Improvements to Font
Handling
Heiko Tietze
2018

What‘s all the fuss about?
Large number of issues
(yellow/red) and
enhancement requests
(green) regarding fonts
tdf#102985: [META] Font bugs and enhancements
https://www.wordclouds.com/

1. Font substitution
Helvetica DejaVu Sans
Samples taken from http://www.identifont.com

Current solution
Not working in the character dialog

Information 1/3
● Benjamin wants to get the text as close as possible to
the original (and don’t cares about substitution).
● Eve wants to clearly see if the current selection has
been substituted to understand possible differences
(tdf#61134, tdf#94327).
● Eve wants to understand what fonts are substituted in
the current document to make the decision if installing
makes sense, for example (tdf#78186).

Substitution 1/2
● Eve wants to make the current
substitution permanent to use only open
formats in future (tdf#104667)
but restrict to
used only
(tdf#95062).

Substitution 2/2
● Eve wants to manage the font
substitution table to learn how fonts are
replaced and to manipulate the
association (tdf#64509, tdf#94327).

Listing 1/3
● Benjamin wants to select one from the
installed fonts without getting bothered
by too many style variations (tdf#35538,
tdf#66792).

Listing 2/3
● Benjamin wants to hide fonts that are
disabled in the system (tdf#77878) or not
relevant in the context of LibreOffice
(tdf#88416) in order to have a smaller
fonts list (tdf#91130).
Some could be
interesting
temporarily

Listing 3/3
● Benjamin wants to filter the fonts list acc.
all/used/favorite (tdf#101748), highlight
used fonts (tdf#90161) as well as locale
(Chinese for instance) (tdf#114764).
Textmaker Scribus

Installation
● Adrian wants to install fonts to the system
directory to reduce maintanance effort
(tdf#103140).
https://design.blog.documentfoundation.org/2016/11/11/additions-to-libreoffice/

Summary
● Improve font substitution (infobar,
substitution table, dropdown, preview)
● Provide means to hide and to highlight
fonts (options dialog, font selection,
dropdown)
● Make fonts extendible (don‘t bundle any
font, enhance extensions and integrate
with system)

Some basics about typeface
● Serifs (with/without)
● Height (ascender/descender),
Width (spacing/tracking)
●
Proportional/monospaced
● Weight/thickness (thin, light, bold, heavy…)
● Slope/slant (italic or oblique)
● Width (compressed, condensed, expanded...)
● Kerning (e.g. AV), Rotation, ...

A fast-paced introduction to TensorFlow 2 about some important new features (such as generators and the @tf.function decorator) and TF 1.x functionality that's been removed from TF 2 (yes, tf.Session() has retired). Concise code samples are presented to illustrate how to use new features of TensorFlow 2. You'll also get a quick introduction to lazy operators (if you know FRP this will be super easy), along with a code comparison between TF 1.x/iterators with tf.data.Dataset and TF 2/generators with tf.data.Dataset. Finally, we'll look at some tf.keras code samples that are based on TensorFlow 2. Although familiarity with TF 1.x is helpful, newcomers with an avid interest in learning about TensorFlow 2 can benefit from this session.

You want a man who is honest, hardworking, and loyal – not a complainer or a weakling or a self-centred man. You are a strong, independent, sensual, caring, loving woman. And you don’t think it’s asking too much to want to be with a loving, intelligent man with a good sense of humour and daring, an upright and confident man – who knows who he is. No one wants a chauvinistic and macho man, but you do want someone who will be willing to protect and care for you. Who loves you for you and not some kind of imaginary. You have no doubt that when the right guy appears on your doorstep, you’ll never let him go. But sometimes a man doesn’t realize he has that good woman.

Have you found yourself infatuated with a special someone you think could be the one? Are you looking for a spell to provide them with a nudge in the right direction? Or maybe the spell you cast didn’t achieve the results you were hoping for? Whether you’re new or versed in the ways of spell casting, we’re here to help. Today we’re going to provide you with a detailed guide on the types of love spells to cast. Not only that but there’s something for those who wish to find outside advice from more advanced spell casters. We’re also going to provide you with the top sites available to help you with your dilemma. Let’s begin our journey by educating ourselves on love magic and what a real love caster looks like. Love Magic and Love Casters Love magic made its first appearance back in Ancient Egypt and has been an active practice since. This type of magic is a branch of traditional magic and can be practiced in various ways. Typically the more common use of love magic is through the work of spells, but other methods look like Charms Rituals-LOVE Potions-Dolls and even Amulets If you are interested in becoming a love caster, be prepared for what’s to come. A genuine love caster knows that the art of love casting is no easy feat and shouldn’t be done casually. You should know that not only does it require you to be gifted spiritually, but you must be ready to serve others. Someone who is considered a real love caster has experience in all manner of spells, no matter the difficulty. Training yourself in attraction, commitment, and marriage spells is an excellent place to start. But this by no means will make you a professional. Practice your craft and expand your knowledge; understand that you will possess the ability to help others in time truly. Types of Love Spells What better way to start broadening your experiences with love spells than by learning more about them? These spells work like just about any other spell. Simply apply your intention, use a medium (sigils, mantras, candles, or charm bags), and top it off with establishing the belief that you will receive what you want. So what kind of spells are available and which ones suit your needs the best? Let’s take a look at the many options you have at your disposal.
