+%  DrawGetTypeMetrics() returns the following information for the specified
+%  font and text:
+%
+%    character width
+%    character height
+%    ascender
+%    descender
+%    text width
+%    text height
+%    maximum horizontal advance
+%    bounds: x1
+%    bounds: y1
+%    bounds: x2
+%    bounds: y2
+%    origin: x
+%    origin: y
+%    underline position
+%    underline thickness
+%
+%  The format of the DrawGetTypeMetrics method is:
+%
+%      MagickBooleanType DrawGetTypeMetrics(const DrawingWand *wand,
+%        const char *text,MagickBooleanType ignore_newlines,
+$        TypeMetric *metrics)
+%
+%  A description of each parameter follows:
+%
+%    o wand: the drawing wand.
+%
+%    o text: text to draw.
+%
+%    o metrics: Return the font metrics in this structure.
+%
+%    o ignore_newlines: indicates whether newlines should be ignored.
+%
+%    o metrics: Return the font metrics in this structure.
