-  <h3>
-    2. Managing glyph images:
-  </h3>
-
-  <p>The glyph image that is loaded in a glyph slot can be converted into
-     a bitmap, either by using <tt>FT_LOAD_RENDER</tt> when loading it, or
-     by calling <tt>FT_Render_Glyph</tt>. Each time you load a new glyph
-     image, the previous one is erased from the glyph slot.</p>
-    
-  <p>There are times however where you may need to extract this image from
-     the glyph slot, in order to cache it within your application, and
-     even perform additional transforms and measures on it before converting
-     it to a bitmap.
-  </p>
-
-  <p>The FreeType 2 API has a specific extension which is capable of dealing
-     with glyph images in a flexible and generic way. To use it, you first need
-     to include the "<tt>ftglyph.h</tt>" header file, as in:</p>
-     
-  <pre><font color="blue">
-      #include &lt;freetype/ftglyph.h&gt;
-  </font></pre>
-
-  <p>We will now explain how to use the functions defined in this file:</p>
-  
-  <h4>a. Extracting the glyph image:</h4>
-
-  <p>You can extract a single glyph image very easily. Here's some code
-     that shows how to do it:</p>
-
-  <pre><font color="blue">
-       FT_Glyph    glyph;    <font color="gray">// handle to glyph image</font>
-       
-       ....
-       error = FT_Load_Glyph( face, glyph, FT_LOAD_NORMAL );
-       if (error) { .... }
-       
-       error = FT_Get_Glyph( face->glyph, &glyph );
-       if (error) { .... }
-  </font></pre>
-
-  <p>As you see, we have:</p>
-  
-  <ul>
-     <li><p>
-       Created a variable, named <tt>glyph</tt>, of type <tt>FT_Glyph</tt>.
-       This is a handle (pointer) to an individual glyph image.
-     </p></li>
-         
-     <li><p>
-       Loaded the glyph image normally in the face's glyph slot. We did not
-       use <tt>FT_LOAD_RENDER</tt> because we want to grab a scalable glyph
-       image, in order to later transform it.
-     </p></li>
-
-     <li><p>
-       Copy the glyph image from the slot into a new <tt>FT_Glyph</tt> object,
-       by calling <tt><b>FT_Get_Glyph</b></tt>. This function returns an error
-       code and sets <tt>glyph</tt>.
-     </p></li>
-  </ul>
-  
-  <p>It is important to note that the extracted glyph is in the same format
-     than the original one that is still in the slot. For example, if we're
-     loading a glyph from a TrueType font file, the glyph image will really
-     be a scalable vector outline.</p>
-
-  <p>You can access the field <tt><b>glyph->format</b></tt> if you want to
-     know exactly how the glyph is modeled and stored. A new glyph object can
-     be destroyed with a call to <tt><b>FT_Done_Glyph</b></tt>.</p>
-
-  <p>The glyph object contains exactly one glyph image and a 2D vector
-     representing the glyph's advance in 16.16 fixed float coordinates.
-     The latter can be accessed directly as <tt><b>glyph->advance</b></tt>
-     </p>
-
-  <p><font color="red">Note that unlike
-     other FreeType objects, the library doesn't keeps a list of all
-     allocated glyph objects. This means you'll need to destroy them
-     yourself, instead of relying on <tt>FT_Done_FreeType</tt> doing
-     all the clean-up.</font></p>
-     
-  <h4>b. Transforming & copying the glyph image</h4>
-
-  <p>If the glyph image is scalable (i.e. if <tt>glyph->format</tt> is not
-     equal to <tt>ft_glyph_format_bitmap</tt>), it is possible to transform
-     the image anytime by a call to <tt><b>FT_Glyph_Transform</b></tt>.</p>
-     
-  <p>You can also copy a single glyph image with <tt><b>FT_Glyph_Copy</b></tt>.
-     Here's some example code:</p>
-     
-  <pre><font color="blue">
-    FT_Glyph  glyph, glyph2;
-    FT_Matrix matrix;
-    FT_Vector delta;
-    
-    ......
+    <p>The glyph image that is loaded in a glyph slot can be converted into
+    a bitmap, either by using <tt>FT_LOAD_RENDER</tt> when loading it, or by
+    calling <tt>FT_Render_Glyph()</tt> afterwards.  Each time you load a new
+    glyph image, the previous one is erased from the glyph slot.</p>
+
+    <p>There are times, however, where you may need to extract this image

