<div class="refsect1">
<a name="gdk-Fonts.description"></a><h2>Description</h2>
<p>
The <a class="link" href="gdk-Fonts.html#GdkFont" title="GdkFont"><span class="type">GdkFont</span></a> data type represents a font for drawing on
the screen. These functions provide support for
loading fonts, and also for determining the dimensions
of characters and strings when drawn with a particular
font.
</p>
<p>
Fonts in X are specified by a
<em class="firstterm">X Logical Font Description</em>.
The following description is considerably simplified.
For definitive information about XLFD's see the
X reference documentation. A X Logical Font Description (XLFD)
consists of a sequence of fields separated (and surrounded by) '-'
characters. For example, Adobe Helvetica Bold 12 pt, has the
full description:
</p>
<div class="informalexample">
  <table class="listing_frame" border="0" cellpadding="0" cellspacing="0">
    <tbody>
      <tr>
        <td class="listing_lines" align="right"><pre>1</pre></td>
        <td class="listing_code"><pre class="programlisting"><span class="string">"-adobe-helvetica-bold-r-normal--12-120-75-75-p-70-iso8859-1"</span></pre></td>
      </tr>
    </tbody>
  </table>
</div>

<p>
</p>
<p>
The fields in the XLFD are:
</p>
<div class="informaltable"><table width="100%" border="0">
<colgroup>
<col>
<col>
</colgroup>
<tbody>
<tr>
<td>Foundry</td>
<td>the company or organization where the font originated.</td>
</tr>
<tr>
<td>Family</td>
<td>the font family (a group of related font designs).</td>
</tr>
<tr>
<td>Weight</td>
<td>A name for the font's typographic weight
For example, 'bold' or 'medium').</td>
</tr>
<tr>
<td>Slant</td>
<td>The slant of the font. Common values are 'R' for Roman,
'I' for italoc, and 'O' for oblique.</td>
</tr>
<tr>
<td>Set Width</td>
<td>A name for the width of the font. For example,
'normal' or 'condensed'.</td>
</tr>
<tr>
<td>Add Style</td>
<td>Additional information to distinguish a font from
other fonts of the same family.</td>
</tr>
<tr>
<td>Pixel Size</td>
<td>The body size of the font in pixels.</td>
</tr>
<tr>
<td>Point Size</td>
<td>The body size of the font in 10ths of a point.
(A <em class="firstterm">point</em> is 1/72.27 inch) </td>
</tr>
<tr>
<td>Resolution X</td>
<td>The horizontal resolution that the font was designed for.</td>
</tr>
<tr>
<td>Resolution Y</td>
<td>The vertical resolution that the font was designed for .</td>
</tr>
<tr>
<td>Spacing</td>
<td>The type of spacing for the font - can be 'p' for proportional,
'm' for monospaced or 'c' for charcell.</td>
</tr>
<tr>
<td>Average Width</td>
<td>The average width of a glyph in the font. For monospaced
and charcell fonts, all glyphs in the font have this width</td>
</tr>
<tr>
<td>Charset Registry</td>
<td>The registration authority that owns the encoding for
the font. Together with the Charset Encoding field, this
defines the character set for the font.</td>
</tr>
<tr>
<td>Charset Encoding</td>
<td>An identifier for the particular character set encoding.</td>
</tr>
</tbody>
</table></div>
<p>
</p>
<p>
When specifying a font via a X logical Font Description,
'*' can be used as a wildcard to match any portion of
the XLFD. For instance, the above example could
also be specified as
</p>
<div class="informalexample">
  <table class="listing_frame" border="0" cellpadding="0" cellspacing="0">
    <tbody>
      <tr>
        <td class="listing_lines" align="right"><pre>1</pre></td>
        <td class="listing_code"><pre class="programlisting"><span class="string">"-*-helvetica-bold-r-normal--*-120-*-*-*-*-iso8859-1"</span></pre></td>
      </tr>
    </tbody>
  </table>
</div>

