 converts it to a 32-bit integer representation of the color in the
 <a href="../../../javafx/scene/image/PixelFormat.Type.html#INT_ARGB"><code>INT_ARGB</code></a> format.
 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>
 The color components can be extracted from the returned integer using
 the following sample code:
 <pre>
     int alpha = ((retval >> 24) & 0xff);
     int red   = ((retval >> 16) & 0xff);
     int green = ((retval >>  8) & 0xff);