-
-  <h4>c. Measuring the glyph image</h4>
-  
-  <p>You can also retrieve the control (bounding) box of any glyph image
-     (scalable or not), through the <tt><b>FT_Glyph_Get_CBox</b></tt> function,
-     as in:
-     </p>
-
-  <pre><font color="blue">
-     FT_BBox   bbox;
-     ...
-     FT_Glyph_BBox(  glyph, <em>bbox_mode</em>, &bbox );
-  </font></pre>
-
-  <p>Coordinates are relative to the glyph origin, i.e. (0,0), using the
-     Y_upwards convention. This function takes a special argument, the
-     "bbox mode", that is a set of bit flags used to indicate how
-     box coordinates are expressed. If <tt><b>ft_glyph_bbox_subpixels</b></tt>
-     is set in the bbox mode, the coordinates are returned in 26.6 pixels
-     (i.e. 1/64th of pixels). Otherwise, they're in integer pixels.</p>
-
-  <p>Note that the box's maximum coordinates are exclusive, which means
-     that you can always compute the width and height of the glyph image,
-     be in in integer or 26.6 pixels with:</p>
-     
-  <pre><font color="blue">     
-     width  = bbox.xMax - bbox.xMin;
-     height = bbox.yMax - bbox.yMin;
-  </font></pre>
-
-  <p>Note also that for 26.6 coordinates, if
-     <tt><b>ft_glyph_bbox_gridfit</b></tt> is set in the bbox mode,
-     the coordinates will also be grid-fitted, which corresponds to:</p>
-     
-  <pre><font color="blue">
-     bbox.xMin = FLOOR(bbox.xMin)
-     bbox.yMin = FLOOR(bbox.yMin)
-     bbox.xMax = CEILING(bbox.xMax)
-     bbox.yMax = CEILING(bbox.yMax)
-  </font></pre>
-
-  <p>The default value for the bbox mode, which is 0, corresponds to
-     <b><tt>ft_glyph_bbox_pixels</tt></b> (i.e. integer pixel coordinates).</p>

+      <p>Some details on this function's parameters:</p>

+      <ul>
+        <li>
+          The first parameter is <em>the address of the source glyph's

+          a <em>new</em> glyph object that contains the rendered bitmap.
+        </li>
+        <li>
+          The second parameter is a standard render mode that is used to

+        </li>
+        <li>
+          The third parameter is a pointer to a 2d vector that is used to
+          translate the source glyph image before the conversion.  Note that
+          the source image will be translated back to its original position
+          (and will thus be left unchanged) after the call.  If you do not
+          need to translate the source glyph before rendering, set this
+          pointer to&nbsp;0.
+        </li>
+        <li>
+          The last parameter is a Boolean to indicate whether the source

+        </li>
+      </ul>
+
+      <p>The new glyph object always contains a bitmap (when no error is