<p>
It is generally a good idea to use wildcards for any
portion of the XLFD that your program does not care
about specifically, since that will improve the
chances of finding a matching font.
</p>
<p>
A <em class="firstterm">fontset</em> is a list of fonts
that is used for drawing international text that may
contain characters from a number of different character
sets. It is represented by a list of XLFD's.
</p>
<p>
The font for a given character set is determined by going
through the list of XLFD's in order. For each one, if
the registry and and encoding fields match the desired
character set, then that font is used, otherwise if
the XLFD contains wild-cards for the registry and encoding
fields, the registry and encoding for the desired character
set are substituted in and a lookup is done. If a match is found
that font is used. Otherwise, processing continues
on to the next font in the list.
</p>
<p>
The functions for determining the metrics of a string
come in several varieties that can take a number
of forms of string input:
</p>
<div class="variablelist"><table border="0">
<col align="left" valign="top">
<tbody>
<tr>
<td><p><span class="term">8-bit string</span></p></td>
<td><p>
    When using functions like <a class="link" href="gdk-Fonts.html#gdk-string-width" title="gdk_string_width ()"><code class="function">gdk_string_width()</code></a> that
    take a <span class="type">gchar *</span>, if the font is of type
    <a class="link" href="gdk-Fonts.html#GDK-FONT-FONT:CAPS"><code class="literal">GDK_FONT_FONT</code></a> and is an 8-bit font, then each
    <span class="type">gchar</span> indexes the glyphs in the font directly.
    </p></td>
</tr>
<tr>
<td><p><span class="term">16-bit string</span></p></td>
<td><p>
    For functions taking a <span class="type">gchar *</span>, if the
    font is of type <a class="link" href="gdk-Fonts.html#GDK-FONT-FONT:CAPS"><code class="literal">GDK_FONT_FONT</code></a>, and is a 16-bit
    font, then the <span class="type">gchar *</span> argument is
    interpreted as a <span class="type">guint16 *</span> cast to
    a <span class="type">gchar *</span> and each <span class="type">guint16</span>
    indexes the glyphs in the font directly.
    </p></td>
</tr>
<tr>
<td><p><span class="term">Multibyte string</span></p></td>
<td><p>
    For functions taking a <span class="type">gchar *</span>, if the
    font is of type <a class="link" href="gdk-Fonts.html#GDK-FONT-FONTSET:CAPS"><code class="literal">GDK_FONT_FONTSET</code></a>, then the input
    string is interpreted as a <em class="firstterm">multibyte</em>
    encoded according to the current locale. (A multibyte
    string is one in which each character may consist
    of one or more bytes, with different lengths for different
    characters in the string). They can be converted to and
    from wide character strings (see below) using
    <a class="link" href="gdk-Fonts.html#gdk-wcstombs" title="gdk_wcstombs ()"><code class="function">gdk_wcstombs()</code></a> and <a class="link" href="gdk-Fonts.html#gdk-mbstowcs" title="gdk_mbstowcs ()"><code class="function">gdk_mbstowcs()</code></a>.) The string will
    be rendered using one or more different fonts from
    the fontset.
    </p></td>
</tr>
<tr>
<td><p><span class="term">Wide character string</span></p></td>
<td><p>
    For a number of the text-measuring functions, GDK
    provides a variant (such as <a class="link" href="gdk-Fonts.html#gdk-text-width-wc" title="gdk_text_width_wc ()"><code class="function">gdk_text_width_wc()</code></a>) which
    takes a <span class="type">GdkWChar *</span> instead of a
    <span class="type">gchar *</span>. The input is then taken to
    be a wide character string in the encoding of the
    current locale. (A wide character string is a string
    in which each character consists of several bytes,
    and the width of each character in the string is
    constant.)

<pre class="programlisting">typedef guint32			    GdkWChar;
</pre>
<p>
Specifies a wide character type, used to represent character codes.
This is needed since some native languages have character sets which have
more than 256 characters (Japanese and Chinese, for example).
</p>
<p>
Wide character values between 0 and 127 are always identical in meaning to
the ASCII character codes. The wide character value 0 is often used to
terminate strings of wide characters in a similar way to normal strings
using the char type.
</p>
<p>
An alternative to wide characters is multi-byte characters, which extend
normal char strings to cope with larger character sets. As the name suggests,
multi-byte characters use a different number of bytes to store different
character codes. For example codes 0-127 (i.e. the ASCII codes) often
use just one byte of memory, while other codes may use 2, 3 or even 4 bytes.
Multi-byte characters have the advantage that they can often be used in an
application with little change, since strings are still represented as arrays
of char values. However multi-byte strings are much easier to manipulate since
the character are all of the same size.
</p>
<p>
Applications typically use wide characters to represent character codes
internally, and multi-byte strings when saving the characters to a file.
The <a class="link" href="gdk-Fonts.html#gdk-wcstombs" title="gdk_wcstombs ()"><code class="function">gdk_wcstombs()</code></a> and <a class="link" href="gdk-Fonts.html#gdk-mbstowcs" title="gdk_mbstowcs ()"><code class="function">gdk_mbstowcs()</code></a> functions can be used to convert from
one representation to the other.
</p>
<p>
See the 'Extended Characters' section of the GNU C Library Reference Manual
for more detailed information on wide and multi-byte characters.
