<h2>Description</h2>
<p>Use DrawImage() to draw a graphic primitive on your image. The primitive
may be represented as a string or filename. Precede the filename with an
"at" sign (@) and the contents of the file are drawn on the image. You
can affect how text is drawn by setting one or more members of the draw
info structure.</p>
<p>Note that this is a legacy interface. Authors of new code should consider
using the Draw* methods defined by magick/draw.h since they are better
documented and less error prone.</p>
