Hi. Im using style dialog, and couldent change inline atributes and inside SVG style defined css selectors. First one only allow delete atributes and second one only alow add atribute but couldent add value. Im in Inkscape 0.92+devel (a113f4663e, 2017-09-05). Im thinking on move part of the "Meassure Segment" code to be handled by CSS Style Dialog. All the best, Jabier.

Re: [Inkscape-devel] [Inkscape-user] the Scale setting and Display units
by Tyler Durden 21 Sep '17

Greetings all, A universal default.svg with units px and scale=1 provides a simple single solution to a number of issues: - Resolves broken extensions and features like symbols and outset/inset, etc. - No need for users to consider scale, they just set the display units and work. - No need to tailor localizations with in/96, mm/3.77953. - Fewer bug reports for scale and localization issues. - Neophytes are less likely to abandon Inkscape as confusing or complicated. That's a lot of benefit, for what could be relatively little effort. Like with any graphics or CAD application, users should be familiar with setting document units when starting to work. This is the most basic of best-practices. Even making a template is not difficult, but a button/tool to save the current document as a template would be very handy. Regards, TD

Oh, I didn't know about these templates! However, I think it's better for users to know how to use the interface, rather than use a template which only sets up the units, and not the page size (unless you happen to want an A4 page). I'm not clear what you mean by this: > The one thing you cannot do, however, is modify the document units after Inkscape has opened the startup file. If you know how to change the units (as I've just learned how to do it correctly) can't they be changed? Or do you mean that the user would have to save a new template if they change the units? I'm just writing the new FAQ item right now, so I'll include this info about the templates too. But need to understand that last statement (above). Thanks Alvin :-) -----Original Message----- From: alvinpenner Sent: Wednesday, September 20, 2017 6:29 AM To: inkscape-user(a)lists.sourceforge.net Subject: Re: [Inkscape-user] the Scale setting and Display units It may be worth mentioning that you can choose the document units that you prefer when you start up Inkscape. If you use the startup template file C:\Program Files (x86)\Inkscape\share\templates\default.svg (which is the default), then you will find that the document units are mm. You can confirm this by drawing a rectangle that has the width of the full page and then using the XML editor to confirm that the width has been expressed in mm. A typical example would be <rect style="..." id="rect10" width="210.91072" (should be 210, my hand was shaky) height="88.446426" x="0" y="0.66666663" /> If you prefer to use px as the document units, then use the template file C:\Program Files (x86)\Inkscape\share\templates\default_px.svg. In this case if you draw a rectangle that has the full width of an A4 page you will get: <rect style="..." id="rect18" width="797.14288" (should be 793.7007, which is 210mm expressed in px) height="357.14285" x="0" y="2.519685" /> If you prefer to use pt as document units, then use the template file default_pt.svg If you want to permanently modify the startup units, then copy a file like default_pt.svg to overwrite the file default.svg. (after first making a backup, just in case.) The one thing you cannot do, however, is modify the document units after Inkscape has opened the startup file. hth, Alvin -- Sent from: http://inkscape.13.x6.nabble.com/Inkscape-User-f2857977.html ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Inkscape-user mailing list Inkscape-user(a)lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/inkscape-user

Oh, well if that's the only reason, I would suggest going back to px for the native user units! It looks to this non-tech-oriented user like using mm for the native units is making these things much more complicated (not to mention confusing) than they really need to be. Is there any reason why I can't make a feature request in LP, to revert to px? Like is there some other reason for the change, or we're already planning to revert, or ??? I know it might or might not happen. But really, just to make the default doc match one single template -- this really is imposing a great deal of confusion for many users!

I think it's because the default template is A4 so it sort of made sense to use millimeters since A4 is defined as 210x297 mm² -- Mc ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Inkscape-user mailing list Inkscape-user(a)lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/inkscape-user

Re: [Inkscape-devel] Blur branch
by Yale Zhang 19 Sep '17

Vlada, good to hear from you again. It's very unfortunate I didn't do more to get my vectorized blur code merged especially when it was 99% done. It was reviewed and the main complaint was it didn't compile for i686. That could've been done easily, but there was another problem I realized which was how to handle vector remainders without reading past the end of an array, which could cause a crash (but with low probability). Let me wrap this up over the next few weeks if my schedule permits. Jabier, are you talking about my branch https://code.launchpad.net/~simdgenius/inkscape/inkscape or another one. There was a proposal a long time ago about approximating blur as 3 sequential box filters. You can still do that, but you would still need a version with higher accuracy for the best rendering mode. -Yale On Mon, Sep 18, 2017 at 12:47 PM, Jabier Arraiza <jabier.arraiza@...2893...> wrote: > Hi Vlada. > > Thanks for the reply, Please could you upload the patches to gitlab to > be sure the code not be lost?