-    3. Global glyph metrics:
-  </h3>
-  
-  <p>Unlike glyph metrics, global ones are used to describe distances
-     and features of a whole font face. They can be expressed either in
-     26.6 pixels or in design "font units" for scalable formats.</p>
-
-  <h4>
-    a. Design Global Metrics:
-  </h4>
-
-  <p>For scalable formats, all global metrics are expressed in font units
-     in order to be later scaled to device space, according to the rules
-     described in the last chapter of this section of the tutorial. You
-     can access them directly as simple fields of a <tt>FT_Face</tt>
-     handle.</p>
-     
-  <p>However, you need to check that the font face's format is scalable
-     before using them. One can do it by using the macro
-     <tt><b>FT_IS_SCALABLE(face)</b></tt> which returns true when
-     appropriate.</p>
-
-  <p>In this case, you can access the global design metrics as:</p>
-
-  <center><table width="90%" cellpadding=5><tr valign=top><td>
-  <tt><b>units_per_EM</b></tt>
-  </td><td>
-  <p>This is the size of the EM square for the font face. It is used by scalable
-     formats to scale design coordinates to device pixels, as described by the
-     last chapter of this section. Its value usually is 2048 (for TrueType)
-     or 1000 (for Type1), but others are possible too. It is set to 1 for
-     fixed-size formats like FNT/FON/PCF/BDF.</p>
-  </td></tr><tr valign=top><td>
-  <tt><b>global_bbox</b></tt>
-  </td><td>
-  <p>The global bounding box is defined as the largest rectangle that can
-     enclose all the glyphs in a font face. It is defined for horizontal
-     layouts only.</p>
-  </td></tr><tr valign=top><td>
-  <tt><b>ascender</b></tt>
-  </td><td>
-  <p>The ascender is the vertical distance from the horizontal baseline to
-     the highest "character" coordinate in a font face. <em>Unfortunately, font
-     formats define the ascender differently</em>. For some, it represents
-     the ascent of all capital latin characters, without accents, for others
-     it's the ascent of the highest accented character, and finally, other
-     formats define it as being equal to <tt>global_bbox.yMax</tt>.</p>
-  </td></tr><tr valign=top><td>
-  <tt><b>descender</b></tt>
-  </td><td>
-  <p>The descender is the vertical distance from the horizontal baseline to
-     the lowest "character" coordinate in a font face. <em>Unfortunately, font
-     formats define the descender differently</em>. For some, it represents
-     the descent of all capital latin characters, without accents, for others
-     it's the ascent of the lowest accented character, and finally, other
-     formats define it as being equal to <tt>global_bbox.yMin</tt>.
-     <em><b>This field is usually negative</b></em></p>
-  </td></tr><tr valign=top><td>
-  <tt><b>text_height</b></tt>
-  </td><td>
-  <p>This field is simply used to compute a default line spacing (i.e. the
-  baseline-to-baseline distance) when writing text with this font. Note that
-  it usually is larger than the sum of the ascender and descender taken in
-  absolute value. There is also no guarantee that no glyphs can extend
-  above or below subsequent baselines when using this distance.</p>
-  </td></tr><tr valign=top><td>
-  <tt><b>max_advance_width</b></tt>
-  </td><td>
-  <p>This field gives the maximum horizontal cursor advance for all glyphs
-  in the font. It can be used to quickly compute the maximum advance width
-  of a string of text. <em>It doesn't correspond to the maximum glyph image
-  width !!</em></p>
-  </td></tr><tr valign=top><td>
-  <tt><b>max_advance_height</b></tt>
-  </td><td>
-  <p>Same as <tt>max_advance_width</tt> but for vertical text layout. It is
-  only available in fonts providing vertical glyph metrics.</p>
-  </td></tr><tr valign=top><td>
-  <tt><b>underline_position</b></tt>
-  </td><td>
-  <p>When displaying or rendering underlined text, this value corresponds to
-  the vertical position, relative to the baseline, of the underline bar. It
-  noramlly is negative (as it's below the baseline).</p>
-  </td></tr><tr valign=top><td>
-  <tt><b>underline_thickness</b></tt>
-  </td><td>
-  <p>When displaying or rendering underlined text, this value corresponds to
-  the vertical thickness of the underline.</p>
-  </td></tr></table></center>
-  
-  <p>Notice how, unfortunately, the values of the ascender and the descender
-     are not reliable (due to various discrepancies in font formats).</p>       
-  
-  <h4>
-    b. Scaled Global Metrics:
-  </h4>
-
-  <p>Each size object also contains a scaled versions of some of the global
-     metrics described above. They can be accessed directly through the
-     <tt><b>face->size->metrics</b></tt> structure.</p>
-     
-  <p>Note that these values correspond to scaled versions of the design
-     global metrics, <em>with no rounding/grid-fitting performed.</em>.
-     They are also completely independent of any hinting process. In other
-     words, don't rely on them to get exact metrics at the pixel level.
-     They're expressed in 26.6 pixels.</p>
-
-  <center><table width="80%" cellpadding=5><tr valign=top><td>
-  <b><tt>ascender</tt></b>
-  </td><td>
-  <p>This is the scaled version of the original design ascender.</p>
-  </td></tr><tr valign=top><td>
-  <b><tt>descender</tt></b>
