Win32 packaging issues Identify remaining writing needed for Release Notes. DONE Regressions Bug Hunt: 500 points Update tutorials and other docs Can you help me identify where we are with the remaining items in the above list? 1. I ran 'make distcheck' and hit an error: CXX event-log.o ../../src/event-log.cpp:11:33: fatal error: util/signal-blocker.h: No such file or directory compilation terminated. There were also a bunch of errors in libcroco, that'll all need cleaned up. 2. I have zero insights into OSX or Win32 packaging. Can someone give me a low-down on what the current state is with these? Do we have all the dependency changes covered? Do the packaging scripts still work and produce a viable binary? Any other issues folks are worried about? (I do not want to find ourselves blocked from releasing due to Win32/OSX packaging problems, so if there are any I want to get them on the radar now, so we don't move forward from chill or freeze until they're sufficiently taken care of.) 3. I reviewed the ReleaseNotes a few months back and they looked really solid. Are there any areas you see where we need more attention? 4. Which features from this release need to have documentation and/or tutorials made? Is there any other tutorial or documentation work that will require tracking with the release? Bryce

Warning fix for our libcroco copy
by Johan Engelen 20 Mar '14

20 Mar '14

To the libcroco-copy maintainer, Please have a look at rev. 13173, in which I fixed a number of compiler warnings. There were some unused function arguments, and the "fix" was to assign a value to them but not use them, triggering a GCC warning. Plus it's confusing code, so I applied the "proper" fix by using a common "UNUSED" macro. Ugly, but that's C for you ;) Cheers, Johan

Warning fixes for our libgdl copy
by Johan Engelen 20 Mar '14

20 Mar '14

To the maintainer of our libgdl copy, Please have a look at rev. 13171. I fixed some compiler warnings. Look especially at the (gint) casts, because there appear to be some bugs there. The result of gint-gunit is unsigned! Cheers, Johan

UI Testing Tomorrow
by Martin Owens 20 Mar '14

20 Mar '14

Hi Guys, I'll be at SpinachCon[1] tomorrow here in Boston and the idea is to test various UI workflows. By default I'm going to use the tutorials as a fall back of things to test. But if you have certain UI workflows, especially new ones, that you'd like some data on. Please get back to me before tomorrow so I can write up the guides for the volunteer testers. Best Regards, Martin Owens [1] http://www.openmediaboston.org/content/spinachcon-wants-you-help-make-free-…

GSOC 2014 participation
by m 19 Mar '14

19 Mar '14

Hello everybody, I am an engineering student at NIEC in India .I love drawing and coding and so I wanted to make a tool/plugin for Inkscape. Here is the discription of the tool : 1.The basic idea of the tool is keep your drawing up to date in symmetry . 2.This tool will help artists make symmetrical drawings ,like they are drawing in front of a mirror/axis 3.The user can have 1 or more than 1 mirror/axis (limit to be defined) for the sketch to be duplicated on. 4.The artist will be able to draw symmetric facial images,snowflakes, kaleidoscopic patterns,characters or objects. 5.It will make existing drawings and illustrations reusable. 6.The user can describe one of the following things like the origin point where the mirror is to kept, its angle and number of mirrors/axis to be used I came up with this idea when i was drawing snowflakes for a weather app (that i discarded) and i found out that it was quite time consuming to drawing good quality snowflakes QUICKLY. Finally i would like to ask whether this idea is good for GSOC 2014 participation?I am really eager to participate this time. Thanks for your time and consideration. Regards, Marakiam

There are several classes used in the fill and stroke dialog which you could convert to C++ or improve, for example SPColorSelector and its derived classes. They are C++ classes, but they are hidden as members inside GObjects, which is confusing to novices and leads to verbose code. You could convert them to proper C++ classes that derive from the relevant gtkmm widgets. > Regards > Tomasz > > [1] https://www.dropbox.com/s/kvgjvtowpm55m5h/new_patterns_ui_2.svg > [2] http://tirania.org/pictures/hwidgets/gtk-combo-tree.jpg, > http://tirania.org/blog/archive/2008/Jun-01.html > [3] https://blueprints.launchpad.net/inkscape/+spec/named-color-swatches > > PS > > Your message was sent directly to me, omitting the mailing list.

