[news.eclipse.platform.swt] Re: Get color under mouse position

["Grant Gayed" <grant_gayed@xxxxxxxxxx>]

Hi Oliver,

You do this by getting the pixel from the Image's ImageData.  This is
demonstrated in swt's ImageAnalyzer example, method
#showColorForPixel(int,int).  The easiest way to get this source is to
connect to dev.eclipse.org (step 1 of http://www.eclipse.org/swt/cvs.php )
and retrieve the org.eclipse.swt.examples project from HEAD.
