Ok, I see... well, in that case, I have to open a separate bug about
positioning/coordinate precision that's not specific to text glyph
positioning... some of you on the CC list may be interested in 152079, and
sorry for the spam.

Yes, though I think this is done selectively (e.g. inside the documents but not
for UI text, or something like that). There are quite a few bug reports that
track this.

Ah, so coordinates are now scaled fixed-point? Or is it just something being

This bug is about subpixel glyph positioning, floating point coordinates is one
way to fix it but it isn’t going to happen and we now have achieved this using
something closer to what is described in comment 14.

Tahoma example text in LO 5.1, 7.1, and 7.4

I hope the attached image helps.  To me, at least, the kerning issue appears
resolved in LO 7.4.  Previously, I had _mostly_ noticed kerning issues around
punctuation in the Tahoma font, as you can see in the attached image of text
taken from the same document as rendered in PDF (which pretty well shows
something more than just a sub-pixel issue).  You can also see that 7.4 is
nearly the same as 5.1 with some minor sub-pixel differences.  Kerning between
letters (such as "fa") also appears better.

I looked at the previous mention of "California" in Liberation Sans, 12pt, 120%
zoom, and it appears better as well in 7.4--although, that "rn" will likely
always be a bit hard to discern.

I agree with Aron’s comment above. I think folks are overemphasizing what kind
of issues this change can fix. To be honest, I don’t expect it to fix any
glaring issues any more, possibly only subtler sub-pixel positioning issues.

A lot of issues associated with this enhancement should be fixed in 7.4 by
Caolán's fix to bug 144862. Would be good to systematically retest these bugs,
and if they're indeed fixed, mark as duplicates of that, and clean up the see
also/duplicate/blocked bugs.

"California" rendered in Liberation Serif at 12pt, 120% zoom on my screen

During some work on related Bug 142940, I came across a particularly bad
example of the issues caused by this bug and wanted to add it as an example.

It's the single word "California" rendered in Liberation Serif at 12pt, 120%
zoom on my screen. In this case, among many other issues, the renderer has
chosen to place the 'r' and 'n' characters so close together that they actually
overlap and appear to be an 'm'. It's a good illustration of how the lack of
subpixel positioning for glyphs ruins any attempt at proper kerning.

Incidentally, the related bug is about the fact that disabling pair kerning
ameliorates some of these problems. In this case, an extra pixel is placed
between the 'r' and 'n', probably because kerning nudges them slightly closer
together and creates situations where rounding will force them to overlap.

This specific image was created with a script I wrote to rerender a screenshot
as virtual subpixels with the same RGB alignment as my actual screen, and then
point upscaled three times. This allows users who may be on very different
screens to see exactly what rendering decisions Libreoffice + Fontconfig is
making for my screen.

--- Comment #37 from gibt...@gmx.de ---
I noticed that using FreeType and HarfBuzz in OpenCV, it is possible to write
strings with integer precision to images that look absolutely fine. Still, the
whole string is put as a whole to the image, please refer to the OpenCV
documentation for or details:
https://docs.opencv.org/3.4/d9/dfa/classcv_1_1freetype_1_1FreeType2.html

Thus I thought that the reason for this ugly rendering might simply be that
LibreOffice splits the whole strings into individual characters that are 
written individually? For example, instead of writing "Hello world!" as a
whole, LibreOffice puts all chars/glyphs "H", "e", "l", "l", "o", etc. one
after another and recalculates the glyph position every time again in integer
arithmetic only? Even if the latter was replaced by floats, I don't know if
this even fixes the problem if HarfBuzz still uses integers for the initial
rendering of the string... I don't know LibreOffice's code, still if FreeType /
HarfBuzz is used correctly, rounding issues coming from integer instead of
floating point accuracy should only influence the initial position of the
string (i.e. a whole line of text), but not between characters / words.
I might be wrong, still this seems rather plausible to me such that a fix might
be even easier than migrating all of LibreOffice's code to floats...

Libre Calc, toggling between good and bad kerning

In Libre Calc, pressing F2 to edit text produces mostly-accurate kerning until
editing mode is escaped. See attachment.

--- Comment #33 from Telesto  ---
FYI, I'm inclined to blame:
fdo#52028: sw: let text formatting ignore RSID in automatic styles
A suprising regression from 062eaeffe7cb986255063bb9b0a5f3fb3fc8e34c:
The RSID text attributes that are inserted for every user-inserted text
cause the text formatting (SwAttrIter) to create a lot more text portions,
and the portion breaks make font kerning impossible.

based on bug 140161. The whole floating point topic might not solve the issue
at all.

Hey it took me a while but I finally found this bug.

I experience this too, on Linux, and it's really debilitating - it's why I
still run MS Office through Wine.

Is using floating point numbers going to be much of an issue?

Artifact when scrolling text

Adding this image to this bug because the one I opened depends on it. It shows
an artifact that I get when I scroll a document: text gets deformed, with
elongated characters, often unaligned. I think it's related to the problem with
using integers rather than floating points for glyph positioning.

--- Comment #21 from gibt...@gmx.de ---
I also noticed this bug and finally found this thread... Two points from my
side: First, I do not really understand how this is a desktop scaling / HiDPI
bug? For me this would mean that at 100% desktop scaling this issue should not
appear, or am I wrong here? I also tested two different Full HD screens and an
old 1280x1024 screen that all use desktop scaling 100% (here I'm referring to
the 100% scale that can be configured under Windows' screen properties) - and
the issue is definitely visible. How can this happen if it is a HiDPI issue?

