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?

> revno: 13144 > fixes bug: https://launchpad.net/bugs/170356 > committer: Krzysztof Kosiński <tweenk.pl@...400...> > branch nick: trunk > timestamp: Thu 2014-03-13 05:45:38 +0100 > message: > Provide a toggle in the document properties to optionally turn off > antialiasing for display and export. > Fixes a nearly 10 year old bug #170356 Questions related to rev 13144 (just curious): a) Why not implement such a feature based on existing SVG 1.1 rendering instructions (instead of a custom inkscape attribute of <namedview>)? 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
