<A NAME="TranslateMatrix()"><!-- --></A><H3>
TranslateMatrix</H3>
<PRE>
public <B>TranslateMatrix</B>()</PRE>
<DL>
<DD>Create a TranslateMatrix object. This constructor is used when 
 this class is used to translate the matrix of the target in reponse
 to specific positioning relative to some origin. Typically used in a Drag operation.</DL>

TranslateMatrix</H3>
<PRE>
public <B>TranslateMatrix</B>(float&nbsp;deltaX,

<DL>
<DD>Create a TranslateMatrix object. This constructor is used when 
 this class is used to translate the matrix of the target by some
 specified delta each time the transformMatrix method is called. 
 Typically used with the MatrixAction class.<DD><DL>
<DT><B>Parameters:</B><DD><CODE>deltaX</CODE> - the amount of pixels on the x axis the target will be translated.<DD><CODE>deltaY</CODE> - the amount of pixels on the y axis the target will be translated.</DL>