And then my second question, where I'm especially referring to Rachel's
comment. I didn't look into the code, but if the whole coordinate stuff has to
be migrated from int to float (or double), wouldn't it be a feasible approach
to start with changing "only" any involved variable definition from int to
float as a first step, without changing anything else? So we would only save
our ints in float-valued variables (maybe introducing implicit cast warnings)
but once done, the positioning code could be migrated step by step to fully
support float?

Also hoping this issue gets fixed soon. Especially for Impress presentations it
can really be a show stopper if the slides are not properly rendered...

[Libreoffice-bugs] [Bug 103322] Use floating point for glyph positioning in VCL

--- Comment #17 from horus  ---
I'm the reporter of bug 113665 which was marked as a duplicate of this bug.

I have tried the following daily builds but the problem described in bug 113665
 is still present:
* libo-master64~2019-05-22_00.57.02_LibreOfficeDev_6.3.0.0.alpha1_Win_x64.msi
* libo-master64~2019-05-29_09.41.50_LibreOfficeDev_6.3.0.0.alpha1_Win_x64.msi
*
master~2019-05-24_22.08.51_LibreOfficeDev_6.3.0.0.alpha1_Win_x64_en-US_de_ar_ja_ru_vec_qtz.msi
*
master~2019-05-29_04.28.58_LibreOfficeDev_6.3.0.0.alpha1_Win_x64_en-US_de_ar_ja_ru_vec_qtz.msi

So, maybe that bug is actually not related to this bug?

Another alternative to floating point, is to keep using integers but use a
scale, so instead of shaping at 10 pixels and drawing at the coordinates we
get, we shape at 10 * SCALE and shape ant coordinates / SCALE. Which is what
many other libraries do, and I vaguely remember that we have something similar
by may be we are not using it thoroughly. Worth investigating.

--- Comment #13 from Rachel Greenham  ---
For me it presents as a HiDPI bug, in that it's when desktop scaling is at
200%, 300%, text (any font) can be quite a reasonable editing size on screen
but show this poor positioning of glyphs within each word, making it
headache-inducing to look at, and actually a serious impediment to wanting to
use the software. Of course it was there before, HiDPI just amplifies it,
making it a problem at larger font sizes as displayed on screen.

As the worst problem is just the positioning of glyphs within words I looked
for the code that does that. It seems to be mostly in
vcl/source/gdi/CommonSalLayout.cxx, where the actual work is delegated to
Harfbuzz, which appears to work in integers, but I think at a very high
resolution (whatever a upem is). The values that then come out of that then
have a scale applied at double, rounded, and I suspect subject to more scaling
later, in particular with respect to the desktop scaling factor in HiDPI modes.
And that's probably where it's going wrong.

I had a play with trying to fix things locally in here and in
vcl/source/gdi/sallayout.cxx, changing all the glyph positioning code to use
doubles (and B2DPoint etc), including changing GlyphItem (sallayout.hxx) to use
those types for its positions, widths and offsets and rounding as necessary at
the edges of that, but I did rather get lost in the weeds, specifically, where
to find the edges of it, to minimise the disruption to the rest of the
codebase.

I suspect a fix can't really be confined like that, and it's probably
undesirable anyway. It looks like we'd probably want to make DeviceCoordinate a
double (as controlled in config_host/config_vcl.h.in showing this has been at
least partially prepared-for) and follow *everywhere* that leads, one such
place being the text functions in outdev.hxx of course.

Then final rounding to integers for actual pixels on screen would probably want
to happen in platform specific code. As absolutely late as possible, at the
moment of output, anyway. Then if and when there's a platform that takes double
coordinates that rounding simply doesn't have to happen there.

Regarding the suggestion of going via B2IPoint and friends as an intermediate
step towards B2DPoint and friends, I note that the B2I types are carefully
defined to use 32-bit ints (sal_Int32), whereas Point, Rectangle et al use long
(which let's face it *is* 64-bit almost everywhere that matters now) as does
much existing position-calculating code. So I'd worry that we'd be setting
ourselves up for a fight to resolve issues relating to that loss of range when
it's only needed as an intermediate step.

... All of which would be an absolutely gigantic changeset, no wonder no-one
who knows the code wants to do it! The more I poked around in this the more I
thought, "Oh God, no..." and "Can we *really* not localise this fix in
sallayout?" :-) But no, ultimately changing *all* the device coordinate code to
double is probably what has to happen one day.

Another thought I had, noticing that in OpenOffice.org Writer on a 4K screen of
course has no HiDPI awareness to speak of, so its user interface is unusable,
but zoom in on the text to an editing size and it looks fine - at 240% zoom you
would expect that, of course. Pretty much the same applies in LibreOffice
Writer if you set your desktop scaling to 100% on a 4K screen. So I wondered,
what if instead you just *not* apply desktop scaling on the document view
panes/frames whatever they're called here, and, um, *lie* on the user
interface, ie: multiply the user selected zoom by the desktop scaling factor?
:-)

I’d start with the “Text functions” section in include/vcl/outdev.hxx and go
down and up from there.

We will need to switch from tools::Point, tools::Rectangle etc. to
basegfx::B2DPoint, basegfx::B2DRectangle, not just int to float/double. May be
using basegfx::B2IPoint first since they are still int-based, so the first
round would focus on the difference in semantics and API between tools and
basegfx, then next round would tackle the actual floating pint conversion.

"I assume the "float" problem lies in the LibreOffice code and not in HarfBuzz,
since HarfBuzz is used in Firefox and Chrome also, which have no problems with
accurate glyph display. Will this "float" bug of LibreOffice be fixed anywhere
