I assume you are using 4 bytes per pixel with no lf or spaces in  
between.

You might want to check the height & width and formattedHeight &  
formattedWidth.

Also, I have seen cases when funny things happen when the total size  
is not as expected.  It goes completely wacko.

That may be why I clear the image and set the height and width before  
setting the imageData.  Or is it set height & width, then clear the  
data?  Or maybe...