Extension: Merge Style
by Martin Owens 18 Mar '14

18 Mar '14

Hi devs, I've committed in r13161 an extension which will take the inline styles from the selected elements, find the common values and create a new css style in the existing or new style element at the top of the document. This replaces the inline styles with a class reference. <rect style="fill:red;"/> <rect style="fill:red;"/> <rect style="fill:yellow;"/> <rect style="fill:red;stroke:green;"/> Becomes: <style> .name_of_choice { fill:red; } </style> <rect class="foo"/> <rect class="foo"/> <rect style="fill:yellow;"/> <rect class="foo" style="stroke:green;"/> I've added this into the extensions menu under Stylesheets > Merge Styles into CSS. And I decided to push it into trunk instead of just keeping it on my hard drive because it might be useful to other users. But I'd also like to sound it out too. So any issues you think, I'd love to hear. This should make it easier to make web svg I think. Best Regards, Martin Owens

GSoC proposal
by Krzysztof Kosiński 16 Mar '14

16 Mar '14

Here is what I submitted to Melange, let me know if anything else is necessary: Inkscape requires several high level path manipulation routines to implement some of its effects: - Boolean operations on paths. - Stroke-to-path conversion: given a path and stroke parameters, compute the shape of the stroke and return it as a new path. - Path offset. These operations are both available directly to the user and used as a building block for more complex effects. The current implementation uses a grid-based algorithm which rounds all coordinates to a multiple of some arbitrary quantum. This has several shortcomings - most notably it does not preserve the dimensions of the operands (see [1]). To provide a robust foundation for further feature development, this project will implement robust Boolean and stroke-to-path operations. The API will look as follows: class Path { ... void stroke(Coord width); void stroke(Coord width, std::vector<Coord> dash_array, Coord dash_offset); Geom::OptRect strokedBounds(Coord width); Geom::OptRect strokedBounds(Coord width, std::vector<Coord> dash_array, Coord dash_offset); Path &operator|=(Path const &p); Path &operator&=(Path const &p); Path &operator^=(Path const &p); Path &operator-=(Path const &p); bool contains(Path const &p); }; Operator helpers will allow developers to write code such as: Path result = path_a & path_b; Boolean operations will be implemented by copying the algorithm used by CGAL [2]. If necessary, CGAL will be added as a dependency of 2Geom, but will be hidden from users of the library (CGAL headers will not be required to build programs using 2Geom). Stroking operations will be based on the existing curve offset code for single paths available in 2Geom's offset toy. The stroke will be computed as an union of the offsets of all curves and the resulting shape will be post-processed to add joins and caps. Once the new operations are available, the Inkscape codebase will be modified to make use of them, and the current implementation from the livarot library will be removed. Additionally, the following smaller work-items will be done in the preparatory phase: - 2Geom's Path class will be renamed to Subpath, and the PathVector class will be renamed to Path, to mirror SVG terminology. - Copy-on-write functionality will be moved from Subpath to Path. - Various helper methods will be added to Path to simplify existing code. - The SPCurve class will be removed. Schedule: - before June 10: complete the items from the preparatory list, bounding box computation for stroked paths, read CGAL code and determine if adding it as a dependency is required - June 10 - June 30: final exams at my university - after June 30: implementation of boolean operations, implementation of stroking [1] https://bugs.launchpad.net/inkscape/+bug/168158 [2] http://doc.cgal.org/latest/Boolean_set_operations_2/index.html Regards, Krzysztof