-  </td><td>
-  <p>This is the scaled version of the original design descender.</p>
-  </td></tr><tr valign=top><td>
-  <b><tt>height</tt></b>
-  </td><td>
-  <p>This is the scaled version of the original design text height.
-  That probably is the only field you should really use in this structure.</p>
-  </td></tr><tr valign=top><td>
-  <b><tt>max_advance</tt></b>
-  </td><td>
-  <p>Thi is the scaled version of the original design max advance.</p>
-  </td></tr></table></center>
-
-  <p>Note that the <tt><b>face->size->metrics</b></tt> structure contains other
-  fields that are used to scale design coordinates to device space. They're
-  described, in the last chapter.</p>
-
-  <h4>
-    c. Kerning:
-  </h4>  
-  
-  <p>Kerning is the process of adjusting the position of two subsequent
-     glyph images in a string of text, in order to improve the general
-     appearance of text. Basically, it means that when the glyph for an
-     "A" is followed by the glyph for a "V", the space between them can
-     be slightly reduced to avoid extra "diagonal whitespace".</p>
-     
-  <p>Note that in theory, kerning can happen both in the horizontal and
-     vertical direction between two glyphs; however, it only happens in
-     the horizontal direction in nearly all cases except really extreme
-     ones.</p>
-
-  <p>Note all font formats contain kerning information. Instead, they sometimes
-     rely on an additional file that contains various glyph metrics, including
-     kerning, but no glyph images. A good example would be the Type 1 format,
-     where glyph images are stored in a file with extension ".pfa" or ".pfb",
-     and where kerning metrics can be found in an additional file with extension
-     ".afm" or ".pfm".</p>
-     
-  <p>FreeType 2 allows you to deal with this, by providing the
-     <tt><b>FT_Attach_File</b></tt> and <tt><b>FT_Attach_Stream</b></tt> APIs.
-     Both functions are used to load additional metrics into a face object,
-     by reading them from an additional format-specific file. For example,
-     you could open a Type 1 font by doing the following:</p>
-     
-  <pre><font color="blue">
-      error = FT_New_Face( library, "/usr/shared/fonts/cour.pfb", 0, &face );
-      if (error) { ... }
-      
-      error = FT_Attach_File( face, "/usr/shared/fonts/cour.afm" );
-      if (error) { .. could not read kerning and additional metrics .. }
-  </font></pre>
-
-  <p>Note that <tt><b>FT_Attach_Stream</b></tt> is similar to
-     <tt><b>FT_Attach_File</b></tt> except that it doesn't take a C string
-     to name the extra file, but a <tt>FT_Stream</tt> handle. Also,
-     <em>reading a metrics file is in no way, mandatory</em>.</p>
-
-  <p>Finally, the file attachment APIs are very generic and can be used to
-     load any kind of extra information for a given face. The nature of the
-     additional content is entirely font format specific.</p>
-
-  <p>FreeType 2 allows you to retrieve the kerning information between
-     two glyphs through the <tt><b>FT_Get_Kerning</b></tt> function, whose
-     interface looks like:</p>
-     
-  <pre><font color="blue">
-     FT_Vector  kerning;
-     ...
-     error = FT_Get_Kerning( face,                  <font color="gray">// handle to face object</font>
-                             left,                  <font color="gray">// left glyph index</font>
-                             right,                 <font color="gray">// right glyph index</font>
-                             <em>kerning_mode</em>,          <font color="gray">// kerning mode</font>
-                             &kerning );            <font color="gray">// target vector</font>
-  </font></pre>
-
-  <p>As you see, the function takes a handle to a face object, the indices
-     of the left and right glyphs for which the kerning value is desired,
-     as well as an integer, called the "kerning mode", and a pointer to
-     a destination vector that receives the corresponding distances.</p>
-  
-  <p>The kerning mode is very similar to the "bbox mode" described in a
-     previous chapter. It's a enumeration that indicates how the
-     kerning distances are expressed in the target vector.</p>
-     
-  <p>The default value is <tt><b>ft_kerning_mode_default</b></tt> which
-     has value 0. It corresponds to kerning distances expressed in 26.6
-     grid-fitted pixels (which means that the values are multiples of 64).
-     For scalable formats, this means that the design kerning distance is
-     scaled then rounded.</p>
-     
-  <p>The value <tt><b>ft_kerning_mode_unfitted</b></tt> corresponds to kerning
-     distances expressed in 26.6 unfitted pixels (i.e. that do not correspond
-     to integer coordinates). It's the design kerning distance that is simply
-     scaled without rounding.</p>
-     
-  <p>Finally, the value <tt><b>ft_kerning_mode_unscaled</b></tt> is used to
-     return the design kerning distance, expressed in font units. You can
-     later scale it to device space using the computations explained in the
-     last chapter of this section.</p>
-
-  <p>Note that the "left" and "right" positions correspond to the <em>visual
-     order</em> of the glyphs in the string of text. This is important for
-
-     bi-directional text, or simply when writing right-to-left text..</p>

