The &str-XZ; Standard Application Font Names are a set of generic X Window
|
|
System font names, usable by applications as their default
|
|
fonts, for the most common categories of type designs and styles.
|
|
These names, for at least six sizes of 13 typefaces,
|
|
must be provided on all &str-XZ;
|
|
systems, and they should be provided in any
|
|
X server product on which &str-XZ; applications are expected to run.
|
|
They are typically mapped to existing fonts on the system
|
|
using the font alias mechanism, although this method is not required.

<Title>DESCRIPTION</Title>
|
|
<Para>&str-XZ; 1.0 does not come with a common set of fonts on all vendors'
|
|
systems, and both &str-XZ; itself and &str-XZ; applications must be able to run
|
|
on X servers and X terminals from non-&str-XZ; vendors if those vendors so
|
|
desire.
|
|
Therefore, there are a standard set of ``generic'' font names
|
|
and sizes that each &str-XZ; vendor makes available on their &str-XZ; systems and
|
|
that X server vendors may make available on their X servers and
|
|
terminals.
|
|
The names map to existing fonts on each vendor's system,
|
|
which may vary from vendor to vendor.
|
|
</Para>
|
|
<Para>The &str-XZ; Standard Application Font Names described here allow
|
|
applications to use a single set of default font specifications in their
|
|
<Emphasis>app-defaults</Emphasis> files, without concern for the system
|
|
or X server
|
|
on which &str-XZ; is running.
|
|
These
|
|
<Emphasis>app-defaults</Emphasis> application defaults are given as XLFD font name patterns that will
|
|
match the standard &str-XZ; font names on all &str-XZ; systems.
|
|
This allows
|
|
application developers both to reduce their concern with selecting
|
|
their default fonts from a varying set of fonts on different &str-XZ;
|
|
systems and to make use of the system default fonts.
|
|
</Para>
|
|
<RefSect2>
|
|
<Title>Background</Title>
|
|
<Para>Application fonts are the fonts used within an application, where a
|
|
wide variety of text designs, styles, weights and point sizes are useful.
|
|
These variations are used for emphasis, cross-references,
|
|
section headers, and so forth.
|
|
There are thousands of fonts available in the
|
|
market for use in applications, and different &str-XZ; systems will have
|
|
different fonts.
|
|
The standard names attempt to provide the minimum
|
|
variety in generic designs, styles and sizes that an application might
|
|
want to use as defaults.
|
|
(The &str-XZ; Standard Interface Font Names, described in
|
|
&cdeman.DtStdInterfaceFontNames;, provide a similar mechanism for the elements of the &str-XZ; desktop itself.)
|
|
</Para>
|
|
<Para>Common application font names prevent applications
|
|
from needing different
|
|
<Emphasis>app-defaults</Emphasis> files on each &str-XZ; system.
|
|
The Standard Application Font Names
|
|
allow applications to use a single
|
|
<Emphasis>app-defaults</Emphasis> file across all &str-XZ; systems.
|
|
In addition, any X server or X
|
|
terminal vendor may ensure that &str-XZ; applications can run on their
|
|
X server by mapping these standard application names to fonts of the
|
|
corresponding style on their individual X systems.
|
|

|

<RefSect2>
|
|
<Title>Rationale</Title>
|
|
<Para>Two of the most common design variations in fonts used to display text
|
|
are the presence or absence of serifs and the choice between
|
|
proportional or regularly spaced (mono-spaced) characters.
|
|
Combining these two design variations yields four ``generic'' font
|
|
designs, or families:

in four styles (combinations of weight and slant):

|
|
</ItemizedList>
|
|
<Para>The four styles of each of the four design variations yield 16 generic
|
|
font variations.
|
|
These 16 generic fonts are among the most commonly
|
|
used in general desktop computing.
|
|
For example, taking the first three
|
|
real examples above (Times Roman, Helvetica, Courier), these 12 fonts,
|
|
along with the Symbol font, constitute the so-called ``Adobe 13'' that
|
|
is a de facto minimum set of fonts in the PostScript community in the
|
|
desktop computer marketplace.
|
|
</Para>
|
|
<Para>In some cases, applications do not care about the exact font family or
|
|
name to be used, but do need to use a mono-spaced font, a sans serif
|
|
font or a serif font.
|
|
This &str-XZ; mechanism allows such applications to
|
|
be freed from the need to be concerned about the exact font names that
|
|
may or may not be present on a particular &str-XZ; system.

