And now also pulled in the Debian packaging (for now only uploading in
Debian experimental, will reach Ubuntu 19.10 only most likely).

[ionut stoica]

@yharrow man, can you bring back your patch from the dust, even if it is
just visual/fake representation, it still is something, do you have link
somewhere ?

@kednar it is good in this state, it was in Triaged since 2003, I am not
here to complain, but instead of adding new ui and new buttons, this
would really be nice to give a little bit of attention :D ... I am not
an experienced developer, I am sure it is not a trivial thing, lets just
hope for the best.

I am willing to pay for this a small amount, if anyone tells how we can
support this, a crowd funded stuff such as gofundme or alike, what do
you guys think ?

Thanks and many bows to the mighty Inkscape!

When you use Gimp to translate mockup to code that uses OpenGL coordinates (Y 0

Right now, i'm just flipping the image on Y...

I'd like to see this change too. Every other design program I've used
has had the origin at top left because that is how we read a page (top
to bottom). This isn't a mathematical graph we're wanting to draw here

@ 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.

[yharrow]

@vaifrax

While I do understand your approach as a programmer. From a design
perspective (particularly web-design in which the bottom is not always
clearly defined) it's often easier to think of coordinates as
originating from the top left corner. Creating web design mock-ups in
inkscape without the ability to see this kind of coordinate display is
rather inconvenient.

The feature being requested here is to at least offer a *visual option*
for users to observe the coordinate system as starting at the top left.
Nothing needs to change in the background. Plugins can still use the old
coordinate system and plugin developers can view the coordinate system
however they want.

@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.

[Desktop-packages] [Bug 170049] Re: Inverted ruler co-ordinate system

[Thorjelly]

This might seem very naive, but why do you actually have to change the
internal coordinate system? Can't you add an option in user preferences
or document preferences, which in the latter case could be added as
metadata to not affect backwards compatibility, to where 0,0 should be
and have it only affect the user interface? Simply translate what
coordinates are displayed for an object in the user interface, without
changing the internal coordinate system. This should be an extremely
simple mathematical translation, and the coordinates can be translated
back internally when the document is saved so no internal coordinates
need to change, and no previous documents need to be broken. I'm sure
there are already translations for object coordinates for specific
formats when they are saved since SVG files assume 0,0 is top left.

This seems like a perfectly fine and elegant solution; it even seems
like it should be preferential to me than implementing a system where
all internal coordinates are absolute and revolve around a user-given
origin, because a user changing the origin doesn't also change every
single coordinate in the file, it only changes how coordinates are
displayed in the user interface. To me it seems preferential, because
any coordinate system change only affects the mathematical translation
and not every single point in the system.

I'm literally just talking about translating the x and y values
displayed to the user in the top bar by adding a function. What is wrong
with this solution?

[timfinley24]

I was wondering if this is still an issue. I am currently using .48 and
don't want to hassle if it wont fix it. I've been using inkscape for
years and love it. I have only recently noticed that this is an issue.
If there were a python script out there, that would be cool. I'm not
very versed in coding, otherwise I would do it myself.

Thanks for the hard work and the great product! I hope you can pull
something together with your legal team for that project. I do know
about working for something passionately and going broke because of your

I love all that you (and team) do, always. I use Inkscape every day,
and love all of it, even the parts that are not perfect, because it's free,
it's ours, and if I wanted to, I could learn how to fix it myself. I
certainly
would not complain about any piece of open source software not being
exactly as I wanted it, since the point of open source software is that
I can make it precisely as I wish at any time. I have that ability.

Thank you.

[Jayson Bourne]

Having read all that is written here over several years I came to the
following conclusion:

Surely somewhere someone must be sitting laughing at us, because they know 
something we don't.
Every time someone tries to address this issue it gets shot down. Without 
explanation!
The developers don't seem to need the correct SVG coordinate system, and don't 
care to fix it for their users.

Half the people on here are now willing to pay to get this working and I
am sure there are or will be pay-for apps out there that comply to the
SVG spec regarding this issue.

It is ok to say your application has been downloaded x-million times,
but how many of those people uninstalled it shortly afterwards because
of unfixed bugs like this?

I'm outta here... This is not worth the effort.

Keep your broken-ware!

Jayson

[Desktop-packages] [Bug 170049] Re: Inverted ruler co-ordinate system

[vaifrax]

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.

[Desktop-packages] [Bug 170049] Re: Inverted ruler co-ordinate system

[Krzysztof Kosinski]

The patch by vaifrax does not address the actual issue, which is that
Inkscape internally uses 'desktop coordinates' in many places. These
'desktop coordinates' are hardcoded as an Y-grows-upwards system that
starts at the bottom left corner of the page. A proper solution will be
composed of two parts:

1. Remove the dependence on the desktop-to-document transformation from all 
code that deals with document elements rather than UI elements
2. Provide an UI to set an arbitrary zoom transform (e.g. scaling + 
translation) as the desktop-to-document transformation.

The patch from vaifrax does only 2 and only partially, since it does not
actually change the desktop-to-document transformation, but tacks on an
extra transformation between some of the UI controls and the desktop
coordinates. This approach further complicates things and is untractable
in the long run.

