Devlibs SVN
by Krzysztof Kosiński 08 Jan '10

Hello 1. Where is Windows devlibs SVN hosted? 2. Why it contains .pyc files? 3. Why is glibmm version lower than GLib version (2.14 and 2.16 respectively)? 4. How can I get commit access? 5. Where is libxslt.pc? PS: I just installed WinXP in VirtualBox, and it works very well. I'll post a walkthrough on a wiki. This should enable more people to help with Windows problems. Regards, Krzysztof

Spray tool: code
by Krzysztof Kosiński 07 Jan '10

07 Jan '10

Hello Here are some remarks about the spray tool that are not related to its UI. Major issues: 1. The tool is very slow in single path mode - it updates XML after adding each object. XML should be updated only when the mouse is released, like in the node tool. 2. Single path mode uses sp_selected_path_union, which spams the undo stack with union operations and destroys selection. Ideally, 2Geom or livarot functions should be used directly, and if that's not possible, sp_selected_path_union_skip_undo. 3. Undo doesn't work correctly for single path mode - Ctrl+Z undoes only one sprayed copy. Less important issues: 4. Clones are created by creating XML nodes directly. Shouldn't the SP layer be used instead? 5. Cryptic pref names like "doo", "doh". 6. sp_spray_recursive has lots of parameters. 7. spray-context.cpp:554 is a crucial formula that is unreadable and undocumented. 8. Indentation in sp_spray_context_root_handler is, mildly put, unorthodox. 9. get_dilate_radius, get_path_force, get_path_mean, etc. - I don't like this. 10. random_position - data passed by non-const reference to a function that doesn't modify it. Regards, Krzysztof

I feel that Joshua (not me) summed that up nicely. It boils down to that we are an open and welcoming community. Feedback is welcomed and appreciated, and the more info you can provide, the better for experience for everyone. We don't tend to take issue unless you want to complain and suggest how we can do it better. We don't know better than you, and we won't (generally claim to) know what's right. Tell us. Everyone benefits from non-argumentative feedback. Cheers, Josh On Jan 4, 2010 11:30 PM, "Joshua L.

Re: [Inkscape-devel] spray tool: UI
by Josh Andler 05 Jan '10

I agree in principal, but I can't say that a function being "fundamental" matters as much as adding versatility to a tool, which in the end does what we want to do... empower the user. I think we should hang on to it until our nightly build situation gets sorted. The best way to figure out if it's truly valuable is to get feedback from users.

spray tool: UI
by bulia byak 05 Jan '10

05 Jan '10

I haven't fully tested the functionality yet, but here are some comments on the UI. Sorry for the terseness - I do find the tool valuable, but the UI really needs some work. * The tool icon is horrible and very out of the line with the default tool icons. The Tweak icon is not stellar either. Can some talented artist suggest a replacement? * "Population" is unclear. Its tooltip does not really help. "This setting adjusts" is superfluous, just delete it, but then what remains is still confusing: "the number of items sprayed" - total number? Per click? Per mile? Per what? What does the percentage represent? Please rethink this. * "The mean of the spray action" is impossible to understand. Mean what? * "SD" is very techy, and while the tooltip expands it as "standard deviation", it is still confusing. Standard deviation of what value? Can you explain it in terms understandable to someone who has no math training and has no idea of what SD is. * The button "Some options for the spray" is a bad idea, as is the dialog it opens. We don't have separate dialogs for tool options. Each tool may have some often-used controls on the controls bar, plus some rarely-used settings on its page in Inkscape Preferences. Please try to redistribute the dialog controls between these two locations. E.g. I don't think many people will ever change the distribution from Gaussian to uniform - this choice can be moved to Preferences. The controls bar can accommodate more than you have there now - if something does not fit it will be placed in an automatic menu, so just move the least used controls to the right (but preserving some logical grouping, of course). You may also try to combine some of the options into higher-level, coarser but more user-friendly preset-like options, such as a single "Scale randomization" slider instead of min/max values. (And for cursor, the Width value seems a duplicate of the controls bar's Width slider.) Code-wise, the file spray-option.cpp contains some leftover bits from Alignment dialog (e.g. "remove overlaps" undo comment - and why do you need to make undo commit at all in this dialog?!) and some French comments that need to be translated. -- bulia byak Inkscape.

Hi, While building revision 8938 I saw this: In file included from extension/execution-env.cpp:27: ./util/glib-list-iterators.h: In member function ‘T* const& Inkscape::Util::GSListConstIterator<T*>::operator*() const [with T = SPItem]’: extension/execution-env.cpp:61: instantiated from here ./util/glib-list-iterators.h:47: warning: dereferencing type-punned pointer will break strict-aliasing rules CXX extension/init.o ^Cmake[2]: *** [extension/init.o] Interrupt make[1]: *** wait: No child processes. Stopping. make[1]: *** Waiting for tasks execution end... make[1]: *** wait: No child processes. Stopping. make: *** [all] Error 2 The compile messages were actually in RU, so I did 'LC_ALL make' and for some reason the compilation didn't break there again and is likely to be completed this time. Any ideas? Alexandre
