[Bug 170049] Re: Inverted ruler co-ordinate system
@ yharrow I did create a patch to just visually change the ruler and coordinate display, but more experienced devs pointed out that this was not the best way to address the issue (see #76). Time has passed, I don't know how much work is still necessary. I'd also love to see a fix and still suggest to use the svg viewbox element for internal coordinates and visual representation or rulers. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/170049 Title: Inverted ruler co-ordinate system To manage notifications about this bug go to: https://bugs.launchpad.net/inkscape/+bug/170049/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 170049] Re: Inverted ruler co-ordinate system
@Thorjelly I wrote scripts writing out geometries at scale (in mm). For debugging and other purposes it is most useful if the numeric values in the document stay these numbers and the rulers also show the same numbers. This is not only useful for the scale but also where on the page the origin is and if it is a right-handed or left-handed coordinate system. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/170049 Title: Inverted ruler co-ordinate system To manage notifications about this bug go to: https://bugs.launchpad.net/inkscape/+bug/170049/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 170049] Re: Inverted ruler co-ordinate system
I tried looking at the svg side and I'm a little confused. How about, as a first step, modifying inkscape so that rulers and mouse pointer coordinate status use the origin that is indirectly defined by the viewbox? What about the viewbox units? Second step would be a gui to actually configure the viewbox within inkscape in a user friendly way. Finally, using those coordinates directly for new objects instead of inserting another transformation (I think this is what Krzysztof wrote in the previous post). (viewbox reference: http://www.w3.org/TR/SVG/coords.html#ViewBoxAttribute ) I played around with a hand coded svg, in case anyone else is interested I attached it. This alone does not allow setting up an inverted y axis (to enable having y axis pointing up like now) but it looks like there is a ‘svg:transform’ attribute for that. Inverting the axis would also require things like flipping text, I think? (svg:transform reference: http://www.w3.org/TR/SVG/coords.html#SVGGlobalTransformAttribute ) Maybe it helps if we can agree on how coordinate systems should be defined in the svg and how inkscape should display units and rulers? I feel like I haven't really understood all issues. ** Attachment added: viewbox with origin in the center of the page https://bugs.launchpad.net/inkscape/+bug/170049/+attachment/3551689/+files/viewbox-test.svg -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/170049 Title: Inverted ruler co-ordinate system To manage notifications about this bug go to: https://bugs.launchpad.net/inkscape/+bug/170049/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

@jarl-arntzen: Thanks. Even though I spent many days trying to get this little bit of patch working (mainly because of lack of experience), I'm not sure if this idea of mine will be an accepted solution and make it into the official build. I'm not against receiving money but especially in this case it is probably better spent for something else. If I continue to improve this does not depend on money but rather on some dev's opinions if this makes sense. And I hope this will be soon as I will have very little time from April on. Anyway, I will write an email to the dev mailing list and try to get some attention to the topic there. Can someone give a hint where money is needed most? Servers, build infrastructure?

[Bug 170049] Re: Inverted ruler co-ordinate system
I have partly implemented what I described in #57, I still have work to do on the GUI elements. See attached image for how it could look like (this is also the easiest to implement that I can think of for now). @lemasney: I did not quite understand, click and drag on that corner then moves the origin? Or is the origin set where the mouse drag is released? Your suggestion from #61 could be used in addition, good idea. -- Scaling of offset/origin -- In which units should the origin be specified? It could use the 'default units' or the same ones as in the page size settings, but this would in general not match the rulers. If it was scaled by the ruler multiplier it would also change when the multiplier was changed. -- Grid origin -- It probably often makes sense to specify the grid origin relative to the ruler origin. But sometimes you may want to keep an existing grid steady while just moving the ruler origin, so should there be an option for each grid to choose either 'relative to ruler origin' or 'absolute position'? I will try to fix a few remaining gui glitches and will report back within a few days. ** Attachment added: possible user interface https://bugs.launchpad.net/inkscape/+bug/170049/+attachment/3521809/+files/ruler-ui-suggestion.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/170049 Title: Inverted ruler co-ordinate system To manage notifications about this bug go to: https://bugs.launchpad.net/inkscape/+bug/170049/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 170049] Re: Inverted ruler co-ordinate system
I tried to simply add a multiplier and an offset for each ruler which seems to work as expected. (I did not yet manage to link scalar input values of the gui to the actual values but this should not be hard.) This idea could solve the problem of some users I guess, however there would be a few open questions or issues: - should new grids by default have their origin set at the current ruler origin? - coordinates in the svg are not influenced, it's just the ruler numbers that change - what's the best way to integrate in the gui? 4 number input fields for multipliers and offsets could be used - for my default A4 page, setting an inverted y axis requires the user to enter a non integer ruler offset, that's not user friendly at all - with this solution, an inverted y axis might introduce precision issues due to a double transformation - an advantage is compatibility, nothing changes (except additional metadata how to display the rulers) Would this be an acceptable solution?