Furthermore, fixing this problem requires removing or significantly
rewriting support for 3D boxes, which contain a fatal bug and write
desktop coordinates to the SVG.

[Desktop-packages] [Bug 170049] Re: Inverted ruler co-ordinate system

[vaifrax]

@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? Support for meetings for developers?

@vaifrax: Hi! I havn't been able to build this on my system yet due to
other commitments. I would however like to pay you for your efforts so
far and I'd like to encourage you to keep up the good work. I'll pay my
original pledge now and make a new one so you can keep on improving
this.

However, when I attempt to make the payment on FreedomSponsors.org, I
get this error message:

"The programmer(s) who solved this issue do not have a verified Paypal account 
yet, so you cannot pay them at this time.
Please leave a comment for them, asking them to update their profile page with 
an email of a verified Paypal account, then come back here again."

Have you added your PayPal account info to FreedomSponsors.org?

I rewrote the gui code and hopefully fixed all issues, please test.
Use the patch or branch 
https://code.launchpad.net/~vaifrax/inkscape/bugfix170049

future work:
- for convenience, add buttons to set origin relative to page (see #62)
- for convenience, add draggable origin (see #61, #63)
- use origin as default for new grids
- optionally specify guides relative to this origin

[Desktop-packages] [Bug 170049] Re: Inverted ruler co-ordinate system

[vaifrax]

@lemasney: here is a partially working first step to a possible solution which 
only affects rulers and mouse pointer status coordinates:
https://code.launchpad.net/~vaifrax/inkscape/bugfix170049
You can find text boxes in the document properties; in the current state 
keyboard input does not always trigger an update, make sure to subsequently 
click on the spinner buttons (up/down) to trigger the update.
Thanks for testing.

My attempt rewriting the GUI part currently fails with a crash, I guess
it will still take me some time to finish.

@vaifrax: Cool stuff. I look forward to testing this out. The main task
is to make the origin move at all and to make sure that the  rest of the
app still works as it should. E.g. moving origin to top left corner and
then enter some positive numeric x/y values should work but I'm willing
to test any partial solution towards that too.

Re: [Desktop-packages] [Bug 170049] Re: Inverted ruler co-ordinate system

[lemasney]

So to be clear. Where the vertical ruler and the horizontal ruler meet in
the upper left hand corner, click and drag out as though you were dropping
a grid line. Instead of a grid line, you'd set the origin of the ruler. It
would also set the origin of the grid. Units and other measurements should
be inherited from the document settings.

[Desktop-packages] [Bug 170049] Re: Inverted ruler co-ordinate system

[vaifrax]

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.

Re: [Desktop-packages] [Bug 170049] Re: Inverted ruler co-ordinate system

[lemasney]

It's my pleasure. In regards to the way in which it should be implemented,
it's been resolved in other systems, like Corel Draw, with a click and drag
from corner where rulers meet to set origin. I think this would work
perfectly.

Vaifrax - below is an attempted patch which may give you approach
insight.
https://bugs.launchpad.net/inkscape/+bug/170049/+attachment/1261051/+files
/invert-ruler-v1.diff

I know it broke others things, but not exactly sure what.   After that
there has been no real effort described.

Just so you understand, each person's bounty may have slightly different
requirements, so review them.

Maybe they can be fully combined into a single spec.   Also, some of us
only require an install or a working version, while others require the
fix to be in an approved released.

I'm willing to pay for a reasonably stable working version . . .

I'll try to write some out some basic requirements for my needs . . .
give me several days to get back to you.

[Desktop-packages] [Bug 170049] Re: Inverted ruler co-ordinate system

[vaifrax]

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? How should the gui look like?

  The y-axis of the rulers' co-ordinate system is

Re: [Desktop-packages] [Bug 170049] Re: Inverted ruler co-ordinate system

[paul]

Thanks for the feedback . . .

Thinking out loud, I'm willing to put a bounty pledge in if someone on the
Inkscape dev leadership team can come up with scope.

Anyone interested in seeing if we can "crowd fund" this issue to the point
we get leading stakeholders of Inkscape involved ? ? ?

In the meanwhile, i'll look into FreedomSponsors . . . when I have a
chance.

Hi everyone. I need this bug/feature so much that I'm willing to pay 30.00 
bucks for it.

 Once you solve it (according to the acceptance criteria described there), just 
create a FreedomSponsors account and mark it as resolved (oh, you'll need a 
Paypal account too)
 I'll then check it out and will gladly pay up!

Well. One proposal could be to put a bounty on FreedomSponsors.org . Let's
put it there and make some noise :) . Gimp will get a vastly improved
resizing tool thanks to sponsors there.

I've had this gripe with Inkscape for as long as I've used it too. I'm
coping, thought, no problem.
Actually, I'm using Inkscape as the main editor in my work as a UI designer
for the last 1.5 years and I'm pretty happy with the results. For me, it's
clearly time to pay back that favour, even in hard cash.

7 years watching this.   I concur, its sad this is not addressed.  It is
a block on following SVG standards and a block of serious nag to many
would be user's.

What can us non-dev folks do to help make this happen?

Hi devs, very sad to see this fall down. I wonder if there can be a
different way to solve this?
