[bugzilla-daemon]

https://bugs.documentfoundation.org/show_bug.cgi?id=92152

--- Comment #16 from Regina Henschel  ---
An arrow head is defined independent of the line to which it will be attached
and the definition of the arrow head has no means to reference the prospective
line width. The only way to have some influence on the arrow head is by its
width. Therefore a left arrow cannot align with the right edge of the line
stroke in all cases.

The proposed arrow will always align with the middle of the line stroke, which
produces a corner with thick lines. Unfortunately I see no way to workaround
this problem. If you shift the arrow a little bit to the right, that will only
fit for a special line-width/arrow-head-width combination. It is a question,
whether we should produce such solution "fit best for line-width 0.02cm"
(0.02cm only as example). Currently it is a "fit best for hairline" solution.

Created attachment 127272

Screenshot, how Karbon shows this arrow heads

The proposal in https://gerrit.libreoffice.org/#/c/28603/1 has problems.

Some coordinates in svg:d are outside the range given by svg:viewbox.
LibreOffice can handle this, but other applications not. We should avoid it for
interoperability, as there is no reason for describing the path in this way.
The attachment is a screenshot from Karbon (Calligra Suite).

The path has two Move commands at the beginning. That makes no sense. It will
produce an additional irregular point, when you produce a meta file and break
it up.

I can't see how it will turn into a half arrow head. Wouldn't that render as
full arrow head.

Looks good from my side but we need one half above the line and another below
("Half Arrow Top", "Half Arrow Bottom").

Requested in bug 93782 are inverted arrows and antenna symbol/bird leg like
arrowheads. Would be good if we can close both tickets at once.

Leif's half arrow in 0.2, 1, and 5cm size

Nice work, Leif!

Or above vs. below the line in respect to start or end point. This version is
above on the right/end side and below at left/start. Additionally, it looks
like an imperfect placement, esp. when zoomed or at large size. 

Attaching a PDF for the lazy.

I have searched a little bit. "half arrowhead" is used:

(mostly drawn filled)
single electron movement
"magnetic north" symbol

(mostly drawn as line)
chemical equilibrium
UML asynchronous message

Search for black/white images and the above phrases give some useful results.

Connecting head and line should work best for a ratio of line width 0.02cm to
arrow head width 0.3cm. That is the ratio assumed in the code. Your proposal
seems a little bit off in that ratio.

In your proposal the arrow head is on the left side. Looking at the pictures I
have seen, it seems that a version with arrow head on the right side is needed
too.

Your path has two zero movements. Why?

pdf-export has an additional line on the right side. I do not know why. It
might be an error in the pdf export.

Let's keep it under needsUXeval until finished. Its a design only work and the
ux people should take an eye onto. Mentoring means primarily to commit.

Yes it is easy. In a first step a volunteer can design such arrow head. There
exists the files standard.soe and arrowhd.soe in the installed LibreOffice in
share > palette. There you can add a new line end. It will be available in your
installation and you can test it. And then attach the changed file to this
issue for discussion.

In a second step UX can decide whether such arrow is useful for all users and
important enough to make it always available, then it can be added to official
standard.soe; or if only important for few but advanced users, then to
arrowhd.soe. Of cause then with a proper patch in Gerrit.

Needed skills (besides compiling and use of Gerrit): Know how to write a SVG
path manually. The two files can work as example how such arrow heads are
defined.

We would need it above and below. Is this an EASYHACK?