Inkscape sponsorship for LGM attendees
by Bryce Harrington 15 Mar '14

15 Mar '14

Interested in meeting up with fellow Inkscapers? Thanks to generous donations to the project, we are able to provide funds to reimburse five developers up to $500 each for attendance at the Libre Graphics Meeting in Leipzig in April. Anyone in the AUTHORS file as of Feb 19th, 2014 is eligible to apply. To register, please email Tavmjong Bah, our coordinator for the event, by March 6th to get on the list. He'll let you know what position you are in the list. Then, register for the conference, enjoy your time, and save your receipts. Afterwards email copies of the receipts to Tav, who will forward them along to SFC for reimbursement. A maximum of $500 US each will be reimbursed to five attendees for travel, hotel room, and food. Note that the LGM meeting may also give partial reimbursements, so if your total costs exceed $500 they may be able to help. In addition, the board is sponsoring Tavmjong Bah to attend both LGM as a speaker and as our event coordinator, and the co-located SVG Working Group Meeting. Tav will be representing Inkscape's interests at the SVG meeting, and will be working with them on features including mesh gradients, hatched fills, and auto-flowed text. Thank you to everyone who has contributed to Inkscape in the past. Your funding has made these sponsorships possible. We've found these face-to-face meetings invaluable both for sharing ideas and as general inspiration for advancement of the project. Bryce

Careful with C-strings!
by Johan Engelen 14 Mar '14

14 Mar '14

Hi all, *Please take this to heart: be very careful when handling C-strings. And try hard to use std::string, even if it involves a bit of work / adding helper functions.* Another C-string induced memleak was added today. Actually, the change fixed one memleak, but replaces it with the same one. Fixed in r13101. How to go about things using std::string in this particular case, see for example: http://stackoverflow.com/questions/20446201/how-to-check-if-string-ends-wit… ciao, Johan

Optionally disable antialiasing - implement based on existing SVG 1.1 rendering properties?

Ideally, the user could then optionally apply this to individual objects (which may trigger bug #170356 if the objects' edges are adjacent), to groups or layers, or to the document itself, and the same effect may even be supported in other SVG renderers? AFAIU to disable antialiasing globally, these attributes could be added to top-level <svg> element: shape-rendering="crispEdges" text-rendering="optimizeSpeed" I'm not sure whether this one too: image-rendering="optimizeSpeed" <http://www.w3.org/TR/SVG11/painting.html#RenderingProperties> <http://www.w3.org/TR/SVG11/painting.html#ShapeRenderingProperty> <http://www.w3.org/TR/SVG11/painting.html#TextRenderingProperty> <http://www.w3.org/TR/SVG11/painting.html#ImageRenderingProperty> The attributes are also in the SVG2 draft: <http://www.w3.org/TR/SVG2/painting.html#RenderingHints> If implemented based on these rendering attributes, the feature should (or rather: could) also allow to control the rendering of different types separately (i.e. disable for shapes only, or for text only, or both), and maybe other text rendering modes can be added in the future (e.g. aliased with hinting for 'optimizeLegibility'). Note that support for 'image-rendering="optimizeSpeed"' has already been implemented (currently settable on import, and in objects properties for bitmap images (linked, or embedded)). b) Alternatively (based on other user requests), if the implementation stays a custom inkscape feature only: what about splitting it into a display mode (for rendering on-canvas, in the 'View' menu), and a bitmap export option which can also be used on the command line (without having to first edit the document properties via GUI)? Regards, V P.S. Personally, I somewhat disagree with closing bug #170356 based on a solution which globally disables antialiasing (for all shapes and text in the current document) - that report originally tracked an issue with a very specific aspect of antialiasing (adjacent edges); the current solution seems more like a workaround to me (disable antialiasing just for everything, including text (which - especially at smaller sizes - tends to looks bad (AFAIU due to lack of hinting) and objects not affected by bug #170356 at all). With r13144, antialiasing btw returns if an object (or group) has a reduced object (aka global) opacity, or uses a filter effect, for clipped or masked objects and probably other special cases.