+      3. Global glyph metrics
+    </h3>
+
+    <p>Unlike glyph metrics, global ones are used to describe distances and
+    features of a whole font face.  They can be expressed either in 26.6
+    pixel format or in design <em>font units</em> for scalable formats.</p>
+
+      <h4>
+        a. Design global metrics
+      </h4>
+
+      <p>For scalable formats, all global metrics are expressed in font
+      units in order to be later scaled to device space, according to the
+      rules described in the last chapter of this part of the tutorial.  You
+      can access them directly as simple fields of a <tt>FT_Face</tt>
+      handle.</p>
+
+      <p>However, you need to check that the font face's format is scalable
+      before using them.  One can do it by using the macro
+      <tt>FT_IS_SCALABLE(face)</tt> which returns true if we have a
+      scalable format.</p>
+
+      <p>In this case, you can access the global design metrics as</p>

+
+      <p>Note that the <tt>face->size->metrics</tt> structure contains other
+      fields that are used to scale design coordinates to device space.
+      They are described below.</p>
+
+      <h4>
+        c. Kerning
+      </h4>
+
+      <p>Kerning is the process of adjusting the position of two subsequent
+      glyph images in a string of text, in order to improve the general
+      appearance of text.  Basically, it means that when the glyph for an
+      "A" is followed by the glyph for a "V", the space between them can be
+      slightly reduced to avoid extra "diagonal whitespace".</p>
+
+      <p>Note that in theory, kerning can happen both in the horizontal and
+      vertical direction between two glyphs; however, it only happens in the
+      horizontal direction in nearly all cases except really extreme
+      ones.</p>
+
+      <p>Not all font formats contain kerning information.  Instead, they
+      sometimes rely on an additional file that contains various glyph
+      metrics, including kerning, but no glyph images.  A good example would
+      be the Type&nbsp;1 format, where glyph images are stored in a file
+      with extension <tt>.pfa</tt> or <tt>.pfb</tt>, and where kerning
+      metrics can be found in an additional file with extension
+      <tt>.afm</tt> or <tt>.pfm</tt>.</p>
+
+      <p>FreeType&nbsp;2 allows you to deal with this by providing the
+      <tt>FT_Attach_File()</tt> and <tt>FT_Attach_Stream()</tt> APIs.  Both
+      functions are used to load additional metrics into a face object, by
+      reading them from an additional format-specific file.  For example,
+      you could open a Type&nbsp;1 font by doing the following:</p>
+
+      <font color="blue">
+      <pre>
+    error = FT_New_Face( library,
+                         "/usr/shared/fonts/cour.pfb",
+                         0,
+                         &amp;face );
+    if ( error ) { ... }
+
+    error = FT_Attach_File( face, "/usr/shared/fonts/cour.afm" );
+    if ( error ) { .. could not read kerning and additional metrics .. }</pre>
+      </font>
+
+      <p>Note that <tt>FT_Attach_Stream()</tt> is similar to
+      <tt>FT_Attach_File()</tt> except that it doesn't take a C&nbsp;string
+      to name the extra file, but a <tt>FT_Stream</tt> handle.  Also,
+      <em>reading a metrics file is in no way mandatory</em>.</p>
+
+      <p>Finally, the file attachment APIs are very generic and can be used
+      to load any kind of extra information for a given face.  The nature of
+      the additional data is entirely font format specific.</p>
+
+      <p>FreeType&nbsp;2 allows you to retrieve the kerning information
+      between two glyphs through the <tt>FT_Get_Kerning()</tt> function,
+      whose interface looks like</p>
+
+      <font color="blue">
+      <pre>
+    FT_Vector  kerning;
+
+
+    ...
+    error = FT_Get_Kerning(
+              face,              /* handle to face object */
+              left,              /* left glyph index      */
+              right,             /* right glyph index     */
+              <em>kerning_mode</em>,      /* kerning mode          */
+              &amp;kerning );        /* target vector         */</pre>
+      </font>
+
+      <p>As can be seen, the function takes a handle to a face object, the
+      indices of the left and right glyphs for which the kerning value is
+      desired, as well as an integer, called the <em>kerning mode</em>, and
+      a pointer to a destination vector that receives the corresponding
+      distances.</p>
+
+      <p>The kerning mode is very similar to the <em>bbox mode</em>
+      described in a previous part.  It is an enumeration value that
+      indicates how the kerning distances are expressed in the target
+      vector.</p>
+
+      <p>The default value <tt>ft_kerning_mode_default</tt> (which has
+      value&nbsp;0) corresponds to kerning distances expressed in 26.6
+      grid-fitted pixels (which means that the values are multiples
+      of&nbsp;64).  For scalable formats, this means that the design kerning
+      distance is scaled, then rounded.</p>
+
+      <p>The value <tt>ft_kerning_mode_unfitted</tt> corresponds to kerning
+      distances expressed in 26.6 unfitted pixels (i.e. that do not
+      correspond to integer coordinates).  It is the design kerning distance
+      that is scaled without rounding.</p>
+
+      <p>Finally, the value <tt>ft_kerning_mode_unscaled</tt> is used to
+      return the design kerning distance, expressed in font units.  You can
+      later scale it to device space using the computations explained in the
+      last chapter of this part.</p>
+
+      <p>Note that the "left" and "right" positions correspond to the
+      <em>visual order</em> of the glyphs in the string of text.  This is
+      important for bi-directional text, or simply when writing
+      right-to-left text.</p>