<Title>The Standard Names for the Latin-1 Character Set</Title>
|
|
<Para>The 13 standard application font names are provided on all &str-XZ; systems
|
|
only for the
|
|
ISO 8859
|
|
(Latin-1) character set.
|
|
These represent 12
|
|
generic design and style variations (serif and sans serif
|
|
proportionally-spaced, and a mono-spaced font that is either serif or
|
|
sans serif), as well as a symbol font.
|
|
These standard names are
|
|
provided in addition to the ``real'' names of the fonts that the
|
|
standard names are mapped to for a particular &str-XZ; system.
|
|
An additional four standard font names, to allow both serif and sans serif
|
|
designs in a mono-spaced font, may also be provided by a &str-XZ; system.

behavior for applications, systems should ensure that the

mapping of these standard names as long as all 13 names map to fonts of

the appropriate design and style and the required six point sizes are

<Title>Font Names in app-defaults Files</Title>
|
|
<Para>An application can use a single
|
|
<Emphasis>app-defaults</Emphasis> file to specify font resources and use it across all &str-XZ; systems.
|
|
Since most of the fields (
|
|
<SystemItem Class="Constant">FOUNDRY</SystemItem>, <SystemItem Class="Constant">FAMILY_NAME</SystemItem>, <SystemItem Class="Constant">WEIGHT_NAME</SystemItem>, <SystemItem Class="Constant">SLANT</SystemItem>, <SystemItem Class="Constant">SETWIDTH_NAME</SystemItem>, <SystemItem Class="Constant">ADD_STYLE_NAME</SystemItem>, <SystemItem Class="Constant">POINT_SIZE</SystemItem>, <SystemItem Class="Constant">SPACING</SystemItem>, <SystemItem Class="Constant">CHARSET_REGISTRY</SystemItem> and
|
|
<SystemItem Class="Constant">CHARSET_ENCODING</SystemItem>) of the standard names are the same across different systems,
|
|
these values can be used in the resource specification in the
|
|
<Emphasis>app-defaults</Emphasis> file.
|
|
However, other fields (
|
|
<SystemItem Class="Constant">PIXEL_SIZE</SystemItem>, <SystemItem Class="Constant">RESOLUTION_X</SystemItem>, <SystemItem Class="Constant">RESOLUTION_Y</SystemItem> and
|
|
<SystemItem Class="Constant">AVERAGE_WIDTH</SystemItem>) may vary across
|
|
systems, and so must be wild-carded in the resource specification.
|
|
For example:

<para>The standard application font names defined above can be used for locales other than the

ISO 8859 character set with the following exceptions and differences. For the

following locales, CDE guarantees that systems provide fonts with the following

XLFD attribute values, and that they be accessible using these names.

<Title>NOTES</Title>
|
|
<Para>There is no requirement on a &str-XZ; system to implement these
|
|
standard names in a particular way.
|
|
Several mechanisms are possible:
|
|
duplicate font files with altered naming attributes, X11R5 font
|
|
aliases, or vendor-specific mechanisms.
|
|
The only requirement is that
|
|
an XLFD pattern, written with attributes taken from the set that define
|
|
the standard names, can be successfully used to open a font with the
|
|
Xlib function
|
|
<Function>XLoadFont</Function>; and, specifically, the Xlib function
|
|
<Function>XListFonts</Function> need NOT return the same XLFD names for the pattern on
|
|
different &str-XZ; systems.
|
|
</Para>
|
|
<Para>&str-XZ; applications should, of course, be written to behave in a
|
|
reasonable manner if these standard font names are not available on a
|
|
particular X server.
|
|
This is typically done in an X application by
|
|
defaulting to the
|
|
<Literal>fixed</Literal> and
|
|
<Literal>variable</Literal> fonts.
