Summary: Enhancement: _outer_ text glow in Writer without font
typography/glyph distortion
Product: LibreOffice
Version: 25.2.4.3 release
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: enhancement
Priority: medium
Component: Writer
Assignee: [email protected]

Description:
Hi!
What I was looking for (it is the idea of an enhancement):
A text with _outer_ glow of a particular color, where font typography is not
distorted and glow spread width is approximately one third+ of a character in
the text. Along with that text programmatically, from a machine driven parser's
perspective, is a consistent single text flow across all the document.
It means for a human, for example, in case of white glow and white
page/background that text will look same with text without the effect. It is
important. When such the text is over a background image, the font typography
(characters glyph) is same with all text in the document. Allowing an image to
be in a background without a distraction. Same time an inserted OLE-like
objects are too complex for parsers to extract the text from a third-party
object and put the text properly back into a middle of text flow in main ODT
content.
In LibreOffice Writer 25.2.4.3 I had a look at Insert->Fontwork feature.
What I found:
All the effects are a sum of inner+outer glow. As the result such the text have
a distorted font typography when the stroke line is wide enough to provide easy
distinguish of the text over image. Slim lines are hard to be distinguished for
an eyes when a picture in background. And thick stroke is covering inner area
of the characters glyph, changing the font drastically.
When there is a background image, in order to have an easy readable text the
glow size must be on the same order of magnitude as the glyph thickness. When
'Insert->Fontwork' suggest ten times less (an order of magnitude less) than it
is needed, _if_ a font distraction is kept unnoticeable. Same time a shadow is
not surrounding a glyph from all sides.
Steps to Reproduce:
1. Enter a long text.
2. Put a background image in the middle of the page. Image size is half size of
the text.
3. Try to use "Insert->Fontwork" or "Format->Character..." to get a font glyph
undistorted. Along with the text still can be read and distinguished easily.
And the text flow is not split into parts from different
compartments/sections/objects. When a text from a programmatical perspective is
a content from a single object, making it easier for parsing.
4. Background of the text outside of the image should be the clear page itself,
without any text glow or an effect.
Actual Results:
You can not achieve the desired result. The font glyph is wiped by inner glow
of the glyph, the stroke line is inside glyph too.
Expected Results:
The font glyph stroke line of a particular color is drew only outside of the
glyph. The stroke line is not overlapping the glyph. Also so called "outer
glow" feature.
Reproducible: Always
User Profile Reset: Yes
Additional Info:
The rationale:
In order to have impressive and easy readable text, with a graphics background
behind, there is a need in _outer_only_ text glow with relatively big width
(one half of character glyph size) of a color same with page color. That allows
the text to go over the image without attention and impression distraction.
I.e. the effect is separating the background image into attention background,
while keeping the main - the text should be easy readable.
I.e. such the effect allows to put an image like an emblem into middle of a
page and do not distract a thing. But provide an impression. Great feature, but
not available with Insert->Fontwork.

Insertions of objects like LibreOffice-Impress/Gimp/Inkscape/Scribus insertions
are not good with modern practice of automated documents parsing of an inbox
with the dumb software. A document is dropped by a robots only because a robot
was not able to find pivot text information over the images as a part of
consistent text flow was too complex for machine-driven inbox parsers (it
produces broken texts with mess).
All that robots (now aka AI) are an industrialisation like steam engines 200
years ago, they are here for ages or forever from now. And the idea of the
enhancement is how to adopt better just today, when the bots are dumb and are a
barrier in a middle of a human communication.
