<p>Sets the pattern's transformation matrix to . </p>
<p>This matrix is a transformation from user space to pattern space.</p>
<p>When a pattern is first created it always has the identity matrix for its transformation matrix, which means that pattern space is initially identical to user space.</p>
<p>Important: Please note that the direction of this transformation matrix is from user space to pattern space. This means that if you imagine the flow from a pattern to user space (and on to device space), then coordinates in that flow will be transformed by the inverse of the pattern matrix.</p>
<p>For example, if you want to make a pattern appear twice as large as it does by default the correct code to use is:</p>
<div class="fragment"><div class="line">pattern->set_matrix(scaling_matrix(0.5, 0.5));</div>
</div><!-- fragment --><p>Meanwhile, using values of 2.0 rather than 0.5 in the code above would cause the pattern to appear at half of its default size.</p>
<p>Also, please note the discussion of the user-space locking semantics of set_source(). </p>