Generic Auto Updater for Inkscape on Windows
by Victor Westmann 18 Sep '17

18 Sep '17

Hi everyone, I was just wondering if this is interesting for Inkscape project on Windows platform. The website of the project is here: http://wingup.org Text extracted from the homepage of GUP: "WinGUp is a Generic Updater running under Windows environment. The aim of WinGUp is to provide a ready to use and configurable updater which downloads a update package then installs it. By using cURL library and TinyXml module, GUP is capable to deal with http protocol and process XML data. Originally WinGUp was made for the need of Notepad++ (a generic source code editor under MS Windows). During its conception, the idea came up in my mind : if it can fit Notepad++, it can fit for any Windows program. So here it is, with LGPL license to have no (almost not) restriction for integration in any project. Being LGPLed, WinGUp can be integrated in both commercial (or close source) and open source project. So if you run a commercial or open a source project under MS Windows and you release your program at regular intervals, then you may need WinGUp to notice your users the new update." I find it very convenient to be able to update notepad++ by clickinh on "?" > "Update Notepad++". I am aware that in Linux and MacOS environments updates are a more automated task and usually happen in the shell or CLI side of things... but I would just like to suggest this and collect the feedback on the possibility of this feature. Thanks everyone and have a great day! --Victor Westmann

Sorry for the delay. I think I'm getting it :-) Now, more or less understanding "user units", I'm back at #3 of your first reply. And here in the middle of that paragraph....I think....is the answer I need. > (temporarily set display unit to px, set scale to 1, put display unit back to whatever you need), So when someone needs to change the Display units, so that their drawing is as close to real world size as possible, do this: 1 -- set the desired Page Size and units (this sets the viewBox, right?) 2 -- temporarily change Display units to px 3 -- change the Scale to 1 4 -- change the Display units to the desired unit 5 -- the Scale will automatically change to the appropriate value 6 -- leave everything else alone If that's correct then 1 -- I'll make a new FAQ item for it (if no objections) - perhaps link to Marc's article about it - or is there a wiki page for it? 2 -- I'm really thinking Inkscape needs to do all that internally. I think users should be able to simply select the unit they want, the page size they want, and Inkscape does the rest. May I make the bug/feature report, or is it already planned or requested? If that's not correct, please tell me where I'm going wrong. Oh, one last question. > If you only measure your stuff with the display units (and do not use units in the code, it should not matter (tools "should" take the scale into account, and if some do not it's an bug Do you mean to say that it's possible some tools are not respecting the Scale? Or is that more of a theory.

The "outside coordinate system" is just the length of things upon displaying the file, assuming one respects the given "Size" of the document. "Inside" the file, everything is measured with the "inside" coordinate system. This system's unit is the abstract "user unit": your document may have a rectangle measuring 2 user unit wide and 5 user units tall, and you can tell (in the viewBox) that your complete document is the area between the point of coord (0,0) and the point of coord (20,50), in user units. They're abstract units, like when you do basic geometry in mathematics, without units; only meaning here that 2 user units wide is 10% of the document's width and 5user unit tall is 10% of the document's height. Only the additional data of the "Size" can tell you what the total height is in the "outside world", hence what 10% of it (== my 5uu of height) are worth. Now, the units *inside* the file (like the "cm" in my post-scriptum) are only shortcuts for given, fixed, multiples of the user unit (by definition, "px" is the name of that user unit and "in" is the name given to 96 user units), but if you do not set "1 user unit is one outside-world-pixel", they're not worth what they seem. -- Mc ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Inkscape-user mailing list Inkscape-user(a)lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/inkscape-user

pressure sensitivity for Pencil tool using powerstroke?
by brynn 17 Sep '17

17 Sep '17

Hi Friends, Someone has recently posted on a forum, asking for a tool which combines pressure sensitivity of Calligraphy, freehand, powerstroke, and simplify, all in one tool. I explained we have something pretty close to that with Pencil, Triangle In/Out, with Simplify option. But it made me start to wonder. The Calligraphy tool must have been chosen for pressure sensitivity, at least in part because it can achieve variable width. Well now that we have powerstroke, I wonder if it would it be possible to give pressure sensitivity to the Pencil tool, using powerstroke? Probably a wild thought. But can't hurt to ask. Just asking if that, or something like it would be possible. Thanks, brynn