-    5. Advanced text rendering:  transform + centering + kerning:
-  </h3>
-
-  <p>We are now going to modify our code in order to be able to easily
-     transform the rendered string, for example to rotate it. We will
-     start by performing a few minor improvements:</p>
-
-  <h4>a. packing & translating glyphs:</h4>
-  
-  <p>We'll start by packing the information related to a single glyph image
-     into a single structure, instead of parallel arrays. We thus define the
-     following structure type:</p>
-     
-  <font color="blue"><pre>
-     typedef struct TGlyph_
-     {
-       FT_UInt    index;    <font color="gray">// glyph index</font>
-       FT_Vector  pos;      <font color="gray">// glyph origin on the baseline</font>
-       FT_Glyph   image;    <font color="gray">// glyph image</font>
-     
-     } TGlyph, *PGlyph;
-  </pre></font>
-
-  <p>We will also translate each glyph image directly after it is loaded
-     to its position on the baseline at load time. As we'll see, this
-     as several advantages. Our glyph sequence loader thus becomes:</p>

+      <p>Some remarks:</p>
+
+      <ul>
+        <li>
+          The pen position is expressed in the cartesian space (i.e.
+          Y&nbsp;upwards).
+        </li>
+        <li>
+          We call <tt>FT_Glyph_To_Bitmap()</tt> with the <tt>destroy</tt>
+          parameter set to&nbsp;0 (false), in order to avoid destroying the
+          original glyph image.  The new glyph bitmap is accessed through
+          <tt>image</tt> after the call and is typecasted to a
+          <tt>FT_BitmapGlyph</tt>.
+        </li>
+        <li>
+          We use translation when calling <tt>FT_Glyph_To_Bitmap()</tt>.
+          This ensures that the <tt>left</tt> and <tt>top</tt> fields of the
+          bitmap glyph object are already set to the correct pixel
+          coordinates in the cartesian space.
+        </li>
+        <li>
+          Of course, we still need to convert pixel coordinates from
+          cartesian to device space before rendering, hence the
+          <tt>my_target_height - bitmap->top</tt> in the call to
+          <tt>my_draw_bitmap()</tt>.
+        </li>

+
+    <h3>
+      5. Advanced text rendering: transformation + centering + kerning
+    </h3>
+
+    <p>We are now going to modify our code in order to be able to easily
+    transform the rendered string, for example to rotate it.  We will start
+    by performing a few minor improvements:</p>
+
+      <h4>
+        a. packing & translating glyphs
+      </h4>
+
+      <p>We start by packing the information related to a single glyph image
+      into a single structure instead of parallel arrays.  We thus define
+      the following structure type:</p>
+
+      <font color="blue">
+      <pre>
+    typedef struct  TGlyph_
+    {
+      FT_UInt    index;    /* glyph index                  */
+      FT_Vector  pos;      /* glyph origin on the baseline */
+      FT_Glyph   image;    /* glyph image                  */
+
+     } TGlyph, *PGlyph;</pre>
+      </font>
+
+      <p>We will also translate each glyph image directly after it is loaded
+      to its position on the baseline at load time, which has several
+      advantages.  Our glyph sequence loader thus becomes:</p>
+
+      <font color="blue">
+      <pre>
+    FT_GlyphSlot  slot = face->glyph;  /* a small shortcut */
+    FT_UInt       glyph_index;
+    FT_Bool       use_kerning;
+    FT_UInt       previous;
+    int           pen_x, pen_y, n;
+
+    TGlyph        glyphs[MAX_GLYPHS];  /* glyphs table           */
+    PGlyph        glyph;               /* current glyph in table */
+    FT_UInt       num_glyphs;
 