Hi devs, I was just making some art and noticed I couldn't select any fonts in the latest ppa build. Is this a known problem? Martin,

If you have your own branch on which you collaborate with a few users, you can just use a checkout. Instead of saying "bzr branch lp:path/to/branch" at the start, say "bzr checkout lp:path/to/branch". Then everything you commit will appear on Launchpad immediately, and to update you can simply say "bzr update". You can also say "bzr bind :push" to convert an existing non-diverged branch into a checkout. Regards, Krzysztof

Font weight variants - bug 167353
by Krzysztof Kosiński 12 Mar '14

12 Mar '14

Hello all There is a long standing bug about font variant selection. I can't seem to reproduce it on Ubuntu 13.10 - selecting a different variant with a non-default name works correctly. Can someone update the bug with up-to-date instructions on reproducing? Given that other comments suggest that the bug is specific to the interactive display, I think it could be fixed by changing the code in the display tree to be equivalent to the one in the Cairo renderer used by PDF export. Currently they use completely different operations to display the text. Regards, Krzysztof

Ungrouping switches
by Krzysztof Kosiński 12 Mar '14

12 Mar '14

This is related to https://bugs.launchpad.net/inkscape/+bug/1001756 The ungrouping code was treating svg:switch like groups. Is this the correct behavior? (For the time being, I modified it to ignore groups.) We don't use svg:switch in Inkscape-generated SVG at the moment, so this is relevant only to externally authored content. Regards, Krzysztof

Fwd: GSOC 2014 - New patterns/paint servers UI

Some comments on the UI mockup: 1. "Contour" should be "stroke" 2. The palette behavior should be reused in this dialog. Normal click should apply the pattern to fill and Shift-click should apply to stroke. 3. The way the pattern icons are supposed to "jump" when one of them is selected is very bad. 4. What is the purpose of the "transform" button? The pattern transform is specified on the object, not on the pattern, and is already editable on the canvas. This looks like a mistake. 5. I think it would be more sensible to embed the pattern preview and chooser into the existing fill and stroke dialog. > The new dialog would provide a way to browse, manage and apply patterns. > Some basic support for grouping patterns into collections would be provided. > By dragging a pattern and dropping it on an svg object or on Fill and Stroke > dialog, a user could apply it.

I'm not convinced that this is the way to go. However, we definitely need a new UI concept for editing distinct "areas" of the document (e.g. separate pages, patterns, masks, and so on). It would be ideal if the concept you invent could eventually be reused for the other use cases. > An alternative to "patterns" dialog would be to implement a general "print > servers" dialog, enabling to manage, besides patterns, named colors, > gradients and hatches.

"Paint servers" is technical jargon and should not appear in the UI. "Swatches" or "Paints" is better. I think a generic dialog for all paints would be better than a dialog only for patterns. > Please tell me what do you think about this idea. Is it suitable as GSOC > project? Which alternative is better in your opinion? The proposal looks sensible. If you don't have too much experience with the Inkscape codebase, I think you could limit the proposal to providing the pattern preview in the fill and stroke dialog and converting a few things to C++ along the way.

Help with bzr
by Jabiertxo Arraiza Cenoz 11 Mar '14

11 Mar '14

Hello, I have a question to use bazaar: I'm working on a custom branch in a launchpad team, I'm owner. I have a local repository, using like: *bzr merge from Inkscape trunk *?bzr resolve *bzr commit -m "Update to trunk" *change code in my local branch.. *bzr commit -m "Some changes to branch" *bzr push to the branch in the team After now, never have problems but now there is more people working on, and I want to know whats the way to be sync. For example if I merge from the team like this: *other user PUSH some code to the branch in the team *bzr merge from branch in the team *bzr commit -m "Adding other user updates" *bzr push to the branch in the team This remove the other user push/es and be replaced well, but for my user, removing other user pushes. I think this is wrong. Any body know a good way to archive ok? Thanks in advance, and sorry if not enought clear.

Inkscape Swag
by Martin Owens 11 Mar '14

11 Mar '14

Hi Everyone, I'll be attending SpinachCon and representing Inkscape to do some user testing and I was wondering if we have any swag like stickers which might be good for users who take time to test things. Do any of you know where Inkscape swag might be gotten from? Best Regards, Martin Owens
