<div class="block">Stores the appropriate pixel data that represents the specified
 32-bit integer representation of a color in the buffer
 at the specified coordinates.
 The 32-bit integer will contain the 4 color components in separate
 8-bit fields in ARGB order from the most significant byte to the least
 significant byte.
 The buffer should be positioned to the start of the pixel data such
 that <code>buf.get(0)</code> would return the pixel information for the
 pixel at coordinates <code>(0, 0)</code>.
 The <code>scanlineStride</code> parameter defines the distance from the pixel
 data at the start of one row to the pixel data at the start of the
 immediately following row at the next higher Y coordinate.  Usually,
 <code>scanlineStride</code> is the same as the width of the image multiplied
 by the number of data elements per pixel (1 for the case of the
 integer and indexed formats, or 3 or 4 in the case of the byte
 formats), but some images may have further padding between rows for
 alignment or other purposes.
 <p>
 Color components can be composed into an integer using the following
 sample code:
 <pre>
     int argb = ((alpha &lt;&lt; 24) |
                 (red   &lt;&lt; 16) |
                 (green &lt;&lt;  8) |
                 (blue       );
 </pre></div>
<dl>
<dt><span class="paramLabel">Parameters:</span></dt>
<dd><code>buf</code> - the buffer of pixel data</dd>
<dd><code>x</code> - the X coordinate of the pixel to be read</dd>
<dd><code>y</code> - the Y coordinate of the pixel to be read</dd>
<dd><code>scanlineStride</code> - the number of buffer elements between the
        start of adjacent pixel rows in the buffer</dd>
<dd><code>argb</code> - a 32-bit value with the color to be stored in the pixel
        in a format similar to the <code>Type.INT_ARGB</code> pixel format</dd>