-   <p>Note that translating glyphs now has several advantages. The first
-      one, is that we don't need to translate the glyph bbox when we compute
-      the string's bounding box. The code becomes:</p>

-
-  <p>This code is the basis of the FreeType 2 demonstration program

-  <p>Note however that a normal implementation would use a glyph cache in

-    6. Accessing metrics in design font units, and scaling them:
-  </h3>
-
-  <p>Scalable font formats usually store a single vectorial image, called
-     an "outline", for each in a face. Each outline is defined in an abstract
-     grid called the "design space", with coordinates expressed in nominal
-     "font units". When a glyph image is loaded, the font driver usually
-     scales the outline to device space according to the current character
-     pixel size found in a <tt>FT_Size</tt> object. The driver may also
-     modify the scaled outline in order to significantly improve its
-     appearance on a pixel-based surface (a process known as "hinting"
-     or "grid-fitting").</p>
-     
-  <p>This chapter describes how design coordinates are scaled to device
-     space, and how to read glyph outlines and metrics in font units. This
-     is important for a number of things:</p>
-     
-  <ul>
-    <li><p>
-      In order to perform "true" WYSIWYG text layout
-    </p></li>
-    
-    <li><p>
-      In order to access font content for conversion or analysis purposes
-    </p></li>
-  </ul>
 
-  <h4>a.Scaling distances to device space:</h4>
-  
-  <p>Design coordinates are scaled to device space using a simple scaling
-     transform, whose coefficients are computed with the help of the
-     <em><b>character pixel size</b></em>:</p>
-     
-  <pre><font color="purple">
-     device_x = design_x * x_scale
-     device_y = design_y * y_scale
-
-     x_scale  = pixel_size_x / EM_size
-     y_scale  = pixel_size_y / EM_size
-  </font></pre>
-
-  <p>Here, the value <b><tt>EM_size</tt></b> is font-specific and correspond
-     to the size of an abstract square of the design space (called the "EM"),
-     which is used by font designers to create glyph images. It is thus
-     expressed in font units. It is also accessible directly for scalable
-     font formats as <tt><b>face->units_per_EM</b></tt>. You should
-     check that a font face contains scalable glyph images by using the
-     <tt><b>FT_IS_SCALABLE(face)</b></tt> macro, which returns true when
-     appropriate.</p>
-
-  <p>When you call the function <tt><b>FT_Set_Pixel_Sizes</b></tt>, you're
-     specifying the value of <tt>pixel_size_x</tt> and <tt>pixel_size_y</tt>
-     you want to use to FreeType, which will immediately compute the values
-     of <tt>x_scale</tt> and <tt>y_scale</tt>.</p>
-
-  <p>When you call the function <tt><b>FT_Set_Char_Size</b></tt>, you're
-     specifying the character size in physical "points", which is used,
-     along with the device's resolutions, to compute the character pixel
-     size, then the scaling factors.</p>
-
-  <p>Note that after calling any of these two functions, you can access
-     the values of the character pixel size and scaling factors as fields
-     of the <tt><b>face->size->metrics</b></tt> structure. These fields are:</p>
-     
-  <center>
-  <table width="80%" cellpadding="5"><tr valign=top><td>
-  <b><tt>x_ppem</t></b>
-  </td><td>
-  <p>Which stands for "X Pixels Per EM", this is the size in integer pixels
-  of the EM square, which also is the <em>horizontal character pixel size</em>,
-  called <tt>pixel_size_x</tt> in the above example.</p>
-  </td></tr><tr valign=top><td>
-  <b><tt>y_ppem</tt></b>
-  </td><td>
-  <p>Which stands for "Y Pixels Per EM", this is the size in integer pixels
-  of the EM square, which also is the <em>vertical character pixel size</em>,
-  called <tt>pixel_size_y</tt> in the above example.</p>
-  </td></tr><tr valign=top><td>
-  <b><tt>x_scale</tt></b>
-  </td><td>
-  <p>This is a 16.16 fixed float scale that is used to directly
-  scale horizontal distances from design space to 1/64th of device pixels.
-  </p>
-  </td></tr><tr valign=top><td>
-  <b><tt>y_scale</tt></b>
-  </td><td>
-  <p>This is a 16.16 fixed float scale that is used to directly scale
-  vertical distances from design space to 1/64th of device pixels.</p>
-  </td></tr>
-  </table>
-  </center>
-
-  <p>Basically, this means that you can scale a distance expressed in
-     font units to 26.6 pixels directly with the help of the <tt>FT_MulFix</tt>
-     function, as in:</p>
-     
-  <pre><font color="blue">
-      <font color="gray">// convert design distances to 1/64th of pixels
-      //</font>
-      pixels_x = FT_MulFix( design_x, face->size->metrics.x_scale );
-      pixels_y = FT_MulFix( design_y, face->size->metrics.y_scale );
-  </font></pre>
-  
-  <p>However, you can also scale the value directly with more accuracy
-     by using doubles and the equations:</p>
-     
-  <pre><font color="blue">
-      FT_Size_Metrics*  metrics = &face->size->metrics;    // shortcut
-      double            pixels_x, pixels_y;
-      double            em_size, x_scale, y_scale;
-
-      <font color="gray">// compute floating point scale factors
-      //</font>
-      em_size = 1.0 * face->units_per_EM;
-      x_scale = metrics->x_ppem / em_size;
-      y_scale = metrics->y_ppem / em_size;
-      
-      <font color="gray">// convert design distances to floating point pixels
-      //</font>
-      pixels_x = design_x * x_scale;
-      pixels_y = design_y * y_scale;
-  </font></pre>
-  
-  <h4>
-    b. Accessing design metrics (glyph & global):
-  </h4>
-  
-  <p>You can access glyph metrics in font units simply by specifying the
-     <tt><b>FT_LOAD_NO_SCALE</b></tt> bit flag in <tt>FT_Load_Glyph</tt>
-     or <tt>FT_Load_Char</tt>. The metrics returned in
-     <tt>face->glyph->metrics</tt> will all be in font units.</p>
-  
-  <p>You can access unscaled kerning data using the
-     <tt><b>ft_kerning_mode_unscaled</b></tt> mode</p>
-
-  <p>Finally, a few global metrics are available directly in font units
-     as fields of the <tt>FT_Face</tt> handle, as described in chapter 3
-     of this section.</p>

-  <h3>
-    Conclusion
-  </h3>
-  
-  <p>This is the end of the second section of the FreeType 2 tutorial,
-     you're now able to access glyph metrics, manage glyph images, and
-     render text much more intelligently (kerning, measuring, transforming
-     & caching).</p>
-  
-  <p>You have now sufficient knowledge to build a pretty decent text service

+
+      <ul>
+        <li>
+          We keep the original glyph images untouched, by transforming a
+          copy.
+        </li>
+        <li>
+          We perform clipping computations in order to avoid rendering &
+          drawing glyphs that are not within our target surface.
+        </li>
+        <li>
+          We always destroy the copy when calling
+          <tt>FT_Glyph_To_Bitmap()</tt> in order to get rid of the
+          transformed scalable image.  Note that the image is destroyed even
+          when the function returns an error code (which is why
+          <tt>FT_Done_Glyph()</tt> is only called within the compound
+          statement).
+        </li>
+        <li>
+          The translation of the glyph sequence to the start pen position is

+        </li>
+      </ul>
+
+      <p>It is possible to call this function several times to render the
+      string width different angles, or even change the way <tt>start</tt>
+      is computed in order to move it to different place.</p>
+
+      <p>This code is the basis of the FreeType&nbsp;2 demonstration program
+      named <tt>ftstring.c</tt>.  It could be easily extended to perform
+      advanced text layout or word-wrapping in the first part, without
+      changing the second one.</p>
+
+      <p>Note however that a normal implementation would use a glyph cache
+      in order to reduce memory consumption.  For example, let us assume
+      that our text string to render is "FreeType".  We would store three
+      identical glyph images in our table for the letter "e", which isn't
+      optimal (especially when you consider longer lines of text, or even
